The Claim
In healthy adults, inhibition of nitric oxide synthesis reduces myocardial blood flow but does not affect insulin-stimulated myocardial glucose uptake, indicating that nitric oxide–mediated vasodilation is not required for insulin to facilitate glucose uptake in the heart.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When the body can't make nitric oxide, blood flow to the heart drops, but the heart still takes in sugar normally when insulin is around — meaning nitric oxide isn't needed for insulin to help the heart use sugar.
See the scientific wording
Blocking nitric oxide synthesis reduces myocardial blood flow but does not alter insulin-stimulated myocardial glucose uptake in healthy adults, suggesting that nitric oxide–mediated vasodilation is not necessary for insulin to promote glucose uptake in the heart.
What the research says
1 studyThe study shows that even when a drug reduces blood flow to the heart by blocking nitric oxide, insulin can still help heart cells take in glucose — just like the claim says.
