Abstract Background: Previous studies have observed a correlation between mortality rates from ischemic heart diseases (IHDs), cerebrovascular diseases (CBVDs), and the Social Vulnerability Index (SVI). However, doubts persist about the association between the overall SVI and its dimensions and mortality stratified by sex, ethnicity, and population clusters. Objective: To analyze the evolution of the overall SVI and its dimensions and correlate it with mortality rates due to IHD and CBVD in Brazil and its Federative Units (FUs) from 2000 to […]

Introduction Coronary fistulas (CFs) are defined as a direct anomalous connection between one or more coronary arteries with a large vessel or cardiac chamber. Most CFs drain into a lower pressure system, such as the right ventricle (RV) 40%, right atrium (RA) 26%, pulmonary artery (PA) 17%, coronary sinus 7%, and vena cava 1%. The clinical presentation will depend on the location and volume of the shunt generated by the fistula. Approximately 50% of cases are asymptomatic and, when present, […]

Abstract Background Acute coronary syndrome (ACS) is one of the leading causes of mortality worldwide. Knowing the predisposing factors is essential for preventing it. Objectives To describe the etiological and epidemiological characteristics of the population with ACS admitted to an emergency room in the State of São Paulo. Methods The prospective cohort study, based on electronic medical records from a public cardiology institute located in the state of São Paulo, Brazil, describes 5,580 patients hospitalized with ACS between August 2018 […]

Abstract Background Cell therapy using adipose-derived mesenchymal stem cells (ADSCs) shows great potential as a treatment for cardiovascular diseases. Objective We conducted a systematic review to describe the safety and efficacy of ADSCs in ischemic heart disease. Methods We searched PubMed/MEDLINE, EMBASE, Web of Science, CENTRAL, and LILACS (from inception to March 2024) for clinical studies involving ADSCs in patients with ischemic heart disease. We excluded studies involving patients with other types of heart disease, studies using mesenchymal stem cells […]

Abstract Background The association between exaggerated systolic blood pressure response to exercise (ESBPRE) and myocardial ischemia is controversial and little studied in patients with established or suspected chronic coronary syndrome. Objective To verify the relationship between myocardial ischemia and ESBPRE in patients undergoing exercise stress echocardiography (ESE). Methods This is a cross-sectional study with 14,367 patients undergoing ESE, from January 2000 to January 2022, divided into the following 2 groups: G1, composed of patients whose peak systolic pressure increased ≥ […]

Abstract Background Socioeconomic status has been linked to ischemic heart disease (IHD). High-income neighborhoods may expose individuals to a walking-promoting built environment for daily activities (walkability). Data from the association between income and IHD is lacking in middle-income countries. It is also uncertain whether walkability mediates this association. Objectives To investigate whether income is associated with IHD in a middle-income country and whether neighborhood walkability mediates the income-IHD association. Methods This cross-sectional study evaluated 44,589 patients referred for myocardial perfusion […]
