A Cox proportional hazards regression analysis for the same association, adjusted for sex, age, elevated troponin, comorbidities (atrial fibrillation, ischemic heart disease, heart failure, diabetes mellitus, chronic kidney disease, cerebrovascular accident, and hypertension), chronic medications (beta-blockers, angiotensin-converting-enzyme inhibitors [ACEI] or angiotensin II receptor blocker [ARBS], HMG CoA reductase inhibitors), low admission systolic blood pressure, admission creatinine level is presented in Table 4. Here, HMGCR is linked to atrial fibrillation.
