ABSTRACT
<p><b>OBJECTIVE</b>The study was designed to explore the value of the New York University Pediatric Heart Failure Index (NYU PHFI) for diagnosing and grading chronic heart failure in children.</p><p><b>METHODS</b>Totally 105 children with chronic heart failure or structural heart disease but without signs and symptoms of heart failure were enrolled. They were diagnosed using modified Ross score, NYU PHFI and NT-proBNP, respectively. According to modified Ross score as the referent criteria, the diagnostic value of NYU PHFI in quantifying chronic heart failure severity in children was studied. Furthermore, according to the grading of heart failure using modified Ross score, the area under the ROC curves of NYU PHFI was examined, respectively, in order to find out the optimal cut-off point.</p><p><b>RESULTS</b>NYU PHFI score was positively correlated with the modified Ross score (r = 0.909, P = 0.000). According to modified Ross score, NYU PHFI scores in different severity of heart failure in children differed significantly (F = 80.034, P = 0.000). A significantly positive correlation was found between plasma NT-proBNP and modified Ross score, and between NT-proBNP and NYU PHFI score. Correlation coefficients between plasma NT-proBNP and modified Ross score, and between plasma NT-proBNP and NYU PHFI score were 0.752 and 0.918, respectively. The correlation between NYU PHFI and plasma NT-proBNP was superior to that between modified Ross score and plasma NT-proBNP. According to modified Ross scores of 0 - 2 as being without heart failure, 3 - 6 as mild degree of heart failure, 7 - 9 as moderate degree of heart failure and 10 - 12 as severe degree of heart failure, the areas under the ROC curve of the NYU PHFI diagnosing if heart failure was present, differentiating moderate from mild and severe from moderate heart failure were 0.982, 0.942 and 0.918, respectively, and the sum of sensitivity and specificity was favorite when 6, 10 and 13 scores were set as cut-off value diagnosing the presence of heart failure, differentiating moderate from mild, and severe from moderate heart failure, respectively. According to above classification of heart failure based on NYU PHFI score, plasma NT-proBNP concentration was significantly different in different degree of heart failure (F = 53.31, P < 0.001). Plasma NT-proBNP concentration in those without heart failure was significantly lower than that of mild heart failure, and it was also significantly lower in mild heart failure than that of severe heart failure.</p><p><b>CONCLUSION</b>NYU PHFI was highly valuable for diagnosing chronic heart failure in children and 0 - 6 scores as being without heart failure, 7 - 10 scores as mild degree, 11 - 13 scores as moderate degree and 14 - 30 scores as severe degree of heart failure could be used as the reference criteria of different severities of heart failure.</p>
