Stable angina is a symptom of heart disease. It is usualy precipitated by exertion or emotional stress, and exacerbated by having a full stomach or cold temperatures (the "4 Es": exertion, emotion, eating and extreme temperature).
An attack usually comes on with a sudden seizure of pain, felt at first over the region of the heart, but radiating through the chest in various directions, and frequently extending down the left arm. A feeling of constriction and of suffocation accompanies the pain, although there is seldom actual difficulty in breathing.
When the attack comes on, as it often does, in the course of some bodily exertion, the sufferer is at once brought to rest, and during the continuance of the paroxysm experiences the most intense agony.The countenance becomes pale, the surface of the body cold, the pulse feeble, and death appears to be imminent, when suddenly the attack subsides and complete relief is obtained.
Stable Angina can be treated by taking a nitroglycerine either prior to a period of known exertion or by taking the nitroglycerine during the actual angina attack.
