Abstract Background: This study is comprised of 3493 consecutive patients who underwent open heart surgery at our institution. Data on all patients were collected prospectively. Methods: In 45 patients (Group P) (1.3%), a permanent pacemaker (PP) was inserted postoperatively. For the purpose of the study, these patients were compared to 3448 patients (Group NP) who did not require insertion of a PP after surgery. Mean follow-up was 33 months (range 1.5 to 66). Results: We found Group P patients were older (64.8 ± 11.0 vs 61.0 ± 11.0 years, p 〈 0.05), had a higher proportion of elderly (〉 70 years) (36% vs 19%, p = 0.01), and of female patients (48.8% vs 22.7%, p 〈 0.001) compared to Group NP. Group P also had a higher incidence of preoperative rhythm abnormalities (26.6% vs 5.7%, p 〈 0.0001), redo surgery (13.3% vs 4.6%, p = 0.02), aortic valve surgery (48.8% vs 10.8%, p 〈 0.001), and tricuspid valve surgery (repair 3, replacement 1) (8.8% vs 0.5%, p 〈 0.001), in addition to a higher proportion of patients in whom cold (vs warm) blood cardioplegia was used (68.8% vs 52.3%, p = 0.03). Indication for postoperative PP was sick sinus syndrome (SSS) in nine patients; atrial fibrillation in eight patients; atrioventricular block (AVB) in 27 patients; and combined AVB/SSS in 1 patient. There were no operative deaths in Group P. Necessity for PP after heart surgery had a significant impact on resource utilization resulting in prolonged ventilation (3.1 ± 7.5 vs 1.4 ± 3.3 days, p 〈 0.01), intensive care unit (5.1 ± 10.2 vs 2.5 ± 4.0 days, p 〈 0.01), and postoperative hospital stay (18.0 ± 13.4 vs 8.1 ± 9.4 days, p 〈 0.01). Conclusions: By multivariate logistic regression (odds ratio and p value in parentheses), aortic valve surgery (8.23, p = 0.001), the absence of preoperative sinus rhythm (5.60, p = 0.001), postoperative myocardial infarction (3.46, p = 0.024), and female gender (2.52, p = 0.003), were found to be independent predictors for PP requirement post surgery.
