What is the primary action of thrombolytics in an acute myocardial infarction?

Explanation:
The main action of thrombolytics in an acute myocardial infarction is to dissolve the clot that’s blocking a coronary artery. They activate plasminogen to plasmin, and plasmin digests fibrin to break down the thrombus, restoring blood flow to the affected part of the heart. This reperfusion limits myocardial damage if given within the recommended time window. These drugs do not lower cholesterol, they do not strengthen or harden clots (they promote clot dissolution), and they do not prevent infection. Keep in mind the bleeding risk, including intracranial hemorrhage, and contraindications such as active bleeding or recent major surgery.
