Oxidative Stress Markers in Heart Failure II

Recruiting

This research is being done to better understand why people develop a type of heart failure where the heart contracts normally but does not relax well. By comparing levels of chemicals in the blood that are secreted by the body in subjects with normal hearts and in subjects with abnormal relaxation, we hope to gain a better understanding of why heart failure occurs.
