Difference Between Angina and Ischemia


Main Difference

Both angina and ischemia are the medical conditions which are closely related to one and another. It won’t be wrong to say that ischemia is one of the major causes of angina. The myocardial ischemia is the medical condition due to the lesser blood supply to the heart. The blockage of blood in ischemia also cuts off the supply of the oxygen to the heart. The person suffering from the ischemia may get chest pain on the left side which engages to the left arm. The inadequate blood supply because of the lack of the blood is known as angina or angina pectoris.

What is Angina?

The angina is the medical condition in which the person faces pain in the chest, and that pain may extend towards the left arm of the person. Angina also named angina pectoris is an initial level pain that lasts for quite some time. The main reason for such pain is the inadequate supply of the blood to the heart. It won’t be wrong to say that ischemia causes angina. The ischemia is the condition of the short supply of the blood and angina comes out as the result of it. Many of the expert physicians term angina pectoris as the mini heart attack as it is often perceived as the alarm of the serious heart issues. In a maximum of the cases angina is nothing more than pain, means it doesn’t lead to the death of the person. Angina indicates the heart trouble at the initial level when the person may undergo the ischemia. The inadequacy of the blood leads to the issues like angina pectoris, which are not much serious if treated at initial level properly. Mainly there are two types of angina, one is stable angina, and the other is unstable angina. Stable angina may be there because of the stress, strenuous physical workout or even due to the exposure to cold weather. On the other hand, unstable angina works opposite to stable angina; it lasts for the more time and does not get cure with the technique used for stable angina.


What is Ischemia?

Ischemia is the heart issue which person suffers through due to the inadequate supply of the blood towards the heart. Consequently, the oxygen flow the heart also gets shortened and lessen the efficiency of the heart. The major cause of the reduced blood supply to the heart muscle is the Coronary Artery Disease (CAD). The decreased blood supply makes the heart muscles less effective, which leads to the chest pain or the pain in the left arm. This chest pain in the scientific terms is recognized as angina pectoris, in which the patient underwent through the severe pain to the parts mentioned above, without actually knowing the cause of the pain. As mentioned above CAD is the most common cause of the disease; in this, the narrowing of the arteries takes place, which results in less blood supply to the heart muscle. At the same time, arteries losses their elasticity which leads to a more crucial condition of the blood supply to the heart muscle. All the narrowing and elasticity loss takes place due to the fat deposition on the walls of arteries. This fat deposition is the cholesterol aggregation, which is termed as atherosclerosis in the scientific language. This blockage condition not treated immediately can even lead to the myocardial infarction. Other than fat deposition, hypertension, diabetes mellitus, lack of exercise, and chewing tobacco are few of the prominent factors which cause ischemia.

Angina vs. Ischemia

  • Angina is the pain in the chest which may extend to the arm of the person. On the other hand, ischemia is the health condition caused due to the inadequate supply of the blood.
  • Ischemia is the condition of the inadequate supply of the blood and oxygen, whereas angina is mainly caused due to the ischemia.
