ALB and atrial fibrillation: The higher risk in patients with reduced albumin levels was consistent also for all-cause death (HR, 2.77 [95% CI, 2.70–2.84]), heart failure (HR, 1.31 [95% CI, 1.29–1.34]), atrial fibrillation (HR, 1.11 [95% CI, 1.09–1.13]), ventricular arrhythmias (HR, 1.38 [95% CI, 1.30–1.46]), myocardial infarction (HR, 1.60 [95% CI, 1.54–1.65]), and Takotsubo cardiomyopathy (HR, 1.51 [95% CI, 1.26–1.82]).
