Clinical Information
- A disorder characterized by substernal discomfort due to insufficient myocardial oxygenation.
- A heart condition marked by paroxysms of chest pain due to reduced oxygen to the heart.
- Angina is chest pain or discomfort you get when your heart muscle does not get enough blood. It may feel like pressure or a squeezing pain in your chest. It may feel like indigestion. You may also feel pain in your shoulders, arms, neck, jaw or back. Angina is a symptom of coronary artery disease (cad), the most common heart disease. Cad happens when a sticky substance called plaque builds up in the arteries that supply blood to the heart, reducing blood flow.there are three types of angina: stable, unstable and variant. Unstable angina is the most dangerous. It does not follow a pattern and can happen without physical exertion. It does not go away with rest or medicine. It is a sign that you could have a heart attack soon.not all chest pain or discomfort is angina. If you have chest pain, you should see your health care provider.
- Chest pain caused by coronary heart disease
- Previous or current symptoms described as chest pain or pressure, jaw pain, arm pain, or other equivalent discomfort suggestive of cardiac ischemia. (nih roadmap cardiovascular data standards working group)
- Recurring thoracic pain or discomfort which occurs when a part of the heart does not receive enough blood; usually caused by exertion or excitement.
- The symptom of paroxysmal pain consequent to myocardial ischemia usually of distinctive character, location and radiation. It is thought to be provoked by a transient stressful situation during which the oxygen requirements of the myocardium exceed that supplied by the coronary circulation.

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.
