Few studies have focused on the effects of an improved door-to-balloon time on clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to explore the effect of improving door-to-balloon time on prognosis and to identify major predictors of mortality. ⋯ Improving door-to-balloon time could not improve 1-year cardiovascular mortality whether low-risk or high-risk patients. The improvement in the door-balloon time does not improve outcomes studied, probably because it is not accompanied by a reduction in total reperfusion time, which means from onset of symptoms to reperfusion.
