The Claim

In healthy middle-aged adults, insulin stimulation enhances myocardial glucose uptake but does not increase myocardial blood flow, indicating that changes in perfusion are not necessary for insulin-mediated glucose transport 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.

How it works
1 study reviewed
In plain English

In healthy middle-aged people, insulin helps the heart take in more sugar for fuel, but it doesn't make more blood flow to the heart. That means the heart can get more sugar without needing more blood flow.

See the scientific wording

In healthy middle-aged adults, insulin stimulation does not increase myocardial blood flow despite enhancing myocardial glucose uptake, suggesting that perfusion changes are not required for insulin-mediated glucose transport in the heart.

What the research says

1 study

  1. Study: Insulin-Stimulated Myocardial Glucose Uptake and the Relation to Perfusion and the Nitric Oxide System

    The study shows that insulin helps the heart take in more sugar without increasing blood flow, just like the claim says.
