Myocardial Performance at Rest and During Exercise in Heart Failure With Preserved Ejection Fraction

Aerobic cardiac exercise training will be provided over the 12 week study duration.

A 2D Doppler echocardiograph (image) of the heart will be captured during a single heart beat taken at rest and during cardiopulmonary exercise tests to measure left and right ventricular segmental systolic and diastolic strain measurements.

The cardiopulmonary exercise test consists of cycling exercise of mild and moderate intensity on an upright cycle ergometer on a tilting table (to facilitate imaging) for 6-10 minute periods within a one hour session.
