Demographic and clinical characteristics of pulmonary arterial hypertension caused by schistosomiasis are indistinguishable from other etiologies.

Introduction: Pulmonary arterial hypertension (PAH) is a serious pulmonary circulation disease caused by several etiologies, including schistosomiasis. The present study retrospectively evaluated the clinical and hemodynamic characteristics of patients with schistosomal PAH (PAH-Sch) compared to those of non-Sch PAH patients (non-Sch PAH).

Methods: Patients treated at the Pronto-Socorro Cardiológico de Pernambuco and diagnosed by right cardiac catheterization were divided into PAH-Sch and non-Sch PAH groups.

Polymorphisms of and genes related to time in therapeutic range in patients with atrial fibrillation using warfarin.

Introduction: Warfarin continues to be the most widely used anticoagulant in clinical practice around the world for the prevention of thromboembolic events in patients with atrial fibrillation (AF). The evaluation of the quality of anticoagulation control, estimated by time in therapeutic range (TTR), is accepted as a good method to evaluate the quality of anticoagulation. The variability of TTR can be explained by the presence of variants of the and genes.

Expression of microRNAs (133b and 138) and Correlation with Echocardiographic Parameters in Patients with Alcoholic Cardiomyopathy.

Introduction: Alcoholic Cardiomyopathy (ACM) is a disease with a difficult diagnosis. The real mechanisms related to its pathophysiology are not fully understood.

Objective: The aims of this study were to investigate whether miR-133b and miR-138 could be associated with ACM.
