Objectives. The aim of this study was to compare health-related quality of life (HRQoL) scores obtained from the instrument Short Form (SF)-36 through the so-called SF-6D utilities, and those obtained from 15D, in patients with ST-elevation myocardial infarction (STEMI), and to evaluate the consequences in estimation of quality adjusted life years (QALYs). Design. This was a sub-study of the Norwegian District Treatment of STEMI, in which patients with STEMI treated with tenecteplase, were randomized to early angioplasty or standard management ( n = 266). HRQoL data were collected at all visits (0, 1, 3, 7 and 12 months). All patients with complete data were included ( n = 248). Results. The score range was 0.33-1.0 for SF-6D and 0.49-1.0 for 15D. Mean utility scores from 15D were higher and had different distribution compared to scores from SF-6D. Mean QALY for the whole group was higher using 15D than SF-6D (0.89 vs. 0.77). The incremental number of QALYs with early angioplasty compared to standard treatment was 0.005 (95% CI: − 0.018 to 0.028) using SF-6D, and 0.004 (95% CI: − 0.010 to 0.018) using the 15D instrument. Conclusions. Choice of instrument may influence HRQoL scores, but not necessarily the gain in QALYs. [ABSTRACT FROM AUTHOR]

Objectives. Thrombolysis is the treatment of choice for patients with ST-elevation myocardial infarction (STEMI) living in rural areas with long transfer delays to percutaneous coronary intervention (PCI). This trial compares two different strategies following thrombolysis: to transfer all patients for immediate coronary angiography and intervention, or to manage the patients more conservatively. Design. The NORwegian study on DIstrict treatment of STEMI (NORDISTEMI) is an open, prospective, randomized controlled trial in patients with STEMI of less than 6 hours of duration and more than 90 minutes expected time delay to PCI. A total of 266 patients will receive full-dose thrombolysis, preferably prehospitally, and then be randomized to either strategy. Our primary endpoint is the one year combined incidence of death, reinfarction, stroke or new myocardial ischaemia. The study is registered with ClinicalTrials.gov, number NCT00161005. Results. By April 2006, 109 patients have been randomized. Thrombolysis has been given prehospitally to 52% of patients. The median transport distance from first medical contact to catheterization laboratory was 155 km (range 90–396 km). Results of the study are expected in 2008. [ABSTRACT FROM AUTHOR]
