Prognostic implications of ventricular ectopy one week, one month, and sixteen months after an acute myocardial infarction. Danish Study Group on Verapamil in Myocardial Infarction.

Background: Ventricular ectopy early after an acute myocardial infarction (AMI) has previously been demonstrated to predict mortality. Less information is available about the prognostic implications of ventricular ectopy occurring late after an AMI, and no information is available about the prognostic implication of the development of ventricular ectopy during the first year after an AMI.

Hypothesis: The purpose of the present prospectively conducted trial, a part of the Danish Verapamil Infarction Trial II (DAVIT II), was to evaluate the prognostic implication of (1) ventricular premature complexes (VPCs) recorded by 24-h Holter monitoring 1 week, 1 month, and 16 months after an AMI; and (2) development of > 10 VPCs/h or of any complex ventricular ectopy, that is, pairs, more than two types of VPCs, ventricular tachycardia, or > 10 VPCs/h during follow-up after an AMI.

Angiotensin-converting enzyme (ACE) inhibitors improve survival in patients with congestive heart failure (CHF) after an acute myocardial infarction (AMI), but mortality may be as high as 10% to 15% after 1 year. Verapamil prevents cardiac events after an AMI in patients without CHF. We hypothesized that in postinfarct patients with CHF already prescribed diuretics and an ACE inhibitor, additional treatment with verapamil may reduce cardiac event rate.

Unlabelled: EFFECTS OF VERAPAMIL AND TRANDOLAPRIL: Progression of heart failure, sudden death and death from re-infarction are the major cause of the increased mortality in postinfarct patients with congestive heart failure. Angiotensin converting enzyme (ACE) inhibitors such as trandolapril can prevent the progression of heart failure and thus improve survival. The calcium antagonist verapamil has been shown to prevent sudden death and re-infarction in postinfarct patients without congestive heart failure.

The present study was a prospectively planned subset of the postinfarction, double blind, randomized, multicenter, placebo controlled trial of verapamil, DAVIT II. Patients had 24 hours of Holter monitoring before randomization, i.e.
