Stable angina occurs during exertion, can be quickly relieved by resting or taking nitroglycerine, and lasts from 3 to 20 minutes.
Nitroglycerin is the classic treatment for angina.
Unstable angina, which increases the risk of a heart attack, occurs more frequently, lasts longer, is more severe, and may cause discomfort during rest or light exertion.
The prevalence of angina pectoris is nearly seven million Americans according to The American Heart Association.
angina pectoris meanind a syndrome characterized by paroxysmal, constricting pain below the sternum, most easily precipitated byexertion or excitement and caused by ischemia of the heart muscle, usually due to a coronary arterydisease, as arteriosclerosis
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
People with angina are at risk of having a heart attack.
Myocardial ischemia is owing to poor blood supply and infarction is due to no blood supply. The severity of both differs and ischemia can progress to infarction.
Angina pectoris, but everyone just calls it angina
Deficient blood supply to the myocardium is: ischemia Ischemia is the medical terms for deficient blood supply to the myocardium. The suffix -emia denotes a blood condition; ischem/o means to hold back. With occlusion from atherosclerosis, the blood flow is restricted, resulting in deficient blood supply.
Usually a stenotic coronary artery caused by atherosclerosis. The stenotic (narrowed) artery can give a brief period of ischemia (withholding of blood) to a region of the heart, which is felt as an intense pain. Angina pectoris is a sign that a more serious episode of ischemic attack can happen for that artery. If it is left untreated, it is very likely that the artery will eventually become completely clogged and the ensuing prolonged ischemia will cause a myocardial infarction (i.e. heart attack).
Intestinal ischemia is indirectly due to heredity. The condition is caused by the narrowing or blocking of an artery, and one of the reasons this may happen is due to cholesterol buildup. Since high cholesterol is at least partly due to heredity, intestinal ischemia can be thought of as inheritable.
Inferoapical ischemia is lack of blood flow below the apex.
