Question
A 17-year-old adolescent, who was diagnosed with myocarditis at the age of 10 and has since recovered, has recently been experiencing symptoms of chest discomfort and shortness of breath for over a week. He plans to go to the hospital for a myocardial enzyme test and wants to know if the test needs to be done on an empty stomach in the morning?
Answer
The myocardial enzyme profile test does not necessarily require blood to be drawn on an empty stomach, but to avoid possible interference, it is recommended to have the test done while fasting. Strenuous exercise can affect the myocardial enzyme profile, so it is advised to avoid intense physical activity the day before the test and to ensure adequate rest. Generally, fasting does not significantly impact the results of the myocardial enzyme profile, so the test can be done at any time. It is recommended to visit a hospital for a comprehensive examination, including myocardial enzymes, electrocardiogram, and echocardiogram, to clarify the condition and for the doctor to develop an appropriate treatment plan based on the results.
