The types of wine can be basically divided into three categories according to their properties, namely fermented wine, distilled wine and mixed beverage wine (hereinafter referred to as mixed wine):

(1) Fermented wine refers to low-alcohol wine made from grains and fruit juice, including wine, beer, yellow wine and fruit wine.

(2) Distilled liquor refers to highly distilled liquor distilled from the above-mentioned fermented raw liquor or fermented mash and fermented grains, including China liquor, French brandy, whisky, Dutch gin, vodka, rum and tequila.

(3) The preparation of beverage wine takes fermented raw wine or distilled wine as the main raw material, with certain color, aroma and taste raw materials, and is made through the specified technological process. Including cocktails, liqueurs, medicinal liquor, etc.

Long-term heavy drinking will lead to heart failure, which is characterized by enlarged ventricles and low left ventricular systolic function. The appearance and regression of pathological changes are related to drinking. After stopping drinking, heart failure can be improved or at least not further deteriorated, and it will recur after drinking again. If this happens repeatedly, it will cause irreversible damage to the myocardium, even after abstinence, there will be progressive deterioration of cardiac function, which will lead to "alcoholic cardiomyopathy".

In addition, the incidence of atrial fibrillation in alcoholics is also high. This kind of atrial fibrillation caused by alcoholism can be reversed or stabilized if alcohol can be stopped early. Alcohol is a food with pure heat energy. Long-term heavy drinking will increase weight, affect the process of glucose metabolism in the body and increase the production of triglycerides. Obesity and hyperlipidemia are both risk factors for coronary heart disease. Therefore, long-term heavy drinking will increase the prevalence and mortality of coronary heart disease in heavy drinkers.
