RESUMO
Targeted cancer therapies have revolutionized the treatment of the disease in the past decade. The tyrosine kinase inhibitor (TKI) class of drugs is a widely used option for treating various cancers. Despite numerous advances, clinical and experimental studies have demonstrated the atherosclerosis-inducing properties of these drugs that can cause adverse cardiovascular events. TKIs also have an atherosclerosis-preventing role in patients with cancer through different mechanisms under various conditions, suggesting that specific drugs play different roles in atherosclerosis regulation. Given these contradictory properties, this review summarizes the outcomes of previously performed clinical and basic experiments and shows how the targeted effects of novel TKIs affect atherosclerosis. Future collaborative efforts are warranted to enhance our understanding of the association between TKIs and atherosclerosis.

Coronary calcification plays a major role as a key surrogate measure of plaque burden, providing powerful risk stratification and influencing preventive therapy. Depending on its location and density, microcalcifications may directly result in plaque rupture and adverse clinical events. Although macroscopic calcifications are frequently linked to advanced and stable plaques, the fact that a small number of thrombotic events are caused by plaques that possess a substantial amount of calcification should not be overlooked. Early and accurate assessment of calcium content in atherosclerotic plaques potentially enhances the identification of high-risk patients requiring preventive treatments. Non-invasive imaging allows for the visualization, detection, and quantification of calcific lesions, whereas intravascular imaging has the unique advantage of providing real-time and accurate information during calcium modification interventions. Simultaneously, emerging molecular imaging modalities aid in the investigation of calcification activity. This review summarizes advanced techniques for coronary artery calcification imaging, including their merits and limitations, in addition to their potential applications in both experimental and clinical settings.
