HR, hazard ratio; CI, confidence interval.
a
Multivariate analysis were calculated by Cox regression models, including atrial fibrillation and right or left bundle branch block.
b
Multivariate analysis were calculated by Cox regression models, including age, body mass index, previous history of hypertension, diabetes mellitus, heart failure, ischemic heart disease, valvular heart disease, chronic obstructive lung disease, chronic renal failure, cerebrovascular accident, atrial fibrillation, beta-blocker medication at discharge, and right or left bundle branch block.
