Coronary artery revascularization after myocardial infarction.

Authors report on the revascularization resulted by noninvasive and invasive interferences carried out 6-9 months after surgery and on the improvement of functional status of 56 postinfarction patients with recurrent angina pectoris. They conclude that recoronarography performed in 12 patients revealed diminished patency rate as compared to the estimated rate, especially in those cases, where complete revascularization was considered to have been carried out. Ejection fraction, wall motion score by ventriculography and echocardiography did not seem to improve significantly. However Dipyridamole Thallium scintigraphy showed marked improvement in perfusion in all cases. NYHA functional status noticeably improved in the re-examined patients.
