Abstract

Background: Regular training, in particular endurance exercise, induces structural myocardial adaptation, so-called "athlete's heart". In addition to the 2D standard echo parameters, assessment of myocardial function is currently possible by deformation parameters
Objective: To determine the impact of measures of cardiac function assessed by echocardiography on exercise capacity and to determine if these associations are modified by sex or advancing age.
Methodology: The Study was conducted on 100 subjects at Haldiram and Moolchand Heart Centre, PBM Hospital, S.P. Medical College, Bikaner. First a resting echocardiography was performed to evaluate cardiovascular diastolic function. After echocardiography the subjects were underwent Bruce protocol treadmill test.
Result & Conclusion:: There was no correlation between exercise capacity and end systolic volume index (p=0.089), between exercise capacity and ejection fraction(p=0.459), between exercise capacity and fractional shortening(p=0.467), between exercise capacity and stroke volume index(p=0.361), between exercise capacity and  cardiac index(p=0.475).
