May refine post-MI sudden death risk stratification; leaves open whether suppressing these beats improves outcomes.
Cohort (n=1,739)
Does the presence of complex ventricular premature beats increase the risk of mortality in men with prior myocardial infarction?
Effect estimate: RR 3.0
Complex ventricular premature beats identified during a one-hour monitoring period independently predict a significantly increased risk of sudden coronary death and all-cause mortality in men with prior myocardial infarction.
Ruberman et al. (1977) conducted a cohort in Prior myocardial infarction (n=1,739). Complex ventricular premature beats vs. Absence of complex ventricular premature beats was evaluated on Sudden coronary death (RR 3.0). The presence of complex ventricular premature beats in men with prior myocardial infarction is associated with a three-fold increased risk of sudden coronary death.
