The P-values shown are derived from two-tailed Fisher’s exact test for categorical variables and two-tailed unpaired Student’s t-test for continuous variables. Patients who were non-RV pacing-dependent at 30 days and patients who were RV pacing-dependent at 30 days patients were separately compared with the non-pacemaker population to derive these P-values. Continuous variables are reported as the mean plus or minus the standard deviation. RV: right ventricular; PPM: permanent pacemaker; BMI: body mass index; DM: diabetes mellitus; CAD: coronary artery disease; CHF: congestive heart failure; COPD: chronic obstructive pulmonary disease; PVD: peripheral vascular disease; eGFR: estimated glomerular filtration rate; CABG: coronary artery bypass grafting; PCI: percutaneous coronary intervention; ACE-I/ARB: angiotensin converting enzyme inhibitor/angiotensin receptor blocker.
