“…For each patient with an initial confirmed AMI satisfying our geographic and clinical eligibility criteria, a variety of sociodemographic, clinical, medical care, and outcome related information was collected and entered onto a standardized case-report form based on our previous studies of AMI [9][10][11]. Information was collected about patient's age, sex, marital status, hospital transport by ambulance and medications administered en route, cardiovascular comorbidities (e.g., diabetes, hypertension, heart failure, stroke), admission clinical and laboratory parameters, AMI type (STEMI vs. NSTEMI), receipt of effective cardiac medications and coronary interventional procedures during the index hospitalization, clinically significant in-hospital complications (e.g., stroke, cardiogenic shock, heart failure, atrial fibrillation), hospital discharge status, and length of hospital stay.…”
