Characteristics and Causes of Sports-Related Sudden Death in the General Population during the COVID-19 Pandemic.

Purpose: COVID-19 is an independent risk factor for cardiovascular disease. The aim of this study is to determine the burden, characteristics, and causes of sudden death in sport (SrSD) before and after the COVID-19 pandemic in the general population.

Methods: Retrospective observational study.

Variable phenotype of a null PPP1R13L allele in children with dilated cardiomyopathy.

Childhood-onset cardiomyopathy is a genetically heterogeneous group of conditions with several genes implicated. Recently, biallelic loss-of-function variants in PPP1R13L have been reported in association with a syndromic form of dilated cardiomyopathy (DCM). In addition, affected children manifest skin and hair abnormalities, cleft lip and palate (CLP), and eye findings.

Cardiac adaptation to endurance exercise training: Differential impact of swimming and running.

: High-intensity training has been associated with bi-ventricular and bi-atrial remodelling and a potentially increased risk of arrhythmias. Most of the evidence is based on endurance disciplines mainly involving the lower part of the body, while few data is available on upper body disciplines. The purpose of this study was to compare chronic cardiac remodelling induced by running and swimming as well as the acute response of ventricular and atrial performance after an upper-body and a lower-body endurance race.

Macronutrient and mineral intake effects on racing time and cardiovascular health in non-elite marathon runners.

Objective: The aim of this study was to analyze the intake of specific macronutrients and minerals that could influence cardiovascular health in recreational marathon runners.

Methods: We grouped 37 male runners into two groups according to their 50th percentile race time (3.39 h) and divided them into fast (group 1 [G1]: 3.

Aortic root remodelling in competitive athletes.

Background: Controversy remains about the cut-off limits for detecting aortic dilatation in athletes, particularly in large-sized individuals. The allometric scaling model has been used to obtain size-independent measurements in cardiovascular structures in the general population.

Aim: The purpose of this study was to validate the use of allometric scaling in the measurement of the aortic root for competitive athletes and to offer reference values.
