Headache as a presentation of angina: reproduction of symptoms during angioplasty.

We report a case of angina presenting as headache in a 59-year-old man. Headaches were relieved by nitroglycerin and were reproduced by occlusion of the first obtuse marginal artery during angioplasty. Headaches resolved after successful angioplasty. The temporal relationship between coronary artery occlusion and the headache suggests that headache angina is due to referred pain rather than a generalized vasospastic disorder.
