Myocardial Infarction is the sudden death of cardiac muscle cells caused by the lack of blood supply for a prolonged period of time. The lack of blood flow can occur because of many different factors but is usually related to a blockage in one or more of heart’s arteries. Without blood flow, the affected heart muscle will begin to die. If blood flow isn’t restored quickly, a heart attack can cause permanent heart damage and death.
Signs and symptoms include radiating chest pain, unrelieved by rest, sweating, difficulty breathing, increased heart rate and blood pressure,, nausea and vomiting and anxiety.
First line edications used in myocardial infarction include aspirin, oxygen therapy, nitroglycerin and morphine. the other medications used are antithrombotics, antiplatelets, ACE inhibitors, beta blockers, angiotensin receptor blockers, cholesterol lowering agents and calcium channel blockers.
Diagnosis is performed by ECG and angiography.
