Key result
Pulmonary hypertension (OR 5.08), reoperation (OR 4.51), and pre-existing left bundle branch block (OR 2.0) were identified as significant independent predictors of permanent pacemaker implantation after cardiac surgery.

Pulmonary hypertension, reoperation, and pre-existing left bundle branch block are significant predictors of permanent pacemaker requirement after cardiac surgery, with a majority of these patients remaining pacemaker-dependent at long-term follow-up.
Al‐Ghamdi et al. (2016) conducted a cohort in Coronary artery disease and/or valvular heart disease requiring surgery (n=1,234). Pulmonary hypertension vs. Absence of pulmonary hypertension was evaluated on Permanent pacemaker implantation (OR 5.08, 95% CI 1.941-13.296, p=0.001). Pulmonary hypertension (OR 5.08), reoperation (OR 4.51), and pre-existing left bundle branch block (OR 2.0) were identified as significant independent predictors of permanent pacemaker implantation after cardiac surgery.
