Background: Around 12-20% of patients with conventional pacemakers (PM) and implantable cardioverter-defibrillators (ICD) may develop heart failure, atrial fibrillation, or a reduction in systolic function due to sustained right ventricular pacing, requiring Cardiac Resynchronization Therapy upgrade. This clinical syndrome is collectively referred to as Pacing-induced Cardiomyopathy (PiCMP).
Purpose: Our study aimed to compare different definitions of PiCMP and assess predictors of this cardiomyopathy.
Methods: In this study, we retrospectively collected data from 678 patients who underwent conventional PM or ICD implantation. Three definitions of PiCMP were assessed. The overall population was followed-up for 4.2 (2.6-6.3) years.
Results: The total patient population was 68.1±12.3 years old, baseline left ventricular ejection fraction (LVEF) was 47.5±14.2%, the prevalence of female sex was 31%, and the ischemic etiology 43.6%. Based on the criterions of Kaye et al., 28% of the patient population have developed PiCMP; 52% according to the criterion of Kiehl et al. and 21% according to the criteria of Khurshid et al. and Kim et al. In general, whichever definition was used to assess the outcome, patients diagnosed with PiCMP had lower rates of the female sex and LVEF but higher rates of ischemic etiology and ventricular arrhythmias (VAs). Using multivariate Cox regression analysis LVEF (HR:0.97; 95% CI:0.96-0.99; p=0.001), left bundle branch block (LBBB) (HR:1.82; 95% CI:1.14-2.90; p=0.013), ischaemic heart disease (HR:1.41; 95% CI:1.04-1.95; p=0.035), VAs (HR:1.48; 95% CI:1.06-2.08; p=0.019) and mineralocorticoid receptor antagonist (MRA) (HR:1.49; 95% CI:1.09-2.13; p=0.027) were independent predictors of patients developing PiCMP.
Conclusion: In this study, patients developing PiCMP were found to be more polymorbid than patients receiving conventional treatment. Our multivariate analysis confirmed LVEF, LBBB, ischemic etiology, VAs, and MRA as independent predictors of PiCMP.
