Abstract Background Exercise training programs improve exercise capacity and quality of life (QoL) in patients with coronary artery disease (CAD). Although artificial intelligence (AI) has been used to design such programs, there are still few studies evaluating their effectiveness. Objectives This study compared the effects of technology-based and traditional programs for cardiac rehabilitation (CR) on exercise capacity and participation in patients with CAD using AI for data analysis. Methods A total of 52 patients with CAD were randomly assigned to […]

Abstract Background Risk stratification in chronic coronary syndrome (CCS) patients is challenging. TIMI Risk Score for Secondary Prevention (TRS2P) is a simple nine-point tool developed to predict cardiovascular death, myocardial infarction (MI), and ischemic stroke among post-MI patients. No studies have been conducted on it in the Brazilian population. Objective Validate the TRS2P score among CCS patients at a tertiary center in Brazil. Methods This is a registry-based study of patients with CCS, defined as having a previous revascularization procedure, […]

Abstract Background In the assessment of ischemic heart disease, cardiac magnetic resonance (CMR) is considered the gold standard for detecting and locating myocardial infarction (MI), but electrocardiogram (ECG) is less expensive and more widely available. Recognition of MI on ECG outside the acute phase is challenging; Q waves are absent in a significant proportion of patients and may reduce or disappear over time. Although ECG is widely used in the initial assessment of previous infarction, studies to validate ECG using […]

Abstract Background Reducing hospital readmissions following coronary artery bypass grafting (CABG) surgeries is essential to optimizing medium- and long-term patient outcomes. Objective To analyze preoperative predictors associated with all-cause and cardiac readmissions within 5 years following CABG. Methods We analyzed 1,387 patients who underwent CABG between June 2017 and July 2019 using data from the multicenter REPLICCAR II registry. Follow-up was carried out by telephone interviews using a questionnaire structured in the REDCap platform. Statistical analysis included univariate and multivariate […]

Abstract Background Previous studies have shown that women with coronary artery disease (CAD) are less likely to undergo angiography and have less favorable outcomes after percutaneous coronary intervention (PCI). Objectives Assess the outcomes of women with acute coronary syndrome (ACS) and stable CAD (lesion>50%) treated with contemporary PCI using DES. Methods Observational, longitudinal cohort study with prospective follow-up included all female patients ≥ 18 years admitted at a tertiary public cardiovascular center in Brazil from January 2019 to December 2020. […]

Introduction Laughter therapy, also known as humor therapy, utilizes laughter and enjoyment as tools to enhance physical and emotional well-being. This practice offers numerous benefits, including: (1) lowering cortisol levels, thereby reducing stress – a well-established cardiovascular risk factor; (2) improving blood circulation through the release of vasoactive substances; and (3) boosting mood, which helps to combat depression and anxiety – conditions commonly found in patients with cardiovascular diseases and which are also risk factors for the development of coronary […]

Abstract Despite significant advances in the management of coronary artery disease (CAD) and reductions in annual mortality rates in recent decades, this disease remains the leading cause of death worldwide. Consequently, there is an ongoing need for efforts to address this situation. Current clinical algorithms to identify at-risk patients are particularly inaccurate in moderate-risk individuals. For this reason, the need for ancillary tests has been suggested, including predictive genetic screening. As genetic studies rapidly expand and genomic data becomes more […]

Abstract Background Women, in comparison to men, experience worse outcomes after acute coronary syndrome (ACS). However, whether the female sex per se is an independent predictor of such adverse events remains unclear. Objective This study aims to assess the association between the female sex and in-hospital mortality after ST-elevation myocardial infarction (STEMI). Methods We conducted a retrospective cohort study by enrolling consecutive STEMI patients admitted to a tertiary hospital from January 2018 to February 2019. All patients were treated per […]
