Development and validation of a risk score for predicting 30-day mortality in patients with ST elevation myocardial infarction.

ABSTRACT: The existing risk sores for ST-elevation myocardial infarction (STEMI) patients cannot balance timeliness, feasibility, and accuracy. This study aimed to develop and validate a two-stage scoring system capable of dynamic evaluation for 30-day mortality among STEMI patients. We recruited 3939 patients and randomly assigned (7:3) to derivation (N = 2757) and internal validation (N = 1182) datasets, an independent cohort of 1315 STEMI patients was used for external validation. The two-stage scoring system was developed based on factors associated with 30-day mortality identified by multivariate analysis and their availability in course of management. The first medical contact (FMC) stage risk score comprised six predictors (age, gender, systolic blood pressure, heart rate, Killip class, and a
