Due to its wider physiological effects, the Prolactin (PRL) test, which is commonly used to evaluate pituitary and reproductive function, is also used in health heart diagnostics (HHD). The pituitary gland produces the hormone prolactin, which mostly affects how much milk nursing mothers produce. Prolactin levels can affect cardiovascular health as well as other systemic impacts outside of reproductive activities.
Hyperprolactinemia, a disorder marked by elevated prolactin levels, can affect the cardiovascular system indirectly in a number of ways. For example, metabolic disorders such as obesity and insulin resistance, which are established risk factors for cardiovascular disease, have been linked to elevated prolactin levels. Furthermore, prolactin may affect endothelial function, which is essential for preserving arterial health, hence influencing vascular health.
