In men who do not have clinically apparent coronary heart disease, the incidental detection of ventricular arrhythmias is associated with a twofold increase in the risk for all-cause mortality and myocardial infarction or death due to coronary heart disease. The preventive and therapeutic implications of these findings await further investigation.

clinicaltrials.gov Identifier: NCT00091637.

In subjects with left ventricular hypertrophy, the presence of asymptomatic ventricular arrhythmias was associated with higher mortality, which was statistically significant after adjusting for age and gender and marginally significant after taking into account other covariates.
