{Abstract}: Advanced atherosclerosis is linked to plaque instability, which can result in rupture and the onset of a heart attack. Evidence gathered from human atheroma plaques indicates that intraplaque neovascularization poses a risk to plaque stability and may lead to plaque hemorrhage. Hence, targeting the neovascularization within the atheroma plaque has the potential to mitigate the plaque's vulnerability. While neovascularization has been extensively explored in the context of cancer, research on pharmacological inhibition of this phenomenon in atherosclerosis remains limited. This systematic review aimed to comprehensively assess current and emerging pharmacological interventions for inhibiting intraplaque neovascularization in preclinical settings. Electronic databases (Web of Science, PubMed, Scopus, and Ovid) were searched from January 2013 until February 1, 2024. Preclinical studies reporting the effect of any pharmacological interventions targeting intraplaque neovascularization were included. A total of 10 articles involving in vivo animal studies were eligible for inclusion, with five of them incorporating in vitro experiments to complement their in vivo findings. The pharmacological interventions studied were axitinib, ghrelin, K5, rosuvastatin, atorvastatin, 3PO, everolimus, melatonin, Si-Miao-Yong-A, and protocatechuic aldehyde. All the interventions showed a positive impact in inhibiting intraplaque neovascularization in various atherosclerotic animal models through various signaling pathways. This review provides valuable insights into pharmacological approaches to attenuate intraplaque neovascularization that could serve as a promising therapeutic avenue to enhance plaque stability.
