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
- 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).
- Necrosis of the myocardium, as a result of interruption of the blood supply to the area. It is characterized by a severe and rapid onset of symptoms that may include chest pain, often radiating to the left arm and left side of the neck, dyspnea, sweating, and palpitations.
