Objective To investigate the change of cardiac structure and function in patients with uremia before and after peritoneal dialysis (PD). Methods Eighty three standard continuous ambulatory peritoneal dialysis (CAPD) patients treated between October 2009 and October 2014 were selected in this study. According to the ultrasound cardiogram before and 6 months after the PD, we analyzed the influence of age, diabetes mellitus, dialysis interval, hemoglobin, serum albumin, serum creatinine, serum calcium and phosphate and parathyroid hormone (PTH) on the cardiac structure and function. Results Hemoglobin increased significantly after PD (P <0.01), while albumin and PTH decreased significantly (P <0.01). The changes in creatinine, triglyceride and cholesterol were not statistically significant (P > 0.05). For CAPD patients, cardiac systolic function did no t obviously change before and after dialysis, while the diastolic function improved obviously after dialysis. Conclusion PD may improve cardiac diastolic function of CAPD patients.
ObjectivesTo systematically review the efficacy of Qiliqiangxin capsule on cardiac function in patients with heart failure with preserved ejection fraction (HFpEF).MethodsCNKI, VIP, WanFang Data, CBM, EMbase, PubMed and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) of Qiliqiangxin capsule for HFpEF from inception to August 1st, 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was performed by RevMan5.3 software.ResultsA total of 24 RCTs involving 2 021 patients were included. The results of meta-analysis showed that Qiliqiangxin capsule combined with conventional western medicine could improve E/A wave ratio (MD=0.17, 95%CI 0.13 to 0.21, P<0.000 01), reduce E/e' wave ratio (MD=−2.16, 95%CI −3.23 to −1.08, P<0.000 1), BNP (MD=−240.43, 95%CI −357.66 to −123.20, P<0.000 1), and NT-proBNP (MD=−200.64, 95%CI −290.02 to −111.27, P<0.000 1). However, there were no statistically significant differences between two groups in re-hospitalization rate (RR=0.57, 95%CI 0.27 to 1.19, P=0.13), mortality (RR=0.33, 95%CI 0.04 to 3.05, P=0.33), and incidence of adverse events (RR=0.59, 95%CI 0.26 to 1.34, P=0.20).ConclusionsThe present evidence shows that Qiliqiangxin capsule combined with conventional western medicine can improve neuroendocrine disorders and cardiac structure in patients with HFpEF, and further improve cardiac diastolic function. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo systematically review the efficacy and safety of Xinmailong injection in the treatment of different types of heart failure with ejection fraction.MethodsCNKI, WanFang Data, VIP, CBM, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) of Xinmailong injection in the treatment of different types of heart failure with ejection fraction from inception to August 5th, 2020. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 25 RCTs involving 2 467 patients were included. The results of meta-analysis showed that Xinmailong injection combined with conventional therapy was superior to conventional therapy alone on NYHA classification efficiency (HFrEF: RR=1.32, 95%CI 1.04 to 1.69, P=0.02), comprehensive clinical efficacy (HFrEF: RR=1.24, 95%CI 1.15 to 1.34, P<0.000 01; HFpEF: RR=1.22, 95%CI 1.15 to 1.30, P<0.000 01), score of life quality (HFrEF: MD=−7.08, 95%CI −9.34 to −4.82, P<0.000 01), left ventricular ejection fraction (HFrEF: MD=4.99, 95%CI 3.18 to 6.80, P<0.000 01; HFpEF: MD=5.10, 95% CI 0.62 to 9.58, P=0.03), the level of B-type natriuretic peptide (HFrEF: SMD=−0.96, 95%CI −1.36 to −0.56, P<0.000 01; HFpEF: SMD=−1.83, 95%CI−2.35 to −1.31, P<0.000 01), the level of N-terminal pro-B natriuretic peptide (HFrEF: SMD=−2.98, 95%CI −4.45 to −1.51, P<0.000 1), and 6-minute walking distance (HFrEF: MD=52.56, 95%CI 34.22 to 70.90, P<0.000 01). There was no significant difference in drug-related adverse reactions between two groups.ConclusionsCurrent evidence shows that Xinmailong injection combined with conventional therapy have good efficacy and safety in the treatment of heart failure with different ejection fractions. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
