RESUMEN
System delay (delay from emergency medical service call to reperfusion with primary percutaneous coronary intervention [PPCI]) is acknowledged as a performance measure in ST-elevation myocardial infarction (STEMI), as shorter system delay is associated with lower mortality. It is unknown whether system delay also impacts ability to stay in the labor market. Therefore, the aim of the study was to evaluate whether system delay is associated with duration of absence from work or time to retirement from work among patients with STEMI treated with PPCI. We conducted a population-based cohort study including patients ≤67 years of age who were admitted with STEMI from January 1, 1999, to December 1, 2011 and treated with PPCI. Data were derived from Danish population-based registries. Only patients who were full- or part-time employed before their STEMI admission were included. Association between system delay and time to return to the labor market was analyzed using a competing-risk regression analysis. Association between system delay and time to retirement from work was analyzed using a Cox regression model. A total of 4,061 patients were included. Ninety-three percent returned to the labor market during 4 years of follow-up, and 41% retired during 8 years of follow-up. After adjustment, system delay >120 minutes was associated with reduced resumption of work (subhazard ratio 0.86, 95% confidence interval 0.81 to 0.92) and earlier retirement from work (hazard ratio 1.21, 95% confidence interval 1.08 to 1.36). In conclusion, system delay was associated with reduced work resumption and earlier retirement. This highlights the value of system delay as a performance measure in treating patients with STEMI.

AIMS: To compare deliverability and in-hospital complications in implantation of BxSonic(R), Express(R), and Flexmaster(R) coronary stents in a randomized multicenter trial in five Danish interventional centres. METHODS AND RESULTS: Patients with planned stenting of at least one stenotic lesion in a native coronary artery were included in the study. There were 494 (664) patients (treated lesions) in the BxSonic(R), 499 (657) in the Express(R) and 500 (658) in the Flexmaster(R) groups. The groups were well matched with regard to age, sex, diabetes, smoking, hypercholesterolemia, hypertension, indication for PCI and coronary artery lesion complexity. The study stents were implanted with or without predilatation according to ordinary -clinical practice.Rates of successful stent implantation and in-hospital stent thrombosis, re-intervention, non-fatal myocardial infarction or death. The BxSonic(R), Express(R) and Flexmaster(R) stents were successfully implanted in 92,2%, 89,3% and 91,6% of all lesions (ns). There were no in-hospital deaths and the rates of in-hospital complications were similar in the three stent groups. CONCLUSION: We found similar deliverability and in-hospital complication rates of the BxSonic(R), Express(R) and Flexmaster(R) stents.
