The association between the monocyte-to-HDL cholesterol ratio and coronary collateral circulation in patients with chronic total occlusion

An elevated MHR is significantly associated with poor CCC development in patients with CTO. As a readily available and cost-effective biomarker, it has potential clinical utility for identifying patients at risk of insufficient arteriogenesis. Further prospective studies are needed to validate its prognostic utility and explore its therapeutic implications in ischemic heart disease.
