High HDL cholesterol is not harmful and does not cause any harm to a person’s body. HDL cholesterol has a role in preventing the progression of atherosclerosis, so in clinical practice, if the lipoprotein is elevated, it is a sign that the patient is not prone to the problem of coronary angina. Sometimes if a patient has low HDL cholesterol, he or she also needs to take statins in combination to raise HDL cholesterol. Items like total cholesterol, LDL cholesterol, triglycerides, and lipoprotein A are harmful to a person’s body if they are abnormally elevated, for example, they may lead to atherosclerosis, which may lead to fatty liver and pancreatitis, so it is a good sign if a patient has high HDL cholesterol and does not need special treatment.
