Abstract: | One-hundred and seven patients with unstable angina were treated between 1981 and 1987. Platelet dysfunction and elevation of fibrinogen was observed. The efficacy of aspirin, dipyridamole and heparin on coagulation profile is compared. Left main disease was seen in 11.4 per cent. Left anterior descending was occluded in 90.7 per cent. Aortocoronary bypass graft using saphenous vein graft was carried out on all patients. On an average, each patients received 3.5 grafts. Emergency surgery was done in nineteen. Associated ventricular aneurysm was resected in nine. Thirteen patients died. Operative mortality decreased to nil in 1986–1987. Perioperative infarction was seen in five patients. Clinical improvement was seen in 80.3 per cent and 48.9 per cent were asymptomatic. Actuarial survival was 92 per cent after six years. Postoperative coronary angiography in 28 patients showed patency of grafts in 18, partial patency in six and occlusion in four. Aspirin was found useful after surgery to relieve angina. Spiroergometry and Thallium201 scintigraphy was useful to assess medical and surgical treatment. |
