Can cardiovascular drugs support cancer treatment? The rationale for drug repurposing.

Research on the concept of biological overlap between cardiovascular and oncological diseases is gaining momentum. In fact, in both conditions, the malfunction of common regulatory mechanisms, such as the renin-angiotensin system (RAS), sympathetic nervous system (SNS), coagulation cascade, sodium-potassium ATP-ases, and mevalonate pathway, occurs. Thus, targeting these mechanisms with well-known cardiology drugs, including angiotensin-converting enzyme inhibitors (ACE-Is), angiotensin receptor blockers (ARBs), β-adrenergic receptor blockers, statins, cardiac glycosides (CGs), and low-molecular-weight heparins (LMWHs), could be a novel, promising adjuvant strategy in cancer management. Thus, here we discuss the idea of repurposing cardiology drugs in oncology based on available preclinical and clinical data.
