Dr. Viveka Kumar, Senior Director - Cath Lab, Max Super Speciality Hospital, Saket, will explain the use of aspirin in acute MI, in this video. Aspirin reduces the mortality and event rates by 22% in acute MI settings. If even there is a clinical diagnosis which is not proven by ECG, the patient is given aspirin. If the patient has pain which lasts for 15-20 minutes, then it is typical angina pain which is crushing chest pain. The patient should immediately take aspirin and when the diagnosis is confirmed, clopidogrel or ticagrelor is added and the patient is shifted for primary PCI.
