Is prolactin involved in the evolution of atherothrombotic disease

Cardiovascular diseases (CVDs) account for approximately 30% of all deaths globally. The most important cause of CVD is atherothrombosis, in other words, narrowing of the arteries as a result of the deposition of cholesterol and other lipoid substances within the arterial wall. Several endocrine disorders have been linked to this pathological state. Recent clinical and experimental studies have suggested that prolactin, a pleiotropic pituitary hormone, may potentially contribute to CVD, either through direct modulation of local cellular processes within atherosclerotic plaques/thrombi and/or through influencing conventional cardiovascular metabolic risk factors. However, the precise role of prolactin in the pathology of CVD remains largely unknown. Here, the authors speculate whether prolactin-lowering treatment may become a future therapeutic approach in patients with elevated prolactin levels and concomitantly presenting with coexisting vascular disease or a significantly elevated risk for premature ath...
