Abstract
BACKGROUND: Few studies describe recent changes in the incidence, treatment and outcome of successfully resuscitated STEMI patients after out-of-hospital cardiac arrest (OHCA) compared with non-OHCA STEMI patients. OBJECTIVE: To examine temporal trends in the incidence, therapeutic management, most serious complications, mortality rate and outcome of OHCA patients fulfilling criteria of STEMI compared with a reference group of STEMI patients without OHCA. METHODS: Analysis of registry data (AMIS Plus Registry) among STEMI patients both with and without OHCA between 1997 and 2017. RESULTS: Among 31,650 patients with STEMI, 6.8% were successfully resuscitated prior to hospital admission. Increasing incidences of hospital-admitted patients following successful out-of-hospital CPR were observed (4.5% in 1999 vs. 8.6% in 2017). OHCA STEMI patients were at higher clinical risk at presentation (36.1% vs. 2.7%; p < 0.001 with cardiogenic shock) despite a shorter time span from the onset of symptoms to hospitalization (195 min vs. 107 min; p < 0.001) and a lower prevalence of cardiovascular risk factors except smoking. More PCIs were performed in STEMI patients with OHCA (78.9% vs. 74.5% for non-OHCA patients; p < 0.001). However, over time PCI became the preferred primary intervention irrespective of the OHCA status of STEMI patients. For STEMI patients without OHCA, there was a significant correlation between PCI and time periods on in-hospital mortality (p < 0.001), which was p = 0.002 when adjusted for age and gender. For STEMI patients with OHCA, the interaction between PCI and time was unadjusted p = 0.395 and p = 0.438 when adjusted for age and gender.
