What are BNP Functions and Effects?
Understanding the functions and effects of BNP
Dyspnea i.e., trouble in breathing, is a hallmark symptom of heart failure. Several conditions such as lung, liver, or kidney disorders may also cause dyspnea. Scientists and researchers use the B type natriuretic peptide to confirm heart failure. Therefore, testing BNP levels by lab specialists is essential to confirm the underlying reasons for the symptoms.
The heart secretes b type natriuretic peptide or BNP in response to increased ventricular blood volume and pressure. This promotes natriuresis, diuresis, vasodilation, and decreases the central venous pressure and systemic vascular resistance. As BNP decreases the systemic vascular resistance, the blood pressure is decreased. Moreover, as the central venous pressure decreases, BNP eventually lowers the overall cardiac output. Cardiac muscles of the left ventricle secretes BNP, therefore high levels of BNP affect the functioning of the heart and may show left ventricular dysfunction.
