Abstract 17929: Contemporary Door-to-Balloon Times With Primary Percutaneous Coronary Intervention in Elderly versus Younger Patients Presenting With Acute ST-Segment Elevation Myocardial Infarction
Introduction: Primary percutaneous coronary intervention (PPCI) is the choice reperfusion strategy for acute ST-segment elevation myocardial infarction (STEMI). However, data on door-to-balloon (D2B) times in elderly patients compared to younger patients is nonexistent.
Objective: This study determined D2B time in elderly versus younger patients with STEMI revascularized by PPCI.
Methods: A cohort of 790 consecutive STEMI patients was studied for D2B time after PPCI using a precise cardiac catheterization protocol. Patients were divided into two groups: those ≥75 years (elderly) and those <75 years.
Results: Median D2B time was 82 min in the elderly vs. 66 min in the younger group (p=0.002). In-hospital all-cause mortality was higher in the elderly group (15.5% vs. 2.7%, p<0.001). Variables associated with increased D2B times are shown in the table. All of these characteristics except renal failure were noted in the elderly population.
Conclusions: In a contemporary population of STEMI patients treated with PPCI with no difference in the cardiac catheterization protocol, elderly patients had higher D2B times than patients <75 years of age.
