Health-related quality of life one month after thrombolysis or primary PCI in patients with ST-elevation infarction. A DANAMI-2 sub-study

Abstract

Objectives. To evaluate the health-related quality of life (HRQoL) following Primary percutaneous coronary intervention (PCI) or thrombolytic treatment for ST-elevation myocardial infarction (STEMI). Design. A questionnaire based study on patients randomised in the DANAMI-2 study to Primary PCI or thrombolysis for STEMI. A total of 1351 patients (93.2% response rate) randomised in the DANAMI-2 study completed the HRQoL questionnaire one month after the infarction. Results. With respect to the primary end-points (SF-36 physical component score, angina pectoris, and dyspnoea), patients randomised to primary PCI scored better on the SF-36 physical component score (PCS) (p=0.007), and reported significantly less angina pectoris (p=0.010) and dyspnoea (p=0.010). Higher scores among PCI patients were also found on the SF-36 scales physical functioning (p=0.015), role-physical (p=0.017), and general health (p=0.009). Conclusion. The results in this study support the hypothesis that primary PCI is superior to thrombolysis in treating STEMI, not only in clinical outcome, but also in quality of life outcome. © 2005 Taylor & Francis.
