Insights
High uric acid is linked to heart disease. Inhibiting xanthine oxidase with drugs like Allopurinol may improve cardiac function and benefit heart failure patients.
Area of Science:
- Cardiology
- Biochemistry
Background:
- Uric acid's role in cardiac function is increasingly recognized.
- Gout and elevated uric acid levels have been associated with coronary heart disease for decades.
Purpose of the Study:
- To explore the physiological effects of xanthine oxidase inhibition.
- To evaluate the potential benefits of xanthine oxidase inhibition for patients with congestive heart failure.
Main Methods:
- Review of several hundred studies on xanthine oxidase inhibition physiology.
- Hypothesizing benefits based on known physiological effects.
Main Results:
- Xanthine oxidase inhibition improves cardiac output, endothelial function, and reduces myocardial infarct size.
- It also decreases inflammation, myocardial oxidative stress, and platelet adhesiveness.
Conclusions:
- The physiological effects of xanthine oxidase inhibition suggest significant benefits for congestive heart failure patients.
- A large-scale placebo-controlled trial with Allopurinol is anticipated to confirm these benefits.
Abstract:
The recognition that uric acid plays a significant role in cardiac function has been slow to be appreciated. About 50 years ago it was recognized that gout and high uric acid levels were often a marker for coronary heart disease, Since then the literature has contained several hundred studies which have demonstrated a great deal of the physiology of xanthine oxidase inhibition. A reduction in xanthine oxidase improves cardiac output, improves endothelial function, reduces myocardial infarct size, reduces inflammation, reduces myocardial oxidative stress and platelet adhesiveness. It seems logical that these effects would be beneficial to patients with congestive heart failure. A large placebo controlled trial with Allopurinol seems very likely to demonstrate that this old fashioned drug provides a new found benefit.
