Drinking large amounts of alcohol over a long period of time, alcohol causes blood vessels to constrict, and blood encounters greater resistance when flowing, thus increasing the burden on the heart and leading to cardiac hypertrophy and hypertension. If the long-term consumption of alcohol reaches more than 50 grams per day for more than 10 years, it will also damage cardiomyocytes and reduce the contractility of the heart, leading to alcoholic cardiomyopathy, causing arrhythmias and cardiovascular insufficiency. In addition, alcohol can accelerate the hardening of blood vessels, leading to coronary atherosclerotic heart disease, which can be complicated by angina pectoris and even myocardial infarction. If a small amount of alcohol is consumed in life, it has a dilating effect on blood vessels and also increases the flow rate of blood circulation appropriately. Alcohol also raises HDL and lowers LDL in the blood, which is also effective in preventing atherosclerosis, so if a small amount of alcohol is consumed in life, it should be beneficial to health. At the same time, it is recommended to try not to drink heavily and drunkenly for a long time.
