discomfort in the upper body - arms, shoulder, neck, back
these symptoms can sometimes be different in women.what exactly is a heart attack? most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart. A blockage that is not treated within a few hours causes the affected heart muscle to die.
Gross necrosis of the myocardium, as a result of interruption of the blood supply to the area, as in coronary thrombosis.
Gross necrosis of the myocardium, as a result of interruption of the blood supply to the area.
Necrosis of the myocardium caused by an obstruction of the blood supply to the heart (coronary circulation).
