Angina is the very short term lack of blood flow to the heart with no tissue death. Myocardial infarction is the complete lack of oxygen to the heart muscle and the muscle tissue death.
Np. Angina refers to chest pain, such as from vasospasm of the coronary arteries, or from an impending myocardial infarction. The term, myocadial infarction, refers to cardiac muscle damage and death (a small MI involving a small area of the heart, and a large MI involving a larger portion of the heart).
Angina is chest pain due to ischemia (a lack of blood, thus a lack of oxygen supply and waste removal) of the heart muscle, generally due to obstruction or spasm of the coronary arteries (the heart's blood vessels). Myocardial Infarction is cellular death of the heart muscle due to lack of oxygen, often caused by blockage of arteries. Essentially angina proceeds a myocardial infarction, both are caused by low/no oxygen reaching some part of the heart
The pain of angina pectoris and myocardial infarction is sometimes referred to the head and neck region. The mechanism for this effect remains obscure. A case is presented here that reports that electrical stimulation of a cardiac branch of the left vagus nerve in humans can cause referred craniofacial pain. This leads to the hypothesis that the vagus nerve plays a role in mediating this pain.
A myocardial infarction (MI) is caused by inadequate oxygen supply to the heart. MI's can be caused by numerous events. The most common type of MI's are caused by blockages in the coronary arteries, which solely supply the heart muscle. This can be due to a thrombosis (a clot formed at the location) or an embolism (a clot or matter that has traveled through the system and lodges at the location).Other causes of chest pain that may lead to an MI include coronary artery spasm and angina. Although usually temporary and do not cause any damage, chest pain associated with angina or coronary artery spasm must be diagnosed by a doctor.
Myocardial ischemia is the medical term meaning inadequate oxygen to the heart. If it is prolonged, it may result in myocardial infarction (heart attack), which is tissue damage due to lack of blood flow. During the period of inadequate oxygen delivery, a person may feel crushing chest pain called "angina pectoris."
