Abstract Background: Arrhythmias and Electrocardiography changes in Dengue Fever (DF) cases can mimic electrocardiogram (ECG) appearance of threatening clinical conditions such as myocardial ischemia, albeit no significant ischemic injury at the heart muscle. Case Presentation: We report a case of subsequent cardiac memory (CM) in a 50-year-old female with DF. A 12-lead ECG on admission revealed sinus rhythm with Left Bundle Branch Block (LBBB), and it resolved on day 4 of hospitalization. However, deep symmetric T wave inversions (TWI), which […]

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 […]

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 […]

Abstract Introduction: Cardiovascular diseases (CVDs) remain among the leading causes of morbidity and mortality worldwide, posing a significant public health challenge. Thus, analyzing their prevalence over time is crucial. Objective: To perform an epidemiological analysis of emergency hospital admissions due to CVD in Brazil between 2013 and 2023. Methods: This is an ecological, descriptive study based on data from the DATASUS database. Cardiovascular morbidities classified by ICD-10, along with variables such as sex and age group, were selected for analysis. […]

Abstract Background: Patients with chronic heart failure (HF) require outpatient monitoring after hospital discharge. The ability to use a smartphone with a personal messaging application may help. Objectives: Tis study aimed to investigate the feasibility of remote monitoring and evaluate its impact on treatment adherence and prognosis in patients with HF. Methods: A total of 100 patients were enrolled in the study: 57 patients in the mHealth group and 43 in the control group. The observation period lasted six months. […]

Abstract Spontaneous coronary artery dissection (SCAD) is a rare condition that can cause acute myocardial infarction (AMI), especially in young women without risk factors for coronary artery disease. Diagnosis is made by cardiac catheterization, and treatment varies from conservative to surgical approaches, depending on the severity. We report the case of a woman with a history of AMI who underwent initial catheterization without requiring percutaneous coronary intervention due to the absence of an obstructive lesion. Subsequently, the patient presented episodes […]

Abstract The authors describe a case of an infrequent triple association: left pulmonary artery aneurysm (PAA), uncorrected tetralogy of Fallot (TOF) and patent ductus arteriosus (PDA), diagnosed in a 45-year-old adult patient during a check-up. The patient refused to undergo surgery and is currently being followed clinically.

Abstract Background: Patients with chronic kidney disease (CKD) are at higher risk of cardiovascular disease. A dysfunctional autonomic nervous system may be the underlying cause. However, very few studies have determined the status of cardiac autonomic neuropathy (CAN) in both non-hemodialysis and hemodialysis CKD patients. Objectives: The present study intended to determine and compare CAN in both non-hemodialysis and hemodialysis CKD patients of primary renal diagnosis only and its correlation with the progression of the disease. Methods: Non-hemodialysis and hemodialysis […]

Abstract Background: Arterial hypertension (AH) is a significant risk factor for cardiovascular diseases (CVDs), including myocardial infarction and stroke. The ITGB3 gene polymorphism, particularly T1565C (rs5918), has been implicated in various cardiovascular conditions, suggesting a potential role in diastolic dysfunction (DD) among AH patients. Objectives: The clinical-genetic relationship was studied between ITGB3 gene polymorphisms and DD in Azerbaijani patients with AH, with or without ischemic heart disease (IHD) and type 2 diabetes (T2D) mellitus. Methods: The study included 100 Azerbaijani […]

Abstract Background: The impact of the COVID-19 pandemic on the healthcare of patients with ST-segment elevation acute myocardial infarction (STEMI) in Brazil remains unclear. Objective: Provide a descriptive analysis of clinical profiles, time intervals, performance metrics, and outcomes in patients with STEMI before and during the COVID-19 pandemic. Methods: Among a cohort of 193 patients with STEMI diagnosed in five emergency departments within a single Brazilian healthcare network, 187 patients were included between January 2017 and April 2021 and stratified […]
