The presence of ventricular premature beats on a resting baseline ECG in survivors of myocardial infarction was associated with increased 3-year mortality compared to no VPB (21.7% vs 11.4%).

Does the presence of ventricular premature beats on baseline ECG increase the risk of death in male survivors of myocardial infarction?
The presence and frequency of ventricular premature beats on a resting baseline ECG independently predict an increased long-term risk of death in male survivors of myocardial infarction.
Absolute Event Rate: 21.7% vs 11.4%
Two hundred thirty-five men among 2,035 survivors of myocardial infarction (11.5%) had one or more ventricular premature beats (VPB) in their resting base-line electrocardiogram. During a three-year follow-up period, deaths were about twice as frequent in those with any VPB (21.7%) as in those with none (11.4%) among the placebo-treated patients in the nationwide Coronary Drug Project. Excess long-term risk of death, including sudden death, was associated with the frequency of VPB, with VPB in pairs or runs, and possibly with early-cycle VPB. The excess risk with these VPB characteristics was independent of the risk associated with other electrocardiographic and clinical characteristics.
A 1973 study conducted a cohort in Myocardial infarction (n=2,035). Ventricular premature beats (VPB) vs. No VPB was evaluated on Death. The presence of ventricular premature beats on a resting baseline ECG in survivors of myocardial infarction was associated with increased 3-year mortality compared to no VPB (21.7% vs 11.4%).
