Heart hormones are substances produced by the heart that act as chemical messengers to regulate various bodily functions. These hormones play a crucial role in cardiovascular health, influencing blood pressure, fluid balance, and overall heart function. Some of the most well-known heart hormones include:
- Atrial Natriuretic Peptide (ANP): Secreted by the heart's atria, ANP helps lower blood pressure by promoting sodium and water excretion from the body.
- Brain Natriuretic Peptide (BNP): BNP is produced in the ventricles of the heart and works similarly to ANP, contributing to blood pressure regulation.
- C-type Natriuretic Peptide (CNP): CNP is primarily found in the brain and is involved in regulating vascular tone and blood flow.
These heart hormones are essential for maintaining cardiovascular homeostasis and play a vital role in regulating blood pressure, fluid balance, and overall heart health. Their levels can be used as diagnostic markers for conditions such as heart failure.
