ACUTE CORONARY SYNDROME, ISCHEMIA
A total of 301 patients were randomized, with 151 patients assigned to receive PCI and 150 to placebo. The mean age of patients was 64±9 years and 79% were male. Ischemia was present in one cardiac territory in 242 patients (80%), two territories in 52 patients (17%) and three territories in 7 patients (2%). The median fractional flow reserve was 0.63 (interquartile range, 0.49 to 0.75) and the median instantaneous wave-free ratio was 0.78 (interquartile range, 0.55 to 0.87). At 12-week follow-up, the angina symptom score was 2.9 for patients assigned to PCI and 5.6 for patients assigned to placebo (odds ratio 2.21; 95% confidence interval, 1.41 to 3.47, p<0.001). One patient in the placebo arm had intolerable angina. Acute coronary syndromes occurred in 4 patients in the PCI group and 6 in the placebo group.
