What would happen if the circumflex artery get blocked?
Background. Occlusion of the circumflex artery (Cx) often does not present signs in the ECG. It can lead to delayed angiography during ST-elevation myocardial infarction (STEMI).
What is the function of the left marginal artery?
The left main coronary artery supplies blood to the left side of the heart muscle (the left ventricle and left atrium).
What do you do if your artery is blocked?
This could involve inserting a tube into the artery to remove the plaque while leaving behind a stent to support the artery walls and increase blood flow. With severe blockages, doctors may perform surgery called a heart bypass to make sure the blood can get around the obstructed artery.
What happens to your heart when your artery is blocked?
Sometimes, when arteries become completely blocked, a new blood supply develops around the blockage. This new blood supply, called collaterals, won’t deliver as much blood to your heart. This can lead to those same symptoms of chest pain and shortness of breath.
What happens when the left anterior descending artery is blocked?
The left main coronary artery divides into left anterior descending artery (LAD) and left circumflex artery. The function of these arteries is to supply oxygenated blood to anterior (front) portion of the heart. When the left anterior descending artery is blocked, the blood supply to the heart muscle is reduced causing many symptoms.
Where does the right marginal artery begin and end?
The right marginal artery originates from the right coronary artery at the inferior (acute) margin of the heart, as one of its largest branches. It courses along the inferior margin towards the apex of the heart, being followed by the right marginal vein.
What are the symptoms of a blocked circumflex artery?
When symptoms remain present, each patient may experience it in a different way. Common symptoms associated with the blocked circumflex artery problem are: Huge pressure, tightness, heaviness or pain in the patient’s chest, particularly, at the back portion of his breastbone. Fatigue and weakness are also symptoms of blocked circumflex artery.
