Trial Summary

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, since the trial includes patients with type 2 diabetes controlled by oral agents or insulin, it seems likely that you can continue those medications.

What data supports the effectiveness of the drug resveratrol for coronary artery disease?

Research suggests that resveratrol, a compound found in grapes and red wine, may protect the heart by improving blood flow and reducing heart damage in animal models. It has shown potential benefits in preventing heart problems and improving heart health in humans, although more research is needed to confirm its effectiveness for coronary artery disease specifically.12345

Is resveratrol safe for human use?

Resveratrol has been found to be safe and reasonably well-tolerated in humans at doses up to 5 grams per day, although mild to moderate side effects may occur, suggesting future trials will use lower doses.24678

How does the drug trans-resveratrol differ from other treatments for coronary artery disease?

Trans-resveratrol is unique because it is a natural compound found in red wine and other plants, known for its antioxidant and anti-inflammatory properties. Unlike traditional treatments, it may improve heart health by protecting against oxidative stress and enhancing blood flow in the heart, potentially offering a novel approach to managing coronary artery disease.246910

What is the purpose of this trial?

Major ProblemPeople with diabetes have an increased risk of heart disease, heart failure, and death from a cardiovascular cause. Diabetes prevents efficient metabolism of fuel, causes inflammation and vascular disease that blocks normal blood flow, and inhibits the function of the heart after injury. These changes make diabetics more susceptible to heart attacks and heart failure.Resveratrol is found in grapes and red wine and has been shown to have beneficial effects in diabetic patients. In previous studies the investigators have shown that resveratrol can improve heart metabolism and function in pigs with diabetes and chronic lack of blood flow to the heart.QuestionsThe investigators believe resveratrol will help reverse the negative effects of diabetes on the heart. The questions are: 1.How does the molecular machinery in the hearts of patients with diabetes differ from patients without diabetes? 2.Will resveratrol have an effect on heart metabolism, intracellular signaling, inflammation and blood vessel function? 3.Will resveratrol improve the number and function of cardiac stem cells, cells involved in heart repair? The investigators have been safely collecting tissue from the hearts of patients undergoing heart surgery. Preliminary studies show the investigators can isolate and study cells. The investigators have collected and assessed the function of endothelial cells, a measure of vascular health and can measure the level of endothelial injury and have studied the make-up of caveolae, structures on the cell membrane that are important for cell signaling and are negatively impacted by diabetes. This study is a unique collaboration among cardiologists, cardiac surgeons, and basic scientists.

Findings from Research

Cis-resveratrol significantly reduces collagen-induced platelet aggregation in vitro, with a decrease of 43.5% at a concentration of 1 x 10(-5) M, indicating its potential as an anti-aggregating agent.
Trans-resveratrol also shows anti-aggregating effects but is slightly less effective than cis-resveratrol, suggesting that both isomers should be considered when evaluating resveratrol's overall activity in biological systems.
