Abstract

Objective: We studied the effect of 24 hr a day, 7 days a week interventional cardiology staff on door-to-balloon (D2B) time and mortality in patients undergoing primary percutaneous coronary intervention (PPCI) for ST-segment elevation myocardial infarction (STEMI). Background: Any delay in PPCI in acute STEMI is associated with higher mortality and, therefore, time to treatment should be as short as possible. Despite the use of several strategies, goal D2B time of <90 min remains elusive. Methods: The study examined 790 consecutive STEMI patients treated with PPCI as the reperfusion therapy of choice. Patients were grouped into a pre-24x7 and post-24x7 cohort to study the impact of the new protocol on D2B time and major adverse cardiovascular events (MACE) and mortality. Results: Median D2B time decreased from 99 min in the pre-24x7 group to 55 min in the post-24x7 group (P = 0.001) and was not influenced by time of day or day of week. Adjusted for patient and clinical characteristics, the pre-24x7 group had increased in-hospital cardiovascular mortality (odds ratio 1.94, 95% confidence interval 0.95-3.94; P = 0.048) and MACE (odds ratio 1.66, 95% confidence interval 1.10-2.49; P = 0.009) compared with the post-24x7 group. Prolonged D2B time was also associated with higher 1-year overall mortality in the pre-24x7 group compared with the post-24x7 group (12.8% vs. 8.1%; hazard ratio 1.17, 95% confidence interval 1.04-2.66; P = 0.044). Conclusions: Round-the-clock, in-hospital interventional cardiology team consistently and significantly reduces D2B time, in-hospital cardiovascular mortality, MACE, and 1-year mortality in patients with STEMI.
