There are many causes of high lactate dehydrogenase, such as physiological factors, but also may be caused by heart disease (myocardial infarction, etc.), liver disease (viral hepatitis, cirrhosis, etc.), etc. The causes are different, and the treatments and medications are also different, and you need to use the medications under the guidance of a doctor, and you should avoid using medications on your own to prevent delays in your condition. 1. High lactate dehydrogenase may be caused by mild damage to muscle tissue after strenuous exercise, resulting in high lactate dehydrogenase in the blood, which generally needs no treatment and requires attention to rest, and can generally return to normal on its own. 2. If high lactate dehydrogenase is caused by myocardial infarction, it is necessary to give drugs to dilate coronary arteries, such as nitroglycerin, etc., or give drugs to reduce myocardial oxygen consumption, such as bisoprolol and metoprolol. 3. If high lactate dehydrogenase is caused by viral hepatitis, antiviral drugs such as tenofovir, telbivudine, lamivudine, etc. should be given. If lactate dehydrogenase is high, you should consult a doctor to clarify the cause of the disease, and take treatment under the doctor’s guidance.
