Abstract:
Objective To explore whether brachial-ankle pulse wave velocity (baPWV) can be used as a predictor of recurrent cardiovascular events in elderly male patients with acute coronary syndrome (ACS). Methods The baPWV and biochemical indicators were measured in 118 elderly men with ACS, aged 61-92 years (mean age 76.6±6.7 years). During the follow-up period (617±297 days), all cardiovascular events (unstable angina, heart failure, cardiac death and stroke, etc.)were recorded. Results The baPWV was (17.48±3.54)m/s in non-event group(n=90),(21.91±4.86) m/s in event group and (24.48±4.39) m/s in major endpoint event group, respectively (both P＜0. 05). There were 30 cardiovascular events that occurred in 28 patients, including 12 major endpoint events. The receiver operating characteristic curve demonstrated that the cut-off point of baPWV for predicting a cardiovascular event was 19.51 m/s and that for predicting a major endpoint event was 20.52m/s. The multivariate Cox proportional hazards model demonstrated that the above cut-off points had significantly relative risk for cardiovascular event: 1.37(95% CI: 1.16-1.63)and for major event:1.71(95% CI: 1.23-2.36). Conclusions The baPWV can be used as a predictor of recurrent cardiovascular events in elderly men with ACS.
