Developmental changes in energy substrate use by the heart

Lopaschuk, G. D, Collins-Nakai, R. L, Itoi, T.·1992·Cardiovascular Research

Abstract

Marked changes in intermediary metabolism occur during development of the heart. In the fetus, the heart utilises lactate and glucose as its main energy substrates, while in the adult, fatty acids are the main energy substrate. The transition from carbohydrate to fatty acid metabolism is a complex process which involves maturation of mitochondrial processes and dramatic changes in circulating levels of fatty acids and lactate. In addition, developmental changes in the use of energy substrates also involve changes in the regulation of the enzymes involved in both carbohydrate and fatty acid utilisation. This paper reviews these changes in intermediary metabolism which occur during myocardial development. The metabolic differences that exist between immature and adult hearts may explain the observed differences in the ability of immature hearts to withstand hypoxaemia or ischaemia.

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.
