Abstract:
Objective To investigate the correlation analysis of serum autotaxin(ATX),tenascin-C(TN-C)and ventricular remodeling indexes in elderly patients with dilated cardiomyopathy(DCM)with heart fail-ure(HF)and their effects on prognosis.Methods 153 elderly patients with DCM with HF who were admit-ted to the 904th Hospital of the Joint Logistic Support Force from January 2020 to January 2022 were selected as DCM with HF group,and 100 elderly patients with simple DCM in the same hospital during the same peri-od were selected as DCM group and 100 healthy elderly individuals who underwent physical examination were selectedas control group.Serum ATX and TN-C levels were detected by enzyme-linked immunosorbent assay,and ventricular remodeling indexes[left ventricular end-diastolic diameter(LVEDD),left ventricular end-sys-tolic diameter(LVESD),and left ventricular ejection fraction(LVEF)]were detected by echocardiography.The correlation between serum ATX,TN-C levels and ventricular remodeling indexes in elderly patients with DCM with HF were analyzed by Pearson correlation analysis.Elderly patients with DCM with HF were fol-lowed up for 1 year,patients were divided into poor prognosis group and good prognosis group according to the prognosis.The influencing factors of poor prognosis in elderly patients with DCM with HF were analyzed by univariate and multivariate logistic regression analysis,the predictive value of serum ATX and TN-C levels for poor prognosis in elderly patients with DCM with HF was analyzed by receiver operating characteristic(ROC)curve.Results The serum levels of ATX and TN-C in DCM combined HF group were higher than those in DCM group and control group,and the difference was statistically significant(P＜0.05).Serum ATX and TN-C levels in DCM group were higher than those in control group,and the difference was statistically significant(P＜0.05).LVEDD and LVESD in DCM with HF group were higher than those in DCM group and control group,and LVEF was lower than those in DCM group and control group,the difference was statis-tically significant(P＜0.05).Pearson correlation analysis showed that serum ATX and TNC levels in elderly patients with DCM with HF were positively correlated with LVEDD and LVESD,and negatively correlated with LVEF(P＜0.05).Univariate analysis showed that HF disease course,NYHA cardiac function grade,NT-proBNP,ATX and TN-C were the influential factors for poor prognosis in elderly patients with DCM with HF(P＜0.05).Multivariate Logistic regression analysis showed that the independent risk factors for poor prognosis in elderly patients with DCM with HF were NYHA cardiac function grade≥Ⅲ and the increase of NT-proBNP,ATX and TN-C(P＜0.05).ROC curve analysis showed that the area under the curve and 95％CI of serum ATX and TNC alone and combined for poor prognosis in elderly patients with DCM with HF were 0.743(0.576-0.911),0.721(0.551-0.911)and 0.808(0.690-0.912),respectively.Conclusion The elevated levels of serum ATX and TN-C in elderly patients with DCM with HF may be relat-ed to ventricular remodeling and poor prognosis,and have certain predictive value for the prognosis of elderly patients with DCM with HF.
