Overall, in this follow-up study of HF children using sacubitril/valsartan, post-operative CHD patients showed significant improvement in echocardiographic LVEF, NT-proBNP levels, NYHA classes and catch-up growth, while CM-induced HF patients demonstrated significant improvement in LVEF and BSA normalized LVdd and LVds. Here, NPPB is linked to coronary artery disorder.
