Different mechanisms may be in effect difference between na and aa depending on the dose, duration, and pattern of alcohol consumption. 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.
These studies also support the favorable effect of moderate and the harmful effect of heavy drinking on large arteries. Data derived from systematic reviews and meta-analyses suggest that alcohol-dose and CV-health relationships differ for various CV conditions. For example, certain levels of alcohol consumption that lower risk for CHD may increase it for other CV conditions, such as stroke. In addition, data from studies using new research methods, including Mendelian randomization, suggest that the relationship between low-to-moderate alcohol consumption and cardioprotection merits more critical appraisal (Holmes et al. 2014).
That means, if you’re living with other medical conditions and/or taking certain medications, this will all have an impact on how alcohol affects you. These usually come with a warning sticker from your pharmacy that tells you not to drink while you take them. One drink is 12 ounces of beer or wine cooler, 5 ounces of wine, or 1.5 ounces of 80-proof liquor.
So far, the strongest evidence with heart health has shown that alcohol can increase levels of HDL (good) cholesterol. HDL works to keep LDL (bad) cholesterol from clogging your arteries by moving it to the liver, where it’s broken down and removed from the body. Many studies have found that the combination of high HDL and low LDL levels protects against heart attacks and stroke.
„However, this is not the most important factor in preventing heart disease, and there are other ways to increase HDL than drinking alcohol, such as regular exercise,” says Dr. Gaziano. The relationship between alcohol consumption and total cerebrovascular disease is generally J-shaped, although it differs according to subtypes of stroke 105, 116 (Figure 5). A positive linear relationship has been observed between the level of alcohol consumption and risk of brain or subarachnoid hemorrhage.8, 110, 116, 117 Actions on the BP and blood coagulation system seem to be underlying mechanisms for this adverse influence of alcohol. The reasons for the inconsistent results in experimental studies are not clear, but cannot be explained by differences in daily doses of alcohol administration. The periods of alcohol administration, however, are generally longer in studies showing BP reduction than those showing BP elevation.
- This suggests that alcoholic beverage type may be an important mediator, because in countries such as Russia, spirits are the alcoholic beverage of choice.
- In hospital, your medications are adjusted to control your blood pressure, but you aren’t drinking alcohol at that time.
- Aside from the immediate influence on appetite that comes from alcohol consumption, there are also effects on energy storage.
- According to 2022 research, any amount of alcohol can have a negative impact on the heart and cardiovascular system.
How Much Alcohol Is Too Much?
Not surprisingly, alcohol consumption has complex and varying effects on platelet function. Studies using different methodologies have shown that low-to-moderate alcohol consumption decreases platelet activation and aggregation in certain cases—for example, in response to certain physiologic stimuli such as adenosine 5′-diphosphate (Salem and Laposata 2005). On the other hand, significant daily alcohol consumption increases platelet aggregation and reactivity.

High triglyceride levels in the blood stream have been linked to atherosclerosis and, by extension, increased risk of CHD and stroke. 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. Interestingly, the researchers found a nonlinear effect of alcohol consumption on HDL2-c levels.
Neurohormonal actions of alcohol
In the moment, alcohol can help people feel relaxed, and that’s especially true when people drink in social situations. It’s possible that light to moderate drinkers have stronger social ties, which in turn provide resilience against stress. The study authors are now focusing on other interventions — such as meditation or exercise — that might lower the brain’s stress activity without the potentially harmful effects of alcohol.
On the other hand, alcohol may act to prevent atherosclerosis and to decrease the risk of ischemic heart disease, mainly by increasing HDL cholesterol and inhibiting thrombus formation. A J- or U-shaped relationship has been observed between the level of alcohol intake and risk of cardiovascular mortality and total mortality. It is reasonable to reduce the alcohol intake to less than 30 ml per day for men and 15 ml per day for women in the management of hypertension. As a small amount of alcohol seems to be beneficial, abstinence from alcohol is not recommended to prevent cardiovascular disease. Several experimental studies have been conducted to examine the short-term effect of alcohol intake on feeding behavior and appetite control 3•, 5.
