Asymptomatic frequent VPDs may signal higher cardiomyopathy risk; leaves open whether symptoms should guide surveillance intensity in prospective cohorts.
Is asymptomatic presentation associated with a higher risk of left ventricular dysfunction in patients with frequent ventricular premature depolarizations?
Asymptomatic patients with frequent ventricular premature depolarizations have a higher incidence of left ventricular dysfunction than symptomatic patients, suggesting absence of symptoms may be a risk factor for cardiomyopathy.
Park et al. (2015) studied this question.
