Asymptomatic Patients With Suspected Coronary Artery Disease: What Are Clinicians Afraid Of?

Antônio Sérgio Cordeiro da Rocha et al. Dany Kruczan

Introduction

In contemporary practice, myocardial revascularization, particularly Percutaneous Coronary Intervention (PCI), is frequently performed in asymptomatic individuals with suspected Coronary Artery Disease (CAD). This occurs despite robust evidence from Randomized Clinical Trials (RCTs) over the past two decades demonstrating that, in patients with Chronic Coronary Syndromes (CCS), neither PCI nor Coronary Artery Bypass Grafting (CABG) reduces mortality when compared with Guideline-directed Medical Therapy (GDMT). In selected populations, revascularization confers symptomatic relief, particularly among patients with frequent angina, but without prognostic advantage.

The persistence of invasive strategies in asymptomatic patients appears to be driven largely by two cognitive biases: the “oculostenotic reflex”, the impulse to correct angiographically visible stenoses, and the “oculoischemic reflex”, the perceived need to revascularize documented ischemia irrespective of symptoms. Both are rooted in the fear that untreated coronary obstructions inevitably herald sudden cardiac death or Acute Myocardial Infarction (AMI).^,

Fernando Maia Coutinho et al. Talles L. Pereira Nogueira Dilma do Socorro Moraes de Souza Lucianna Serfaty de Holanda … Vitor Bruno Teixeira de Holanda Michele N. Assad Rafael M. Coutinho Ana Flávia Oliveira de Souza Márcio César Ribeiro Marvão Thiago da Silva Paulo

Abstract

Background:

Patients with coronary artery disease (CAD) are categorized by cardiovascular risk depending on associated risk factors and events, requiring more rigorous treatment goals.

Objective:

To investigate treatment adherence, using the Morisky–Green test, and achievement of metabolic goals at a tertiary public hospital in Belém, Pará, Brazil.

Methods:

This observational, cross-sectional, and analytical study was conducted with a sample of 106 patients with CAD at very high cardiovascular risk, treated in the outpatient clinic of a tertiary care hospital. The following data were collected over a 4-month period: demographic information, medication adherence (Morisky–Green test), modifiable risk factors, and laboratory parameters (lipids, blood glucose, blood pressure, heart rate, and abdominal circumference). Associations were assessed using chi-square test or G test, and correlations were analyzed using Spearman’s test, adopting a significance level of 5% (p < 0.05).

Results:

Treatment adherence analysis showed an adherence rate of 16.0%. Low-density lipoprotein (LDL) -cholesterol levels were above the target of 50 mg/dL in 72.6% of patients, and normal blood glucose was achieved in 75.5%. Education level was the only epidemiological variable associated with therapeutic non-adherence (p = 0.0130). Regarding financial aspects, only 9.4% reported persistent difficulty in purchasing medications; among those reporting difficulty, high-potency statins were the most frequently cited (58.6%).

Conclusions:

Education level was shown to be a determining factor in understanding treatment, impacting adherence. Laboratory tests revealed significant deficiencies in lipid control, reinforcing the need for clinical optimization. Difficulties in accessing statins and low medication adherence underscore the importance of educational interventions and multidisciplinary approaches for better management of CAD.

Epidemiological Profile of Arterial Hypertension in the Municipality of Rio de Janeiro, Brazil, 2011 and 2019

Catia Martins Cristina Oliveira et al. Anna Carolina Pinho da Silva Bianca Ramos Marins Silva Ana Clara Campos

Abstract

Background:

Cardiovascular diseases are currently the leading global cause of morbidity and premature mortality. High blood pressure is one of the precursors to the disease, which, when undetected, can lead to other serious complications such as thrombosis, acute myocardial infarction, and stroke.

Objective:

To analyze the profile of hypertension and associated factors in the municipality of Rio de Janeiro in the years 2011 and 2019.

Method:

This is a population-based cross-sectional study that used data from the Vigitel telephone survey implemented by the Ministry of Health. The eligible population was that of the municipality of Rio de Janeiro, aged eighteen or older, in 2011 and 2019. To analyze the association between the outcome and the independent variables, multivariate logistic regression was used, estimating the Odds Ratio and its respective 95% confidence intervals.

Results:

The predominant sociodemographic profile remained similar in 2011 and 2019: a majority of women, 18-39 years, and with 9-12 years of schooling. Education level in 2011 appeared as a protective factor among individuals with 12 or more years of schooling (OR: 0.64, 95% CI: 0.43; 0.97). Obese individuals had a 2.81- and 2.96-times greater chance, in 2011 and 2019, respectively, of reporting hypertension, compared to non-obese individuals.

Conclusion:

The study highlights the need to expand the healthcare network to implement more effective strategies that consider the determinants of hypertension in order to achieve a greater impact on the management and control of the disease.

Ketan Inamdar et al. Harshada Kajave Akash Shete Jayant Pawar … Anmaria Thomas Madhur Kulkarni

Abstract

Background:

Coronary artery disease (CAD) continues to be a predominant global cause of morbidity and mortality, with rising prevalence in developing nations like India, emphasizing the need to address risk factors, multimorbidity, and polypharmacy to implement effective lifestyle interventions and drug therapies to enhance patient outcomes.

Objectives:

To evaluate the risk factors, comorbidities, and multiple drug therapy patterns among patients diagnosed with CAD in a tertiary care setting.

Methods:

This prospective observational study used medical records to collect data on demographics, comorbidities, lifestyle factors, and medications. Descriptive statistics summarized findings, and Chi-square tests assessed associations between gender, risk factors, and CAD. The significance level adopted in the statistical analysis was 5%.

Results:

Out of 300 patients enrolled, 69.3% were male, and the highest disease prevalence was noted in the 66–75 age group. Hypertension was the most common comorbidity (71%), followed by diabetes mellitus (DM) (50%). Poor diet was the leading lifestyle risk factor (25.3%), followed by smoking (21%). A significant association existed between gender and CAD type (p = 0.002), with females showing higher angina prevalence and males showing more myocardial infarction (MI). For CAD management, aspirin (92.6%) and enoxaparin (59.3%) were most frequently prescribed, followed by atorvastatin (53.6%) and nicorandil (52%). For comorbidity management, beta-blockers (59.6%) and insulin (48.7%) were commonly prescribed. Increased use of ticagrelor and dapagliflozin was observed, indicating a greater alignment with evidence-based guideline recommendations.

Conclusion:

This study highlights the burden of multimorbidity and polypharmacy among CAD patients in India, emphasizing the need for individualized, evidence-based therapy.

The Relationship Between Obesity and the Risk of Systemic Arterial Hypertension in Children and Adolescents: Lessons Learned

John Jairo Araujo

One out of five children around the world is overweight or obese. This is shown in the meta-analysis published by Zhang X et al. in 2024, which included 2,033 studies from 154 different countries or regions. Although the prevalence of childhood obesity varies between global regions, it is evident that its incidence is growing significantly. According to the latest United Nations International Children’s Emergency Fund (UNICEF) and World Bank estimates, 33.6% of children and adolescents 5-19 years old are affected by overweight or obesity, as are 8% of children under the age of five. Recently, Muyulema SL et al. published the results of global childhood overweight and obesity trends over the last 20 years. In this study, they analyzed 194 countries around the world, showing that the global prevalence of childhood overweight and obesity increased from 5.4% to 5.7% between 2000 and 2022.

Inflammation, Metabolic Syndrome and Systemic Hypertension: “a dangerous and synergistic triad”: Metabolic Syndrome (MS) has been well defined in adults, and includes various conditions like Systemic Arterial Hypertension (SAH), elevated fasting blood sugar levels (greater than 100 mg/dl) or type 2 diabetes mellitus, low HDL cholesterol levels (less than 40 mg/dl in men or 50 mg/dl in women), high triglyceride concentrations (greater than 150 mg/dl), and a waist circumference greater than 101 cm (men) or 90 cm (women). It is not clearly defined in children, due to the imprecision of the various factors that compose it and the changes in different stages of life. However, risk factors like obesity, increased waist circumference (increased visceral fat), insulin resistance, and, in certain cases, lipid profile abnormalities, are compatible with MS, especially in children over the age of 10.

Obstructive Sleep Apnea as a Risk Factor for Ischemic Heart Disease

Soham Samajpaty et al. Alexander Konstantinovich Zhuravlov Emilianovich Dmitrii Ilin Yuriy Sergeivich

Abstract

Background:

Obstructive sleep apnea (OSA) is increasingly recognized as a potential risk factor for ischemic heart disease (IHD), but its role remains underexplored. This study investigated the association between OSA and IHD using a case-control design.

Objectives:

The objective of this study was to establish OSA as a risk factor for developing IHD.

Methods:

A total of 122 participants were recruited and categorized into two groups: patients with a recent history of IHD (< 7 days) (wIHD group, n = 61) and controls without IHD but with hypertension (cIHD group, n = 61). The STOP-Bang questionnaire was used to assess OSA risk, and statistical analyses, including odds ratio (OR), relative risk (RR), and attributable risk (AR), were performed. A significance level of 0.05 was adopted for all statistical analyses.

Results:

Patients in the wIHD group had significantly higher STOP-Bang scores than the control group (p 1). The level of statistical significance was found to be 0.05.

Conclusion:

This study identifies OSA as an important risk factor for IHD, supporting the need for routine OSA screening in cardiovascular risk assessment. Larger studies are needed to further explore this relationship

Comparison Between Two Prevention and Control Programs for Risk Factors for Cardiovascular Diseases in an Oil Company

Maria Lúcia Ribeiro Rocha et al. Ana Marice Teixeira Ladeia

Abstract

Background:

Cardiovascular diseases (CVDs) are the leading cause of death in the world, and companies can implement prevention and control actions aimed at reducing risk factors among their workers.

Objectives:

To verify whether the result of model A of a CVD prevention and control program was superior to model B in reducing the cardiovascular risk (CVR) of individuals from an oil company.

Methods:

Retrospective evaluation of secondary data from a restricted and fixed cohort of 670 workers, from 01/01/2016 to 12/31/2018. The workers were divided by program model into Group A (514) and Group B (156). The 2016 CVR was compared with that of 2018, within and between groups, as well as the mean and prevalence of risk factors for CVD. Statistical analysis was set at a significance level of 5%.

Results:

Group A improved the level of physical activity (PAL), consumption of fruits and vegetables, and consumption of alcohol, but the “high” CVR increased from 0.4% in 2016 to 1.4% in 2018 (p<0.01). In Group B there was no change in the workers’ health profile, but the percentage of individuals with "intermediate" CVR increased from 14.1% to 16.7% (p=0.01).

Conclusions:

The actions developed by the company had a positive impact on the way of life of workers covered by the model A program; however, they were not sufficient to reduce CVR in this group.

Unconventional Anthropometric Indicators: Foundations, Applicability, and Validity as Predictors of Health Conditions

Haroldo da Silva Ferreira et al. Antonio Fernando Silva Xavier Júnior Élison Ruan da Silva Almeida Tainá Cardoso Caminha-Uchôa … Andressa Bruna Batista de Verçoza Hitalo de Moraes Vieira

Abstract

Several anthropometric parameters have been proposed as indicators of health conditions. Some have achieved wide acceptance and applicability. Others, although grounded in solid theoretical frameworks and demonstrating good diagnostic validity, have not gained the same level of recognition. These are referred to here as “unconventional anthropometric indicators”. This article aims to provide a descriptive and conceptual synthesis of these measures, addressing their nuances and applicability. It is a narrative review that discusses the following indicators: Head-to-height index (HHI), Waist-to-Height Ratio (WHtR), Conicity Index (C-Index), Waist-to-Hip Ratio (WHR), A Body Shape Index (ABSI), Neck Circumference (NC), and Adductor Pollicis Muscle Thickness (APMT). WHtR, C-Index, WHR, and ABSI are based on the identification of abdominal fat accumulation and its association with cardiometabolic risks. However, for this purpose, waist circumference stands out due to its methodological simplicity and predictive effectiveness. NC is an indicator of subcutaneous fat, whose excess increases disease risk and is not influenced by factors that alter abdominal volume. APMT identifies muscle depletion and is comparable to other anthropometric predictors of malnutrition risk. HHI was proposed to identify individuals who experienced undernutrition early in life. Grounded in a robust theoretical foundation, it is a promising tool for advancing research on the Developmental Origins of Health and Disease (DOHaD). The indicators analyzed are valuable for monitoring cardiometabolic risk factors, each with its unique characteristics. Understanding these particularities is essential for selecting the most appropriate indicators for different contexts, thus enabling more effective interventions.

Obstructive Sleep Apnea in Acute Myocardial Infarction: A Prognostic Risk Factor beyond Traditional Players?

Carlos Wollmann et al. Luciano F. Drager

The high prevalence of obstructive sleep apnea (OSA) and its worrisome association with various cardiovascular diseases, particularly ischemic heart disease, demand our attention. This common sleep disordered breathing, characterized by partial or complete upper airway obstructions during sleep, profoundly impacts overall health.^, In the cardiovascular context, intermittent hypoxia, sleep fragmentation, and intrathoracic pressure swings promoted by repeated respiratory events during sleep promote several potentially deleterious phenomena, including increased sympathetic activity, blood pressure fluctuations, chronic systemic inflammation, reactive oxygen species production, and endothelial dysfunction.^– These factors create a fertile ground for the development and progression of atherosclerosis,^, significantly increasing the likelihood of ischemic events if the condition remains undetected and untreated.^, However, the relationship between OSA and acute myocardial infarction (AMI) is complex. Patients with OSA often share risk factors that also increase AMI risk, notably age, male sex, and obesity. While some evidence suggests an independent role for OSA in the cardiovascular risk, its contribution remains controversial in high-risk patients with multiple comorbidities. Further research in this area is therefore warranted in order to provide additional insights.

In this issue of the International Journal of Cardiovascular Sciences, Carrijo et al. explore the complex relationship between OSA and traditional risk factors in 145 patients with ST-segment elevation myocardial infarction (STEMI). The authors used employed the widely used STOP-BANG questionnaire to assess OSA risk. The initial results were consistent with previous literature: a high frequency (58.6%) of patients exhibited a high risk for OSA. This highlights the urgent need for increased attention to this comorbidity, particularly in this specific patient population. In the multivariate analysis, the authors found an independent association of OSA with both male sex and hypertension in these patients. The presence of hypertension in OSA patients is not coincidental. Some of the aforementioned mechanisms associated with OSA directly contribute to elevated blood pressure, thereby increasing cardiovascular risk.^,

Impact of Digital Technology Intervention on Medication Compliance, Modification of Risk Factors, and Clinical Outcome in Patients With Acute Coronary Syndrome: A Follow-Up Study

C. J Devaraju et al. S Sunil Kumar K. S. Sadananda K Vinay Kumar … Veena Nanjappa K. S. Rajith K. S. Ravindranath

Abstract

Background

Coronary artery disease (CAD) is prevalent worldwide, presenting significant morbidity and mortality. Despite the advances in the management of CAD, the primary focus continues to be risk factor reduction, lifestyle changes, and medication adherence, all of which contribute considerably to favorable outcomes. Long-term CAD outcomes tend to be poor, especially in developing countries, due to medication non-compliance, a lack of education, and appropriate measures for the modification of risk factors.

Objectives

The present study aims to investigate the use of digital technology in assessing medication compliance, modifying risk factors, and evaluating clinical outcomes in patients with acute coronary syndrome (ACS).

Methods

A prospective, randomized study will be conducted with patients diagnosed with ACS at the Sri Jayadeva Institute of Cardiovascular Disease and Research, Mysore, and JSS Medical College, Mysore, India. A total of 522 patients will be randomized in a 1:1 ratio into either the digital intervention group or the control group. Digital technology registration will be completed during hospitalization, with guidance from the research team. Follow-up assessments will occur every three months for one year. Statistical analysis will be conducted at a 5% significance level. Categorical variables will be analyzed using the Z test for proportions or the Chi-square test, while continuous variables will be assessed using the independent sample t-test.

Results

The results will be presented after data collection and statistical analysis. This study aims to focus on clinical outcomes in patients with ACS, highlighting the importance of lifestyle modification, adherence to medications, and modifications of risk factors by digital technology, bridging the gap between patients and healthcare providers.

Conclusions

We intend for the outcomes of this study to produce an initiative for larger randomized control trials regarding web application in the management of ACS. Favorable outcomes could significantly impact the management of ACS, and web applications can be recommended as part of a routine standard of care established by societal guidelines.

Ludmylla da Silva Soares Carrijo et al. Patricia Magnabosco Maria Beatriz Guimarães Raponi Maria Angélica Melo e Oliveira … Suely Amorim de Araújo Luiz Claudio Martins Valéria Nasser Figueiredo

Abstract

Background

Obstructive sleep apnea (OSA) promotes endothelial dysfunction and systemic inflammation, and it is associated with shorter long-term survival and unfavorable clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI).

Objectives

To investigate the factors associated with the risk of OSA in the aftermath of STEMI.

Methods

A cross-sectional, quantitative study conducted with 145 individuals with STEMI in a large Brazilian teaching hospital. Anthropometric measurements were performed in addition to collecting sociodemographic/clinical data and lifestyle habits. The STOP-BANG questionnaire was used to determine the risk of OSA. The results were analyzed using descriptive statistics, association tests, and logistic regression. A significance level of 5% was adopted for the statistical analysis.

Results

The mean age of the participants was 62 ± 12 years, with a predominance of males (71%), white individuals (57.2%), and those at high risk of OSA (58.6%). Moderate to high risk of OSA was associated with male gender, hypertension, and dyslipidemia. Gender (HR = 6.13, 95% CI [1.88, 20.03], p = 0.003) and hypertension (HR = 4.31, 95% CI [1.27, 14.63], p = 0.019) were factors influencing the risk of OSA after acute myocardial infarction.

Conclusions

Hypertension and male gender were significant factors for a moderate/high risk of OSA in infarcted patients.

Correlation of Diagnostic Components of Metabolic Syndrome with Electrocardiographic and Echocardiographic Alterations in Patients with Obesity

Alan Souza da Luz et al. João Gabriel da Costa Ramos Carolina Heitmann Mares Azevedo Ribeiro Roberto Márcio de Oliveira Júnior … Antônio Carmo da Costa Siqueira Neto Ralf Cardoso Mudesto Oliveira

Abstract

Introduction:

Metabolic syndrome (MS) and obesity are risk factors for cardiovascular diseases (CVD). However, the development of cardiovascular pathologies in obese individuals without MS is being investigated.

Objective:

To investigate whether there are similar electrocardiographic (ECG) and echocardiographic changes in individuals with obesity with and without MS.

Methodology:

A retrospective, descriptive cross-sectional study was carried out with obese patients at a university hospital in Belém, Pará, Brazil. Anthropometric, laboratory, ECG and echocardiographic data were evaluated in both populations. The chi-square test was used to describe the relationship between variables among groups; hypothesis tests with p < 0.05 were considered statistically significant values.

Results:

The study evaluated 100 individuals with obesity, 60 of whom had MS. The average age was 54 years, and the female sex was prevalent. Systolic blood pressure, HDL, and waist circumference were altered in both groups. Systemic arterial hypertension and low HDL demonstrated 4.27 times and 3.32 times greater likelihood of presenting changes in the ECG and echocardiogram for both groups. On the ECG, diffuse changes in ventricular repolarization were observed in both groups. On echocardiography, left ventricular diastolic dysfunction and left ventricular hypertrophy were present in both populations studied.

Conclusion:

Obese individuals without MS present a similar risk, requiring adequate attention to their cardiac health.

Clinical Profile and its Associations with Coronary Angiography Results in a Public University Hospital

Guilherme Costa et al. Esmeralci Ferreira Denilson Campos Albuquerque

Abstract

Background:

Ischemic heart disease is one of the most common causes of death worldwide. There are few data in the literature about the association of clinical profile and coronary angiography results in the Brazilian population.

Objectives:

To assess clinical variables and their associations with the results of coronary angiography and to evaluate the safety of coronary angiography in a public university hospital.

Methods:

From August 2015 to April 2018, 1 844 patients submitted to coronary angiography at the Pedro Ernesto University Hospital (HUPE, acronym in Portuguese) were enrolled in this cross-sectional study. They were evaluated by their clinical variables, angiographic results, and procedure complications. Logistic regression was used, and the criterion for determining significance was set at 5%.

Results:

The median age was 62 years, and most of the population (71%) were outpatients. Stable angina was the most common indication (62.9%). Only 19.7% underwent noninvasive cardiac testing. Arterial hypertension was the most prevalent (88.2%), followed by dyslipidemia (60.2%). Most patients (65%) had obstructive coronary artery disease (CAD). Left main coronary artery (LMCA) stenosis was found in 8.1% of patients. Older age, male sex, quantity of risk factors (RF), and peripheral artery disease were risk predictors for CAD. Death occurred only in 0.16% of the population, and acute coronary artery occlusion in 0.2%.

Conclusion:

Classic RF showed an association with CAD. The low incidence of complications suggests that coronary angiography is a safe procedure to be conducted in a public university hospital.

Risk Factors for In-Hospital Mortality from Cardiac Causes After Acute Myocardial Infarction

Gabriel Vasconcelos Oliveira et al. Maria Beatriz Guimarães Raponi Patricia Magnabosco Maria Angélica Melo e Oliveira … Suely Amorim de Araújo Vanderlei José Haas Valéria Nasser Figueiredo

Abstract

Background:

Risk stratification on admission of patients with acute ST-elevation myocardial infarction (STEMI) is considered a clear strategy for effective treatment, early intervention, and survival.

Objective:

The purpose of this study was to determine the risk factors for in-hospital mortality from cardiac causes after STEMI.

Methods:

Observational, retrospective, longitudinal study, with a quantitative approach, based on data from the medical records of individuals diagnosed with STEMI treated at the Emergency Room of a large hospital in the state of Minas Gerais, Brazil, from January 2011 to July 2016. The outcome of interest was 30-day in-hospital mortality from after STEMI. For statistical analysis, the Pearson’s chi-square test, Spearman’s correlation and multivariable Cox-regression analysis were used, with a significance level of α = 0.05.

Results:

Of the 459 patients, 55 (12%) died from cardiac causes within 30 days after STEMI. Mean admission SBP of these patients was 109.08mmHg. The incidence of death was higher in women (23.7%), patients with systemic arterial hypertension (SAH) (13.8%) and elderly patients (16.5%). The elderly — heart rate (HR) = 3.54 — and women — HR = 2.55 — had a statistically significant higher risk of progressing to death when compared to younger adults and men. The highest admission SBP had a protective effect (HR = 0.97), reducing the chance of death by 3%.

Conclusion:

SBP on admission, female gender and advanced age were significant risk factors for death within 30 days after STEMI.

Coronary Artery Disease in Women: Getting to Know Gender Related Disparities

Ana Gilabert-Garcia et al. Cristina Cristina Villarreal Guerrero Rodrigo Dagio-Cuéllar Jorge Luis Bermudez-Gonzalez … Arantza Marie Perez-Partida Joaquin Berarducci Javier Ivan Armenta-Moreno Jose Luna-Alvarez-Amezquita Juan Ignacio Straface Nilda Espinola-Zavaleta Erick Alexanderson

Abstract

Coronary artery disease (CAD) and ischemic heart disease (IHD) are often indistinctly used terms. Both combined have generated, over the past years, concerns about sex disparities in their presentation. From an epidemiological perspective, females have several disadvantages regarding the prevention, diagnosis, and treatment of CAD. Most of the general cardiovascular risk factors affect women more frequently, or with a higher morbidity and mortality association. Besides, atypical manifestations of the disease and uncommon forms of CAD represent a diagnostic challenge for clinicians. Even if current treatments for CAD have no apparent sex bias, women representation in clinical trials and treatment patterns analyzed in clinical practice refuse this statement. Several disparities are caused by inevitable sex-particularities, but many of them are more social, cultural, and dogmatic beliefs that have to be addressed and overhaul.

Association between the Phytochemical Index and Risk Factors for Cardiovascular Disease in Adults

Vanessa Zanoni Carvalhaes et al. George César Ximenes Meireles Regina Maria Catarino Rosemeire Bueno

Abstract

Background

There are few publications about the association between the phytochemical index (PI) and risk factors for cardiovascular disease.

Objective

To evaluate the association between the PI and risk factors for cardiovascular disease in adults.

Methods

This was a cross-sectional study with 141 adults, between 20 and 59 years of age. We analyzed lifestyle (physical activity), sociodemographic data (sex, age), anthropometric data (body mass index [BMI], waist circumference [WC]), biochemical data (lipid profile, blood glucose), food consumption, and phytochemical intake (expressed as PI = daily energy derived from phytochemical-rich foods ÷ total daily energy intake × 100). We performed bivariate analyses (Spearman’s correlation) and multiple linear regression adjusted for potential confounders, considering p < 0.05 as significant.

Results

The median PI was 9.80 (interquartile range: 11.45). PI was inversely correlated with BMI (rs: −0.43) and WC (rs: −0.36) and positively correlated with high-density lipoprotein cholesterol (HDL-cholesterol) (rs: 0.25), all with p < 0.05. In multiple regression analysis, PI was inversely associated with BMI (B: −0.08; 95%CI: −0.15, −0.01) after adjusting for total energy, sex, age, and physical activity; and positively associated with HDL-cholesterol (Model 1 adjusted for total energy, sex, age, and physical activity [B: 0.21; 95% CI: 0.02, 0.41]; Model 2 adjusted for BMI, sex, age, and physical activity [B: 0.21; 95% CI: 0.008, 0.40]; Model 3 adjusted for WC, sex, age, and physical activity [B: 0.20; 95%CI: 0.01, 0.40]), all with p < 0.05.

Conclusion

The results have demonstrated that higher phytochemical intake, expressed by PI, was inversely associated with BMI and positively associated with HDL-cholesterol.

Epidemiological Profile: An Important Step in the Organization of Medical Care

Ana Paula Damiano

The demographic-epidemiological study of a disease allows for a more accurate characterization of situations involving the care of this pathology and a better distribution of resources, often scarce, thereby optimizing patient care. In a scenario of general lack of financial, technological, and professional resources, it is necessary to develop a program that addresses all processes, streamlining the care network flow and,m consequently, that produces a positive impact on the outcome. Continuous reassessment of methods and criteria are necessary in order to evaluate the need for the reorganization and redirection of resources.

When treating congenital heart disease (CHD), the estimated prevalence may seem insignificant, when compared to other more prevalent cardiac pathologies, such as coronary artery disease. In Brazil, a prevalence of 12:1,000 live births with CHD has been estimated, corresponding to 25,757 new cases per year. These were responsible for 6% of all deaths in children < 1 year of age, according to data from Pinto Jr., Salim et al., observed that the main cause of death in young people under 20 years of age between 2000 and 2015 was circulatory system malformation. The clinical presentation of diseases is extremely variable, with symptoms that can start from the fetal period to adulthood and the correct diagnosis at an appropriate time is a determining factor for better therapeutic management and success. Lopes et al. demonstrated a lethality of 64.7% for critical CHD, which proved to be higher during the neonatal period. However, data on mortality must be interpreted in the context of available medical care in the studied region.

Weight Excess: The Great Villain in the Development of Hypertension in Adolescents

Erika Maria Gonçalves Campana et al. Maria Eliane Campos Magalhães Andréa Araujo Brandão

The relationship between arterial hypertension (AH) and excess weight in young populations is well established. This association involves several conditions including hyperinsulinemia, altered adipokine profile, elevated markers of subclinical inflammation, and inadequate habits, including physical inactivity.^–

In a study^– conducted in the city of Rio de Janeiro, Brazil, an increased body mass index in adolescents was correlated with a higher prevalence of elevated blood pressure (BP) and higher risk of developing AH at young adult age. From a longitudinal perspective, an interesting aspect in the assessment of cardiovascular risk factors is the tracking effect, in which children and adolescents with altered clinical and metabolic parameters (BP, body mass index and cholesterol levels) are likely to maintain an abnormal profile of these variables throughout life and become adults at increased cardiovascular risk.^– This fact highlights the continuous, unfavorable impact of persistent obesity from childhood to adulthood on cardiovascular risk factors.

Sex and Gender Equity in Research and Publishing: International Journal of Cardiovascular Sciences endorses SAGER Guidelines

Claudio Tinoco Mesquita et al. Aline Goneli de Lacerda

According to the recently published “Cardiovascular Statistics – Brazil 2020”, mortality from cardiovascular diseases (CVD) is proportionally higher in women compared to men. The INTERHEART study demonstrated that the population attributable risk for myocardial infarction associated with modifiable risk factors of smoking, alcohol use, high-risk diet, and physical inactivity, was significantly higher among women than men. Evidence from the VIRGO study (Variation in Recovery: Role of Gender on Outcomes of Young Acute Myocardial Infarction [AMI] Patients) indicates that both health professionals and women are unaware or neglect the development of cardiovascular heart disease (CHD) and the presence of cardiovascular risk factors in women.

Women are underrepresented in cardiovascular disease trials despite known sex differences across a broad range of risk, prevention, treatment, and outcome parameters. Gender influences many aspects of disease like its pathophysiology and clinical presentation, response to treatment, clinicians’ behavior, and access to health care,^, and now it is clear that research must consider this to promote better diagnosis and treatment, and gender equity in health care.

Diet Quality and Associated Factors in Atherosclerotic Cardiovascular Disease Patients with and without Diabetes at a Specialized Outpatient Clinic in the City of Pelotas, Brazil

Fernanda Vighi Dobke et al. Aline Longo Bruna Luiza Paulina Ribas Bernardete Weber … Eduardo Gehling Bertoldi Lúcia Rota Borges Renata Torres Abib Bertacco

Abstract

Background

In most cases, atherosclerotic cardiovascular disease (ACVD) is preventable through primary prevention and control of traditional risk factors, such as smoking cessation, regular physical activity, and adherence to healthy dietary patterns. The assessment of diet quality of ACVD patients would be important for a dietary intervention.

Objectives

This study aimed to evaluate diet quality of ACVD patients and its association with clinical conditions.

Methods

This cross-sectional study was nested within a randomized clinical trial entitled “Programa Alimentar Cardioprotetor Brasileiro.” Baseline data of 80 patients from Pelotas, Brazil, were obtained. Food consumption was assessed using 24-h food recall and the Revised Diet Quality Index (IQD-R). Data on smoking status and comorbidities were reported by the patients during medical history taking. To analyze the associations between IQD-R and clinical variables, unpaired Student’s t-test or the analysis of variance was performed. The significance level was 5%.

Results

Most of the sample consisted of men (66.5%), elderly individuals (52.50%), patients with hypertension (78.75%), dyslipidemia (58.75%), and overweight (73.75%). The average IQD-R score was 56.7 ± 12.6 points. Better quality of diet was observed for patients with diabetes compared to those without diabetes (61.1 ± 11.8 versus 54.0 ± 12.6 points; p=0.014).

Conclusion

There is a need to improve diet quality of ACVD patients. Patients ACVD and diabetes had better diet quality compared to those without diabetes.

The Role of Pharmacists in Antihypertensive Pharmacotherapy

Christianne Bretas Vieira Scaramello et al. Flavia Valeria dos Santos Almeida

Hypertension encompasses a preventable risk factor associated with a significant global burden of cardiovascular disease (CVD) and premature death. Its prevalence is rising worldwide due to population aging, unbalanced diets, and sedentary, especially in low- and middle-income countries. Prevalence data in Brazil vary according to the database. However, about 30% of adults present blood pressure of 140/90 mmHg or more, with CVD representing 22.6% premature passing. This link between hypertension and CVDs-related deaths highlights the relevance of blood pressure control.

In 2021, the World Health Organization elaborated evidence-based guidance for the pharmacological treatment of nonpregnant adults with an accurate diagnosis of hypertension who have already received counseling for lifestyle modification. It is crucial to set blood pressure threshold to pharmacological therapy beginning and treatment targets. In addition, the determination of follow-up visits to adjust monotherapy or dual therapy embracing single or dual pill combination medications is mandatory. Comorbidities, unwanted effects, cost, and acceptability must also be evaluated. In 2020, the Brazilian Society of Cardiology also published decision and therapeutic goals for hypertension management.

HDL-Cholesterol in Children and Adolescents with Congenital Heart Disease

Matheus Alves Pacheco et al. Silvia Meyer Cardoso Michele Honicky Yara Maria Franco Moreno … Luiz Rodrigo Augustemak de Lima Camila Souza Marcos Isabela de Carlos Back

Abstract

Background

Children and adolescents with congenital heart disease may be more likely to develop atherogenic cardiovascular diseases in adulthood. Therefore, the early identification of risk factors and intervention in childhood may be crucial for a good quality of life and longevity.

Objectives

To describe the distribution of high-density lipoprotein-cholesterol (HDL-c) levels and its association with socioeconomic, clinical and cardiovascular risk factors in children and adolescents with congenital heart disease.

Methods

Cross-sectional study with children and adolescents aged between 5 and 18 years, with congenital heart disease. Socioeconomic, clinical and cardiovascular risk factors were evaluated. HDL-c concentrations were evaluated by the direct method and categorized as desirable (>45 mg/dL), borderline (40-45 mg/dL) and low (<40 mg/dL). We also assessed the “undesirable” levels, consisting of the sum of “borderline” and “low” values for comparative purposes. The multivariate logistic regression analysis was used to evaluate the factor associated with undesirable HDL-c levels. A p<0.05 value was adopted as statistically significant.

Results

Mean HDL-c was 51.2 mg/dL (SD 12.6), with a prevalence of 33.2% of undesirable HDL-c. In the multivariate analysis, C-reactive protein levels ≥ 3mg/dL (OR 3.26; 95% CI 1.32-8.04), age ≥ 10 years old (OR: 2.11; 95% CI 1.12-3.99) and undesirable levels of triglycerides (OR 2.21; 95% CI 1.13-4.75) were associated with undesirable HDL-c.

Conclusion

In this sample of children and adolescents with congenital heart disease, almost one third presented low or borderline HDL-c levels. Age ≥10 years, C-reactive protein and triglycerides were associated with undesirable HDL-c levels. These factors should be considered in the prevention of cerebrovascular diseases in adulthood in this population.

Is Patient Education about the Benefits of Physical Activity a Good Adjunct Treatment Strategy in Hypertension?

Dário C. Sobral Filho et al. Maria de Fátima Monteiro

Systemic arterial hypertension (SAH) is a chronic condition that is highly prevalent worldwide. It occurs without symptoms in most individuals and represents the main modifiable risk factor for cardiovascular disease. The adoption of behaviors that do not involve medication, such as changes in lifestyle and regular practice of physical exercise, along with strict adherence to prescribed medication, is a major challenge in the treatment of this disorder.^,

The guidelines of the American Heart Association and the American College of Cardiology on hypertension recommend the implementation of lifestyle changes as the first line of treatment for low- to moderate-risk groups, thereby emphasizing the importance of such measures.

Cardiovascular Risk Factors in Children and Adolescents with Fontan Circulation

Sandra Mari Barbiero et al. Rafael B. Carloto Danielly Steffen Pereira Gabriela C. Schwantes … Marcela Menuci Guimarães Maíra Ribas Goulart Daniela Schneid Schuh Lucia Campos Pellanda

Abstract

Background:

Long-term outcomes of patients with Fontan circulation are uncertain regarding the prevalence and role of risk factors (RFs) such as increased body mass index (BMI), arterial hypertension, and hypercholesterolemia.

Objectives:

To describe the prevalence of RFs in patients with univentricular heart, with variable follow-up times.

Methods:

This mixed cohort study was performed with 66 patients, who underwent blood count, fasting blood glucose, C-reactive protein (CRP), and lipid profile tests; systolic/diastolic blood pressure (SBP/DBP) measurements; and anthropometric and sociodemographic data collection. Cardiovascular RFs among first-degree relatives and physical activity habits were also assessed. Prevalence was described using proportions, with a 95% confidence interval. Continuous variables (height, weight, age, SBP, DBP) were described as means and standard deviations (m±SD). Associations between RFs were assessed using chi-squared or Fisher’s exact tests. Spearman’s correlation was used for analyzing CRP and the presence of 2 or more RFs. The Shapiro-Wilk test was used to check for data normality. Statistical significance considered p<0.05.

Results:

In our population, 19.7% were overweight, mean SBP was 89.44±37.4, and mean DBP was 60.0±26.08. The most prevalent diseases in the interviewees’ families were systemic arterial hypertension (30.3%), obesity (16.7%), and 2 or more cardiovascular RFs among first-degree relatives (13.8%). We observed a trend towards significance between the presence of 2 familial RFs and overweight, as well as a risk profile for cardiovascular disease. There was an association between the BMI percentile, the presence of 2 or more RFs (p<0.05), and CRP (p<0.01).

Conclusions:

Overweight is common in patients with univentricular heart, being related to more than 2 cardiovascular RFs among first-degree relatives; physical inactivity and changes in lipid profiles are also frequent.
