Abstract

OBJECTIVE—Individuals with diabetes have an increased morbidity from acute myocardial infarction (AMI). Based on an oral glucose tolerance test (OGTT), 40–45% of patients with AMI have diabetes. The objective of this study was to characterize the glucometabolic profile of patients with AMI without known diabetes and to see if sustained glucometabolic perturbations are predictable during the hospital phase of the disease. RESEARCH DESIGN AND METHODS—A total of 145 patients with AMI and no previous diagnosis of diabetes were subjected to an OGTT at hospital discharge and 3 months thereafter. Based on the OGTT after 3 months, they were defined as having normal glucose tolerance (NGT; n = 50), impaired glucose tolerance (IGT; n = 59), or diabetes (n = 36). Components of the metabolic syndrome, including insulin resistance assessed by homeostasis model assessment (HOMA-IR), were recorded. RESULTS—Patients with AMI had no changes in insulin resistance from hospital discharge to follow-up. An OGTT and/or a single blood glucose taken 60 min (BG-60) after ingestion of 75 g glucose at hospital discharge were predictors of the outcome of the OGTT at follow-up. With a cutoff value for BG-60 of 8.6 mmol/l, 70% of the patients were correctly predicted as either belonging to the NGT group or the IGT/diabetes group after 3 months. Age, BMI, antihypertensive treatment, HbA1c, fasting blood glucose, blood lipids, insulin, proinsulin, HOMA-IR, and plasminogen activator inhibitor 1 did not add predictive power. CONCLUSIONS—Patients with AMI and no previous diagnosis of diabetes have no changes in insulin resistance from hospital discharge to a 3-month follow-up. An OGTT or a single BG-60 performed at hospital discharge predicts the diagnosis of IGT or diabetes 3 months thereafter.

  • A recent study suggested that most patients newly diagnosed with diabetes mellitus during hospitalization for acute coronary syndrome continue to have increased glucose levels after 3 months.

    “a recent study has suggested that most patients who have DM that is newly diagnosed during hospitalization for ACS continue to have increased glucose levels after 3 months.5”
  • Patients with diabetes mellitus or the metabolic syndrome are at markedly higher risk for recurrent cardiovascular events after acute coronary syndrome.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
