The prevalence of unrecognised heart attacks among older adults could be higher than previously thought, a study published in the Journal of the American Medical Association has suggested.
Researchers from the National Institutes of Health, in Bethesda, USA, examined MRI data from 936 people aged between 67 and 93-years-old, including 670 who were randomly selected and 266 with diabetes.
The median age was 76 years, and 52% of the participants were women.
A total of 91 of 936 participants –9.7% - had a recognised myocardial infarction and the prevalence of an unrecognised MI was 17%, or 157 people.
Those with diabetes had a higher prevalence of unrecognised heart attacks at 21% or 72.
