Vascular function after acute aerobic exercise in adults with and without type ...

It is unknown whether type 2 diabetes mellitus (T2DM) influences the vascular function response to aerobic exercise. We examined brachial artery flow-mediated dilation (FMD) and flow-mediated slowing (FMS) of pulse wave velocity (PWV), 10-and 60-min after a high-intensity interval exercise (HIIE) and moderate-intensity continuous exercise (MICE) in adults with and without T2DM. Twelve older male adults with T2D...

The contribution of genetics to the understanding and management of cardiomyopa...

Genetics has assumed a pivotal role in clarifying the pathophysiology of cardiomyopathies, facilitating molecular diagnosis, and enabling effective family screening. The advent of next-generation sequencing has revolutionized genetic testing by enabling cost-effective, high-throughput analysis. It is imperative for cardiovascular physicians to mainstream genetic testing into their clinical decision-making. Alth...

Funding Information: This paper was funded by Funda\u00E7\u00E3o para a Ci\u00EAncia e a Tecnologia, reference number UIDB/00306/2020. Publisher Copyright: © 2025 by the authors.; Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia, presenting a significant global healthcare challenge due to its rising incidence, association with increased morbidity and mortality, and economic burden. Th...

Haemodynamic Patterns in Reflex Syncope

Funding Information: This paper was funded by Funda\u00E7\u00E3o para a Ci\u00EAncia e a Tecnologia, reference number UIDB/00306/2020. Publisher Copyright: © 2025 by the authors.; Introduction: Vasovagal syncope is a prevalent condition marked by transient loss of consciousness due to abrupt decreases in systemic blood pressure and/or heart rate. Despite its clinical impact, the underlying haemodynamic mechanis...

Publisher Copyright: © 2025 Sociedade Portuguesa de Cardiologia; Cardiomyopathies may present as a manifestation of various inherited syndromes. Recognizing the rarity and diagnostic challenges of syndromic and metabolic cardiomyopathies is crucial, as their identification holds significant implications for targeted treatment and enables the use of specific risk stratification tools. Genetics has assumed a pivo...

Epicardial adipose tissue volume assessed by cardiac CT as a predictor of atria...

Introduction: In patients with atrial fibrillation (AF), up to one third have recurrence after a first catheter ablation (CA). Epicardial adipose tissue (EAT) has been considered to be closely related to AF, with a potential role in its recurrence. We aimed to evaluate the association between the volume of EAT measured by cardiac computed tomography (CT) and AF recurrence after CA. Methods: Consecutive AF patie...

AFTER-CA

Publisher Copyright: © 2024 by the authors.; Background: Catheter ablation (CA) is a well-established treatment for atrial fibrillation (AF). However, its effects on autonomic function and underlying mechanisms remain poorly understood. This study investigated autonomic and haemodynamic changes following CA and explored their potential implications for patient outcomes. Methods: Seventy-eight patients with AF u...

Orthostatic Stress and Baroreflex Sensitivity

Publisher Copyright: © 2023 by the authors.; The abnormal neural control of atria has been considered one of the mechanisms of paroxysmal atrial fibrillation (PAF) pathogenesis. The baroreceptor reflex has an important role in cardiovascular regulation and may serve as an index of autonomic function. This study aimed to analyze the baroreceptor reflex’s role in heart rate regulation during upright tilt (HUT) in...

Orthostatic stress and baroreflex sensitivity: a window into autonomic dysfunct...

The abnormal neural control of atria has been considered one of the mechanisms of paroxysmal atrial fibrillation (PAF) pathogenesis. The baroreceptor reflex has an important role in cardiovascular regulation and may serve as an index of autonomic function. This study aimed to analyze the baroreceptor reflex's role in heart rate regulation during upright tilt (HUT) in patients with lone PAF. The study included 6...
