ABSTRACT

To explore influence of bisoprolol combined benazepril on ECG and left ventricular diastolic function in hypertensive patients with acute heart failure (AHF).Methods:A total of 124 hypertensive patients with AHF were randomly and equally divided into routine treatment group and combined treatment group (received biso‐prolol combined benazepril based on routine treatment ) ,both groups were treated for two months .Therapeutic effect ,ECG indexes ,left ventricular diastolic function indexes ,levels of heart failure and myocardial injury markers etc .before and after treatment were compared between two groups .Results: After two‐month treatment ,total ef‐fective rate of combined treatment group was significantly higher than that of routine treatment group (96. 77% vs. 82. 26%, P＝0.008) ;compared with routine treatment group ,there were significant reductions in QRS wave dura‐tion [ (103. 87 ± 9.70) ms vs.(94.12 ± 8. 93) ms] ,QTc duration [ (432.37 ± 33. 24) msvs .(418.96 ± 29. 64) ms] , plane QRS‐T angle [ (59.75 ± 26. 61)°vs.(48.19 ± 22.30)°] ,mitral annulus late diastolic peak flow velocity (Am) [ (12.84 ± 3.40) cm／svs .(11. 39 ± 3. 11) cm／s] ,plasma levels of N terminal pro brain natriuretic peptide [ (1. 20 ± 0.58) μg／L vs .(0. 75 ± 0.47) μg／L] ,carbohydrate antigen 125 [ (19.10 ± 9.24) U／ml vs.(13.93 ± 7.85) U／ml] ,galectin‐3 [ (4.72 ± 2. 25) μg／L vs .(3.28 ± 1. 65) μg／L] ,cardiac troponin I [ (1.93 ± 0. 97) μg／L vs.(1. 46 ± 0. 85) μg／L] ,and significant rise in mitral early／late diastolic peak flow velocity (E／A) [(1. 18 ± 0.30) vs.(1. 31 ± 0. 28)] and mitral annulus early diastolic peak flow velocity (Em) [ (12.90 ± 3. 76) cm／svs.(14. 49 ± 3.25) cm／s] in combined treatment group , P＜0. 05 or ＜0.01. There was no significant difference in incidence rates of ad‐verse reactions between two groups , P＞0.05 all.Conclusion:Bisoprolol combined benazepril possesses significant therapeutic effect on hypertensive patients with AHF ,and its improving effect on ECG indexes and left ventricular diastolic function is significant .
