Cardiovascular Risk Stratification and Low-Density Lipoprotein Cholesterol Target Achievement in Primary Health Care: A Cross-Sectional Study

Gabriel Olivo Leandro et al. Pedro Henrique Daniel Abreu Samantha Cristiane Lopes Silvia Rozauria Froes Toniazzo

Abstract

Background:

Cardiovascular diseases (CVDs) remain the leading cause of mortality in Brazil. Effective dyslipidemia management is essential for preventing major adverse cardiovascular events (MACE); however, previous studies have reported low rates of lipid target achievement and inadequate statin prescribing in primary health care (PHC) settings.

Objective:

To evaluate low-density lipoprotein cholesterol (LDL-C) target achievement and the appropriateness of statin prescriptions according to cardiovascular risk among patients receiving PHC in a medium-sized Brazilian city.

Methods:

This cross-sectional study was conducted in 18 PHC units in Rio do Sul, Santa Catarina, Brazil, between January 13 and May 30, 2025. The study included 180 adults aged 30-59 years of both sexes who had been followed for at least 6 months and had a lipid profile assessment within the previous year. Cardiovascular risk was estimated using the Framingham Risk Score. Data were analyzed using the chi-square, Mann-Whitney, and Kruskal-Wallis tests. Statistical significance was set at p < 0.05.

Results:

Among the 180 participants, 95 (52.7%) did not achieve LDL-C targets. LDL-C goal attainment was more frequent among low-risk (85.7%) and intermediate-risk (23.9%) individuals and less frequent among high-risk (15.1%) and very high-risk (0.0%) individuals. Cardiovascular risk was significantly associated with lipid control (p < 0.05). Median LDL-C was 106.8 mg/dL (Interquartile Range (IQR), 88.4-136.2), with significant differences across risk categories (p < 0.05). Among the 56 statin prescriptions identified, only 26 (46.4%) were consistent with guideline-recommended statin intensity.

Conclusion:

The low rate of LDL-C target achievement and the high prevalence of inadequate statin therapy highlight the need for more effective lipid management strategies and structured interventions in PHC.

Daisy Motta-Santos et al. Thiago Barbabela de Castro Soares Maria Cecília Ramos de Carvalho Regina Márcia Faria de Moura … Sueli Ferreira da Fonseca Larissa Morelli Ferraz Guimarães Reginaldo Gonçalves Clara Rodrigues Alves de Oliveira Aline Cristine Souza Lopes Milena Soriano Marcolino

Abstract

Background:

Hypertension and Diabetes Mellitus (DM) are prevalent chronic conditions and major risk factors for cardiovascular diseases. Adequate control of these conditions is challenging, and lifestyle changes are crucial to achieving better management.

Objectives:

To evaluate the effectiveness of a multifaceted and multidisciplinary intervention to improve the control of hypertension and DM in the primary care setting.

Methods:

This cluster randomized clinical trial focuses on lifestyle modifications for managing hypertension and DM, addressing gaps in current non-pharmacological interventions. Primary care professionals are trained to promote health education on physical activity and nutrition. Support is provided through a telementoring program, including messaging app communication, biweekly online meetings (teletutoring), and asynchronous teleconsultations. Primary care professionals conduct twice-weekly group activities with structured intensity adjustments and biweekly health education sessions using interactive methods like conversations, games, and group dynamics. For patients unable to join group activities, brief counseling and guidance on unsupervised physical activity are offered.

Results:

The primary outcomes are blood pressure and glycated hemoglobin values. The innovative intervention program aims to empower primary care professionals and reduce barriers to care through lifestyle changes, improved health education, and support systems for both supervised and unsupervised interventions. Conclusions: Supporting primary care professionals through education and remote assistance can enhance the effectiveness of lifestyle interventions, contributing significantly to the control of hypertension and DM in primary care settings. Trial registration: Previously registered with .

Thiago Barbabela de Castro Soares et al. Priscila Lenita Candida dos Santos Regina Márcia Faria de Moura Daisy Motta-Santos … Reginaldo Gonçalves Polianna Delfino Pereira Daniella Nunes Pereira Clara Rodrigues Alves de Oliveira Lilian Cristina Rezende Aline Cristine Souza Lopes Milena Soriano Marcolino

Abstract

Background:

Cardiovascular diseases (CVD) are the leading cause of death worldwide, and behavioral changes are a cornerstone of their prevention and treatment. However, implementing such changes can be challenging, and the use of validated protocols may support this process.

Objectives:

To develop, implement, and evaluate a continuing education protocol for primary care professionals focused on creating and monitoring action plans for the care of patients with arterial hypertension (AH) and diabetes mellitus (DM).

Methods:

The strategy involved 20 hours of in-person workshops and 15 hours of online training, based on Ministry of Health guidelines and covering topics such as physical activity, nutrition, and lifestyle. Evaluation was conducted through the development of team-based action plans and the administration of a satisfaction questionnaire.

Results:

The model was implemented in five municipalities, with 166 healthcare professionals participating in the in-person workshops. All teams developed action plans to implement the covered topics within their local contexts. The workshops on physical activity, nutrition, and lifestyle change were mostly rated as “good,” “very good,” or “excellent.” The most frequently mentioned terms in the qualitative assessments were “content,” “knowledge,” and “practices.” The strategy proved feasible, and partnerships with local public institutions enabled the active involvement of health professionals in proposing solutions to identified issues ().

Conclusion:

The action plans were tailored to local realities and reflected a high level of satisfaction with both the content and the hands-on approach of the sessions.

Association Between Active Commuting and Cardiometabolic Diseases in Primary Health Care Users

Lucas Bressan Pes et al. Gustavo Olszanski Acrani Ivana Loraine Lindemann Shana Ginar da Silva

Abstract

Background

Although active commuting is inversely related to cardiovascular disease risk factors, these associations are unknown among Brazilian primary health care users.

Objective

To investigate the association between active commuting to daily activities and the prevalence of cardiometabolic diseases.

Methods

This cross-sectional study, conducted between May and August 2019, included primary health care users from all 34 primary health care centers in Passo Fundo, a city in southern Brazil. Cardiometabolic diseases (type 2 diabetes, hypertension, hypercholesterolemia, hypertriglyceridemia, cardiovascular diseases, and overweight/obesity) were measured by self-reported medical diagnosis using a questionnaire. Active commuting was analyzed dichotomously: daily commuting on foot or by bicycle was considered active, while daily commuting by car, motorcycle, or bus was considered passive. To determine the association between cardiometabolic diseases and active commuting, crude and adjusted prevalence ratios (PR) were estimated using Poisson regression, considering p <0.05 significant.

Results

The sample consisted of 1443 patients. There was an inverse association between active commuting and type 2 diabetes (PR: 0.59; 95% CI [Confidence Interval]: 0.39-0.90) and overweight/obesity (PR: 0.83: 95% CI: 0.71-0.98).

Conclusion

A lower prevalence of type 2 diabetes and obesity/overweight was observed in people who actively commute. These findings indicate that changes in urban infrastructure to enable safe active commuting will positively impact the health of the population.

Health Literacy, Patient Knowledge and Adherence to Oral Anticoagulation in Primary Care

Milena Soriano Marcolino et al. Thaís Lorenna Souza Sales João Antônio de Oliveira Danyelle Romana Alves Rios … Thaís Marques Pedroso Laura Caetano de Sá Maria Auxiliadora Martins Antonio Luiz Pinho Ribeiro

Abstract

Background

Warfarin is the only oral anticoagulant available in the Brazilian public health system. Health knowledge and treatment are essential to achieving the desirable therapeutic effect. However, data on these aspects among primary care patients are still lacking.

Objective

To assess health literacy, patient knowledge, and adherence to oral anticoagulation with warfarin, as well as the medication regimen complexity in primary health units in the municipality of Divinópolis, Minas Gerais, Brazil.

Methods

This cross-sectional study included patients using warfarin from primary care settings. Sociodemographic and clinical data were collected from medical records. Short Assessment of Health Literacy for Portuguese-Speaking Adults (SAHLPA-18), Oral Anticoagulation Knowledge (OAK), adaptation of the Measure of Adherence to Treatment (MAT-adapted) to oral anticoagulation, and Medication Regimen Complexity Index (MRCI) were applied, and the time in therapeutic range (TTR) was calculated. Patients were stratified in two groups (TTR < 60% and TTR ≥ 60%) and compared using Fisher's exact test at a significance level of p < 0.050.

Results

Analysis included 162 patients (64.8 ± 12.7 years old, 55.6% women). Nonvalvular atrial fibrillation (26.5%) and venous thromboembolism (24.1%) were the main indications for warfarin, and 67.9%, 88.3%, and 16.7% of the patients had inadequate health literacy, insufficient knowledge regarding anticoagulant therapy, and non-adherence to warfarin therapy, respectively. There was no significant association of these parameters in relation to TTR. MRCI showed high pharmacotherapy complexity between the drug prescriptions.

Conclusion

This study showed alarming insufficient knowledge about warfarin therapy and low health literacy in primary care patients.

Exercise-induced Bronchoconstriction and its Relevance in Public Health

Tales de Carvalho

The case report from Castro et al., entitles Exercise-Induced Bronchoconstriction: A Frequent, but Neglected Cause of Chest Pain, opportunely sheds light on a highly relevant question in terms of public health, as it treats important aspects that encompass from the diagnosis to the pharmacological treatment of Exercise-Induced Bronchoconstriction (EIB).^–

EIB often leads to an isolated cough, as well as thoracic and abdominal pain, which should always be contemplated after having discarded other causes of dyspnea and exercise-induced chest pain.^– It is an acute airway obstruction that is transitory and spontaneously reversible, and occurs during and after exercise and physical effort, regardless of the previous diagnosis of bronchial asthma. EIB normally arises 2 to 5 min after exercise, reaching a peak at 10 min and disappearing in up to 60 min.^,,

Optimal Cutoff of the TG/HDL-c ratio for Cardiovascular Risk in Hypertensive and Diabetic Patients Monitored by Primary Health Care in a city in Minas Gerais

Eunice Ferreira da Silva et al. Rosângela Minardi Mitre Cotta Érica Toledo Mendonça Deíse Moura de Oliveira … Silvia Almeida Cardoso Renata Maria Colodette Tiago Ricardo Moreira

Abstract

Background

The analysis of the atherogenic potential of the lipid profile for biomarkers, such as the TG/HDL-c ratio, predicts cardiovascular risk better than isolated lipids.

Objective

To identify the TG/HDL-c cutoff points for multiple risks (hypertension, Diabetes Mellitus, obesity) and to evaluate the association between sociodemographic, clinical, laboratory, anthropometric, and life habit variables and the TG/HDL-c ratio in hypertensive and/or diabetic individuals in the context of Primary Health Care.

Methods

This was a cross-sectional study with 833 hypertensive and/or diabetic patients, conducted between August 2017 and April 2018. The cutoff point of the TG/HDL-c were obtained by the ROC curve. Cardiovascular risk was discriminated by TG/HDL-c, categorized by the cutoff and evaluated in relation to multiple risks. The magnitude of the association between TG/HDL-c and independent variables was estimated by logistic regression. The significance level of p<0.05 was adopted for all tests.

Results

The cutoff values of TG/HDL-c (3.26 for men and 2.72 for women) were more sensitive and less specific than those in the literature. Women (OR=1.90 and 95% CI 1.13-3.20) and men (OR=4.58 and 95% CI 1.78-11.76) with multiple risks, and white men, alcohol users, with a history of stroke, had a higher chance of altered GT/HDL-c. Increases in glycosylated hemoglobin, glycemia, and phosphorus in women, and cholesterol, glycemia, and microalbuminuria in men increased the chances of altered TG/HDL-c. Being a former smoker and black reduced the chance of altered TG/HDL-c in women.

Conclusions

TG/HDL-c proved to be a good indicator for habitual use in Primary Care.

Cardiovascular Risk Profile of a Young Adult Women Population Assisted in Primary Care

Tomás de Souza Mello et al. Mariana Stutz Klen Rafael Bellotti Azevedo Fernanda Costa Barradas … Luiza Araújo Nogueira Natália Rossilho Moyses Ushijima Rafael Barbosa da Silva Bica Elizabeth Silaid Muxfeldt

Abstract

Background

Although cardiovascular disease is a major cause of death among women, cardiovascular risk assessment in young women is frequently postponed due to a number of factors.

Objectives

To assess cardiovascular risk of young adult women living in one of Rio de Janeiro’s Family Health Strategy geographical units in the city’s central area.

Materials and Methods

populational, cross-sectional study with adults between 20 and 50 years old. Sociodemographic characteristics such as educational level and employment status were recorded. Anthropometric measurements, traditional cardiovascular risk factors, gynecological and gestational history, and selected laboratory exams were assessed. The bivariate analysis compared the baseline characteristics of the population between genders and the prevalence of cardiovascular risk factors in women according to educational level and occupation status, using non-paired Student’s t-test for normal continuous variables, Mann-Whitney test for asymmetrical continuous variables, and chi-square test for categorical variables. A significance level of 5% (p < 0.05) was adopted.

Results

A total of 710 individuals were enrolled. In women, who comprised 59.7% of our sample, central obesity and a sedentary lifestyle were more prevalent, whereas smoking and hypertension were less observed. However, women with lower educational status had a higher prevalence of smoking and hypertension. In hypertensive women, factors such as early menopause, higher prevalence of hypertensive disorders of pregnancy and higher number of pregnancies were noticed.

Conclusion

An adverse cardiovascular risk profile in our population of young women was particularly influenced by central obesity, sedentary lifestyle, hypertensive disorders of pregnancy and lower educational status.

Potential Impact of the New American High Blood Pressure Guidelines on Hypertension Prevalence in a Primary Health Care Unit in Rio de Janeiro – the LapARC Study

Marcelle Guimarães de Oliveira et al. Angélica Furriel de Almeida da Silva Taissa Lorena dos Santos Mariana Loureiro Cunha … Bruna Rosenbrock Ferreira Taveira Elizabeth Silaid Muxfeldt

Abstract

Background

The new American Heart Association guidelines for hypertension (HT) proposed a reduction of the diagnostic cut-off point, leading to a substantial increase in the prevalence of HT.

Objectives

To assess the prevalence of HT determined by the traditional criteria, the AHA criteria, and home blood pressure monitoring (HBPM) in a population of young adults attending a primary healthcare unit, and its association with cardiovascular risk.

Methods

A cross-sectional population study on adults aged from 20 to 50 years attending a primary healthcare unit, in Rio de Janeiro, Brazil. Sociodemographic and anthropometric data, cardiovascular risk factors, office blood pressure and HBPM were registered. The diagnosis of HT was defined by traditional criteria (office BP ≥ 140 x 90 mmHg) and by the new (AHA) criteria (office BP ≥ 130 x 80 mmHg). Bivariate analysis was used for comparisons between the two diagnostic criteria, and Kappa coefficient was used to assess the agreement in diagnosis between office BP and HBPM. The level of significance adopted was 5% (p<0.05).

Results

A total of 472 individuals were evaluated (male: 39%; mean age: 38.5 ± 8.7 years). The prevalence of HT was 23.5% and raised to 41.1% with the new AHA criteria. The prevalence of HT using HBPM was 25.5%, but the diagnostic agreement was low (kappa=0.028) with changes in diagnosis in 18% of the cases.

Conclusion

The prevalence of HT almost doubled with the new AHA diagnostic criteria for HT. HBPM seemed to be an important instrument in HT diagnosis in this population. (Int J Cardiovasc Sci. 2021; [online].ahead print, PP.0-0)

Increased Left Atrial Volume and Its Relationship to Vitamin D in Primary Care

Erica de Abreu Macedo et al. Maria Luiza Garcia Rosa Antônio José Lagoeiro Jorge Adson Renato Leite … Leivys Henrique Silva Santos Juliana Salge Vieira

Abstract

Background:

The study is based on the fact that left atrial (LA) volume measurement is a marker of the presence of diastolic dysfunction and that Vitamin D deficiency may be associated with ventricular remodeling, worsening of left ventricular (LV) diastolic and systolic function, and activation of the renin-angiotensin-aldosterone system.

Objective:

To evaluate whether LAV changes are related to vitamin D deficiency.

Method:

A cross-sectional, population-based, unicentric study in which 640 patients over 45 years of age enrolled in the Niterói’s Médico de Família program, RJ, were evaluated. Patients were submitted to tissue Doppler echocardiography to evaluate the parameters of diastolic and systolic function and vitamin D dosage. The presence or absence of hypovitaminosis D associated with structural and functional cardiac changes was compared between each group. A p < 0.05 value was considered as an indicator of statistical significance.

Results:

Of the 640 individuals analyzed, hypovitaminosis D was confirmed in 39.2% of the patients, of whom 34.8% had diastolic dysfunction. The most relevant echocardiographic parameters that were statistically significant were non-indexed AEDs and LAV, E’/A’ and E wave deceleration time, which were associated with the presence of hypovitaminosis D (P < 0.01).

Conclusion:

The study of the association of hypovitaminosis D and the appearance of structural and functional cardiac abnormalities may contribute to the discussion of the adoption of one more criterion to select individuals at risk of developing clinical cardiac insufficiency in primary care since, with the use of echocardiography, the subclinical condition of cardiac involvement, with prognostic and treatment implications for the referred patients with hypovitaminosis D, can be identified early.
