Angina, also known as angina pectoris, is chest pain or pressure, usually caused by insufficient blood flow to the heart muscle (myocardium). [2] It is most commonly a symptom of coronary artery disease. [2] Angina is typically the result of partial obstruction or spasm of the arteries that supply blood to the heart muscle. [3]
Usually the pain and symptoms last less than 20 minutes and subside after the exertion or stress is taken away, and therefore the heart muscle isn’t demanding as much blood. Now, unlike stable angina which describes when patients have pain only during periods of exertion or stress, but not during rest, there is also unstable angina which is ...
Certain individuals such as women, diabetics, and the elderly may present with more varied symptoms. [8] If blood flow through the coronary arteries is stopped completely, cardiac muscle cells may die, known as a myocardial infarction, or heart attack. [9] Coronary artery disease (CAD) is the most common cause of coronary ischemia. [7]
The resultant reduction in the heart's blood supply due to atherosclerosis in coronary arteries "causes shortness of breath, angina pectoris (chest pains that are usually relieved by rest), and potentially fatal heart attacks (myocardial infarctions)". [36]
Chest pain may present in different ways depending upon the underlying diagnosis. Chest pain may also vary from person to person based upon age, sex, weight, and other differences. [1] Chest pain may present as a stabbing, burning, aching, sharp, or pressure-like sensation in the chest.
In contrast to those with angina secondary to atherosclerosis, people with variant angina are generally younger and have fewer risk factors for coronary artery disease with the exception of smoking, which is a common and significant risk factor for both types of angina. Affected people usually have repeated episodes of unexplained (e.g., in the ...
The lawsuit, filed on March 19 in U.S. District Court in Southern Florida, accused Stephanopoulos of making the statements with malice and a disregard for the truth. It said the statements were ...
Not only does this affect supply to the heart muscle itself, but it also can affect the ability of the heart to pump blood throughout the body. Therefore, any disorder or disease of the coronary arteries can have a serious impact on health, possibly leading to angina , a heart attack , and even death.
