Pre-Hospital Delay and Outcomes in Myocardial Infarction With Nonobstructive Coronary Arteries.

ABSTRACT:

Background and objectives

Real-world evidence on the relationship between delayed hospitalization and outcomes in myocardial infarction with nonobstructive coronary arteries (MINOCA) is lacking. Hence, we aimed to evaluate the clinical characteristics of patients with MINOCA and the 2-year mortality outcomes in this patient population according to the symptom-to-door time (SDT).

Methods

Overall, 861 patients with MINOCA from 2 Korean nationwide observational registries (2011-2020) were included and categorized as early or late presenters. Late presentation was defined as SDT ≥12 hours in patients with ST-segment elevation myocardial infarction (STEMI) and SDT ≥24 hours in patients with non-STEMI. The primary outcome was 2-year all-cause mortality. Propensity score matching (
