Brief Summary:

This study is to look at the differences between people who have evidence of abnormal heart relaxation (diastolic dysfunction) on sound wave pictures of the heart (an echocardiogram) compared to those who do not. If you have abnormal relaxation, it can be a cause of shortness of breath or can be present without knowing about it.

A condition known as oxidative stress mayb e associated with this abnormal relaxation. This condition occurs when abnormal oxygen injures heart cells. We would like to learn if patients with abnormal relaxation have increased oxidative stress.
