A Fixed-Dose Triple-Combination Therapy for the Initial Steps of Hypertension Treatment: Protocol for the NEXT Randomized Clinical Trial

Rogerio Orlow et al. Caroline Consuelo de Sousa Sayuri Inuzuka Audes Feitosa … Andréa Araujo Brandão Marco Mota Gomes Vanildo da Silva Guimarães Neto Elizabeth do Espírito Santo Cestario Eduardo Costa Duarte Barbosa Rodrigo Bezerra Mayara Cedrim Santos Ana Luiza Lima Sousa Sandro Rodrigues Batista Priscila Valverde de Oliveira Vitorino Weimar Kunz Sebba Barroso

Introduction

Complications from arterial hypertension account for an estimated 18 deaths per minute worldwide, establishing it as the second leading risk factor for global mortality. Between 1990 and 2019, the number of adults with arterial hypertension doubled from 650 million to 1.3 billion. Of these, only 54% are diagnosed, 42% are treated, and a mere 21% of those treated achieve adequate blood pressure (BP) control.

Although effective BP control often requires the use of multiple drugs, monotherapy remains a predominant initial approach to arterial hypertension management globally, which limits the timely achievement of therapeutic goals. This is significant because even modest reductions in systolic BP of 5 mmHg are associated with an approximate 10% reduction in the risk of major cardiovascular events, irrespective of pre-existing cardiovascular disease.

Applicability of SAPS 3 and APACHE II Scores in a Cardiac Intensive Care Unit: A Prospective Study

Rafael Petri Pinheiro et al. Leonardo Castro Luna Vanessa dos Reis von Doellinger Marcelo Goulart Correia … Bernardo Tura Stephan Lachtermacher

Abstract

Background

Prognostic scores such as the Simplified Acute Physiology Score (SAPS) and the Acute Physiology and Chronic Health Evaluation (APACHE) are essential for assessing performance and predicting mortality in Intensive Care Units (ICUs).

Objectives

To evaluate the performance of SAPS 3 (including the Latin America [LA] and Brazil [BR] versions) and APACHE II in predicting mortality in a cardiac intensive care unit (CICU).

Methods

Prospective cohort of patients admitted between June 2022 and May 2024, followed until discharge or death. Data were extracted from electronic medical records. The relationship between observed and predicted mortality was calculated using the Standardized Mortality Ratio (SMR), and discrimination was assessed by the Receiver Operating Characteristic (ROC) curve.

Results

A total of 573 patients were included, 288 (50%) with three or more comorbidities, median age 63 years [IQR: 53–72], and 344 (60%) male. Cardiovascular diseases accounted for 76% of admissions. Overall mortality was 15%. Mean SMR values were: 0.52 (95% CI: 0.32–0.72) for SAPS 3; 0.40 (95% CI: 0.26–0.54) for SAPS 3 Latin America (AL); 0.79 (95% CI: 0.41–1.16) for SAPS 3 Brazil (BR); and 0.86 (95% CI: 0.42–1.29) for APACHE II. The analysis of the area under the curve (AUC) was 0.805 for SAPS 3 and its adapted versions, and 0.704 for APACHE II.

Conclusions

SAPS 3, particularly SAPS 3 Brazil (BR), demonstrated greater accuracy than APACHE II. Despite mortality being above the national average, the SMR indicated that observed mortality was lower than predicted, suggesting good care performance in the unit.

The Use of Simulation-Based Learning in Cardiology Education: A Systematic Review

André Luiz Lisboa Cordeiro et al. Washington Luiz Abreu de Jesus Tiago Veltri Osmastroni da Trindade Rodolfo Macedo Cruz Pimenta Rodolfo Prado da Silva

Abstract

The use of simulation in medical education is now a well-established practice. Many articles currently explore various simulation methods and the impacts reported by students. In cardiology, this is no exception; however, reviews on the topic do not focus on a specific area.

The objective of this study was to evaluate the existing evidence on the use of simulation in medical education, with a specific focus on cardiology.

This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched the Ovid MEDLINE, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS), CINAHL, and CENTRAL databases. Clinical trials reporting the use of realistic simulation for teaching cardiology were included. Two independent reviewers assessed the studies for eligibility. The simulation methods and topics, along with their evaluations, were analyzed.

A total of 435 articles were initially identified based on the search criteria. Seven articles were selected for detailed analysis. Three of these studies reported an improvement in cardiac auscultation skills through simulation. One study showed improved ability to recognize coronary anatomy; another demonstrated enhanced performance during catheterization, and one highlighted better outcomes during angioplasty. Only one study showed a slight improvement in the diagnosis of acute myocardial infarction. In addition to these clinical improvements, there was also a noted increase in student engagement and satisfaction.

Realistic simulation, when integrated as a complement to existing curricula, enhances the performance of cardiology students.

Left Versus Right Radial Access in Elderly Patients for Coronary Procedures: A Systematic Review and Meta-Analysis

Anna Loise da Cruz Gonçalves et al. Deivyd Vieira Silva Cavalcante Brenda de Adonai Rodrigues Martins Caroline de Oliveira Fischer Bacca … Júlia Gonçalves Gadelha Suelen Queiroz Gabriel Erzinger Octávio Drummond Guina

Abstract

Background:

Radial artery access is widely used in coronary procedures, but the optimal choice between left (LRA) and right (RRA) radial access remains controversial, especially in older patients.

Objective:

Compare LRA and RRA in patients ≥ 70 years undergoing coronary procedures.

Methods:

This study conducted a systematic review and meta-analysis of observational studies and randomized clinical trials (RCTs), adopting a significance level of 5% for all statistical analyses. We searched PubMed, Embase, and Cochrane Central for studies comparing LRA and RRA in patients aged ≥ 70 years. The main outcomes were fluoroscopy time, contrast volume, and procedure difficulty.

Results:

We included 1,094 patients from 4 studies, of which 3 were RCTs. Among them, 821 (75%) patients underwent the procedure via RRA. The LRA group showed a significantly shorter fluoroscopy time (standard mean difference [MD]: −0.41; 95% confidence interval [CI]: −0.67 to −0.42; p < 0.01; I² = 80%), and there was a significant reduction in the contrast volume between the groups, favoring LRA (MD: −13.04 milliliters; 95% CI: −18.0 to −8.20; p < 0.01; I² = 0%). However, there was no significant difference in the perceived difficulty level between the groups (risk ratio [RR]: 1.03; 95% CI: 0.61 to 1.73; p = 0.92; I² = 0%).

Conclusion:

LRA is associated with a significantly shorter fluoroscopy time, suggesting a greater efficiency in terms of radiation exposure. These findings imply that, while LRA may offer some efficiency benefits, the choice between LRA and RRA should consider other clinical and technical factors, such as operator preference and experience.

Performance Benchmarking of Open-Source Large Language Models on the Brazilian Society of Cardiology's Certification Exam

João Victor Bruneti Severino et al. Matheus Nespolo Berger Pedro Angelo Basei de Paula Filipe Silveira Loures … Solano Amadori Todeschini Eduardo Augusto Roeder Maria Han Veiga José Knopfholz Gustavo Lenci Marques

Abstract

Background:

Large language models (LLMs) have made a significant impact in medicine and demonstrate substantial promise for further development. However, most of the existing research has predominantly centered on English-language tasks with lower medical complexity. This underscores the importance of investigating the performance of state-of-the-art LLMs in more complex specialties, such as cardiology, and in languages beyond English, such as Portuguese.

Objective:

This study aimed to evaluate and compare leading LLMs based on their performance on the validated cardiology knowledge assessed by the Brazilian Society of Cardiology’s (SBC) Certification Exam.

Methods:

This study conducted a comparative analysis of 23 LLMs in the context of the SBC’s Certification Exam. The exam consists of 100 multiple-choice questions, 20 of which include images that cannot be processed by all LLMs. Therefore, these image-based questions were excluded from the analysis.

Results:

Proprietary LLMs showed a varying performance, with GPT-4o achieving the highest success rate at 62.25%, followed by Claude Opus at 60.25%. In the medium-sized model category (up to 100 billion parameters), Claude Haiku reached 47.25%. Among open-source models, Llama3 70B Instruct scored 53.50% in the large model category (over 100 billion parameters), while Llama3 8B achieved 36.25% in the small model category (under 20 billion parameters).

Conclusions:

Both proprietary and open-source LLMs underperformed on the test, failing to meet the exam’s cutoff score. Although larger models generally achieved better results, some medium-sized models — such as Llama3 70B Instruct and Claude Haiku—showed noteworthy results. The LLMs lacked specialized knowledge in cardiology and faced challenges in understanding Portuguese, revealing a significant gap in current AI capabilities and emphasizing the need for improvements.

Liza Yurie Teruya Uchimura et al. Cintia de Freitas Oliveira Mabel Fernandes Figueiró Camila Pereira Pinto Toth … Camila Roncon de Lima Patricia Vendramim

Abstract

Introduction

Cardiovascular diseases (CVD) are a major cause of mortality in Brazil, requiring the improvement of healthcare mechanisms that can promote rapid and effective care for patients.

Objectives

To identify and characterize Brazilian policies and programs (PP) regarding urgency and emergency care in the context of CVD.

Method

The scoping review followed recommendations from the Joanna Briggs Institute (JBI). The search for studies was conducted across seven databases. The screening and eligibility steps were performed by reviewers independently, with conflicts resolved by consensus or consultation with a third reviewer. The data extraction was done in a spreadsheet and the information was analyzed and grouped by content similarity.

Results

Through the analysis of 14 studies, a systematic and contextualized understanding was gained regarding 10 PPs implemented in the urgency and emergency network (RUE) for individuals with CVDs. SAMU emerged as the most extensively studied PP, predominantly in the state of Minas Gerais. The diseases most commonly addressed in these studies included acute myocardial infarction (featured in 80% of publications), stroke, acute coronary syndrome, heart failure, and atrial fibrillation. These PP have demonstrated significant improvements in clinical outcomes, particularly in reducing morbidity and mortality rates. The studies also revealed important insights into barriers and drivers related to infrastructure, health education, and system management and coordination.

Conclusion

The evidence gathered provides significant contributions to guide future policy development and improve decision-making in clinical management for cardiologists.

Computer-Interpreted Electrocardiograms: Impact on Cardiology Practice

Shyla Gupta et al. Anthony H. Kashou Robert Herman Stephen Smith … Adam May Ana G. Múnera Echeverri Mildren Del Sueldo Ana C. Berni Juan Farina Sebastian Garcia-Zamora Adrian Baranchuk

Abstract

In the realm of modern cardiology, the integration of computer-interpreted electrocardiograms (CI-ECGs) has marked the beginning of a new era of diagnostic precision and efficiency. Contemporary electrocardiogram (ECG) integration systems, applying algorithms and artificial intelligence, have modernized the interpretation of heart rhythms and cardiac morphology. Due to their ability to rapidly analyze and interpret ECG recordings CI-ECGs have already profoundly impacted clinical practice. This review explores the evolution of computer interpreted ECG technology, evaluates the pros and cons of current automatic reporting systems, analyzes the growing role of artificial intelligence on ECG interpretation technologies, and discusses emerging applications that may have transformative effects on patient outcomes. Emphasis is placed on the role of ECGs in the automatic diagnosis of occlusion myocardial infarctions (OMI). AI models enhance accuracy and efficiency in ECG interpretation, offering insights into cardiac function and aiding timely detection of concerning patterns for accurate clinical diagnoses. The shift to AI-driven diagnostics has emphasized the importance of data in the realm of cardiology by improving patient care. The integration of novel AI models in ECG analysis has created a promising future for ECG diagnostics through a synergistic fusion of feature-based machine learning models, deep learning approaches, and clinical acumen. Overall, CI-ECGs have transformed cardiology practice, offering rapid, accurate, and standardized analyses. These systems reduce interpretation time significantly, allowing for quick identification of abnormalities. However, sole reliance on automated interpretations may overlook nuanced findings, risking diagnostic errors. Therefore, a balanced approach in integrating automated analysis with clinical judgment is necessary.

The Old Problem of Adherence in the Control of Arterial Hypertension

Fernando Stuardo Wyss Quintana

In medical treatment of chronic diseases, for example, arterial hypertension, diabetes mellitus, and dyslipidemia, the main objective is the implementation of primary prevention or, failing that, secondary prevention of cardiovascular events, to achieve adequate control of cardiovascular prevention. Thus, the following measures are very necessary: 1. adequate patient education, 2. pharmacological prescription based on cardiovascular risk, and 3. adequate adherence to the prescribed treatment. This last point is, without a doubt, the most difficult to achieve.

The health interventions recommended by the World Health Organization for the control of these diseases focus on pharmacological treatments and general recommendations to take care of one’s diet and adopt healthy lifestyles, but the growth in prevalence shows that until now these treatments have been insufficient; that is, the therapeutic adherence of patients suffering from these diseases is low. This low adherence occurs because of personal therapeutic barriers and those of health systems.

Stress During ACLS Courses: Is it Important for Learning Skills?

Emilton Lima Júnior et al. José Knopfholz Carla M. Menini

OBJECTIVE: To determine the influence of stress on teaching medical emergencies in an Advanced Cardiac Life Support (ACLS) course and to verify this influence on learning, and the efficiency of emergency care training. METHODS: Seventeen physicians signed up for an ACLS course. Their pulses were taken and blood pressure (BP) verified on the first day, before the beginning of the course, and on the second day, during the theoretical and practical test (TPT). Variations in pulse rates and BP were compared with students’ test grades. Then, students answered a questionnaire of variables (QV) about the amount of sleep they had during the course, the quantity of study material and the time spent studying for the course, and a stress scale graphic. RESULTS: Seven students had a pulse variation less than 10% between the 2 periods and 10 had a 10% or more variation. Grades on TPT were, respectively, 91.4±2.4 and 87.3±5.2 (p<0.05). Six students had a BP variation less than 20 mmHg, and in 11 it varied more than 21 mmHg. Grades on the TPT were 92.3±3.3 and 86.2± 8.1, respectively (p<0.05). The QV dates did not significantly influence grades. CONCLUSION: Stress, as an isolated variable, had a negative influence on the learning process and on the efficiency of emergency training in this situation.

The Need for Pedagogical Qualifications for Teaching Cardiology to Undergraduate Students

Waldomiro Carlos Manfroi et al. Carmen Lúcia Bezerra Machado Ana Maria Petersen Maria Júlia P. Spina

OBJECTIVE: To report a training program in cardiology emphasizing changes in its pedagogical practice. These changes were put into practice by some teachers at the Medical School of Porto Alegre of the University of Rio Grande do Sul (FAMED/UFRGS) aiming to make faculty and student activities more dynamic and to promote more efficacious learning. The training program is directed at 5th semester medical students and aims at a behavioral change in teachers and students to promote more interaction, to favor exchanges, and to make the teaching-learning process easier, always maintaining the patient in the center of the medical activity. METHODS: The program emphasizes the definition of general and specific objectives for each activity to be developed by the students, with training in the area of admission to the cardiology service, with special emphasis on behavioral change in the cognitive, motor, affective, and attitudinal areas. Knowledge was developed by means of interactive seminars with initial and final assessment tests to identify students’ and teachers’ performance. The students were evaluated in an immediate, continuous, and progressive way in their daily activities and through comparison of the results of 2 tests, one applied at the beginning of the training and the other at its end. These 2 tests contained the same questions. RESULTS: We systematically assessed 560 students over 4 years. The mean grades of the tests performed prior to and after the 244 seminars were 7.38±1.66 and 9.17± 0.82, respectively (p<0.0001). For the tests applied at the beginning and at the end of the training, the mean grades were 5.61±1.61 and 9.37±0.90, respectively (p<0.0001). CONCLUSION: The program proved to be efficient both for the students' learning and for assessing their performance in a systematic and objective way.
