• W2803038547 abstract "An increase in the ratio of the brachial pre-ejection period to brachial ejection time [pre-ejection period (PEP)/ET] is correlated with a decrease of left ventricular ejection fraction (LVEF). The current study was designed to test the hypothesis that the change value (Δ) of PEP/ET is a useful indicator of Δ LVEF in patients with left ventricular systolic dysfunction.We consecutively enrolled 104 patients with left ventricular systolic dysfunction (LVEF < 45%). PEP/ET, B-type natriuretic peptide (BNP), and LVEF were evaluated at baseline and at 6-month follow-up. Compared with the baseline measurements, the 6-month values of ΔLVEF, ΔBNP, and ΔPEP/ET were 9.8% ± 9.0% (from 36.3% ± 9.2% to 46.3% ± 12.5%, P < 0.001), -168.5 ± 255.4 (from 271.4 ± 282.5 to 104.1 ± 129.6, P < 0.001), and -0.060 ± 0.069 (from 0.413 ± 0.097 to 0.358 ± 0.079, P < 0.001), respectively. There were significant correlations between LVEF and PEP/ET and between LVEF and BNP in both the initial (r = -0.316, P = 0.001 and r = -0.598, P < 0.001, respectively) and 6-month follow-up (r = -0.307, P = 0.003 and r = -0.701, P < 0.001, respectively). The Steiger's Z test showed that BNP had a significantly stronger correlation with LVEF compared with the correlations between LVEF and PEP/ET in both the initial and 6-month studies (Z = 2.471, P = 0.013 and Z = 3.575, P < 0.001, respectively). There were also significant correlations between ΔLVEF and ΔPEP/ET (r = -0.515, P < 0.001) and between ΔLVEF and ΔBNP (r = -0.581, P < 0.001); however, there was no difference between the correlations for ΔLVEF and ΔPEP/ET versus ΔLVEF and ΔBNP (Steiger's Z = 0.600, P = 0.545).In patients with left ventricular systolic dysfunction not only ΔBNP but also ΔPEP/ET could be a simple indicator of predicting change of LVEF." @default.
