ABSTRACT
Objective:
This study aimed to systematically evaluate the efficacy and safety of ivabradine in patients with dilated cardiomyopathy, and to provide evidence-based reference for clinical treatment.Methods:
We searched PubMed, Embase, Cochrane Library, Web of Science, CNKI, Wan Fang, VIP databases from inception to 1 September 2021 for randomized controlled trials (RCTs) that compared conventional therapies and ivabradine with conventional therapies in dilated cardiomyopathy patients. Studies meeting the inclusion criteria were included and analyzed. After data extraction and literature quality evaluation, we use the Review Manager 5.4 to perform the meta-analysis and publication bias test.Results:
5 studies enrolling 494 patients were included. Compared with conventional therapies (control group), ivabradine and conventional therapies (observation group) significantly reduced resting heart rate [ MD=-7.58, 95% CI(-12.40, -2.76), Z=3.08, P=0.002], left ventricular end diastolic diameter (LVEDD) [ MD=-4.48, 95% CI(-7.33, -1.64), Z=3.09, P=0.002], left ventricular end systolic diameter (LVESD) [ MD=-4.94, 95% CI(-7.29, -2.59), Z=4.12, P<0.001], B-type natriuretic peptide (BNP) [ MD=-212.39, 95% CI(-230.55, -194.23), Z=22.92, P<0.001], New York Heart Association (NYHA) class [ MD=-0.36, 95% CI(-0.44, -0.27), Z=8.46, P<0.001] and Minnesota Questionnaire Score [ MD=-10.43, 95% CI(-15.72, -5.13), Z=3.86, P=0.001]. The left ventricular ejection fraction (LVEF) levels [ MD=1.31, 95% CI(0.64, 1.97), Z=3.85, P=0.001], 6-minute walk test level (6MWT) [ MD=54.83, 95% CI(40.58, 69.08), Z=7.54, P<0.001], systolic blood pressure [ MD=4.72, 95% CI(0.91, 8.54), Z=2.43, P=0.02], the incidence of visual symptoms (phosphene) [ OR=7.22, 95% CI(1.32, 45.00), P=0.02] and symptomatic bradycardia [ OR=8.90, 95% CI(1.21, 65.75), P=0.03] in the observation group were higher than those in the control group after treatment. In addition, there were no significant difference in the incidence of acute event between the two groups [ OR=0.72, 95% CI(0.12, 4.29), P=0.72].Conclusions:
Meta analysis showed that ivabradine combined β receptor blockers can effectively reduce resting heart rate and improve cardiac function in patients with dilated cardiomyopathy, but may increase the incidence of hallucinations and symptomatic bradycardia.
