Study on the correlation between high density lipoprotein and lower extremities deep venous thrombosis in patients undergoing hip arthroplasty

Objective To explore the relationship between high density lipoprotein (HDL) and lower extremities deep venous thrombosis (DVT) in patients undergoing hip arthroplasty. Methods A total of 348 patients undergoing hip arthroplasty in our hospital were enrolled, and divided into observation ( n = 154, 44.25%) and control ( n = 194, 55.75%) groups according to the occurrence of lower extremities DVT. The presence of DVT was assessed 1 day before surgery and routinely every 2 days after surgery. The factors of DVT were analyzed by single factor analysis, multivariate logistic regression analysis, and Pearson correlation. Results The age and body mass index in the observation group were significantly higher ( p = .045, p = .041, respectively), while HDL-C was significantly lower ( p = .032) than the control group. Increase age, high BMI, low apolipoprotein-A1 level and low HDL-C level were risk factors for lower extremities DVT. The mean HDL-C in the observation and control groups was 0.91 ± 0.27 and 1.19 ± 0.37, respectively, the adjusted odds ratio was 1.050; 95% CI 1.010–1.092, p = .014. Conclusion Elderly patients with high BMI and low HDL-C level undergoing hip arthroplasty are at risk of lower extremities DVT, and should be paid attention to clinically.
