Many people have had a heart attack and don’t know it. A study of older people in Iceland finds that nearly twice as many had experienced a silent heart attack as had suffered one with all the medical bells and whistles. MRI scans revealed the hidden heart attacks better than standard testing by electrocardiography, or EKG, scientists report in the Sept. 5 Journal of the American Medical Association.
In a community based cohort of oler individuals, the prevalence of unrecognized myocardial infarction by cardiac magnetic resonance imaging was higher than the prevalence of recognized myocardial infarction and was associated with increased mortality risk. In contrast, UMI by electrocardiography was lower than that of RMI and not associated with increased mortality risk.
