Exercise-induced left ventricular remodeling among elite endurance athletes

Abstract: Background: Cardiac remodeling in response to long term athletic training has been a well-described phenomenon in humans which leads to myocardial adaptations, with remodeling of the cardiac chambers especially the left ventricle resulting in changes in heart rate and arterial blood pressure. Aim / Objective: The aim of this study was to evaluate the effect of maximal exercise on the heart rate, blood pressure and level of cardiac remolding in elite athletes as compared to sedentary healthy subjects. Place and Duration of Study: The present study was carried out at the Department of Physiology, Army Medical College, with collaboration of Armed Forces Institute of Cardiology (AFIC)...

Secretion of Atrial Natriuretic Peptide (ANP), heart reconditioning and remolding in elite endurance trained athletes

ABSTRACT Aim / Objective: The aim of this study was to evaluate the effect of maximal exercise on the level of cardiac remolding and Atrial Natriuretic Peptide (ANP) in elite athletes as compared to sedentary healthy subjects and correlation of ANP with the adaptation of athlete’s heart and cardiac remodeling (if any) Place and Duration of Study: The present study was carried out at the Department of Physiology, Army Medical College, with collaboration of Armed Forces Institute of Cardiology (AFIC) Rawalpindi from June 2003 to May 2004. Methodology: A total number of 44 subjects were included in this study. These comprised of 22 elite endurance athletes and 22 healthy sedentary volunteers as...
