Angina vs. Ischemia — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on May 16, 2024
Angina refers to chest pain due to reduced blood flow to the heart, while ischemia is a broader term for inadequate blood supply to tissues, causing various symptoms including angina.

Key Differences
Angina is characterized by chest pain or discomfort caused by reduced blood flow to the heart muscle. This condition is typically a symptom of an underlying heart problem, most commonly coronary artery disease. Ischemia, on the other hand, refers to a reduction in blood supply to any tissue, not just the heart. It can affect various organs and tissues, leading to different symptoms depending on the area impacted.
While angina specifically indicates heart-related pain due to ischemia, ischemia itself can occur in any part of the body and is not limited to causing pain. It can result in dysfunction or damage to the tissues involved. Angina is thus a specific manifestation of cardiac ischemia.
Angina typically results from blockages or narrowing in the coronary arteries, leading to decreased oxygen supply to the heart muscle. This condition can be stable or unstable, with stable angina being predictable and occurring with exertion, whereas unstable angina is unpredictable and more dangerous.
Ischemia involves a broader range of causes, including blockages in any arteries, blood clots, or severe blood loss, which reduces the oxygen and nutrient supply to tissues. It can occur suddenly or develop gradually, depending on the underlying cause and severity.
In summary, angina is a symptom related to heart ischemia, presenting as chest pain, while ischemia is a general condition describing reduced blood flow to any part of the body, potentially leading to various symptoms depending on the affected tissue.

Chronic ischemia may require long-term treatment.
Angina
Chest pain from heart blood flow reduction.
He felt a sharp angina attack after climbing the stairs.
Ischemia
Lack of oxygenated blood to organs.
Ischemia can result from a blood clot.
Angina
Angina, also known as angina pectoris, is chest pain or pressure, usually due to insufficient blood flow to the heart muscle. Angina is usually due to obstruction or spasm of the arteries that supply blood to the heart muscle.
Ischemia
Ischemia or ischaemia is a restriction in blood supply to tissues, causing a shortage of oxygen that is needed for cellular metabolism (to keep tissue alive). Ischemia is generally caused by problems with blood vessels, with resultant damage to or dysfunction of tissue i.e.
Angina
Angina pectoris.
Ischemia
A decrease in the blood supply to a bodily organ, tissue, or part caused by constriction or obstruction of the blood vessels.
Angina
A condition, such as severe sore throat, in which spasmodic attacks of suffocating pain occur.
Ischemia
Local disturbance in blood circulation due to mechanical obstruction of the blood supply (for example, embolism, thrombosis, or vasoconstriction).
Angina
(pathology) An inflammatory infection of the throat, particularly quinsy.
Ischemia
Local anemia in a given body part sometimes resulting from vasoconstriction or thrombosis or embolism
Angina
(pathology) angina pectoris
Angina
A chest pain or shortness of breath occurring with lesser degrees of arterial blockage.
Angina
Any inflammatory affection of the throat or faces, as the quinsy, malignant sore throat, croup, etc., especially such as tends to produce suffocation, choking, or shortness of breath.
Angina
Any disease of the throat or fauces marked by spasmodic attacks of intense suffocative pain
Angina
A heart condition marked by paroxysms of chest pain due to reduced oxygen to the heart
Common Curiosities
What are the symptoms of angina?
Symptoms include chest pain, pressure, or squeezing, often triggered by physical activity.
What causes ischemia?
Ischemia is caused by blockages in arteries, blood clots, or severe blood loss.
Can ischemia occur in parts of the body other than the heart?
Yes, ischemia can affect any tissue, including the brain, limbs, and organs.
What are the types of angina?
Angina can be stable, occurring predictably with exertion, or unstable, occurring unpredictably.
What treatments are available for angina?
Treatments include medication, lifestyle changes, and procedures to improve blood flow.
What is the difference between angina and a heart attack?
Angina is chest pain due to reduced blood flow, whereas a heart attack is severe ischemia causing heart muscle damage.
What is angina?
Angina is chest pain due to reduced blood flow to the heart.
How does ischemia affect tissues?
Ischemia reduces oxygen and nutrient supply, causing pain, dysfunction, or tissue damage.
What is stable angina?
Stable angina is predictable chest pain triggered by exertion and relieved by rest.
How is angina related to ischemia?
Angina is a specific type of ischemia affecting the heart, causing chest pain.
Can ischemia lead to a heart attack?
Yes, severe ischemia can cause myocardial infarction, commonly known as a heart attack.
What is unstable angina?
Unstable angina is unpredictable chest pain, occurring at rest and indicating a higher risk of heart attack.
How is ischemia diagnosed?
Diagnosis involves imaging, blood tests, and monitoring symptoms specific to the affected area.
Can ischemia be chronic?
Yes, ischemia can be chronic, requiring long-term management to prevent complications.
How can ischemia be prevented?
Prevention involves managing risk factors like high blood pressure, cholesterol, and avoiding smoking.
