Myocardial zymogram can be checked urgently, such as acute myocardial infarction, myocarditis, etc., but if the condition permits, the patient should preferably have an empty stomach before the examination, and do not eat or drink water for at least four or five hours. Because after eating and drinking water, the secretion of bile and pancreatic juice in the digestive system is strong, which may lead to the increase of enzymes in some serum, thus affecting the real test results of patients. In addition, the first two days of the examination, do not drink or eat meat, pay attention to light diet, pay attention to rest, and avoid strenuous exercise and overwork. Because of the excessive activity of skeletal muscle, some enzymes will be released into the human blood, which can also lead to the abnormality of some indicators and affect the myocardial zymography.
