Angina pectoris is a series of symptoms caused by ischemia and hypoxia of the heart due to narrowing or spasm of the coronary arteries. It is generally a squeezing, tightening and cramping sensation in the back of the sternum and the back of the chest, which radiates to the left shoulder, the left arm, and even to the pinky and ring fingers of the left hand, and in severe cases, it can also radiate to the lower jaw and the root of the ear. Angina can also spread to the abdomen, and the patient will have abdominal pain characterized by gastrointestinal colic, similar to gastrointestinal spasms, especially after satiety, abdominal pain, abdominal distension, and even nausea and vomiting. The abdominal pain is cyclical and is mostly relieved by giving systematic massage or oral nitroglycerin after satiety and in cold weather.
