===Cardiac Markers===
Cardiac markers are essential for confirming the diagnosis of infarction. Elevated CK MB and Troponin I indicate damage of the myocardium. It can however take 4-8 hours, after the symptoms started, before the cardiac markers are elevated.  The advise is to repeat the measurements after 4-6 hours. A pitfall concerning elevated Troponin I can be patients with renal failure or pulmonary embolism. Although cardiac markers are helpful for confirming the diagnosis reperfusion should not always wait till the cardiac markers are known.
