Cardiotoxicity is the occurrence of heart electrophysiology dysfunction or muscle damage; that results in heart toxicity.[1] The heart becomes weaker and is not as efficient in pumping and therefore circulating blood. Cardiotoxicity may be caused by chemotherapy (a usual example is the class of anthracyclines)[2][3] treatment including radiotherapy;[4] complications from anorexia nervosa; adverse effects of heavy metals intake; the long-term abuse of or ingestion at high doses of certain strong stimulants such as cocaine; or an incorrectly administered drug such as bupivacaine.[citation needed]

One of the ways to detect cardiotoxicity at early stages when there is a subconical dysfunction is by measuring changes in regional function of the heart using strains.[citation needed]
