The following covariates were included in the multivariable analyses: age, previous myocardial infarction, diabetes mellitus, congestive heart failure, left ventricular ejection fraction <40%, cardiogenic shock, AHR range, and β‐blocker use on admission. Covariates not presented in the final model were non–statistically significant. AHR indicates admission heart rate; bpm, beats per minute; RCA, right coronary artery.

^aAHR 60 to 79 bpm was used as reference.
