Abstract:
Objective To investigate the correlation between levels of low-density lipoprotein cholesterol(LDL-C)and atrial fibrillation in a hypertensive population.Methods Hypertension screening was performed in the Wuyuan County of Jiangxi Province from June to August 2022.Data were collected using face-to-face questionnaire surveys,physical measurements,and biochemical tests.Logistic regres-sion analysis was used to analyze the effect of LDL-C on atrial fibrillation.The restricted cubic spline method was used to fit the correlation curve.Results A total of 14 314 patients with hypertension were included in the analysis,with an average age of 65.7±9.2 years.There were 570 patients detected with atrial fibrillation(the rate of atrial fibrillation was 4.0％).The rates of atrial fibrillation for LDL-C＜1.80 mmol/L,1.80-＜2.60 mmol/L,2.60-＜3.40 mmol/L and≥3.40 mmol/L were 10.2％(67/654),5.7％(216/3 807),3.3％(189/5 805),and 2.4％(98/4 048),respectively.Logistic regression analysis showed that,compared with LDL-C＜1.80 mmol/L group,LDL-C 1.80-＜2.60 mmol/L group,2.60-＜3.40 mmol/L group,and ≥ 3.40 mmol/L group had a lower risk of atrial fibrillation(OR=0.53,95％CI:0.39-0.72,P＜0.001;OR=0.32,95％CI:0.23-0.45,P＜0.001;OR=0.22,95％CI:0.16-0.32,P＜0.001).Curve-fitting results showed that LDL-C levels were negatively associated with the risk of atrial fibrillation.Subgroup analysis showed that LDL-C level was negatively associated with the risk of atrial fibrillation in patients without a history of stroke(OR=0.51,95％CI:0.44-0.58,P＜0.001),while the association was not statistically significant in patients with a history of stroke(OR=0.80,95％CI:0.54-1.19,P=0.273).Conclusion In hyperten-sive patients without a history of stroke,LDL-C levels negatively correlated with the risk of atrial fibrillation.
