Electrocardiographic findings and prognostic values in patients hospitalised with COVID-19 in the World Heart Federation Global Study.

Background: COVID-19 affects the cardiovascular system and ECG abnormalities may be associated with worse prognosis. We evaluated the prognostic value of ECG abnormalities in individuals with COVID-19.

Methods: Multicentre cohort study with adults hospitalised with COVID-19 from 40 hospitals across 23 countries.

Causality assessment of adverse drug reactions by applying a global introspection method in a high complexity hospital.

Background: Causality assessment of adverse drug reactions (ADRs) is an essential approach in pharmacovigilance. The World Health Organization-Uppsala Monitoring Center (WHO-UMC) system has been considered one of the most adequate method for establishing causal relationship in hospitalized patients.

Objective: To describe the causality of potential ADRs in hospitalized patients assessed by the WHO-UMC system and by different healthcare professionals.

The Burden of Resistant Hypertension Across the World.

Purpose Of Review: Resistant hypertension (R-HTN) is related to worse cardiovascular, renal outcomes, and death compared to non R-HTN. We aimed to review the burden of R-HTN across the world, focusing on its prevalence, associated factors and outcomes, and the impact of treatment.

Recent Findings: R-HTN prevalence among hypertensive individuals varies around 10-20%, depending on the population and definition applied.

Arrhythmias and electrocardiographic findings in Coronavirus disease 2019: A systematic review and meta-analysis.

Background: Coronavirus disease 2019 (COVID-19) primarily causes lung infection, but recent studies have shown that cardiac involvement is associated with a worse prognosis.

Objectives: We conducted a systematic review and meta-analysis to examine the prevalence of cardiac arrhythmias detected by the electrocardiogram and their relationships with adverse outcomes in patients with COVID-19.

Methods: PubMed and Google were searched for studies that reported on cardiac arrhythmias and/or examined the relationship between arrhythmias and adverse outcomes.

Prognostic value of electrocardiographic abnormalities in adults from the Brazilian longitudinal study of adults' health.

Objective: Cardiovascular diseases (CVDs) are highly preventable non-communicable diseases. ECG is a potential tool for risk stratification with respect to CVD. Our aim was to evaluate ECG's role in all-cause and cardiovascular mortality prediction.

Association between typical electrocardiographic abnormalities and NT-proBNP elevation in a large cohort of patients with Chagas disease from endemic area.

Chagas cardiomyopathy is the most harmful complication of Chagas disease. The electrocardiogram is a well-studied exam and has been considered an important tool for detection and evaluation of Chagas cardiomyopathy since the first years of its description. Many of its abnormalities have been described as associated with a worse prognosis.

Effects of exercise training on heart rate variability in Chagas heart disease.

Background: Heart rate variability (HRV) is a marker of autonomic dysfunction severity. The effects of physical training on HRV indexes in Chagas heart disease (CHD) are not well established.

Objective: To evaluate the changes in HRV indexes in response to physical training in CHD.

Tricuspid valve lesion due to penetrating chest trauma.

Tricuspid valve lesions caused by penetrating chest trauma are rare and often underdiagnosed. The objective of this report is to describe a case of severe tricuspid insufficiency secondary to a knifing incident with an insidious evolution, diagnosed 19 years after the incident. The case emphasizes the importance of adequate follow-up of patients that are victims of penetrating chest trauma for a long period after the injury, to detect possible late complications of the trauma.

Functional capacity and right ventricular function in patients with Chagas heart disease.

Aims: Right ventricular (RV) dysfunction is an important factor on effort tolerance in cardiopulmonary diseases. Nevertheless, the role of RV function in predicting exercise capacity in patients with Chagas disease has not been reported. This study aims to evaluate whether RV function assessed by tissue Doppler can predict functional capacity in patients with Chagas heart disease.

[Right-side infective endocarditis: discrepancy between clinical and echocardiographic evolution: case report].

Infective endocarditis is a relatively rare disease in clinical practice, with significant morbidity and mortality despite the improvements on its diagnosis and treatment. It is often difficult to identify its complications and define strategies for them. Dissociation between the clinical evolution and the findings from complementary tests (especially echocardiographic tests) is common.
