Growth hormone-releasing hormone (GHRH) is a crucial endocrine hormone that exerts its biological effects by binding to specific receptors on the cell surface, known as GHRH receptors (GHRH-R). This binding activates downstream signaling pathways. In addition to promoting growth hormone secretion by the pituitary gland, GHRH also functions to maintain multisystem homeostasis by interacting with peripheral tissues that express GHRH-R. Due to the multiple roles of GHRH in body development and tissue repair, a variety of GHRH analogue peptides have been synthesized. Based on their effects on GHRH-R, these GHRH analogues can be classified as GHRH-R agonists and antagonists. Recently, the interaction of GHRH and its analogues with blood vessels, such as promoting angiogenesis and inhibiting vascular calcification (VC), has gained significant attention. This article reviews the effects of GHRH and its analogues on blood vessels.
