Prospective Assessment of Premature Ventricular Contractions Suppression in Cardiomyopathy(PAPS)

Status unconfirmed · Phase 4

Conditions studied: Ventricular Premature Beats, Contractions, or Systoles, Cardiomyopathies

In brief

Premature ventricular contractions (PVCs) coexist in patients with heart failure (HF) and LV dysfunction. Frequent PVCs have shown to induce a reversible cardiomyopathy (PVC-CM). This clinical pilot study will enroll 36 patients with frequent PVCs (burden \>10%) and CM (LVEF \<45%) and randomize them to either: 1) RFA or 2) AADs. Prior to treatment, patients will undergo a baseline cardiac MR if clinically indicated followed by 3-month observation period (optimal HF medical therapy). Changes in LV function/scar, PVC burden/arrhythmias and clinical/functional status (QOL, HF symptoms and admissions, NYHA class) and adverse events will be assessed throughout the observation period and compare with PVC suppression strategies (RFA or AAD). Similar comparison will be made between RFA and AAD treatment groups during a 12-month follow up using a Prospective Randomized Open, Blinded End-point (PROBE) study design. The treatment regimens will be compared in an intention-to-treat analysis. In addition, a total of 20,000 consecutive ambulatory ECG Holter monitors from all participating centers will be screened to identify all patients with probable diagnosis of PVC-CM. This pilot study is intended to estimate the prevalence of this clinical entity and pave the way for a large full scale randomized trial to identify best treatment strategy for patients with PVC-CM. Treating and reversing this underestimated PVC-CM may improve patient's health and subsequently decrease HF healthcare spending.
