Southern Medical Journal
|November 1, 1983
Summary
Tricyclic antidepressants may be associated with cardiomyopathy. Physicians should consider discontinuing these drugs if cardiomyopathy develops, especially due to ventricular fibrillation risks.
Area of Science:
- Cardiology
- Clinical Pharmacology
Background:
- Tricyclic antidepressants (TCAs) are widely prescribed for various conditions.
- Cardiomyopathy is a disease of the heart muscle.
Observation:
- Nine previous cases linked TCAs to cardiomyopathy.
- A patient developed cardiomyopathy after years of TCA use.
Findings:
- A potential association exists between tricyclic antidepressant use and cardiomyopathy.
- A definitive cause-and-effect relationship remains unproven.
Implications:
- Discontinue TCAs if cardiomyopathy develops.
- Exercise extreme caution when prescribing TCAs to patients with cardiomyopathy.
- Consider the risk of ventricular fibrillation in patients on TCAs with heart conditions.
