When the episode of ischemia lasts for a longer period of time, heart muscle cells die. This is called a heart attack or myocardial infarction. That is why it is critical to recognize ischemia on the ECG in an early stage. WebCardiac enzymes are superior to ECG in the diagnosis of AMI. Myoglobin, FABP, and GPBB are early biomarkers in the diagnosis of AMI. TnT and TnI are late markers. CK-MB is a remarkable AMI biomarker in the first 10–12 hours.
