Ways Alcohol Affects Your Heart

Most studies gave participants 15 to 30 minutes to finish their drinks, started measuring outcomes sometime after that, and continued taking measurements for a certain period, but there were some exceptions. Chen 1986 did not report consumption duration nor timing of measurement of BP and HR. Dai 2002 gave participants five minutes to consume high doses of alcohol and measured outcomes immediately. On the other hand, Fantin 2016 allowed participants to continue drinking during the period of outcome measurement. These differences in alcohol consumption duration and in outcome measurement times probably contributed to the wide variation in blood pressure in these studies and affected overall results of the meta‐analysis.

Senior Cardiac Nurse Christopher Allen finds out more from Professor Sir Ian Gilmore, Consultant Physician and Gastroenterologist at Royal Liverpool University Hospitals. Various drinks may help a person reduce their blood pressure, such as tea or beetroot juice. A person who has hypertension should avoid consuming too much caffeine or soda. A person can speak with a qualified healthcare professional if they find it difficult to reduce their alcohol intake.

We did not consider the lack of blinding of participants as a downgrading factor for certainty of evidence because we do not think that it affected the outcomes of this systematic review. Changes in blood pressure and heart rate after alcohol consumption were not the primary outcomes of interest in most of the included studies. We do not think participants were anticipating any significant influence on blood pressure or heart rate after drinking. Several RCTs have reported the magnitude of effect of alcohol on blood pressure, but because those trials are small, their findings are not sufficient to justify a strong conclusion. In 2005, McFadden and colleagues conducted a systematic review of RCTs, which investigated the haemodynamic effects of daily consumption of alcohol (McFadden 2005).

  • Some beverages may contribute to high blood pressure, and avoiding them may help people manage hypertension.
  • A healthcare professional can help a person find treatment and support to help them stop drinking or lower their intake.
  • Alcohol has been a part of almost every human culture for a very long time (McGovern 2009).
  • However, in a recently conducted Mendelian randomization study, Vu and colleagues (2016) reported that low-to-moderate alcohol consumption reduced triglyceride and LDL-c and increased HDL-c, in particular the HDL2-c subfraction.
  • For healthy adults, that means up to one drink a day for women and up to two drinks a day for men.
  • Dumont 2010 measured blood pressure during the RCT, but study authors did not provide the before and after measurement of DBP.

People who drink regularly consume a mean of 33 g of anhydrous alcohol per day, with beer being the most common alcoholic beverage. “Alcohol is certainly not the sole driver of increases in blood pressure; however, our findings confirm it contributes in a meaningful way. Limiting alcohol intake is advised, and avoiding it is even better,” Vinceti said. Sara Tasnim (ST) and Chantel Tang (CT) drafted the protocol with help from JMW. Both ST and CT independently assessed studies for inclusion or exclusion and assessed the risk of bias of all included studies. We identified Stott 1987 and Barden 2013 from Analysis 3.1 and Analysis 3.2 as having a considerably lower standard error (SE) of the mean difference (MD) compared to the other included studies.

Acute administration of alcohol stimulates the release of histamine and endorphin, which interferes with baroreflex sensitivity (Carretta 1988). Your healthcare provider may recommend a blood pressure medication as well. does alcohol affect bp If you continue to drink, alcohol may reduce the effectiveness of these medications or even cause a serious medical interaction. Studies have shown a link between alcohol and hypertension, or high blood pressure.

Blood Pressure: Even Moderate Drinking Can Raise Your Risk.

Drinking very large amounts all at once can slow your heart rate and breathing down to a dangerously low level. A study from 2023 found that tea consumption could help reduce a person’s risk of hypertension by 10%. Researchers noted this effect varied depending on the type of tea a person drank. Additionally, the American Heart Association states that the idea that red wine is good for the heart may be untrue. The organization suggests the results of studies that report the heart benefits of red wine may instead have a basis in lifestyle factors other than alcohol. Read on to learn more about alcohol and blood pressure, as well as what drinks may benefit a person who has hypertension and when to talk with a doctor.

“It has calories, and calories can cause weight gain and obesity, which will lead to high blood pressure,” Dr. Mintz says. They do not pass readily through cell membranes, and they are major components of very-low-density lipoproteins (VLDLs), which are converted in the blood to LDLs. High levels of triglycerides in the blood have therefore been linked to atherosclerosis, heart disease, and stroke. Researchers have found evidence of mitochondrial dysfunction or impaired bioenergetics related to alcohol consumption. This is not surprising, because mitochondria are a major target for free-radical injury.

The aim of Bau 2011 was to determine the effects of alcohol on heart rate variability, so study authors did not measure and report DBP. For Buckman 2015, blood pressure was recorded beat to beat continuously, but DBP was not reported. Dumont 2010 measured blood pressure during the RCT, but study authors did not provide the before and after measurement of DBP.
