Question
My child had myocarditis at the age of 10 and is now experiencing chest tightness and shortness of breath, which has been ongoing for over a week. I want to know if I need to fast before going to the hospital for a cardiac enzyme test?
Answer
A fasting blood test is not necessarily required for a cardiac enzyme test, but it’s best to have the blood drawn on an empty stomach to avoid interference with the results. Strenuous exercise can affect the cardiac enzyme profile, so it’s advisable to avoid vigorous physical activity the day before the blood draw and to ensure adequate rest. Generally, fasting or not has little impact on the cardiac enzyme profile, so the test can be done at any time. I suggest you visit the hospital, undergo a cardiac enzyme six-panel test, an ECG, and a Doppler ultrasound to clarify the condition. The doctor will then develop a treatment plan based on the results.
