Study Summary
This study is being done to study how well the heart contracts and relaxes during exercise. In addition to traditional measures of heart function, we will use a new computer program that may improve understanding of why people feel shortness of breath or fatigue.
Primary Outcome
Myocardial deformation imaging (e.g. strain, strain rate, torsion) requires clear 2-dimensional echocardiography images that will be obtain at rest and during mild and moderate intensity exercise. Images will be captured during 6-10 minute bouts of exercise on a tilting exercise table. Comparisons will be made on resting and exercise values between groups. Our hypothesis is that strain rate will not increase in patients at risk of heart failure demonstrating lack of cardiovascular reserve.
Interventions
- OTHER Cardiopulmonary exercise test
- OTHER Cardiac rehabilitation
- OTHER Myocardial deformation imaging
