Selective serotonin reuptake inhibitors (SSRIs) may contribute to sudden cardiac death. Pathological heart changes, including fibrosis, were observed in chronic SSRI users, suggesting a potential causative role even at therapeutic doses.
Area of Science:
- Cardiology
- Pharmacology
- Forensic Pathology
Background:
- Drug use, including SSRIs, is linked to cardiovascular risks and sudden death.
- Understanding the cardiac effects of SSRIs is crucial for patient safety.
Purpose of the Study:
- To investigate the pathological cardiac changes associated with selective serotonin reuptake inhibitor (SSRI) use.
- To explore the potential role of SSRIs in sudden cardiac death.
Main Methods:
- Comparative study of 40 sudden death cases (20 SSRI users, 20 controls).
- Inclusion of citalopram and sertraline users.
- Comprehensive analysis including autopsy, histology, biochemistry, and toxicology.
Main Results:
- SSRI users exhibited interstitial, perivascular, and perineural fibrosis in the left ventricle myocardium.
- These pathological changes were observed even at therapeutic SSRI concentrations.
Conclusions:
- Findings suggest SSRIs may play a causative role in sudden cardiac death pathogenesis.
- Further research with larger cohorts is warranted to confirm these observations.
