Abstract

OBJECTIVE: To investigate the clinical value of platelet and inflammatory factor activation in vascular endothelial injury in hypertension. METHODS: A total of 120 hypertension patients diagnosed in our hospital from December 2019 to June 2021 were enrolled as study objects (Hypertension group); besides, another cohort of 60 healthy people undergoing physical examination at the same period were recruited as the controls (Control group). Next, the baseline clinical characteristics of subjects in the two groups were recorded and compared. Specifically, a hematology analyzer was adopt for detecting the mean platelet volume (MPV), platelet distribution width (PDW) and platelet hematocrit (PCT); ELISA for the level of IL-6, IL-8 and TNF-α; PHILIPS EPIQ 7 C (a device assessing endothelial vasodilator function in a non-invasive fashion) for reactive hyperemia index (RHI); univariate and multivariate regression analysis for risk factors triggering endothelial dysfunction; and Spearman correlation analysis for the correlation of platelet activation indicators and inflammatory factor level with vascular endothelial function. RESULTS: Compared with the Control group, the patients in the Hypertension group exhibited higher levels of MPV, PDW, PCT, inflammatory factors (IL-6, IL-8 and TNF-α) and lower RHI. Moreover, Spearman correlation analysis showed a significant negative correlation of MPV, PDW, PCT, IL-6, IL-8 and TNF-α level with RHI level. In addition, univariate and multivariate regression analysis presented that MPV, PCT, IL-8 and TNF-α were risk factors for vascular endothelial dysfunction. CONCLUSION: The activation of platelet and inflammatory factor is closely related to vascular endothelial function injury in patients with hypertension. To be specifically, platelet and inflammatory factor activation can effectively reflect the vascular endothelial function injury in patients with hypertension and has high clinical value.
