[Evaluation of Criterion Validity of CHF-Quality of Life Scale of Integrative Medicine].

Abstract

Objective To evaluate the criterion validity of Chronic Heart Failure (CHF) -Quality of Life (QOL) Scale of Integrative Medicine (abbreviated as Scale). Methods Clinical data of 249 CHF in- patients were collected. Using Pearson and Spearman correlation analyses, the indicators such as NT- proBNP, cardiac function classification (NYHA) , 6 Minutes Walk Test (6MWT) , left ventricular ejection fraction (LVEF) were taken as exterior contrasts of standard validity, the correlation between the Scale and physicochemical indices of modern medicine were analyzed. The standard validity of the Scale was evaluated. Results Compared with before treatment, the numerical value of the overall index score of the Scale, LVEF, LVEF≤40%, and 6MWT all increased (P <0. 05, P <0. 01) ; NT-proBNP level decreased (P <0. 01). The numerical value of the overall index score of the Scale was negatively correlated with NY- HA classification and NT-proBNP level, but positively correlated with LVEF and 6MWT, all with statistical difference (P <0. 01). NT-proBNP, 6MWT, and NYHA classification were all correlated with the scores of the Scale in each field (P <0. 05). LVEF was correlated with the scores of the Scale in each field (P < 0. 05) except social function. Conclusion The Scale had favorable criterion validity, which could be taken as an indicator for comprehensive curative effect evaluation system of CHF.
