Are blood lipid levels and lipid-lowering medications associated with the incidence of atrial fibrillation?
Higher LDLc and total cholesterol are paradoxically associated with a lower incidence of atrial fibrillation, while lipid-lowering medications do not appear to affect AF risk.
Higher levels of LDLc and total cholesterol were associated with a lower incidence of AF. However, HDLc and triglycerides were not independently associated with AF incidence. No association was found between the use of lipid-lowering medications and incident AF.
Lopez et al. (Sat,) studied this question.
