Question
A 17-year-old adolescent, who had myocarditis at the age of 10 and has recovered, recently experienced symptoms of chest discomfort and shortness of breath that have persisted for over a week. The parent wants to know if a fasting blood draw is necessary in the morning for a cardiac enzyme test?
Answer
A fasting blood draw is not necessarily required for a cardiac enzyme profile test, but to avoid potential interference, it is recommended to have the blood test done on an empty stomach. Additionally, strenuous exercise can potentially affect the cardiac enzyme profile, so it is advised to avoid intense physical activity and ensure adequate rest the day before the blood draw. Generally, fasting does not significantly impact the results of the cardiac enzyme profile, so the test can be done at any time. It is recommended to visit a hospital for a consultation, and undergo tests such as cardiac enzymes six, electrocardiogram, and echocardiogram to clearly determine the condition, and for the doctor to formulate an appropriate treatment plan based on the results of the examination.
