Stress-induced brain activity linked to chest pain in CAD patients

Key clinical point: Stress-induced frontal lobe activity was associated with self-reported angina symptoms in patients with heart disease.

Major finding: Any doubling in inferior frontal lobe activation led to an increase in angina frequency by 13.7 units at baseline (95% CI, 6.3-21.7; P = .008) and 11.6 units during follow-up (95% CI, 4.1-19.2; P = .01).

Study details: A study of 148 patients with stable coronary artery disease.

Disclosures: The study was supported by grants from the National Institutes of Health. The authors reported no potential conflicts of interest.
