Right Coronary Artery Ischemia

Right Coronary Artery Ischemia is a medical condition where there is a lack of blood flow to the heart muscle due to narrowing or blockage of the right coronary artery. This can lead to serious complications, including heart attack or even death if not treated promptly. In simple terms, it means there isn’t enough oxygen-rich blood reaching part of the heart muscle.

Types of Right Coronary Artery Ischemia:

There are mainly two types:

1. Acute Right Coronary Artery Ischemia: This occurs suddenly and requires immediate medical attention.
2. Chronic Right Coronary Artery Ischemia: This develops gradually over time and may cause persistent symptoms.

Causes of Right Coronary Artery Ischemia:

1. Atherosclerosis: Build-up of plaque in the arteries, restricting blood flow.
2. Coronary artery spasm: Temporary tightening of the artery, reducing blood flow.
3. Blood clot: Obstruction in the artery due to a clot formation.
4. Coronary artery dissection: Tear in the artery wall causing a blockage.
5. Coronary artery embolism: Blocking of the artery due to a traveling clot.
6. Coronary artery vasculitis: Inflammation of the artery walls affecting blood flow.
7. Coronary artery compression: External pressure on the artery, reducing blood flow.
8. Coronary artery trauma: Injury to the artery, leading to reduced blood supply.
9. Coronary artery anomalies: Structural abnormalities affecting blood flow.
10. Drug-induced: Certain medications can cause constriction of the arteries.
11. Hypertension: High blood pressure can damage the artery walls.
12. Diabetes: Increases the risk of atherosclerosis and narrowing of arteries.
13. Obesity: Excess weight can contribute to the development of atherosclerosis.
14. Smoking: Tobacco use damages the arteries and promotes plaque formation.
15. High cholesterol: Elevated levels of cholesterol can lead to plaque buildup.
16. Sedentary lifestyle: Lack of physical activity increases the risk of artery narrowing.
17. Stress: Chronic stress can contribute to high blood pressure and arterial damage.
18. Genetic predisposition: Family history of heart disease increases the risk.
19. Age: Risk increases with advancing age.
20. Uncontrolled hypertension: Persistent high blood pressure can damage arteries over time.

10. Fainting: Loss of consciousness in severe cases.
11. Heartburn: Sometimes mistaken for indigestion or acid reflux.
12. Swelling in the ankles or legs: Due to fluid retention caused by heart failure.
