Permanent pacemaker treatment in patients with complete heart block resulted in 50% survival at 5 years, with a 6-7% annual excess mortality compared to a matched population.
Cohort (n=164)
What is the survival rate and excess mortality of patients with complete heart block treated with a permanent pacemaker compared to a matched general population?
Patients with complete heart block treated with permanent pacemakers have a 5-year survival of 50%, with excess mortality primarily driven by coexisting comorbidities rather than the heart block itself.
Effect estimate: 6-7% excess mortality per year
Abstract. A follow‐up study of the survival rate of 164 patients with complete heart block treated with permanent pacemaker showed 87% survival after one year, 76 after two, and 50% after five years. These figures indicate an excess mortality per year in the first five years of 6–7 % compared with a population with the same age and sex distribution. Analysis of the survival curve shows that the excess mortality is caused by other coexisting diseases, such as renal failure, diabetes or cancer, valvular heart diseases or other types of cardiovascular affections, or heart failure.
Hansen et al. (1974) conducted a cohort in complete heart block (n=164). Permanent pacemaker vs. Population with the same age and sex distribution was evaluated on Survival rate at 5 years (6-7% excess mortality per year). Permanent pacemaker treatment in patients with complete heart block resulted in 50% survival at 5 years, with a 6-7% annual excess mortality compared to a matched population.
