The Price of Time: 20-Year Study Reveals Pre-Hospital Delay as a Critical Driver of STEMI Mortality

By MedXY 01/03/2026

A 20-year analysis of 89,155 patients from the SWEDEHEART registry confirms that pre-hospital delay independently predicts short- and long-term mortality. Despite advances in reperfusion, women, elderly patients, and those with diabetes consistently experience significantly longer delays, highlighting a critical need for targeted public health interventions.
