APOA1 and atrial fibrillation: The results for ApoA-I were similar to that of HDL-C, where low ApoA-I (<1.28 g/L) was associated with a higher risk of AF over the follow-up (HR = 1.53, 95% CI: 1.12 to 2.00, p = 0.007; HR = 1.37, 95% CI: 1.12 to 1.67, p = 0.002; HR = 1.05, 95% CI: 1.00 to 1.10, p = 0.065).
