Monocyte count-to-high-density lipoprotein-cholesterol ratio is associated with abdominal aortic aneurysm size

Aim: To determine the association of monocyte count-to-high-density lipoprotein (HDL)-cholesterol ratio, a recently emerged inflammatory marker, with abdominal aortic aneurysm (AAA) size. Patients & methods: A total of 120 asymptomatic AAA subjects (99 male, mean age: 67.1 +/- 10.2 years) were enrolled into the study. All data were compared between patients with low and high admission monocyte/HDL ratio. Multivariate linear regression analysis was performed to study the relationship between different variables and AAA size. Results: Compared to patients with below-median monocyte/HDL ratio, aneurysm diameter was significantly higher in above-median monocyte/HDL ratio group (54.3 +/- 10.6 mm vs 62.0 +/- 12.4 mm, p < 0.001, respectively). Hypertension, coronary artery disease, monocyte/HDL ratio and C-reactive protein were independently associated with AAA diameter. Conclusion: Monocyte/HDL ratio is independently associated with AAA size.
