The association between subjective health status and 14-year mortality in post-PCI patients

Abstract

Background: Poor subjective health status significantly predicted short-term mortality in patients with coronary artery disease (CAD). However, the relation between subjective health status and long-term mortality remains limited in patients treated with PCI. The aim of this study is to investigate the association between subjective health status and 14-year mortality in patients treated with percutaneous coronary intervention (PCI).

Methods: A consecutive cohort with 1111 patients treated for CAD who completed the SF-36 questionnaire was included between 2001 and 2002 as part of the RESEARCH registry.

Results: After adjustment, physical functioning (HR: 1.96; 95% CI: 1.59-2.43), social functioning (HR: 1.53; 95% CI: 1.24-1.88), role limitations due to physical functioning (HR: 1.75; 95% CI: 1.41-2.16), role limitations due to emotional functioning (HR: 1.34; 95%CI: 1.08-1.67), mental health (HR: 1.52; 95% CI: 1.24-1.88), vitality (HR: 1.66; 95% CI: 1.35-2.03), bodily pain (HR: 1.63; 95% CI: 1.32-2.02) and general health (HR: 1.82; 95% CI: 1.49-2.23) were all associated with an increased risk of 14-year mortality.

Conclusion: Physical and mental subjective health status as measured with the SF-36 appeared to be a strong predictor for 14-year mortality in post-PCI patients.
