There is a relationship between heart disease and alcohol consumption, and clinically alcoholic cardiomyopathy is caused by alcohol consumption; for other diseases, alcohol is restricted because heavy alcohol consumption can cause ischemia and hypoxia in the heart muscle, which can also aggravate the heart condition. Alcoholic cardiomyopathy is a condition in which people who drink a lot of alcohol over a long period of time and on a daily basis, and who develop alcohol dependence, can develop some manifestations similar to dilated cardiomyopathy, called alcoholic cardiomyopathy. Alcoholic cardiomyopathy is characterized by myocardial fibers and interstitial edema, as well as fibrosis, mitochondrial degeneration, and other symptoms, such as enlarged heart chambers, shortness of breath, or even seated breathing, edema, hepatomegaly, and heart failure. There are also corresponding signs, such as X-rays and electrocardiograms, which can reveal left ventricular hypertrophy and enlarged heart chambers. Ultrasound can find enlarged ventricles, reduced ejection fraction, and other cardiomyopathies need to be excluded. Combined with a history of heavy drinking, such as 4 bottles of beer and 150g of liquor per day for more than 10 years, alcoholic cardiomyopathy can be considered and good results can be achieved by abstaining from alcohol and treatment. In addition, heavy alcohol consumption can lead to alcoholism of the liver and brain.
