Association of ankle-brachial index and pulse wave velocity with stroke in Han, Uighur, and Kazakh population of Xinjiang

Abstract

To investigate the relationship between stroke and ankle-brachial index (ABI), pulse wave velocity (PWV) in Han, Uighur, and Kazakh populations of Xinjiang. Data was from the investigation of cardiovascular risk survey (CRS) program among different nationalities in Xinjiang from October 2007 to March 2010. A total of 14 618 samples aged over 35 with complete data dimension were surveyed. (1) There were 633 patients with stroke, including 258 Hans (4.48%), 247 Uighurs (5.18%), and 128 Kazakhs (3.13%). The incidence of stroke was significant different in the three ethnic groups (P < 0.001). (2) Compared to the Han population, the incidence of stroke was higher (OR = 1.304) in Uighur but lower (OR = 0.794) in Kazakh. (3) PWV was significant different between stroke and non-stroke patients. After adjustment for age, body mass index, systolic blood pressure, triglyceride, total cholesterol and other risk factors, the difference remained significant, indicating that PWV (OR = 1.001, P < 0.001) might associate with the occurrence of stroke. The results of this study showed that the incidence of stroke was significantly different in the three ethnic groups. PWV might associate with the occurrence of stroke.
