This review did not find any eligible RCTs that reported the effects of alcohol on women separately. Because women could be affected differently by alcohol than men, future RCTs in women are needed. If future RCTs include both men and women, it is important that their blood pressure and heart rate readings are reported separately. Although eligible studies included East Asian, Latino, and Caucasian populations, they lacked African, South Asian, and Native Hawaiian/other Pacific Islander representation. Most of the hypertensive participants in the included studies were Japanese, so it is unclear if the difference in blood pressure between alcohol and placebo groups was due to the presence of genetic variants or the presence of hypertension.
The study author explained the blinding method in detail in an email, so we classified this study as having low risk of bias. Different types of alcoholic beverages including red wine, white wine, beer, and vodka were used among 32 studies. The dose of alcohol ranged between 0.35 mg/kg and 1.3 g/kg, and alcohol was consumed over five minutes and over one hour and 30 minutes. It is important to note that the dose of alcohol was comparatively higher (≥ ۶۰ g or ≥ ۱ g/kg) in nine studies (Bau 2005; Buckman 2015; Hering 2011; Narkiewicz 2000; Rosito 1999; Rossinen 1997; Stott 1987; Van De Borne 1997; Zeichner 1985). Alcohol can affect drinkers differently based on their age, sex, ethnicity, family history, and liver condition (Cederbaum 2012; Chen 1999; Gentry 2000; Thomasson 1995). Previous studies reported that women are affected more than men after drinking the same amount of alcohol because of their lower body weight and higher body fat.
- In most cases, low blood pressure can be managed effectively with safe, simple lifestyle modifications.
- The acute effects of alcohol on the myocardium include a weakening of the heart’s ability to contract (negative inotropic effect).
- It is important for future studies to report on clinically relevant outcomes, including serious adverse events and quality of life.
- They may repeatedly check your blood pressure and pulse rate — after you’ve been lying down for a few minutes, right after you stand up, and within a few minutes after you stand quietly.
- A recent study shows the least mortality at 100 g/week or less of alcohol, with a dose-dependent relationship between alcohol and stroke, IHD, fatal hypertensive disease, heart failure, and fatal aortic aneurysm.
Adequate randomised controlled trials are needed to provide additional evidence on this specific question. Despite the progress in standardizing measurement of alcohol, studies still vary in how they define the different levels of drinking, such as low-risk or moderate and heavy drinking. Most often, low-risk or moderate drinking has been defined as 1 to 2 standard drinks per day and heavy alcohol consumption as 4 or more standard drinks per day.
Senault 2000 published data only
High alcohol consumption also increased heart rate from 7 to 12 hours and after 13 hours. Most of the evidence from this review is relevant to healthy males, as these trials included small numbers of women (126 females compared to 638 males). The associations between drinking and CV diseases such as hypertension, coronary heart disease, stroke, peripheral arterial disease, and cardiomyopathy have been studied extensively and are outlined in this review. Although many behavioral, genetic, and biologic variants influence the interconnection between alcohol use and CV disease, dose and pattern of alcohol consumption seem to modulate this most.

The included study did not provide data for analysis of serious adverse events and quality of life of participants. Altered platelet responses (e.g., increased platelet activation/aggregation) leads to blood-clot formation (or alcoholism and mental health thrombosis) in certain CV conditions. Anticlotting therapies are therefore the cornerstone of managing acute coronary syndromes. Not surprisingly, alcohol consumption has complex and varying effects on platelet function.
Therefore, as in animal studies, the effects of ethanol on endothelial function in humans likely depend on the dose and duration of ethanol consumption. According to the published protocol, we intended to include only double‐blind RCTs in this review. Because higher doses of alcohol exert specific pharmacological effects on drinkers, we had a few double‐blind RCTs after the first screening. Considering the difficulty of masking in these types of studies, we decided to also include single‐blind and open‐label studies in the review. We took several steps to minimise the risk of selection bias to identify eligible studies for inclusion in the review. We also checked the lists of references in the included studies and articles that cited the included studies in Google Scholar to identify relevant articles.
We calculated and reported mean difference (MD), with corresponding 95% confidence interval (95% CI). One recent study in the Journal of the American College of Cardiology found that in 17,059 participants, those who drank moderately and those who drank heavily were both at significantly higher risk of high blood pressure than those who never drank. Alcohol consumption increases the amount of calcium that binds to the blood vessels. This increases the sensitivity of the blood vessels to compounds that constrict them. 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.
Neurohormonal disruptions may mediate the mechanisms of harm in alcohol consumption. For example, sympathetic activation could underlie the observed BP elevation, as could the disruption of carotid baroreceptor responses that regulate BP. This disruption might be due to higher amounts of endorphins and histamine released by alcohol. You might have other tests, such as an ECG (electrocardiogram) to measure heart rate and rhythm and an echocardiogram (an ultrasound test to visualize the heart). You may also have blood tests to look for anemia or problems with your blood sugar levels.
Quality of the evidence
People who drink regularly consume a mean of 33 g of anhydrous alcohol per day, with beer being the most common alcoholic beverage. Ethanol-induced changes may be related to oxidative or nonoxidative pathways of ethanol metabolism. More than one mechanism may be is there a difference between a sober house and a halfway house activated and may lead to the multitude of ethanol-induced changes in cellular proteins and cell function. As reviewed in the text, data from pharmacologic and transgenic approaches revealed an important role for oxidative stress and the hormone angiotensin II.
On the other hand, some guidelines on hypertension management make specific recommendations on limits to alcohol consumption (Hypertension Canada 2018). Therefore, it is considered of great interest to assess the effects of interventions to reduce alcohol intake in terms of blood pressure changes in hypertensive people. The magnitude and direction of the effects of alcohol on blood pressure depend on the time after alcohol consumption.

The Information Specialist modelled subject strategies for databases on the search strategy designed for MEDLINE. In this interview, Rami Mehio, head of software and informatics at Illumina, shares his experiences and contributions to major genomic projects like the UK Biobank’s whole genome sequencing. He discusses the challenges and innovations in genomic data analysis, highlighting Illumina’s role in advancing genetic research and precision medicine.
Overall completeness and applicability of evidence
Above 14 drinks a week, heart failure risk is higher, with hypertensive patients who drink more being more likely to show subclinical features of heart damage affecting the heart’s diastolic function. This is a dose-dependent association, as is that with left ventricular hypertrophy. Nevertheless, there is much evidence that the moderate consumption of alcohol is beneficial for cardiovascular health, beginning from the “French Paradox” – the finding of reduced ischemic heart disease (IHD) among those who regularly drink red wine. 3Greenfield and colleagues (2005) studied the effects of alcohol at meal time in a group of nonsmoking, healthy postmenopausal women. Each woman was given either no alcohol or 15 g of alcohol (1 standard drink) with either a low-carbohydrate or a high-carbohydrate, high-fat meal. The women’s metabolic measurements were then taken over the next 6 hours.
Because there are no published standards for differentiating between low and medium doses of alcohol, we chose the alcohol content in one standard drink as the threshold between low dose and medium dose. Because the alcohol content in one standard drink varies among different countries (ranging from 8 g to 14 g), we chose the Canadian standard for an alcoholic beverage, which is 14 g of pure alcohol (CCSA). Accordingly, we considered up to 14 g of alcohol as a low dose of alcohol. To differentiate between medium and high doses, the Canadian Centre on Substance Use and Addiction (CCSA) identifies less than 30 g of alcohol for men and less than 20 g of alcohol for women as the threshold for low risk of alcohol intake (CCSA).
It also may ease any depression and anxiety and elevate your self-esteem. In fact, over the long term, Blacks appear more prone to BP elevations than Whites or are alcoholism and drug addiction disabilities Asians. In one study, the risk for high BP among men increased by a fifth with 1-2 drinks but by half and three-fourths with 3-4 and 5 or more drinks a day.
It can also happen (with no symptoms) to people who are very physically active, which is more common in younger people. ST extracted data, checked data entry, conducted data analysis, interpreted study results, and drafted the final review. We graded the overall certainty of evidence using the GRADE approach via GRADEpro GDT software (GRADEpro 2014); we formulated summary of findings (SoF) tables. Many interrelated changes are possibly responsible for the biphasic effect of alcohol on blood pressure. A dose of 14 grams of pure alcohol/ethanol or less was defined as a low dose of alcohol.
