[Effects of isometric exercise on the pulmonary circulation in aortic patients].

The hemodynamic changes of the pulmonary vascular system in patients with aortic stenosis, has been evaluated during isometric exercise (handgrip). Heart rate, left ventricular sistolic pressure and pulmonary artery sistolic pressure, increase significantly while pulmonary vascular resistences are uneffected. In conclusion, the pulmonary response to handgrip olso in patients with aortic stenosis shows the same.
