BACKGROUND: Patients with chronic kidney disease (CKD) are associated with an increased risk of cardiovascular (CV) events. An increase in the ratio of the pre-ejection period (PEP) to ejection time (ET) is correlated with a decrease of left ventricular systolic function. Brachial PEP (bPEP) and brachial ET (bET) can be automatically determined from an ankle-brachial index (ABI)-form device. The aim of this study is to investigate whether bPEP/bET is a useful predictor for CV events in patients with CKD. METHODS AND RESULTS: We consecutively enrolled 242 CKD patients from our outpatient department of internal medicine. The bPEP and bET were measured using an ABI-form device. CV events were defined as cardiac death, stroke, myocardial infarction, and hospitalization for congestive heart failure. The study subjects were followed until the first episode of CV events occurred. The relative CV event risk was analyzed by Cox-regression methods. In the multivariate analysis, the presence of diabetes (hazard ratio (HR), 3.531; P=0.014), increased bPEP/bET (HR, 1.054; P=0.026), and decreased serum albumin level (HR, 0.525; P=0.005) were independent predictors for CV events. CONCLUSIONS: The study findings show that bPEP/bET is a useful predictor of CV events in CKD patients. Screening CKD patients by means of bPEP/bET might help to identify patients at high risk of increased CV events. |
