B-type natriuretic peptide (BNP) is a small protein secreted by the ventricles of the heart in response to excessive stretching of the heart muscles cells (myocytes). BNP is secreted into the blood when your heart is working hard.
The level of BNP is elevated in people with heart failure and left ventricular dysfunction. B-type natriuretic peptide blood levels correlate with both the severity of symptoms and the prognosis in congestive heart failure.
This blood test is a useful marker of heart disease risk, even in people with no clinical evidence of cardiovascular disease. High blood levels of BNP predict the risk for heart failure, first cardiovascular events, atrial fibrillation, and stroke.
You can check your B-type natriuretic peptide blood level with or without fasting. Take all medications as prescribed. Do not take your supplements the morning of the test.
