New Study Demonstrates Possible Link Between Migraine Headaches and Heart Attacks
December 06, 2006 by
The results of a study presented at this week's 2006 Scientific Sessions of the American Heart Association has led to the discovery that menwith a history of migraine headache had a 24% increase in risk for major cardiovascular 
disease (CVD), primarily due to a 42% increase in the risk for myocardial infarction (MI, or "Heart Attack"). This finding parallels results reported earlier this year by the same team of investigators who found that women with a history of migraine with aura, or migraine with visual or neurologic disturbances occurring within 30 minutes prior to the onset of a migraine headache, were at a higher risk for MI or other cardiovascular conditions than women without migraine. Surprisingly, women who reported migraine without aura were not at an increased risk for CVD.
The study presented this week involved participants in the Physicians' Health Study who were free of outcome events at the start of follow-up. The men replied to yearly questionnaires and were asked about migraines, risk factors, and whether or not any study end point (MI or "heart attack", stroke, or other CVD) had occurred.
Over the 15.7 year follow-up period a total of 2,236 major cardiovascular events occurred. After adjustment for a variety of factors, the authors found a significantly increased risk for the development of major cardiovascular disease among migraine sufferers than men without migraine, most notably an increased risk for MI. However, no significant increase in the risk for ischemic stroke, coronary revascularization, angina, or ischemic cardiovascular death was seen among those with migraine when compared with those without migraine.
The authors of the report were quick to note that their investigation made no attempt to identify what the commonalities between migraine and CVD might be, if any, and emphasized that much more research remains to be done in this area.
