Relationship between exercise capacity and left ventricular function in aortic and mitral regurgitation.

ABSTRACT

The exercise capacity as assessed by treadmill exercise or functional class from clinical history cannot predict standard echocardiographic findings in patients with AR/MR, in terms of EF, LVDs, ESVI. Therefore, exercise capacity cannot be used to predict the timing for surgery in those patients. However, symptomatic patients with dilated LV usually have low LVEF such as in our group.
