Quality Of The Evidence
We graded the overall certainty of evidence using the GRADE approach via GRADEpro GDT software we formulated summary of findings tables.
We created three SoF tables to show the certainty of evidence and the summary of effects on outcomes of interest for high , medium , and low doses of alcohol.
Ratings of the certainty of evidence ranged from moderate to low in this review, which suggests that the effect estimates of alcohol might be slightly different than the true effects. For high doses of alcohol, we found moderatecertainty evidence showing a decrease in SBP and lowcertainty evidence suggesting a decrease in DBP within the first six hours and 7 to 12 hours after consumption. Moderatecertainty evidence shows that SBP and DBP rise between 13 and 24 hours after alcohol ingestion.
For medium doses of alcohol, moderatecertainty evidence shows a decrease in SBP and DBP six hours after alcohol consumption, and lowcertainty evidence suggests a decrease in SBP and DBP for 7 to 12 hours after alcohol consumption. After 13 hours of consumption, SBP and DBP were raised the certainty of evidence was low and medium, respectively.
For low doses of alcohol, we found lowcertainty evidence suggesting that SBP, DBP, and MAP fall within the first six hours after alcohol consumption.
Myth: Red Wine Is Good For Everyone
Fact: Women and men experience alcohol differently, so they should consume it differently. One glass of wine per day is plenty for women, while men shouldnt drink more than two glasses a day.
We still dont really know if red wine is good for heart health. Until theres more information available, its best to drink moderately and talk to your doctor. For information about other heart-healthy practices, contact the UPMC Heart and Vascular Institute.

How The Intervention Might Work
The molecular mechanisms through which alcohol raises blood pressure are unclear. Alcohol can affect blood pressure through a variety of possible mechanisms. Previous research suggests that acute alcohol consumption affects the reninangiotensinaldosterone system by increasing plasma renin activity . The RAAS is responsible for maintaining the balance of fluid and electrolytes. An increase in plasma renin results in increased production of angiotensin I , which is converted to angiotensin II by angiotensinconverting enzyme . The hormone AII is a potent vasoconstrictor that stimulates aldosterone and vasopressin secretion from the adrenal gland, promoting sodium and water retention . As a result, peripheral resistance and blood volume are increased, leading to elevated arterial blood.
Several clinical trials in humans and studies conducted in animal models have reported stimulation of the sympathetic nervous system and increased noradrenaline after consumption of alcohol . When noradrenaline stimulates the adrenergic receptors located in the heart muscles, heart rate and blood pressure are increased.
Another possible mechanism is the increase in plasma cortisol levels following heavy alcohol consumption . Several studies have suggested a role for cortisol in alcoholinduced hypertension . Cortisol is a type of steroid hormone, and the presence of excess cortisol has been associated with elevated blood pressure in normotensive individuals .

This suggests that red wine is a great way to treat one of Western worlds biggest killers hypertension, or high blood pressure. Find out 8 things to eat to naturally lower blood pressure.
In this study, 40 male rats were fed either a high fructose diet or a high fructose diet that was supplemented with different doses of red grape berry cells. The amounts were 200, 400, and 800mg/kg of body weight per day, over a 5 week period. The rats blood pressure, plasma triglycerides, adiponectin, and insulin levels were measured at the beginning of the trial then again after 3 weeks and then again after 5 weeks. The red grape cells effects on vasodilation were also monitored.

What Causes High Blood Pressure And Who Is At Risk
Those at risk are persons above the age of fifty-five, who have a forty percent chance of getting it and these chances heighten to ninety percent . There are also high chances of getting it during pregnancy. This, however, can reverse itself after giving birth.
High salt intake, high-stress levels, smoking, alcohol consumption, and physical inactivity are some of the leading risk factors for high blood pressure.
Blood pressure is measured in a ratio and written as two numbers where the top number indicates systolic blood pressure, and the lower one indicates diastolic blood pressure. The systolic pressure can be defined in a laymans language as the rate at which the heart pumps and supplies blood to other parts of the body. On the other hand, the diastolic pressure is the rate at which the heart is at its normal relaxed mode, receiving blood from different body parts.
The prescription of high blood pressure medications, a proper diet and exercises can curb or in other cases reverse the problem. Heart failure can occur if high blood pressure is uncontrolled.

Expert Reaction To Study On A Molecule In Red Wine And Blood Pressure
Research published in Circulation demonstrates that a molecule found in red wine causes a drop in blood pressure.
Prof Roger Corder, Emeritus Professor of Experimental Therapeutics, Queen Mary University of London, said:
I have been pushing back for many years against associating resveratrol with any effects of red wine. In fact, most red wines have undetectable levels of resveratrol. I published correspondence in Nature in 2003 highlighting the divide between doses of resveratrol being used experimentally compared to the amounts present in red wine. But the urban myth that resveratrol might explain the health benefits of regular red wine consumption has persisted. The dose here of 320 mg/kg in mice can be considered equal to treating a human with 15 to 20 g resveratrol. This amount is ridiculous and in red wine terms equivalent to more than 3000 litres of wine.
Dr Bob Patton, Alcohol Researcher & Lecturer in Clinical Psychology, University of Surrey, said:
Excessive alcohol consumption is associated with increases in blood pressure, and this can lead to cardiovascular problems like heart attacks and strokes, so its a good idea to reduce it. Relaxing with a glass of red is one way to unwind at the end of the day, but on its own that is not going to help tackle hypertension losing weight, taking regular exercise and lowering your stress levels are three of the best ways to do this.
Dr Bob Patton: No conflicts of interest.
Does Excessive Drinking Contribute To Heart Disease
Heavy drinking, on the other hand, is linked to a number of poor health outcomes, including heart conditions. Excessive alcohol intake can lead to high blood pressure, heart failure or stroke. Excessive drinking can also contribute to cardiomyopathy, a disorder that affects the heart muscle.
Whats more, alcohol can contribute to obesity and the long list of health problems that can go along with it, McEvoy says: Alcohol is a source of excess calories and a cause of weight gain that can be harmful in the long term.
The takeaway, McEvoy says, is what you probably already knew: If you choose to drink alcohol, stick to moderate levels of drinking, and dont overdo it. Were not talking about going out and drinking yourself merry and then expecting good heart outcomes, McEvoy says.

Drinking Wine Or Beer Has Same Result: Higher Blood Pressure
- American Heart Association
- Whether the drink of choice is a frosty beer or a full-bodied red wine, the effect is the same higher blood pressure, according to research reported in Hypertension: Journal of the American Heart Association.
DALLAS, April 19 Whether the drink of choice is a frosty beer or a full-bodied red wine, the effect is the same higher blood pressure, according to research reported in Hypertension: Journal of the American Heart Association.
A positive relationship between alcohol consumption and blood pressure is well established, but the relative effect of specific alcoholic beverages is controversial, said lead researcher Renate R. Zilkens, Ph.D., research fellow in the School of Medicine and Pharmacology at University of Western Australia.
Red wine appears to have a dual effect on blood vessels. The alcohol in it may raise blood pressure, but the polyphenolic compounds in red wine may have antioxidant effects and help relax blood vessels. There may be subtle differences between wine, beer and spirits on heart rate and other cardiovascular measurements.
Researchers investigated whether red wine has less of an impact on blood pressure than other alcoholic beverages and whether it improved vascular function. They studied 24 healthy, non-smoking men aged 20 to 65. All the men were daily drinkers, with normal blood pressure and no history of heart disease.
Removing alcohol from red wine did not lower blood pressure either, Zilkens said.
Many Factors Drive Blood Pressure
But he pointed out that this is an observational study, so it cant show for certain the health benefits or harms of moderate drinking.
For that, youd need a randomized controlled trial, in which groups of people are assigned to drink a certain amount of alcohol each day for months or years.
For example, people who drink lightly or abstain may also tend to eat healthy, exercise regularly, and get enough sleep all of which can lower their blood pressure.
Grayver said the type of alcohol that people drink could also make a difference. Red wine, for instance, is thought to have anti-inflammatory effects on the body, which may also impact heart health.
And what you eat with your glass of beer or wine or shot of whiskey can affect your blood pressure, too.
All of the pretzels, peanuts, and other snacks that go along with alcohol consumption have a significant amount of salt in them, said Grayver. That in itself could be driving the hypertension.
Even news stories that talk about the heart benefits of alcohol may play a part.
It is possible that once someone receives a diagnosis of hypertension, they may then be incentivized to drink alcohol in moderate amounts, said Marcus.
In a 2015 study, Marcus and his colleagues found that people who believed that alcohol is heart healthy were more likely to drink more, compared to those who thought otherwise.

Alcohol Consumption For Someone With High Blood Pressure
If someone has high blood pressure, they should avoid drinking alcohol as much as possible. Most doctors recommend that people with high blood pressure should exercise and eat a healthy diet. Part of this healthy diet is avoiding alcohol use.
While alcohol does contribute to high blood pressure, it may be safe to use small amounts of alcohol. The American Heart Association says the maximum daily amount of alcohol consumption for people with hypertension is two drinks for men and one drink for women. Ultimately, the less you drink, the better it will be for your hypertension. The AHA recommendations may not work best for everyone, however, so be sure to speak with a doctor about your specific situation.
How Much Alcohol Is Safe For Hypertension Patients
Alcohol has been well studied in relation to high blood pressure, and while some clinical studies suggest that moderate consumption can be used to lower blood pressure, most experts recommend refraining from any alcohol use to maintain good overall health.
In addition to an increased risk for cardiovascular issues, consuming more than three alcoholic drinks daily can increase the risk for high blood pressure by 70%.
Cutting down on alcohol can be challenging for heavy drinkers, whereas those who drink socially may be able to avoid alcohol more easily.
Hypertension patients who need to limit their alcohol should do so at a slow and steady pace. Reduce drinks over several weeks as blood pressure could rise significantly if heavy drinkers stop use abruptly.
High blood pressure patients who do consume alcohol are advised to limit drinks in accordance to age and existing health condition.
Moderation is key and can be defined as two alcoholic drinks daily for males under 65 years of age and one daily glass for older men. Women are advised to limit alcohol beverages to one per day at any age.
One drink may be a 12-oz. glass of beer, a 5-oz. glass of wine, or a 1.5-oz. glass of spirits.

What Are The Precautions Of Red Wine For Lowering High Blood Pressure
So, drinking the best red wine for health can help you fight high blood pressure. Good! Youre probably planning on getting several bottles of it so that you will be able to have a drink every night. But before you do splurge on this beverage in the hopes that it will help you regulate your blood pressure, there are a few precautions that you need to consider.
For one thing, too much consumption of even the best red wine for health can have its drawbacks such as weight gain. This depends mostly on the calorie content of the drink. If you drink more than a glass or two, there is a high chance that you are contributing to your weight gain.
Another precaution to take into consideration when it comes to drinking red wine is that it may cause blood thinning especially in those who are taking blood thinners as part of their medication. Combining the two can be a health hazard. There is also a possibility of side effects when taking medications and drinking red wine which you need to be aware of if you are trying to keep your blood pressure to a minimum. If you are not sure about the side effects of wine and medications, you should ask your doctor for a consult.
Affect Adverse Reaction Severity Factors
The severity of the adverse reactions caused by the interaction between wine and blood pressure medications is affected by factors such as your gender and age, the National Institute on Alcohol Abuse says. Other factors that affect severity are the ingredients of the medication and the time you took the medication. Women are more susceptible to the effects of alcohol because their bodies have less water than men.
Your body’s ability to break down alcohol becomes impaired as you age. This means your risk of adverse alcohol interactions grows progressively higher as you age. Different types of medications peak at different rates. So even if you took the medications hours prior to drinking wine the possibility of experiencing adverse reactions remains.

What Is High Blood Pressure
A normal heart pumps blood around the body easily, at a low pressure. Having high blood pressure means that your heart must pump harder, and the arteries have to carry blood thats flowing under greater pressure. This puts a strain on your arteries and your heart, which in turn increases your risk of a heart attack, a stroke or of suffering from kidney disease.
