Angina pectoris is caused by an acute shortage of blood supply and oxygen to the heart muscle (myocardium). Stable and progressive forms are recognized.
Stable angina shows itself as anginal attacks during walking, physical exertion or strong emotional stress. An attack of stable angina lasts less than 15 minutes; resting quietly and taking 1 nitroglycerin tablet (under the tongue) can help relieve it.
Signs:
Physical exertion
Rise in blood pressure
Attack-like, squeezing, pressing pain that radiates to the left arm, neck and jaw
