Abstract: Objective To study the relationship between the level of Rho-associated protein kinase 1 (ROCK1) in peripheral blood and vascular endothelial function and carotid intima-media thickness (IMT) in elderly patients with unstable angina pectoris (UA). Methods From June 2018 to June 2020, the elderly patients with suspected coronary heart disease in our hospital were selected and divided into UA group (with positive coronary angiography and diagnosis of UA) 74 cases and control group (with negative coronary angiography and no UA) 52 cases. Total cholesterol (TC), triglyceride (TG),high density lipoprotein-cholesterol(HDL-C), low density lipoprotein-cholesterol (LDL-C), uric acid, glycosylated hemoglobin (HbA1c) and other indicators were measured and compared in each group; Rock1 level in peripheral blood was detected by enzyme labeling method; flow mediated dilation(FMD) and IMT were measured and compared between the two groups. Pearson correlation was used to analyze the correlation between ROCK1 and parameters, and multiple linear regression was used to investigate the multiple factors. Results Except for smoking and HbA1c(P<0.05), there were no significant difference in gender, age, body mass index (BMI), diabetes, hypertension and blood lipid between the two groups (P>0.05). The level of FMD in UA group was lower than that in control group, while the level of IMT and ROCK1 in UA group was higher than that in control group (P<0.05). Multiple linear regression analysis showed that FMD (X4) and IMT (X5) were included in the regression equation, and ROCK1 (Y)=0.512X5-0.462X4+2.106. Conclusion There is a certain correlation between ROCK1 and endothelial function and IMT in elderly patients with UA.
