What is an angina attack?
In layman's term, angina pectoris means (severe) chest pain due to the lack of blood and oxygen supply of the heart (ischemia). The chest pain is not more than 10-15 minutes. It can be described as a feeling of tightness or squeezing and can radiate to the neck area, shoulder and arm, (particularly the left), and even the epigastrium. It is usually relieved by rest, and nitroglycerin.
