Medication-Induced Troponin Elevation
Cardiac troponin elevation can result from medication-related myocardial injury. Common high-yield drug classes include anticancer agents (anthracyclines, immune checkpoint inhibitors, and some other cardiotoxic cancer therapies). (jacc.org)
Anticancer Therapy
Anthracyclines
Anthracyclines (example: doxorubicin) are associated with troponin rise during or after chemotherapy and are linked to cardiotoxicity. (pmc.ncbi.nlm.nih.gov)
Immune checkpoint inhibitors
Immune checkpoint inhibitors (examples: PD-1 inhibitors such as nivolumab or pembrolizumab, and CTLA-4 inhibitors such as ipilimumab) can cause myocarditis and troponin elevation. (pmc.ncbi.nlm.nih.gov)
Other cancer therapies
Cardio-oncology expert panel recommendations describe that cardiac troponin elevation occurs in a substantial proportion of patients after exposure to cancer treatments, commonly including anthracyclines. (jacc.org)
Immunoglobulin and Hypersensitivity Reactions
Hypersensitivity drug reactions can cause myocardial injury patterns that include troponin elevation. (acc.org)
Toxic Substances with Cardiovascular Effects
Cocaine and methamphetamine are associated with ischemic myocardial injury mechanisms that can present with troponin elevation. (merckmanuals.com)
Medication-Associated Myocardial Injury Mechanisms
Medication-related troponin elevation can reflect necrosis or injury to cardiomyocytes. (pmc.ncbi.nlm.nih.gov)
Common Clinical Contexts Raising Pretest Probability
Troponin elevation during cancer therapy should increase suspicion for cancer therapy-related myocardial injury. (jacc.org)
Key Interpretation Considerations
Troponin elevations are not specific for acute coronary syndrome and can occur from multiple non-ACS etiologies, including medication-related myocardial injury. (jacc.org)
