Abstract: Left ventricular endsystolic wall stress（LVESWS） and fractional shortenness（FS）, standing for left ventricular systolic preservation function, was measured in 34 elderly patients with nonrhumatic aortic regurgitation（NRAR） and 30 controls before and after physical exercise by using echocardiography. After 5 years followup, the patients were divided into two groups: Group A（deteriorized condition） and Group B（remaining unchanged clinically）. The result of the study showed that although such indexes as LVMI, systolic pressure, LV diameter, ventricular wall thickness, FS and LVESWS at rest were similar in both the groups, FS and LVESWS after exercise were significantly different （P＜0.01）. So the author come to the conclusion that FS and LVESWS before and after the physical exercise may be usful indexes for determining prognosis of NRAR in elderly patients.
