Troponin I in Alopecia Areata and Female Pattern Hair Loss

The study investigated serum levels of cardiac troponin I in 82 patients, including 29 with alopecia areata, 30 with female pattern hair loss, and 23 healthy controls. Results showed that patients with alopecia areata had significantly higher levels of cardiac troponin I compared to both the female pattern hair loss group and the control group, suggesting a potential link between alopecia areata and subclinical myocardial injury. No significant difference in troponin I levels was found between the female pattern hair loss group and the control group. The findings indicated that clinicians should consider cardiovascular comorbidities when diagnosing alopecia areata.
