Stacey RB, et al. – In this study, researchers assessed glucose levels as a risk factor for unrecognized myocardial infarctions (UMIs). Study participants included 4,355 older adults (aged ≥ 65 years) with available fasting glucose values. The investigators analyzed the link between glucose levels and UMI. Study participants with a history of coronary heart disease or UMI on initial electrocardiography were excluded from analysis. Over a 6-year mean follow-up period, they identified 459 UMIs. Participants with impaired fasting glucose levels were slightly more likely to experience a UMI vs those with normal fasting glucose levels. Overall, according to findings, fasting glucose status, especially values or levels in the diabetic range, predicted UMI during 6 years of follow-up in this study population. The investigators cautioned, however, that further studies are warranted to clarify the level of glucose that confers the greatest risk.
