Doctors mainly use ICDs to treat ventricular tachycardia and ventricular fibrillation, two life-threatening heart rhythms. The ICD constantly tracks the heart rhythm. When it detects a very fast, abnormal heart rhythm, it delivers an electric shock to the heart muscle to cause the heart to beat in a normal rhythm again.
However, coronary heart disease , or CHD, is actually a result of coronary artery disease, or CAD, said Edward A. Fisher, M.D., Ph.D., M.P.H., an American Heart Association volunteer who is the Leon H. Charney Professor of Cardiovascular Medicine and also of the Marc and Ruti Bell Vascular Biology and Disease Program at the NYU School of Medicine.
Coronary artery disease, also called coronary heart disease, or simply, heart disease, affects millions of Americans. This serious condition is a result of plaque buildup in your arteries. What Is Coronary Artery Disease? The arteries, which start out smooth and elastic, get plaque on their inner walls, which can make them more rigid and narrowed.
This can narrow and decrease or even completely prevent blood flow to part of the heart muscle. If the spasm lasts long enough, it can lead to chest pain (angina) and even a heart attack (myocardial infarction). These spasms are sometimes referred to as Prinzmetal's angina or variant angina.
Also, fatigue can be a normal response to physical and mental activity; in most normal individuals it is quickly relieved (usually in hours to about a day, depending on the intensity of the activity) by reducing the activity. Fatigue is a very common complaint and it is important to remember that it is a symptom and not a disease.
After a heart attack, quick treatment to open the blocked artery is essential to lessen the amount of damage. At the first signs of a heart attack, call for emergency treatment (usually 911). The best time to treat a heart attack is within one to two hours of the first onset of symptoms.
Non-ST segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI) are both commonly known as heart attack. NSTEMI is the less common of the two, accounting for around 30 percent of all heart attacks. NSTEMI, STEMI, and a third condition called unstable angina are all forms of acute coronary syndrome (ACS).

If your heart can’t pump blood well (as is the case with a heart attack), you can feel short of breath. Shortness of breath can sometimes be an accompanying symptom to unusual fatigue in women. For example, some women report they would get unusually short of breath and tired for the activity they were performing.
What is ischemia? Ischemia is a condition in which the blood flow (and thus oxygen) is restricted or reduced in a part of the body. Cardiac ischemia is the name for decreased blood flow and oxygen to the heart muscle. What is ischemic heart disease? It's the term given to heart problems caused by narrowed heart arteries.
ST-segment elevation myocardial infarction (STEMI) is the term cardiologists use to describe a classic heart attack. It is one type of myocardial infarction in which a part of the heart muscle (myocardium) has died due to the obstruction of blood supply to the area.
Other things can help discover an enlarged heart, such as: Your history: Shortness of breath or other symptoms of congestive heart failure may provide clues. A physical exam: You may have swelling. An enlarged heart can also produce abnormal sounds when a doctor listens with a stethoscope.
