Alcohol consumption has been shown to have complex, and sometimes paradoxical, associations with cardiovascular diseases (CVDs). Several hundred epidemiological studies on this topic have been published in recent decades. Methodological shortcomings, such as exposure classification and measurement, reference groups, and confounding variables (measured or unmeasured) are discussed. Based on systematic reviews and meta-analyses, the evidence seems to indicate non-linear relationships with many CVDs.

In addition, other atherogenesis-related factors (e.g., the influence of hormones) that are not addressed in this article may be influenced by the use of alcohol, and research is needed to investigate these factors as well. The proportion of cardiomyopathy cases attributable to alcohol abuse has ranged from 23 to 40 percent (Piano and Phillips 2014). Recently, Guzzo-Merello and colleagues (2015) reported that, among 282 patients with a dilated cardiomyopathy phenotype, 33 percent had ACM.

How Alcohol Affects Your Heart

Meanwhile, the bottom number is the diastolic pressure, which is the amount of pressure in the blood vessels when the heart relaxes. What’s more, alcohol can contribute to obesity and the long list of health problems that can go along with it. Alcohol is a source of excess calories and a cause of weight gain that can be harmful in the long term. Exercise can also boost HDL cholesterol levels, and antioxidants can be found in other foods, such as celebrities with fetal alcohol syndrome fruits, vegetables and grape juice.

While moderate amounts of alcohol can offer some heart benefits, too much can have damaging effects.

Shape of the relation between alcohol consumption and CVD categories based on current evidence syntheses. Normally, a balance exists between the compounds involved in blood clot formation and dissolution (i.e., fibrinolysis). The principal physiologic inhibitor, plasminogen activator inhibitor type-1 (PAI-1), terminates the fibrinolytic process.

Characteristics of studies evaluating anti-inflammatory, antioxidant, and antithrombotic effects of alcohol. An alcoholic beverage has different definitions depending on the country and guideline celebrities that drink alcohol everyday revised. For example, in the United Kingdom an alcoholic beverage contains 8 g of ethanol, whereas in the United States and several European countries (i.e., Austria, France, Netherlands, Spain, among others) this value ascends to 10 g of ethanol [2,3]. The latter is the most frequently used measure, as stated by the World Health Organization (WHO) [3,4]. Among these is the activation of mitogen-activated protein kinases (MAPK) signaling cascades.

Platelet function is a key factor in the initiation and progression of blood clot formation (i.e., thrombosis). Platelets adhere to the roughened surface, and a cascade of events culminates in the formation of the enzyme thrombin. Thrombin interacts with platelet membrane receptors, resulting in stimulation of the enzyme phospholipase C. This enzyme mediates platelet aggregation through the formation of two compounds, inositol triphosphate and diacylglycerol. The former compound mobilizes ionized calcium from intracellular stores, and the latter activates another enzyme known as protein kinase C.

Most investigators also define the amount of alcohol that constitutes a “standard” drink as 12 to 15 g (with only slight variation). That fourth drink at the bar may feel like it’s relaxing you, but it’s actually affecting your body differently than you might think. This is especially true when you engage in binge drinking (that’s defined as four or more drinks within two hours for women and people assigned female at birth, and five or more drinks within two hours for men and people assigned male at birth).

Chylomicrons and very low density lipoproteins (VLDL) are two other major classes of lipoproteins in the body. Chylomicrons, the largest lipoprotein particles, carry triglycerides consumed in food from the intestine to the blood, whereas the smaller VLDL particles are formed mainly in the liver and enter the blood circulation to transport cholesterol and triglycerides to peripheral tissues throughout the body. In the capillaries within fatty tissues and muscles, an enzyme known as lipoprotein lipase (LPL) breaks down triglycerides in both chylomicrons and VLDL to substances used in metabolism and energy storage (i.e., fatty acids and glycerol). Other ethanol-induced changes may be related to enzymes that modulate protein synthesis and/or breakdown (e.g., ubiquitine-ligases). 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). MTOR regulates cell growth, proliferation, motility, and survival; protein synthesis; and transcription (Donohue 2009).

1. The biochemical mechanisms for alcohol-induced increases in HDL levels are largely unknown, however.
2. In a meta-analysis comprising 957,684 participants and 38,627 events, a J-shaped curve in relation to lifetime abstainers was observed in women for both fatal and non-fatal IHD outcomes, and an inverse relationship was observed in men with non-fatal IHD events [16].
3. In the capillaries within fatty tissues and muscles, an enzyme known as lipoprotein lipase (LPL) breaks down triglycerides in both chylomicrons and VLDL to substances used in metabolism and energy storage (i.e., fatty acids and glycerol).
4. However, modulatory influences related to drinking patterns, genetic susceptibility, nutritional factors, ethnicity, and gender also many play a role (Piano and Phillips 2014) (figure 4).

Dr. Cho also warns that if you have liver dysfunction or take other medicines that are processed through the liver, your risks might be different. Talk to your healthcare provider about how alcohol might interact with your prescription medicines. While some people develop a tolerance to alcohol over time, this isn’t true for everyone — and this ability doesn’t last forever, Dr. Cho notes. It’s also important to know that the ways in which alcohol affects your heart will vary from person to person, depending on your age and other conditions you may have. 2The terms “alcoholism” and “alcoholic” as used in this article are summary terms for the diagnoses of alcohol abuse and alcohol dependence.

However, the role of CETP in increasing HDL is questionable, since this effect is inconsistent at low or moderate levels of alcohol consumption (e.g., Nishiwaki et al. 1994). Similarly, the observed increase in the activity of the enzyme LCAT may not play an important role in the alcohol-induced HDL increase (Nishiwaki et al. 1994). In a meta-analysis of 11 cohorts published in 2014, an inverse risk relationship between average alcohol consumption and IHD in patients with hypertension was reported [37]. Similar associations have been reported among people with diabetes and non-fatal myocardial infarction [38,39,40,41,42]. A recent large-scale study from the UK reported a J-curve for most CVD outcomes in patients with CVD [43].

The keywords used for this search were alcohol consumption, hypertension, diabetes mellitus type 2, dyslipidemia, can you mix shrooms and alcohol inflammation, oxidative stress, among others. In 2016, 32.5% of people worldwide were current drinkers, and the mean amount of alcohol consumed was 0.73 standard drinks daily for women and 1.7 for men [9]. The same year, the prevalence of current drinking was 72% and per capita alcohol consumption among adults in Europe (EU) was 11.3 liters of pure alcohol [1]. Nonetheless, consumption in the EU has decreased over the last few years, in contrast to consumption worldwide, which, in fact, is on the rise [1].

For example, dogs fed alcohol for 1 year and rats fed alcohol for 8 months showed significant decreases in left ventricular function (Capasso et al. 1991). Another possible mechanism for CAD risk reduction relates to the inhibition of cell proliferation that results from cellular signaling. Blocking the action of the enzyme known as hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase has been shown to suppress cell proliferation, among other effects (e.g., cholesterol reduction), and thus may provide another way to reduce plaque formation and slow atherosclerosis development.

More recently, Cosmi and colleagues (2015) examined the effects of daily wine consumption in subjects enrolled in an Italian trial of heart failure patients (mean age ~67), most of whom had reduced ejection-fraction heart failure. Different levels of daily wine consumption (i.e., sometimes, 1 to 2 glasses/day, and ≥3 glasses/day) had no effect on fatal or nonfatal outcomes (e.g., hospitalization for a CV event). Subjects who drank wine more often, however, were less likely to have symptoms of depression and more likely to have a better perception of health status. They also had lower levels of circulating inflammatory markers, such as C-terminal proendothelin-1 and pentraxin-3 (Cosmi et al. 2015). Another trend in recent studies of alcohol and CV risk and disease is to include a measurement for binge drinking. In most investigations, this means consuming more than 5 standard drinks on a single occasion for men and more than 4 standard drinks for women.

Future studies would benefit from using direct biomarkers of alcohol consumption, such as phosphatidylethanol (PEth), to corroborate self-report of alcohol consumption and distinguish among low, moderate, and heavy alcohol consumption (Kechagias et al. 2015; Piano et al. 2015). The way in which alcohol consumption has been measured and categorized varies, sometimes making it challenging to compare data among studies. More studies today report alcohol consumption in terms of either “drinks” or grams/units of ethanol per day or week, and alcohol consumption is measured by self-report.
