Final answer:
An MI is performed in patients with cocaine-induced transmural ischemia (ST elevation) to check for any coronary thrombus. This helps assess the extent of damage and determine appropriate treatment options for a heart attack.
Step-by-step explanation:
An MI (Myocardial Infarction) is performed in patients with cocaine-induced transmural ischemia (ST elevation) to check for any coronary thrombus. An MI is commonly referred to as a heart attack, which occurs when there is a lack of blood flow to the heart muscle due to a blockage in the coronary arteries. Performing an MI helps assess the extent of damage to the heart and determine appropriate treatment options such as administering clot-dissolving medications (thrombolytics), using anticoagulants, or performing angioplasty and stenting to open blocked blood vessels.
