- Evidence summary
- A large body of good quality randomised controlled data shows consistently that physical activity improves vascular endothelial function (1-8) by improving nitric oxide production and attenuating the triggers of vasoconstriction and platelet aggregation. These studies demonstrated statistically significant improvements of flow mediated dilatation or prevention of vasoconstriction, which will thus improve coronary blood flow and peripheral circulation. One study alluded to an improvement being superior from resistance training (1).
- Quality of Evidence
- Grade A – high quality
- Strength of recommendation
- Grade 1 – strong recommendation
- Physical activity can be recommended to improve the blood flow around the heart and body in most patients with ischaemic heart disease and should be undertaken unless there are compelling reasons to do so.
