Official title
Comparison of the Effect of Red Wine With Alcohol on Flow-mediated Dilation Versus Red Wine Without Alcohol - a Randomized Clinical Trial
Overview
Introduction: Cardiovascular diseases (CVDs) are the leading cause of global mortality, despite being preventable. Moderate wine consumption has been associated with one of the preventative approaches due to its benefits on cardiovascular health, including endothelial protection and antioxidant effects, attributed to its chemical composition, such as flavonoids. Objective: To assess endothelial function through flow-mediated dilation after the consumption of red wine compared to non-alcoholic wine. Methodology: A parallel, randomized, placebo-controlled clinical trial with a blinded evaluator will be conducted with 20 healthy participants, evaluated at two distinct time points. Participants will be selected to receive either red wine or non-alcoholic wine and will be crossed over after 7 days to receive the opposite beverage from the initial one. The primary outcome will be the change in flow-mediated dilation of the brachial artery pre- and post-intervention in both groups. The secondary outcomes will include the flow-mediated dilation values, brachial artery diameter after the intervention, and measurements of systolic blood pressure (SBP) and diastolic blood pressure (DBP).
Interventions
- Other red wine with alcohol
200 ml of red wine - Demi sec Bordeaux wine 'La Dorni' (alcohol content at 20ºC of 10.1% - Alves \& Martins Bebidas Especiais LTDA - Bandeirantes, Parana - Brazil) - Other red wine without alcohol
200 ml of red wine without alcohol - Demi sec Bordeaux wine 'Casa Navaronne' (alcohol content at 20ºC of 0.23% - Alves \& Martins Bebidas Especiais LTDA - Bandeirantes, Parana - Brazil)
Primary outcome measures
- Flow-mediated dilation [Time frame: 40 minutes after the substance intake]
Secondary outcome measures (4)
- Heart rate [Time frame: 40 minutes after the substance intake]
- Blood pressure [Time frame: 40 minutes after the substance intake]
- Brachial artery diameter at rest [Time frame: 40 minutes after the substance intake]
- Brachial artery diameter after endothelial stress [Time frame: 40 minutes after the substance intake]
