STEMI Mortality Reduced With Admission to Primary PCI Center

HealthDay News – For patients with ST-segment elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI), direct admission to a primary PCI center is associated with lower 12-month mortality, according to a study published online in JACC: Cardiovascular Interventions.

Using data from a prospective nationwide registry, Damian Kawecki, MD, PhD, from the Medical University of Silesia in Poland, and colleagues examined the impact of direct admission vs transfer via regional hospital to a PCI center on time delays and 12-month mortality in STEMI patients. A total of 70,093 patients were eligible for analysis, of whom 56% were admitted directly to a PCI center.

The researchers found that direct admission correlated with a 44-minute shorter median symptoms-to-admission time (P <.001) and total ischemic time (228 vs 270 minutes; P <.001), higher left ventricle ejection fraction (47.5% vs 46.3%; P <.001), and lower propensity-matched 12-month mortality (9.6% vs 10.4%; P <.001). Direct admissions and shorter symptoms-to-admission time were significant predictors of lower 12-month mortality in propensity matched analysis (hazard ratios, 1.06 and 1.03, respectively).

“In a large, community-based cohort of patients with STEMI treated by PCI, direct admission to a primary PCI center was associated with lower 12-month mortality and should be preferred to transfer via a regional non-PCI-capable facility,” the authors wrote.
