Correlation between GPR, MHR and elderly essential hypertension with unstable angina pectoris

To investigate the level and significance of serum γ-glutamyl transferase-to-platelet ratio (GPR) and monocyte count to high-density lipoprotein ratio (MHR) in patients with essential hypertension (EH) and unstable angina (UA).

A total of 218 patients with coronary angiography aged ≥60 years, who were admitted to the EH hospital of the Department of Cardiac Medicine, Affiliated Hospital of Chengde Medical College, were selected from September 2018 to September 2019. They were divided into an EH+UA group (n=113) and an EH group (n=105). In addition, 106 patients with normal coronary angiography who were diagnosed with coronary heart disease were selected as a control group. The general data, blood biochemical indicators, GPR and MHR in each group were compared, and partial correlation analysis and receiver operator characteristic (ROC) curve analysis were performed.

Compared with the control group, patients in the EH+UA group and the EH group had higher body mass index (BMI), tyiglyceride (TG), GPR, and MHR, and lower high-density lipoprotein-cholesterol (HDL-C) (all P<0.05); and patients in the EH+UA group had higher white blood cell counts, alanine aminotransferase (ALT), and uric acid (all P<0.05). Compared with the EH group, patients in the EH+UA group had higher GPR and MHR (both P<0.05). Partial correlation analysis showed that after controlling the antihypertensive drugs and lipid-lowering drugs, GPR was found to be positively correlated with BMI, white blood cell count, ALT, TG, and uric acid (r=0.160, 0.111, 0.205, 0.250, 0.154, respectively, all P<0.05), which was negatively correlated with HDL-C (r=-0.238, P<0.05); MHR was positively correlated with BMI, ALT, TG, uric acid, and GPR (r=0.186, 0.307, 0.157, 0.141, 0.223, respectively, all P<0.05), and negatively correlated with HDL-C (r=-0.610, P<0.001). ROC curve analysis showed that GPR had higher specificity and positive predictive value, while MHR had higher sensitivity. When the two indicators were combined, the sensitivity and positive predictive value were higher.

There is a correlation between GPR, MHR and EH combined with UA pectoris, and the combined detection of the two indicators has adjuvant diagnostic value for elderly EH combined with UA.
