ABSTRACT
Objective To investigate the relationship between serum stem cell factor receptor(c-kit)and myocardial fibrosis,cardiac function and prognosis in patients with dilated cardiomyopathy(DCM)complicat-ed with heart failure.Methods A total of 77 patients with DCM complicated with heart failure who were trea-ted in 3201 Hospital from May 2020 to June 2022 were enrolled in the study as study group,and 70 DCM pa-tients without heart failure were enrolled as the control group.The levels of serum c-kit mRNA and three my-ocardial fibrosis markers[α-smooth muscle actin(α-SMA),collagen type Ⅰ and collagen type Ⅲ]were detec-ted in the two groups.Cardiac function parameters were obtained by echocardiography.The relationship be-tween serum c-kit mRNA level and myocardial fibrosis and cardiac function was analyzed.According to the oc-currence of major adverse cardiovascular events(MACE),the patients were divided into poor prognosis group and good prognosis group.Multivariate Logistic regression analysis was used to analyze the factors affecting the prognosis of DCM patients complicated with heart failure.Receiver operating characteristic(ROC)curve was used to analyze the efficacy of serum c-kit mRNA level in predicting the prognosis of DCM patients.Results The serum c-kit mRNA level in the study group was lower than that in the control group(P<0.05).The levels of three myocardial fibrosis indicators in the study group were higher than those in the con-trol group(P<0.05).The left ventricular ejection fraction(LVEF)in the study group was lower than that in the control group(P<0.05),and the left ventricular end-diastolic volume(LVEDV)and left ventricular end-systolic volume(LVESV)in the study group were higher than those in the control group(P<0.05).Pearson correlation analysis showed that serum c-kit mRNA level was positively correlated with LVEF(r=0.677,P<0.05),while negatively correlated with α-SMA,collagen type Ⅰ,collagen type Ⅲ,LVEDV and LVESV(r=-0.725,-0.748,-0.744,-0.745,-0.662,P<0.05).Multivariate Logistic regression analysis showed that serum c-kit mRNA level is an independent factor for the prognosis of DCM patients with heart failure.ROC curve analysis showed that serum c-kit mRNA level had a sensitivity of 82.80%,a specificity of 81.80%,and an area under the curve of 0.829(95%CI0.745-0.912,P<0.001)for evaluating the progno-sis of DCM patients complicated with heart failure.Conclusion The serum c-kit mRNA level is significantly decreased in patients with DCM complicated with heart failure,and the serum c-kit mRNA level is correlated with myocardial fibrosis and cardiac function.The detection of serum c-kit mRNA level has a high efficacy in evaluating the prognosis of patients with DCM complicated with heart failure.
