Angina symptoms include a radiating chest pain, nausea, fatigue, and pain in the arms, legs or back, according to MedicineNet.com. Other symptoms include shortness of breath, weakness and sweating.
Anginas are classified as either stable or unstable, as noted by Mayo Clinic. A stable angina tends to occur during events that cause the heart to work harder, such as exercise, and the pain symptoms of a stable angina last only a few minutes, subsiding upon rest. An unstable angina is more serious and characterized by a different pattern of pain that is unexpected and occurs even while resting. It tends to last as long as 30 minutes and could be a precursor to a heart attack. An unstable angina is an emergency that requires immediate medical attention.
Treating an angina depends on the scope and severity of the attack, and the underlying objective is to reduce the severity of symptoms and reduce the risk of heart attack, explains Mayo Clinic. Treatment options include lifestyle changes, such as quitting smoking, losing weight, eating smaller meals and exercising. Medications, such as nitrates, aspirin, statins and beta-blockers, help alleviate symptoms when lifestyle changes are not sufficient. In severe cases, surgical procedures may be necessary, including angioplasty, stenting and bypass surgery.
