Aims: This study compared health-related quality of life (HRQOL) between patients aged ≥. 70 and < 70 years at 4 weeks and 6 months after primary percutaneous coronary intervention (PPCI) and examined predictors of HRQOL. Background: HRQOL is an important patient outcome following PPCI for ST elevation myocardial infarction (STEMI) including pre-hospital field triage. Methods: A comparative cohort design was conducted on STEMI patients undergoing PPCI. HRQOL was measured using the Medical Outcomes Short Form-12 (SF-12) and the Seattle Angina Questionnaire (SAQ) at 4 weeks and 6 months post-PPCI. Results: HRQOL improved significantly from 4 weeks to 6 months in all aspects measured except anginal frequency and mental health. Patients aged ≥. 70 years had poorer physical HRQOL (SF-12) and physical limitations (SAQ), but better mental HRQOL (SF-12), angina frequency and QOL (SAQ) at both time points. Age, length of hospital stay, gender, partnership status and number of stents deployed are independent predictors of HRQOL improvement over time. Conclusion: People ≥ 70 years reported better cardiac-specific quality of life, primarily from angina relief and improved mental function, despite worse physical limitations. HRQOL assessment is an important gauge of health status after PPCI for STEMI.
