Abstract
A 67-year-old male smoker had exertional headaches for 2 years. The headaches were holocephalic, very severe, excruciating, and occasionally accompanied by nausea. Physical examinations and neuroimaging were normal. Electrocardiogram (ECG) showed old infarct in inferior leads. Sublingual nitrate provided relief in headaches. Stress test was positive with recurrence of similar headaches with ECG changes suggestive of myocardial ischemia. Coronary angiogram revealed three-vessel disease. Coronary artery bypass surgery provided complete resolution of headaches.
