Significant correlation between ratio of brachial pre-ejection period to ejection time and left ventricular ejection fraction and mass index in patients with chronic kidney disease

Patients with chronic kidney disease (CKD) are associated with increased cardiovascular morbidity and mortality. An increase in the ratio of pre-ejection period (PEP) to ejection time (ET) is correlated with an increase in left ventricular mass index (LVMI) and a decrease in left ventricular ejection fraction (LVEF). Brachial PEP (bPEP) and brachial ET (bET) can be automatically determined by an ankle-brachial index (ABI)-form device. The aims of this study were to assess whether bPEP/bET is a useful parameter in evaluation of LVMI and LVEF in patients with CKD and to evaluate the diagnostic value of bPEP/bET in the prediction of LVEF
