PATHOLOGY

Detailed explanation-1: -A heart attack happens when one or more areas of the heart muscle don’t get enough oxygen. This happens when blood flow to the heart muscle is narrowed or blocked. This causes areas of the heart muscle to become damaged or die (infarct). A blood clot is the usual cause of a heart attack.

Detailed explanation-2: -“A heart attack, technically called a myocardial infarction or MI, happens when there is a blockage that prevents the oxygen-rich blood from getting to the heart, ‘’ explains William Harris III, M.D., a cardiologist with Riverside Cardiology Specialists. “Cardiac arrest is when the heart suddenly stops functioning.

Detailed explanation-3: -The rationale for providing supplemental oxygen to a person with AMI is that it may improve the oxygenation of the ischaemic myocardial tissue and reduce ischaemic symptoms (pain), infarct size and consequent morbidity and mortality.
