Key result
Permanent pacing in patients with sinoatrial block showed 1-, 2-, 5-, and 8-year survival of 94%, 85%, 64%, and 48%, with 4-5% excess yearly mortality driven by coexisting diseases.
Why the study?
What is the long-term survival of patients with sinoatrial block treated with a permanent pacemaker compared to an age- and sex-matched population?
Cohort (n=50)
What is the long-term survival of patients with sinoatrial block treated with a permanent pacemaker compared to an age- and sex-matched population?
Effect estimate: 4-5% excess yearly mortality
Patients with SA block treated with permanent pacing experience an excess yearly mortality of 4-5% in the first five years, which is primarily driven by coexisting coronary and valvular heart diseases.
No takes yet. Share an insight, caveat, or question.
Excess mortality after pacing for sinoatrial block is comorbidity-driven; leaves open whether intensified coronary and valvular disease management improves prognosis.
Skagen et al. (1976) conducted a cohort in Sinoatrial block (n=50). Permanent pacemaker vs. Population of the same age and sex was evaluated on Survival (4-5% excess yearly mortality). Permanent pacing in patients with sinoatrial block showed 1-, 2-, 5-, and 8-year survival of 94%, 85%, 64%, and 48%, with 4-5% excess yearly mortality driven by coexisting diseases.
