  • subsequent type 1 myocardial infarction

Clinical Information

  • A disorder characterized by gross necrosis of the myocardium; this is due to an interruption of blood supply to the area.
  • Coagulation of blood in any of the coronary vessels. The presence of a blood clot (thrombus) often leads to myocardial infarction.
  • Complete blockage of blood flow through one of the coronary arteries, usually from coronary atherosclerosis.
  • Each year over a million people in the United States Have a heart attack. About half of them die. Many people have permanent heart damage or die because they don’t get help immediately. It’s important to know the symptoms of a heart attack and call 9-1-1 if someone is having them. Those symptoms include
    • chest discomfort – pressure, squeezing, or pain
    • shortness of breath
    • discomfort in the upper body – arms, shoulder, neck, back
    • nausea, vomiting, dizziness, lightheadedness, sweating
    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).
