The area of infarct is set(p) by the coronary that is affected and by its distribution of blood operateAsprin administered immediately on recognition of myocardial infarction (MI ) sign and symptoms has greatest men d on the reduction of MI death rate . aspirin prevents additional platelet activation and interferes with platelet hamper and coherence in the atheromatous plaqueMorphine is given often intravenously to resign the excruciating pain that is sometimes unbearable by the patient . It has advantage over other pain killers as it has quick onset of action and the intravenous route does not elevate serum enzymesThe foundation for Oxygen use is the self-reliance that haemoglobin present in red blood cells exit be saturated to maximum carrying capacity Arterial blood that is at its utmost oxygen-carrying capacity can potentially hex oxygen to myocardium in jeopardy during a MI by way of life of the collateral coronary circulation (Sue E .
