From this article you will learn: the positive effect of alcohol on the heart is a myth or the truth, what cardiovascular diseases are associated with alcohol abuse, what is the maximum amount of alcohol-containing products allowed to drink to women and men.
How much alcohol can be safely consumed
For many years, it has been argued that drinking alcohol has a beneficial effect on the heart. It serves as an excuse for many people who drink alcohol in large quantities.
Scientific evidence suggests that ethanol does have some useful properties for the cardiovascular system. However, a prerequisite for the emergence and preservation of these positive properties is moderation in the use of alcoholic beverages. If you drink them constantly and in large quantities, it can cause many heart diseases.
Therefore, people who do not drink alcohol, start using it in order to improve the health of the cardiovascular system, doctors categorically do not recommend.
On how alcohol affects the heart, you can consult a cardiologist or a narcologist.
How much alcohol can be safely consumed
Doctors recommend that men consume no more than 2 standard doses of alcoholic beverages per day, and women not more than 1 standard dose per day.
Under the standard dose is meant that amount of alcoholic beverage, which contains 14 grams of pure ethyl alcohol. This amount is contained in:
- 360 ml of light beer, having a 5% strength;
- 150 ml of wine with a strength of 12%;
- 45 ml of vodka with a strength of 40%.
How alcohol harms the cardiovascular system
Alcohol can harm the heart and the blood vessel. At the time of use, a temporary increase in heart rate( heart rate) and blood pressure( BP) is possible. Chronic abuse of alcohol can lead to constant tachycardia, hypertension, heart rhythm disturbance and weakening of the heart muscle. All these consequences of consumption increase the risk of heart attack and stroke.
Negative effects of alcohol on the heart:
Increased heart rate
Alcohol can cause heart rate variability, that is, changes the time between contractions of the heart muscle. Scientific research has found that regular abuse of alcohol can cause tachycardia. With regular episodes of increased heart rate, various complications can be associated - for example, the formation of thrombi, which are dangerous for the development of myocardial infarction or stroke.
Increased blood pressure
Episodic drinking can lead to a temporary increase in blood pressure, and regular abuse causes permanent hypertension. Alcohol product increases blood pressure by many mechanisms, and scientific data show that stopping the use of alcohol can reduce its level. Increased blood pressure can cause thickening and thickening of the walls of the arteries, as well as a risk factor for myocardial infarction and stroke. Scientific studies have found that the use of more than two standard doses of alcohol causes an immediate increase in blood pressure.
Heart muscle weakness
Abuse of alcohol can cause cardiomyopathy - damage to the heart muscle. Most often, alcoholics develop dilated cardiomyopathy, in which all chambers of the heart increase in size, and its walls become thinner. This disease leads to congestive heart failure, in which the body can not effectively pump the blood through the body.
Heart Disease Disorders
Alcohol can cause acute heart rhythm disturbances, most often - atrial fibrillation( AF).In AF, the myocardium of the upper chambers of the heart( atria) is reduced uncoordinated. Alcohol causes disturbances in the heart rhythm due to both acute and chronic effects on the heart. With AF, blood stagnation occurs in the left atrium, which can lead to the formation of thrombi in the body cavity. This increases the risk of thromboembolic complications, such as ischemic stroke, for example.
In addition to the negative effect directly on the heart, the abuse of alcohol can cause other effects affecting the health of the cardiovascular system:
- Increased amount of fats in the blood.
- Increased risk of developing diabetes, which then affects the heart and blood vessels.
The beneficial effects of alcoholic beverages on the heart of
There is scientific evidence that a moderate amount of alcohol can be beneficial for the cardiovascular system. For example, the use of 2 standard doses per day can reduce the risk of cardiovascular disease by 50%.It is believed that the most useful is red wine.
The main positive effects:
- Increase in the level of useful cholesterol in the blood and reduction of atherosclerotic plaques in the arteries.
- Alcohol can act as an anticoagulant, that is, it dilutes blood. Due to this action, the probability of myocardial infarction decreases.
- Alcohol reduces the spasm of the coronary arteries that occurs during stress.
- Alcohol can reduce insulin levels and raise estrogen levels in the blood.
- Alcohol enhances blood flow through the coronary arteries.
However, doctors do not recommend starting to drink alcohol in order to get their positive effect on the heart. These same effects can be achieved with the help of healthy nutrition, physical activity, weight normalization and other changes in lifestyle. Moreover, the negative effect of alcohol on other organs outweighs its positive effect on the cardiovascular system.
How to avoid the negative influence of alcohol on the heart
If a person wishes to avoid the negative effects of alcohol on the heart, he should remember the following tips:
- Drink alcohol only in recommended safe quantities.
- If you have ever had problems with drinking, you are strictly prohibited from drinking.
- If you have high blood pressure, alcoholic foods should be treated with extreme caution. Doctors recommend completely abandoning their use, until the blood pressure is normalized.
- If you notice that you can not stop in time when drinking alcohol, you should completely abandon them.
- Patients with cardiovascular diseases should remember that for them alcohol and heart are incompatible.
