RESUMO
Objective:To compare the efficacy of sakubatril valsartan and valsartan in the treatment of patients with chronic cardiac insufficiency and the influence on zinc finger protein A20 and nuclear factor-κB (NF-κB) in peripheral bloodmononuclear cells (PBMCs).Methods:Ninety-senven patients with chronic cardiac insufficiency admitted to the Affiliated Hospital of Jining Medical College from February 2019 to January 2020 were continuously selected and randomly divided into the control group (48 cases) and the observation group (49 cases). Both groups received routine anti-heart failure according to the guidelines. The control group added with valsartan and the observation group added with sakubatril valsartan treatment. Before the treatment and after 3 months of treatment, the changes of cardiac function indexes and the changes of inflammatory markers such as hypersensitive C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α), matrix metalloproteinase 9 (MMP-9), and N-terminal pro B-type natriuretic peptide (NT-proBNP) were compared. PBMCs was extracted to detect zinc finger protein A20 and NF-κB levels. The incidence of adverse reactions in the two groups was recorded, and the relationship between zinc finger proteins A20, NF-κB and the myocardial injury marker NT-proBNP were analyzed.Results:After 3 months of treatment, the changes of cardiac function indexes in the observation group were better than those in the control group and the levels of hs-CRP, TNF-α, MMP-9, NT-proBNP in the observation group were lower than those in the control group: (1.96 ± 0.57) mg/L vs. (2.87 ± 0.79) mg/L, (7.11 ± 1.46) μg/L vs. (8.24 ± 1.57) μg/L, (110.14 ± 10.63) μg/L vs. (129.52 ± 17.96) μg/L, (716.91 ± 105.78) ng/L vs. (965.25 ± 97.41) ng/L, there were statistical differences ( P<0.05). After 3 months of treatment, the levels of finger protein A20, NF-κB in the observation group were lower than those in the control group: (3.57 ± 1.13) % vs. (4.41 ± 1.32) %, (29.87 ± 6.58) ng/L vs. (35.71 ± 10.02) ng/L, there were statistical differences ( P<0.05). Finger protein A20 and NF-κB in patients with chronic cardiac insufficiency were positively correlated with NT-proBNP ( r = 0.487, 0.738, P<0.01). Conclusions:On the basis of conventional treatment, compared with valsartan, the addition of sakubatril valsartan, can improve the cardiac function of patients with chronic cardiac insufficiency, reduce the body′s inflammatory response, reduce the expression of myocardial injury marker NT-proBNP, inhibit the activation of PBMCs NF-κB, and reduce the level offinger protein A20.
RESUMO
Objective:To analyze the application value of sakubatril valsartan in the treatment of chronic heart failure (CHF) based on cardiopulmonary test system.Methods:One hundred and thirty-five CHF patients admitted to the Affiliated Hospital of Jining Medical Collegefrom January 2019 to August 2020 were divided into the observation group (67 cases) and the control group (68cases) by random number table method. Both groups were treated with bisoprolol. The observation group was treated with the combination of sakubatril valsartan, and the control group was treated with the combination of benapril. The efficacy and cardiac function indicators of the two groups were compared. The cardiopulmonary exercise test system was used to measure the patient′s maximum exercise time (Tmax), maximum exercise Watt (Wmax), peak volume oxygen (Peak VO 2) and volume of anaerobic threshold oxygen (VO 2AT), and the incidence of adverse reactions were calculated. Results:The total effective rate in the observation group was higher than that in the control group: 92.54% (62/67) vs. 77.94%(53/68), the difference was statistically significant ( χ2 = 5.70, P<0.05). After the treatment, the levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) and soluble ST2 (sST2) in the observation group were lower than those in the control group: (2 000.47 ± 517.85) ng/L vs. (2 777.39 ± 812.49) ng/L, (0.33 ± 0.10) μg/L vs. (0.37 ± 0.09) μg/L, and the left ventricular ejection fraction (LVEF) was higher than that in the control group: (8.12 ± 6.44)% vs. (41.93 ± 6.73)%, the differences were statistically significant ( P<0.05). After the treatment, the left ventricular end-diastolic diameter (LVEDd), left ventricular end-systolic diameter (LVEDs), left ventricular mass index (LVMI), left atrial volume index (LAVI) in the observation group were lower than those in the control group: (55.47 ± 6.93) mm vs. (62.00 ± 7.18) mm, (37.14 ± 6.36) mm vs. (41.35 ± 6.43) mm, (136.76 ± 7.13) mg/m 2 vs. (140.98 ± 7.47) mg/m 2, (28.23 ± 2.59) ml/m 2 vs. (31.98 ± 2.17) ml/m 2; the Tmax, Wmax, PeakVO 2 and VO 2AT in the observation group were higher than those in the control group: (619.08 ± 65.36) s vs. (58.70 ± 52.44) s, (142.96 ± 16.05) W vs. (124.19 ± 13.38) W, (20.00 ± 5.74) ml/(min·kg) vs. (18.13 ± 3.58) ml/(min·kg), (13.89 ± 3.69) ml/(min·kg) vs. (11.23 ± 2.36) ml/(min·kg), the differences were statistically significant ( P<0.05). However, there was no statistically significant in the incidence of adverse reactions between the two groups ( P>0.05). Conclusions:Sakubatril valsartan in the treatment of CHF can not only optimize the efficacy and improve cardiac function, but also benefit cardiac exercise rehabilitation of patients, and not increase the safety risk.
