Abstract:
Objective: To observe changes of variation of red blood cell distribution width-coefficient (RDW-CV), levels of matrix metalloproteinase (MMP)-2, MMP-9 and tissue inhibitor of metalloproteinases (TIMP)-1 in patients with essential hypertension (EH) of different risk stratification.Methods: A total of 105 EH patients treated in our department from Oct 2015 to Sep 2016 were regarded as EH group.According to hypertension risk stratification, they were divided into low risk group (n=34), medium risk group (n=38) and high-and extremely high risk group (n=33).Another 105 subjects with corresponding age and gender were selected as healthy control group during the same period.RDW-CV, serum levels of MMP-2, MMP-9 and TIMP-1 were measured and compared among all groups.Multivariate Logistic regression analysis was used to analyze relationship among above indexes and hypertension.Results: Compared with healthy control group, there were significant rise in RDW-CV [(12.57±1.46) vs.(14.54±1.82)], serum levels of MMP-2 [(121.71±18.86)ng/ml vs.(155.43±40.81)ng/ml], MMP-9 [(109.72±21.80)ng/ml vs.(191.23±53.05)ng/ml] and TIMP-1 [(59.42±9.41)ng/ml vs.(83.64±15.82)ng/ml] in EH group, P<0.05 or <0.01.Compared with low risk group, there were significant rise in RDW-CV [(13.35±1.54) vs.(14.43±1.17) vs.(15.90±1.81)], serum levels of MMP-2 [(131.21±35.24) ng/ml vs.(152.16±33.15)ng/ml vs.(184.16±37.14)ng/ml], MMP-9 [(163.95±38.61) ng/ml vs.(198.70±43.52)ng/ml vs.(232.83±54.12)ng/ml] and TIMP-1 [(73.15±13.12)ng/ml vs.(83.78±10.22) ng/ml vs.(94.27±16.77)ng/ml] in medium risk group, high-and extremely high risk group, and those of high-and extremely high risk group were significantly higher than those of medium risk group, P<0.05 or <0.01.Multivariate Logistic regression analysis indicated that RDW-CV, MMP-2, MMP-9 and TIMP-1 were independent risk factors for hypertension (OR=2.248~2.725, P<0.05 or <0.01).Conclusion: RDW-CV,MMP-2,MMP-9 and TIMP-1 are independent risk factors for hypertension, active monitoring and intervention should be given for these risk factors.
