Key result
Simvastatin improves postprandial endothelial dysfunction by reducing oxidative stress from combined hypertriglyceridemia and hyperglycemia.
Why the study?
The independent and cumulative effects of postprandial hypertriglyceridemia and hyperglycemia on endothelial dysfunction and oxidative stress were not fully understood.
Does simvastatin improve endothelial dysfunction and oxidative stress associated with postprandial hypertriglyceridemia and hyperglycemia?
Does simvastatin improve endothelial dysfunction and oxidative stress associated with postprandial hypertriglyceridemia and hyperglycemia?
Simvastatin may mitigate endothelial dysfunction and oxidative stress caused by the cumulative effects of postprandial hypertriglyceridemia and hyperglycemia.
Answers are grounded in this paper and cite their sources.
Simvastatin attenuates postprandial endothelial dysfunction from hypertriglyceridemia and hyperglycemia; extends evidence for statin vascular benefits beyond lipid lowering.
This study shows an independent and cumulative effect of postprandial hypertriglyceridemia and hyperglycemia on endothelial function, suggesting oxidative stress as common mediator of such effect. Simvastatin shows a beneficial effect on oxidative stress and endothelial dysfunction, which may be ascribed to a direct effect as well as the lipid-lowering action of the drug.

Ceriello et al. (2002) studied this question. Postprandial hypertriglyceridemia and hyperglycemia have an independent and cumulative effect on endothelial function mediated by oxidative stress, which is improved by simvastatin.
