The Brazilian Society of Cardiology’s most traditional scientific journal, with 73 years of history, Arquivos Brasileiros de Cardiologia or ABC Cardiol, has recently reached a new level of international recognition based on its 2020 impact factor, which is a new historical record. ABC Cardiol‘s new impact factor is 2.0, as published by the 2020 Journal of Citation Report (JCR, Clarivate), which means that, on average, each article published in ABC Cardiol was cited 2 times by other articles. This represents […]

Abstract Background: Statin use is highlighted as the most commonly utilized therapy for the treatment of dyslipidemias and can be considered as the most efficient pharmacological intervention for low-density lipoprotein (LDL) reduction. On the other hand, physical training can be considered an efficient and safe non-pharmacological strategy to promote improvements in lipid profile. However, the influence of statins on lipid adaptations arising from water-based training in populations with dyslipidemia is not known. Objectives: To analyze the influence of simvastatin use […]

Abstract Background: GRACE, TIMI and HEART scores have been previously validated to predict serious untoward events among patients with non-ST elevation acute coronary syndrome (Non-ST ACS). However, the ability of these scores to discriminate the angiographic complexity of coronary artery disease has not been clearly established. Objectives: We sought to evaluate the correlation between clinical scores (TIMI, GRACE and HEART) and the anatomical complexity assessed by SYNTAX score, among non-ST ACS patients undergoing cinecoronariography. Methods: Transversal cohort encompassing patients with […]

Abstract Background: Nucleus tractus solitarius (NTS) is a brain area that plays a key role in kidney and cardiovascular regulation via baroreceptors impulses. Objectives: The aim of this study was to evaluate the effect of naringin (NAR) and trimetazidine (TMZ) alone and their combination on NTS electrical activity and baroreceptor sensitivity (BRS) in renal ischemia- reperfusion (I/R) injury. Methods: Forty male Sprague-Dawley rats (200- 250 g) were allocated into 5 groups with 8 in each. 1) Sham; 2) I/R; 3) […]

Abstract Background: The classification of heart failure (HF) by phenotypes has a great relevance in clinical practice. Objective: The study aimed to analyze the prevalence, clinical characteristics, and outcomes between HF phenotypes in the primary care setting. Methods: This is an analysis of a cohort study including 560 individuals, aged ≥ 45 years, who were randomly selected in a primary care program. All participants underwent clinical evaluations, b-type natriuretic peptide (BNP) measurements, electrocardiogram, and echocardiography in a single day. HF […]

Abstract Background: Although maximal and submaximal walking are recommended for patients with peripheral artery disease (PAD), performing these exercises may induce different physiological responses. Objectives: To compare the acute effects of maximal and submaximal walking on post-exercise cardiovascular function, regulation, and associated pathophysiological processes in patients with symptomatic PAD. Methods: Thirty male patients underwent 2 sessions: maximal walking (Gardner’s protocol) and submaximal walking (15 bouts of 2 minutes of walking separated by 2 minutes of upright rest). In each session, […]

Abstract Background: Acute myocardial infarction (AMI) is the main cause of death in Brazil and the world. Approximately half of these deaths occur outside the hospital. Objectives: To analyze the distribution, temporal evolution, and sociodemographic characteristics (SDC) of in- and out-of-hospital deaths by AMI in Brazilian state capitals and their relationship with municipal development indicators (MDI). Methods: This is an ecological study of the number of deaths due to AMI reported annually by the 27 Brazilian state capitals from 2007 […]

Abstract Background: Cardiovascular diseases (CVD) and cancer are the main causes of death worldwide. These diseases share many risk factors. Control of traditional risk factors for CVD was associated with lower incidence of cancers. Objective: To analyze CVD and cancer mortality rate trends in Brazilian population aged 35-74 years from 1996 to 2017. Methods: Crude and age-adjusted death rate trends were analyzed for all causes of death, CVD, and cancer. Data were obtained from mortality database of the Ministry of […]

Abstract Background: Brugada Syndrome is an inherited arrhythmogenic disorder characterized by the presence of specific electrocardiographic features with or without clinical symptoms. The patients present increased risk of sudden death due to ventricular fibrillation. The prevalence of this electrocardiographic pattern differs according to the studied region. However, epidemiological information including the Brazilian population is scarce. Objectives: To assess the prevalence of the electrocardiographic pattern of Brugada syndrome and the epidemiological profile associated with it. Methods: Cross-sectional study that included 846,533 […]

Abstract Background: The interruption of the time spent in sedentary behavior (breaks) has been associated with better levels of cardiometabolic indicators in the adult population, but in adolescents, further investigations are still needed to confirm these findings. Objectives: To analyze the association of the number of breaks per day in sedentary behaviors with cardiometabolic markers and whether it was moderated by nutritional status and excessive time on sedentary behavior in adolescents. Methods: This is a cross-sectional study of 537 adolescents […]

Abstract Background Patients with HIV are more likely to present with cardiovascular disease when compared to the general population. Objective This was a case-control study that aimed to assess which factors were associated with a reduction in the carotid intima-media thickness (IMT) and an increase in the brachial artery flow-mediated dilation (FMD) in HIV patients who received atorvastatin + aspirin during a period of 6 months. Methods A secondary analysis of a clinical trial was conducted, which included people living […]

Abstract Background: Hyperuricemia is a frequent finding in patients with arterial hypertension, and there is increasing evidence that this entity is also a risk factor for cardiovascular disease. Objective: In the context of an aging population, this study aims to evaluate serum uric acid levels and arterial hypertension prevalence and control in a subgroup of Romanian adults (>65 years), concerning the influence of age on these parameters. Method: The study sample consists of 1,920 adults included in SEPHAR III survey, […]

Abstract Background: Type 1 cardiorenal syndrome is associated with higher mortality in heart failure patients. However, few studies have compared the diagnostic criteria of acute kidney injury (AKI) in this population. Objective: To assess clinical and functional features and factors associated AKI in patients with heart failure. Method: Retrospective, cohort study on patients with decompensated heart failure or recent acute myocardial infarction, conducted in a tertiary hospital in a low-income region of Brazil. Clinical, laboratory and echocardiographic features were compared […]

Abstract Since December 2019 we have observed the rapid advance of the severe acute respiratory syndrome caused by the new coronavirus (SARS-CoV-2). The impact of the clinical course of a respiratory infection is little known in patients with hereditary arrhythmias, due to the low prevalence of these diseases. Patients who present with infectious conditions may exacerbate hidden or well-controlled primary arrhythmias, due to several factors, such as fever, electrolyte disturbances, drug interactions, adrenergic stress and, eventually, the septic patient’s own […]

Introduction Transcatheter aortic valve implantation (TAVI) is a well-established procedure in reference centers worldwide and is currently accepted as the method of choice in high- and intermediate-risk patients. Although unusual, catastrophic complications can occur before or after its implantation, such as coronary obstruction, rupture of the aortic valve annulus, cardiac tamponade, significant perivalvular insufficiency and prosthesis embolization/displacement. Data from a recently published North American registry showed that 1,695 patients (2.8%) undergoing TAVI required some type of mechanical circulatory support during […]

Introduction Hyperlipidemia can increase morbidity and mortality. This condition has been classified by Fredrickson into the following phenotypes: I, IIa, IIb, III, IV and V.– In the mixed ones, the following conditions are present: hypercholesterolemia and hypertriglyceridemia, phenotypes IIb and III, with cholesterolemia and triglyceridemia of 250 to 300 mg/dL in phenotype IIb, and 500 to 600 mg/dL or more, in III, respectively. Pancreatitis is uncommon in both, as well as xanthomatosis in IIb. Xanthomas and cardiovascular complications are more […]

Introduction Throughout the SARS-CoV-2 pandemic, there have been reports of infection leading to acute myocardial injury, causing worse clinical outcomes. The manifestations can include troponin elevation, imaging exam abnormalities and electrocardiographic changes. Accordingly, ST-segment elevation (STE) acute myocardial injury has been observed in some patients. However, despite the electrocardiogram (ECG) ischemic changes, complementary exams may not show any obstruction, excluding coronary occlusion as the cause of the injury. […]

Dear Editor, We would like to share ideas on the publication “Cardiovascular Imaging in Patients with COVID-19.” Grossman and Lima concluded that “nuclear cardiologists and nuclear medicine physicians must be aware of incidental findings in asymptomatic patients with COVID-19, and they should optimize MPI protocols, when the procedure is necessary.” The results in this study are concordant with a previous report from Asia. Imaging can help identify both heart and lung problems that might asymptomatically occur due to COVID-19 or […]

Introduction In December 2019, health authorities in Hubei province, in the People’s Republic of China, identified and reported to the World Health Organization (WHO) an outbreak of pneumonia with an unknown etiological agent. In early January, the SARS-CoV-2 virus (Severe Acute Respiratory Syndrome Coronavirus 2) was identified and the disease was called COVID-19 (Coronavirus Disease 2019). On August 4, 2020, the disease has infected 18,316,072 people and caused the death of 694,715. The USA, Brazil and India occupy the first […]
