Heart Failure 46,000 indicates that the patient’s NT-proBNP value is 46,000 pg/L, which indicates the presence of a heart failure problem, but does not reflect a specific heart failure grade, as heart failure grading is based on the New York Cardiac Function Classification Criteria. There are two commonly used indicators of heart failure, one is the ejection fraction in cardiac ultrasound, and the other is the NT-proBNP indicator in blood tests, of which the latter refers to the human brain natriuretic peptide index, and the normal value of this indicator is 100 pg/L. If the actual value reaches 500 pg/L, it is not a reflection of the specific heart failure grade. If the actual value is 500 pg/L or more, then heart failure may be present, and the higher the NT-proBNP level, the more severe the heart failure. If the NT-proBNP index reaches 46,000 pg/L, then it indicates the presence of severe heart failure. However, the number of grades of heart failure is based on the New York Heart Function Classification Standard, and has no direct relationship with the value of the NT-proBNP index, so the heart failure 46,000pg/L does not indicate the exact number of grades. In order to judge the grading of heart failure, then it is necessary to combine the specific symptoms of the patient to analyze, so it is recommended that the patient go to the hospital in time for examination, with the help of the doctor to grade it, so as to provide help for the subsequent treatment.
