Unfortunately, we found no studies measuring HR more than six hours after the dose. We reviewed available evidence about the short‐term effects of different doses of alcoholic drinks compared to non‐alcoholic drinks on blood pressure and heart rate in adults (≥ 18 years) with both normal and raised blood pressure. There is a very clear link between regularly drinking too much alcohol and having high blood pressure.
- It is important to note that information regarding the method of allocation concealment used in Foppa 2002 and Rosito 1999 was provided by the study author via email.
- Alcoholic drinks, such as beer, spirits and wine, contain the depressant drug ethyl alcohol (ethanol).
- Interestingly, the strength of this association was not consistent across different geographic regions.
Assessment of risk of bias in included studies
Therefore, it is difficult to determine a priori selection of primary and secondary outcome measures for the included studies. Even though these studies reported that participants were randomised to receive alcohol or placebo, the method of randomisation was not mentioned. Although three studies did not report the method of randomisation (Barden 2013; Buckman 2015; Dai 2002), their reported baseline characteristics were well matched. The remaining seven studies reported the method of randomisation used, hence we classified them as having low risk of bias. It is important to note that information regarding to the method of randomisation used in Foppa 2002 and Rosito 1999 was provided by the study author via email. The carry‐over effect in a cross‐over trial can confound the effects of subsequent treatment.
What is the definition of a standard drink?
RCTs with measurements more than 24 hours after alcohol consumption are needed to see how long the effect of high‐dose acute alcohol consumption lasts. High triglyceride levels in the blood stream have been linked to atherosclerosis and, by extension, increased risk of CHD and stroke. We classified seven studies as having high risk of bias (Agewall 2000; Bau 2011; Dumont 2010; Fazio 2004; Karatzi 2013; Maufrais 2017; Van De Borne 1997). Agewall 2000 measured blood pressure upon arrival of participants and did not measure blood pressure after the intervention. The aim of Bau 2011 was to determine the effects of alcohol on heart rate variability, so SBP was not measured in this study.
Other factors to keep in mind
- About 1 in 3 U.S. adults with high blood pressure aren’t even aware they have it and are not being treated to control their blood pressure.
- Several reports suggest that ethanol-induced decreases in myocardial protein synthesis may be mediated in part by decreased activity of an enzyme called mammalian (or mechanistic) target of rapamycin (mTOR) (Lang and Korzick 2014; Vary and Deiter 2005; Vary et al. 2008).
- 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.
- And sure, we’ve all had a night here or there where we’ve had one too many and we know it.
- We also did not rate the certainty of evidence based on the funding sources of studies or on lack of a registered protocol because we did not think this would affect the effect estimates for these outcomes.
After 13 hours, high doses of alcohol increased SBP by 3.7 mmHg compared to placebo. DBP was not significantly affected up to 12 hours after drinking a Oxford House high dose of alcohol, but there was a statistically significant increase in DBP during the ≥ 13 hour time interval after alcohol consumption. This review summarises the acute effects of different doses of alcohol on blood pressure and heart rate in adults (≥ 18 years of age) during three different time intervals after ingestion of alcohol. We are moderately certain that medium‐dose alcohol decreased blood pressure and increased heart rate within six hours of consumption.
Several studies and meta-analyses have been conducted to determine the relationship between alcohol consumption and the risk of developing heart failure in healthy subjects, as well as in those with a history of MI or CHD. Studies also have examined the “safety” of alcoholic beverage consumption in subjects with heart failure. Evidence of oxidative stress is found after short periods of alcohol consumption (2 to 18 weeks), at least in animal models.

Results suggest that the decrease in BP with very high doses of alcohol is greater compared to lower high doses of alcohol. However, the result was heterogeneous; therefore, we are unable to make any implications from this. https://ecosoberhouse.com/ The evidence synthesised in this review was collected from 32 RCTs in 767 participants.
Alcohol prevents the body’s baroreceptors from detecting a need to stretch the blood vessels and increase their diameter, causing an increase in blood pressure. It also regulates metabolism, immune function, and inflammatory pathways. Hypertension, or high blood pressure, is a very common condition worldwide.
Having more fluids in the body directly increases blood pressure levels. In hospital, your medications are adjusted to control your blood how does alcohol affect blood pressure and heart rate? pressure, but you aren’t drinking alcohol at that time. Back home, if you start drinking regularly again and your blood pressure changes, your GP can alter your medications.
