Is fasting required for checking cardiac enzymes?

In general, fasting is not required for myocardial enzyme testing. The detailed explanation is as follows:

Myocardial enzymes are a group of enzymes present in heart muscle cells. When heart muscle cells are damaged, these enzymes are released into the bloodstream. By measuring the levels of myocardial enzymes in the blood, doctors can determine whether there is damage to the heart muscle. Since eating generally does not significantly affect the results of myocardial enzyme testing, fasting before the test is usually not necessary. However, if the doctor also needs to perform other tests that require fasting, such as liver function or lipid profile tests, he or she may request the patient to fast in order to avoid multiple visits to the hospital.

Prior to the test, patients should maintain a relatively stable physical condition and avoid strenuous exercise and emotional excitement to ensure the accuracy of the test results.
