Key result
Recovery premature ventricular complexes were associated with increased mortality compared to subjects without PVCs (HR 1.96; 95% CI 1.31-2.91 for infrequent PVCs).

Does the presence of exercise or recovery premature ventricular complexes increase mortality in heart failure-free patients undergoing treadmill testing?
Hazard Ratio: 1.96 (95% CI 1.31–2.91)
Frederick E. Dewey (2008) conducted a cohort in Heart failure-free patients undergoing clinical treadmill testing (n=1,847). Recovery premature ventricular complexes (PVCs) vs. Subjects without PVCs was evaluated on Mortality (HR 1.96, 95% CI 1.31-2.91). Recovery premature ventricular complexes were associated with increased mortality compared to subjects without PVCs (HR 1.96; 95% CI 1.31-2.91 for infrequent PVCs).
