Background: Primary prevention of cardiovascular disease (CVD) remains a major challenge, especially in communities of low- and middle-income countries with poor medical assistance influenced by distinct local, financial, infrastructural, and resource-related factors.
Objective: This a community-based study aimed to determine the proportion and prevalence of uncontrolled cardiovascular risk factors (CRF) in Brazilian communities.
Methods: The EPICO study was an observational, cross-sectional, and community clinic-based study.
Background: Pharmacoinvasive strategy is an alternative when primary percutaneous coronary intervention (PCI) is not feasible.
Objectives: This study aimed to evaluate the effects of early pharmacoinvasive strategy on the infarct size and left ventricular ejection fraction in elderly and non-elderly patients. The role of inflammatory markers was also examined.
Background: Hypertrophic cardiomyopathy (HCM) can cause obstruction in the left ventricular outflow tract (LVOT), and be responsible for the onset of limiting symptoms, such as tiredness. When such symptoms are refractory to pharmacological treatment, interventionist alternative therapies can be useful, such as septal ablation through the infusion of alcohol in the coronary artery or through myectomy. Recently, the use of a radiofrequency (RF) catheter for endocardial septal ablation guided by electroanatomic mapping has proven to be efficient, despite the high incidence of complete atrioventricular block.

Despite early reperfusion, patients with ST segment elevation myocardial infarction (STEMI) may present large myocardial necrosis and significant impairment of ventricular function. The present study aimed to evaluate the role of subtypes of B lymphocytes and related cytokines in the infarcted mass and left ventricular ejection fraction obtained by cardiac magnetic resonance imaging performed after 30 days of STEMI. This prospective study included 120 subjects with STEMI submitted to pharmacoinvasive strategy.

Background: The effects of rivaroxaban in patients with atrial fibrillation and a bioprosthetic mitral valve remain uncertain.
Methods: In this randomized trial, we compared rivaroxaban (20 mg once daily) with dose-adjusted warfarin (target international normalized ratio, 2.0 to 3.

The efficacy and safety of rivaroxaban in patients with bioprosthetic mitral valves and atrial fibrillation or flutter remain uncertain. DESIGN: RIVER was an academic-led, multicenter, open-label, randomized, non-inferiority trial with blinded outcome adjudication that enrolled 1005 patients from 49 sites in Brazil. Patients with a bioprosthetic mitral valve and atrial fibrillation or flutter were randomly assigned (1:1) to rivaroxaban 20 mg once daily (15 mg in those with creatinine clearance <50 mL/min) or dose-adjusted warfarin (target international normalized ratio 2.

Objective: To investigate the behavior of circulating cytokines in patients with ST-segment elevation myocardial infarction (STEMI) and their relationship with ventricular function.
Methods: In the BATTLE-AMI (B and T Types of Lymphocytes Evaluation in Acute Myocardial Infarction) trial, patients with STEMI were treated with a pharmacoinvasive strategy.
Introduction: Atrial fibrillation (AF) is a growing public health problem especially due to its association with thromboembolic phenomena. Among its risk factors, obstructive sleep apnea (OSA) has increased in incidence and is often under diagnosed. OSA increases the risk of AF by mechanisms not fully known, but it may lead to remodeling and structural alteration of the atria.

Background: TAVR is an established treatment for aortic stenosis (AS). Few data exist on mid- to long-term outcomes and durability after new-generation valves.

Introduction: Few data exist regarding the late clinical impact of the Selvester score prediction of myocardial fibrosis after transcatheter aortic valve replacement (TAVR). This study evaluated the predictive power of the Selvester score on survival in patients with aortic stenosis (AS) undergoing TAVR.
Methods And Results: Patients with severe AS who had preoperative electrocardiograms were included.
Backgroud: The prevalence of obesity has systematically been increased in the population, including children and adolescents, around the world.
Objectives: To describe reference percentile curves for waist circumference (WC) in Brazilian children and provide cut-off values of WC to identify children at risk for obesity.
Methods: A multicenter, prospective, cross-sectional study was performed with children aged from 6 to 10 years old, enrolled in public and private elementary schools from 13 cities of the São Paulo State.

Objective: To investigate power of computed tomography venography (CTV) to identify and characterize iliac vein obstruction (IVO) compared with intravascular ultrasound (IVUS) examination in highly symptomatic patients with chronic venous disease (CVD).
Methods: CVD CEAP C3-6 limbs with visual analog scale for pain score of greater than 3 and/or Venous Clinical Severity Scale of greater than 8 were prospectively investigated with CTV and IVUS examination. The segment of maximum IVO was verified and categorically classified: group I, 0% to 49%; group II, 50% to 79%; and group III, 80% or greater.
Coronary computed tomography angiography (CCTA) has gained a prominent role in the evaluation of coronary artery disease. However, its anatomical nature does not allow the evaluation of the functional repercussion of coronary obstructions. It has been made possible to evaluate Myocardial computed tomography perfusion (Myocardial CTP) recently, based on myocardial contrast changes related to coronary stenoses.

Studies have demonstrated that a zero calcium score (CS) is characteristic of a low risk for cardiovascular events. However, the prevalence of individuals with coronary atherosclerotic plaques and zero CS is conflicting in the specialized literature.

Background: Early reperfusion of the occluded coronary artery during acute myocardial infarction is considered crucial for reduction of infarcted mass and recovery of ventricular function. Effective microcirculation and the balance between protective and harmful lymphocytes may have roles in reperfusion injury and may affect final ventricular remodeling.
Methods/design: BATTLE-AMI is an open-label, randomized trial comparing the effects of four therapeutic strategies (rosuvastatin/ticagrelor, rosuvastatin/clopidogrel, simvastatin plus ezetimibe/ticagrelor, or simvastatin plus ezetimibe/clopidogrel) on infarcted mass and left ventricular ejection fraction (LVEF) (blinded endpoints) in patients with ST-segment elevation myocardial infarction submitted to fibrinolytic therapy before coronary angiogram (pharmacoinvasive strategy).
Population assessment of effective blood pressure (BP) control is fundamental for reducing the global burden of hypertension, especially in low- and middle-income countries. The authors evaluated the effectiveness of BP control and determined independent predictors associated with effective control among patients with hypertension on drug treatment in a large cross-sectional study performed in two metropolitan areas in Brazil's southeast region. A total of 43 647 patients taking antihypertensive treatment were identified.

Cardiovascular diseases are the leading cause of mortality among women in several countries. Early detection of subclinical atherosclerosis (SA) could enable the adoption of preventive measures to avoid cardiovascular events. This study aimed to determine the prevalence of SA in Brazilian asymptomatic postmenopausal women in Framingham Risk Score (FRS) low and intermediate groups.

When injected into circulation, the LDE concentrates the carried drugs in neoplastic tissues and atherosclerotic lesions. In rabbits, atherosclerotic lesion size was reduced by 65% following LDE-paclitaxel treatment.
