A Novel Marker of Impaired Aortic Elasticity in Never Treated Hypertensive Patients: Monocyte/High-Density Lipoprotein Cholesterol Ratio

Acta Cardiol Sin. 2017 Jan;33(1):41-49. doi: 10.6515/acs20160427a.

Abstract

Background: Monocyte to high density lipoprotein cholesterol ratio (MHR) is generally understood to be a candidate marker of inflammation and oxidative stress. Therefore, we aimed to assess the association between MHR and aortic elastic properties in hypertensive patients.

Methods: A total of 114 newly-diagnosed untreated patients with hypertension and 71 healthy subjects were enrolled. Aortic stiffness index, aortic strain and aortic distensibility were measured by using echocardiography.

Results: Patients with hypertension had a significantly higher MHR compared to the control group (p < 0.001). Also, aortic stiffness index (p < 0.001) was significantly higher and aortic distensibility (p < 0.001) was lower in the hypertensive group. There was a positive correlation of MHR with aortic stiffness index (r = 0.294, p < 0.001) and negative correlation with aortic distensibility (r = -0.281, p < 0.001). In addition, MHR and high sensitivity C-reactive protein have a positive correlation (r = 0.30, p < 0.001). Furthermore, MHR was found to be an independent predictor of aortic distensibility and aortic stiffness index.

Conclusions: In patients with newly-diagnosed untreated essential hypertension, higher MHR was significantly associated with impaired aortic elastic properties.
