Study on the correlation of waist-to-height ratio and triglyceride with cerebrovascular hemodynamics and stroke / 公共卫生与预防医学

ABSTRACT

Objective To explore the correlation of waist-to-height ratio (WHtR) and triglycerides (TG) with changes in cerebral hemodynamic index (CVHI) and the risk of stroke. Methods From March 2018 to March 2019, a total of 500 medical examinees were selected from the civil servants who underwent a physical examination in the physical examination department of our hospital. According to the TG level, the subjects were divided into two groups HTG group (208 cases) and normal group (292 cases). According to WHtR value, the subjects were divided into an abnormal group (216 cases) and a normal group (284 cases). According to the test results, CVHI and other information the stroke risk was analyzed among the 4 groups. Results The right Vmax and bilateral Qmean, Vmean, Vmin, and Dp in the HTG group were significantly lower than those in the normal group (P<0.05), while the bilateral Wv, Zcv, Rv, DR, and Cp were higher than those in the normal group (P<0.05). The parameters of bilateral Vmax, Qmean, Vmean, Vmin, and Dp in the abnormal group were significantly lower than those in the normal group (P<0.05), while the bilateral Wv, Zcv, Rv, DR, and Cp were higher than those in the normal group (P<0.05). The CVHI scores of the HTG group and the abnormal group were lower than those of the normal group (P<0.05), and the FSP scores were higher than those of the normal group (P<0.05). The proportion of high-risk strokes with CVHI<75 and FSP score ≥10 in the HTG group were both higher than that in the normal group (P<0.05). There were 4 predictors including HTG, WHtR, CVHI score, and FSP score. There was a statistically significant difference in the etiology of stroke between CVHI and FSP (P<0.05). The risk of stroke in patients with abnormal WHtR increased by 2.746 times, and the relative risk of stroke in patients with CVHI<75 increased by 3.298 times. Conclusion WHtR abnormality and CVHI<75 were two independent predictors of stroke risk. HTG may increase the risk of stroke by affecting cerebral hemodynamic indicators.
