Dyspnea on exertion is a common manifestation of systolic and diastolic heart failure. Using an MRI-compatible exercise device allowing subjects to exercise while in the bore of the scanner, we assessed exercise-induced changes in diastolic transmitral flow in younger and older healthy volunteers and subjects with pulmonary hypertension. The measurements we obtained demonstrated decreased E/A ratios for older healthy volunteers and PH subjects when compared to younger healthy volunteers, however these differences were not statistically significant.
