What is the difference between an angina and a heart attack?
May 28th, 2010 by admin
angina–which when used alone refers to angina pectoris–is a type of chest pain that is symptomatic of underlying heart problems. It is the direct result of a lack of blood to (or ischemia) an area of the heart muscle (or myocardium), but this ischemia is temporary. A heart attack–technically known as a myocardial infarction–is when a coronary artery in the heart becomes completely occluded and this cuts off the blood supply to a part of the heart muscle permanently. Thus, the essential difference is that angina is temporary and a heart attack is permanent. Both result from ischemia of some area of the myocardium.

Angina is pain due to decreased bloodflow to the heart.
A heart attack is generally a sudden stoppage of flow of blood to the heart.
Angina= partial
Heart Attack = total

Angina means pain from part of the heart not getting enough blood–usually from a narrowed coronary artery. Angina typically does not cause permanent damage to the heart.
A heart attack is when part of the heart is getting NO blood, and starts to die. This causes permanent damage to the heart muscle.

angina is the lack of oxygen to the heart causing it to spasm. a hear attack is when the heart muscle has died and is no longer contracting. they are similar in that angina will almost definitely cause a heart attack.

Angina is a word that means chest pain. It happens when the heart does not get enough oxygen. It can be caused by a myocardial infarction (blockage in the blood supply to the heart). If the heart is without oxygen for long enough it may stop beating (cardiac arrest). Heart attack is a common word that can mean some combination of these things, it is not precisely defined.

it is pain in chest,arms and jaw due to lack of oxygen to the heart muscle mostly during activity and exercise when demand of oxygen is more atherosclerosis and coronary artery spasm are the main cause .it is common in men after the age of 50. patients feels sensation of pressure over chest.it usually starts in the centre of the chest and can spread to throat ,upper jaw,back and arms pain comes on when heart is working harder and requries more oxygen and is relivered by a short rest. there may be nausea,sweating and giddiness.
a prolonged and more serious attack of angia may be due to myocardial infration.
heart attack means
increase in cholestrol in coronary arteries then i leads to heart attack
