Alcohols Effects on the Cardiovascular System PMC

According to Chapter 10 of the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2011), a funnel plot asymmetry test should not be used if all studies are of similar size. For low doses of alcohol, we found that one glass of alcohol had little to no effect on blood pressure and increased heart rate within six hours of drinking. To determine short‐term dose‐related effects of alcohol versus placebo on systolic blood pressure and diastolic blood pressure in healthy and hypertensive adults over 18 years of age. Other research from 2019 found that there was a significant link between moderate alcohol consumption and a risk of hypertension. Some studies suggest low amounts of alcohol may help reduce blood pressure or risk of heart disease. However, the CDC states these findings may be due to other lifestyle differences between people who drink moderately and those who do not.

T​his research was a dose-response meta-analysis of seven different nonexperimental cohort studies. Researchers looked at data from over 19,500 participants, allowing for vast information collection. The studies included participants from the United States, Japan, and South Korea. If you have high blood pressure, also known as hypertension, your health care professional may ask you to cut back on drinking. Alcohol has been reported to diminish baroreceptor sensitivity, which is a key factor in regulating blood pressure (Abdel‐Rahman 1985; Rupp 1996). Baroreceptors or stretch receptors are mechanoreceptors located on the arch of the aorta and the carotid sinus.

Keeping blood pressure within a healthy range can reduce the risk of adverse health outcomes. Many factors can increase someone’s risk for high blood pressure, also known as hypertension. However, researchers are still seeking to understand the full impact of certain risk factors. Hypertension leads to an increased risk of other health problems, including stroke, heart attack, and heart disease.

Summary of findings 1

We recorded the washout period of each included study reported by study authors to decide if there was risk of a carry‐over effect. If it was appropriate to combine cross‐over trials with other trials, we used the recommended generic inverse variance approach of meta‐analysis. We tested the effect of cross‐over trials through sensitivity analysis by excluding them from the meta‐analysis to check if the effect estimate changed significantly.

As a result, we were not able to quantify the magnitude of the effects of alcohol on men and women separately. This is unfortunate, as we have reason to believe that the effects of alcohol on BP might be greater in women. For medium doses of alcohol, moderate‐certainty evidence shows a decrease in SBP and DBP six hours after alcohol consumption, and low‐certainty evidence suggests a decrease in SBP and DBP for 7 to 12 hours after alcohol consumption.

The Centers for Disease Control and Prevention (CDC) notes that if a person has hypertension, they may have a higher risk of conditions such as heart attack, stroke, and heart disease. For example, some people who are on cholesterol-lowering medicines may experience muscle aches 12 step programs for addiction recovery when they drink alcohol. Because alcohol and cholesterol medicine both are processed through your liver, they are, in a sense, competing for clearance. So, it’s important to think about your overall health and talk to a healthcare provider about your personal risk factors.

Those who drink regularly and consume more than the lower risk guidelines are likely to be advised to cut down or stop drinking completely. If you drink regularly, you might feel like alcohol doesn’t affect you as much, but this usually means you’ve developed a tolerance to some of the effects. If you want to cut down, a great way is to have several drink-free days a week.

Any disagreements regarding inclusion or exclusion of studies were resolved by discussion between review authors. The reason for exclusion was documented for each citation at the full‐text level. We also checked the list of references in the included studies and articles that cited the included studies in Google Scholar to identify relevant articles. 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. The blood alcohol concentration (BAC) rises faster in women because they have a smaller volume of distribution (Kwo 1998).

Test out having a break for yourself and see what positive results you notice. The best way of knowing if there’s a problem is to have your blood pressure measured. You can have this done at your GP surgery, some local pharmacies, at your NHS Health Check or you can buy a reliable blood pressure monitor from the pharmacist.

However, current recommendations like those from the Centers for Disease Control and Prevention (CDC) focus on limiting alcohol to one drink a day for women and two drinks a day for men. The CDC also states that to reduce alcohol-related health risks, adults of legal drinking age should limit their alcohol consumption to two drinks or less a day for men and one drink or less for women. If you have high blood pressure, it’s important to discuss any risk factors with your healthcare provider, including alcohol consumption. This article explains the connection between alcohol and hypertension, explores the effects of different types of alcohol, and discusses safe alcohol consumption. It is recommended that there should be at least 10 studies reporting each of the subgroups in question (Deeks 2011).

  1. The aim of Fazio 2004 was to determine the effects of alcohol on blood flow volume and velocity.
  2. But it’s important to make sure those nights of overindulgence are the exception and not the rule.
  3. The bottom line, Klatsky says, is you can’t make a drinking rule that applies broadly for people with high blood pressure.
  4. This systematic review searched only the MEDLINE database for relevant studies, hence it was not exhaustive.

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. Since the kidneys excrete a tenth of ingested alcohol, toxicity in these organs is expected, which could enhance inflammation and renal damage in hypertensive patients. “Alcohol consumption might affect left ventricular diastolic properties, even in nonalcoholic patients,” say the researchers. The bottom line, Klatsky says, is you can’t make a drinking rule that applies broadly for people with high blood pressure. Funnel plots will be used if there is minimum of 10 studies that contribute to a meta‐analysis in order to detect the risk of reporting bias based on the symmetry of the plot (Higgins 2011).

Rossinen 1997 and Van De Borne 1997 reported withdrawal of vagal tone and reduced heart rate variability within an hour after alcohol consumption; this explains the increased heart rate. Buckman 2015, Van De Borne 1997, and Fazio 2001 also reported reduced baroreflex sensitivity following alcohol consumption. Impairment of baroreflex sensitivity results in failure to sense the increase in heart rate and maintenance of cardiovascular homeostasis. Kawano 2000 reported a reduction in plasma potassium levels after alcohol consumption, which might provide another reason for the increase in heart rate.

Heart rate was increased following alcohol consumption regardless of the dose of alcohol. Alcohol has been shown to slow down parasympathetic nervous activity and to stimulate sympathetic nervous activity. Hering 2011, Carter 2011, and Spaak 2008 reported the no-drug approach to erectile dysfunction an increase in muscle sympathetic nervous activity (MSNA), which persists for at least 10 hours after consumption. The vagus nerve is a component of the parasympathetic nervous system and is largely responsible for regulation of the heart rate at rest.

We classified the remaining 33 studies as having low risk of bias because heart rate was measured and reported. 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 (≥ 60 g or ≥ 1 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). We used Cochrane review manager software for all data analyses (Review Manager (RevMan)).

This is when overeating and overindulging in alcohol lead to an irregular heartbeat. Notably, studies have shown that alcohol dehydrogenase variants occur in different individuals and that categorization according to variant nullifies the protective effect of moderate alcohol intake.
