Abstract

Background: In utero exposure to hyperglycemia is becoming increasingly prevalent as the number of women entering pregnancy with type II diabetes, or developing gestational diabetes, increases. Both animal studies and epidemiologic investigations have found cardiovascular abnormalities in adult offspring of hyperglycemic mothers (OHM). Objective: We hypothesized that adult OHM would have abnormal cardiac function in vivo and increased susceptibility to ischemia. Methods: Pregnant rats were made diabetic on day 12 of gestation. Serum glucose was monitored twice daily and insulin provided to maintain serum glucose at 200–400 mg/dl. Offspring were fostered to normal mothers after birth. Adult OHM were studied at 8–10 months of age with echocardiography to assess in vivo cardiac function and isolated hearts to determine the response to ischemia. Results: Echocardiography found significant diastolic dysfunction in male OHM compared to male controls. In isolated hearts, baseline cardiac function and left ventricular compliance was significantly diminished in male OHM compared to controls. Ischemia caused a significant decline in heart function in controls and female OHM, while function in male OHM remained unchanged. Conclusions: Adult male OHM demonstrate programmed cardiac dysfunction. Given the growing number of pregnancies complicated by hyperglycemia, additional assessment of cardiac function of adults born to diabetic mothers may be warranted.

  • Fetal hypertrophic cardiomyopathy is a well-recognized feature of gestational diabetes mellitus, though it was believed that this resolved within a few months of birth.

    “Fetal hypertrophic cardiomyopathy is a well-recognized feature of GDM, though it was believed that this resolved within a few months of birth [78,79,80,81,82].”

    From Recent Experimental Studies of Maternal Obesity, Diabetes during Pregnancy and the Developmental Origins of Cardiovascular Disease (2022) · cites this paper as [80]

    The Introduction describes neonatal hypertrophic cardiomyopathy similar to that found in human offspring of diabetic mothers, supporting its association with maternal diabetes. The Discussion says that cardiac changes persisted into adulthood in the study’s rat model, but it does not say that human fetal cardiomyopathy was believed to resolve within a few months of birth.

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.
