[Work load hemodynamics before and after aortocoronary bypass].
Left ventricular enddiastolic pressure (LVEDP) was studied during exercise in 22 patients pre- and postoperatively under an identical work load. 13 patients showed improvement of LVEDP (normalization in 5), LVEDP was unchanged in 5 (w.n.l. in 2), and had deteriorated in 4. These results suggest that improvement or normalization of LVEDP under exercise following aortocoronary bypass surgery can be assumed if there is complete revascularization, if all grafts are functioning well, if there is no progression of the underlying disease, and if preoperative LV angiography is normal or shows only ischemic (reversible) hypokinesis.
