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

NCT01747785 · Status: TERMINATED · Type: OBSERVATIONAL · Enrollment: 21

Last updated 2016-05-17

No results posted yet for this 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.

Conditions

Interventions

OTHER

Cardiac rehabilitation

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

OTHER

Myocardial deformation imaging

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.

OTHER

Cardiopulmonary exercise test

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.
