The correlation of serum cartilage glycoprotein 39 and angiopoietin-like protein 3 levels with left ventricular dysfunction in elderly patients of coronary heart disease with heart failure / 中华老年医学杂志

ABSTRACT

Objective:To analyze the relationship of serum cartilage glycoprotein 39(YKL-40)and angiopoietin-like protein 3(ANGPTL3)with left ventricular dysfunction in elderly coronary heart disease(CHD)patients with heart failure(HF).Methods:The 84 elderly patients divided into group of CHD with HF, and 80 patients divided into group of CHD without HF treated in Shekou People's Hospital of Nanshan District, Shenzhen City from January 2018 to December 2019 were enrolled in this study.Evaluation of the left ventricular function meets the cardiac function classification standard of(NYHA). Serum YKL-40 and ANGPTL3 levels in all patients were detected.The relationships of serum YKL-40 and ANGPTL3 levels with the left ventricular dysfunction were analyzed in the two groups.Results:Serum levels of YKL-40 and ANGPTL3 were higher in the group of CHD with HF than in the group of CHD without HF[(81.24±6.32)μg/L vs.(69.33±5.89)μg/L, and(42.40±5.03)μg/L vs.(30.25±4.23)μg/L, t=12.469 and 16.700, both P<0.001]. Of 84 patients of CHD with HF assessed by NYHA heart function, 35 cases were in the mild group and 49 cases were in the severe group.Logistic regression analysis showed that the elevated serum level of serum YKL-40 and ANGPTL3 was positively correlated with the severity of left ventricular dysfunction in patients of CHD with heart failure( OR=1.548 and 1.854, P=0.002 and 0.001). The receiver operator characteristic(ROC)curve showed that the area under the ROC curve(AUC)of YKL-40, ANGPTL3 alone and the combined index in predicting left ventricular dysfunction in CHD with heart failure were >0.80, and the best predictive value could be obtained when the cut-off values of YKL-40 and ANGPTL3 were 79.535 μg/L and 40.805 μg/L, respectively. Conclusions:The elevated serum level of YKL-40 and ANGPTL3 may indicate the more severe left ventricular dysfunction in patients of CHD with heart failure.Early monitoring of serumYKL-40 and ANGPTL3 levels has an important clinical significance in guiding early prediction and intervention of left ventricular dysfunction in patients of CHD with heart failure.
