Typical angina is aggravated by physical activity or emotional stress and is relieved by rest or nitroglycerin. [4] The pain may radiate to other parts of the body, most commonly the left arm or neck. [7] In some individuals, the pain may be less severe and present as pressure or numbness. [7]
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]
The accepted management of unstable angina and acute coronary syndrome is therefore empirical treatment with aspirin, a second platelet inhibitor such as clopidogrel, prasugrel or ticagrelor, and heparin (usually a low-molecular weight heparin), with intravenous nitroglycerin and opioids if the pain persists.
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. [3]
What not to do: Don’t stop rescue efforts until the person starts breathing, a pro rescuer takes over, the scene becomes unsafe, or you’re alone and become too exhausted to keep going.
The relatively narrow coronary arteries are commonly affected by atherosclerosis and can become blocked, causing angina or a heart attack. The coronary arteries are classified as "terminal circulation", since they represent the only source of blood supply to the myocardium; there is very little redundant blood supply, that is why blockage of ...
Every 40 seconds, someone in the U.S. has a heart attack. Heart disease is the leading cause of death for women and men, according to the Centers for Disease Control and Prevention.
