A heart failure index (NT-proBNP) of 35,000 is clinically considered a very severe form of heart failure, which can lead to life-threatening conditions such as sudden cardiac death, malignant arrhythmia, or shock. It may also be due to renal failure, which requires a combination of cardiac ultrasound and other tests to assess the severity of heart failure.
The heart failure index generally refers to the NT-proBNP level of patients with heart failure, and the criteria for diagnosing heart failure according to the NT-proBNP level vary according to the patient’s condition, as follows:
1. Patients with less than 300pg/ml are excluded from heart failure.
2. Patients less than 50 years old with NT-proBNP ≥ 450pg/ml, diagnose heart failure.
3. patients ≥50 years old, <75 years old, NT-proBNP ≥900pg/ml, diagnosis of heart failure.
4. Patient ≥75 years old, NT-proBNP ≥1800 pg/ml, diagnosis of heart failure.
5. NT-proBNP is mainly excreted through the kidneys, and patients with renal insufficiency often cause abnormal pseudo-elevation of NT-proBNP.
Therefore, when the patient’s natriuretic peptide level reaches 35000pg/ml, a specialist doctor is needed to combine the condition and other examination results to comprehensively determine the severity of the disease.
