Correlation of exercise capacity with left ventricle diastolic function

Introduction: Exercise may be good for the heard but good diastolic function also appears to protect the capacity for exercise researchers found. Objectives: To correlate exercise capacity with the left ventricle diastolic function. Material and methods: 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. Results: Diastolic dysfunction was strongly and inversely associated with exercise capacity. Compared with normal function, those with resting diastolic dysfunction had substantially lower exercise capacity. Conclusion: Left ventricular diastolic function were independently associated with exercise capacity.

Correlation of exercise capacity with Cardiovascular systolic function

Introduction: The analysis of systolic function in echocardiography may be useful to explain the correlation between the presence of systolic function and maximal exercise capacity on exercise test. Objectives: To correlate exercise capacity with the cardiovascular systolic function. Material and methods: Necessary information as per our study was collected from the hospital record of the study participants undergoing routine measurements of systolic function by 2D echocardiography and exercise capacity (VO2max) by treadmill test using bruce protocol. Results: Karl Pearson correlation analysis showed that cardiovascular systolic functions in our group do not correlate with exercise capacity. There was no correlation between exercise capacity and end systolic volume index (r=-0.171, p<0.089), between exercise capacity and ejection fraction (r=0.069, p<0.495), between exercise capacity and fractional shortening (r=0.074, p<0.467), between exercise capacity and stroke volume index (r=-0.092, p<0.o.361), and cardiac index (r=-0.072, p<0.475) also showed no significant association with exercise capacity. Conclusions: Correlation analysis showed that cardiovascular systolic functions in our group do not correlate with exercise capacity.
