However, some evidences suggest potential associations between CMD and multiple extracardiac pathologies, such as cerebrovascular, renal, pulmonary, retinal, hepatic, immune system diseases, and cancer. A shared pathological mechanism may underlie these connections, yet the relationship between CMD and other organs and systemic diseases remains unclear. Therefore, this review comprehensively assesses the current evidence base for the interplay between CMD and a range of systemic diseases, highlighting the need for a more integrated diagnostic and therapeutic approach.
