    DAVIT-II is a double-blind, randomized, multicentre, placebo-controlled study of long-term treatment with verapamil 360 mg per day administered to patients who have suffered an acute myocardial infarction (AMI). In the present study, comprising a subset of DA VIT-II, 48 h continuous ECG recordings demonstrated transient ST segment deviation indicative of myocardial ischaemia after one week, prior to randomization, in 18% (10 of 57) of the patients. After one month, 24% (11 of 46) of the placebo and 8% (3 of 39) of the verapamil-treated patients (P=0.04) had myocardial ischaemia; after one year the figures were 26% (9 of 35) and 4% (1 of 27) (P=0.02), respectively. At 18 months the 'major' event rate in patients who had had ischaemia before randomization was 40% and 23.8% in patients without ischaemia (P=0.057). In the placebo group, 63% of 91 episodes of ST depression were recorded between 0600 h and 1800 h, and 62% of 26 episodes of ST elevation between 1800 h and0600 h(P<0-001). Nine episodes of ST depression and no episode of ST elevation were recorded in the verapamil-treated patients. In conclusion, 20-25% of post-AM I patients have transient ischaemia; verapamil prevents ischaemia, and a pronounced circadian variation of ST segment deviations can be demonstrated.
