Abstract:
Objective The purpose of the studies was to explore the elective ways to enhance the ability of routine rest To - 99m - sestamibi (MIBI) myocardial scintigraphy to assess myocardial viability during the percutaneous transluminal coronary angioplasty (PTCA ) in assessing viable myocwhium. Methods Three methods, (1) rest- nitroglycerine augment, (2) rest-gated, (3) rest-delayed 99mc - MIBI myocardial scintigraphies, were performed in 20,30 and 10 patients with coronary artery disease treated with coronary revascularization. Results The results showed that in evaluating viable myocardium, the positive predictive values for methods(1 )-(3) were 95. 9%,68. 5% and 84.1%,mepectively, the negative predictive values were 68. 2%, 90. 1% and 90.0%, respecihvely, the predictive accuracy rates were 82. 5%, 77. 3% and 87.2%. Conclusions The results indicate that identification of viable myocardium with 98mTc - MIBI can be effectively enhanced with methods (1) - (3); the 99mTc - MIBI myocardial scintigraphy can provide objective data for evaluating treatment effects by coronary revascularization.
