coronary artery

Either of two arteries that originate in the aorta and supply blood to the muscular tissue of the heart.

coronary artery

one of a pair of arteries that branch from the aorta, including the left and the right coronary arteries. Because these vessels and their branches supply the heart, any dysfunction or disease that affects them can cause serious, sometimes fatal complications. Coronary arterial anastomoses occur throughout the heart and are especially numerous within the interventricular and interatrial septa, at the apex of the heart, at the crux, over the anterior surface of the right ventricle, and between the sinus-node artery and the other atrial arteries. These anastomoses are more numerous and larger in the epicardium than in the endocardium, and they provide important collateral circulation in the recovery of patients who suffer coronary occlusions. The branches of the coronary arteries are affected by many different disorders, such as embolic, neoplastic, inflammatory, and noninflammatory diseases.

Patient discussion about coronary artery

Q. my mother have stem replacement for a coronary artery oclusion is already 2 years she physically deteriorating since surgery why???? please help she does not have energy

A. I agree with Dagmar. It can be most likely caused by another occlusion or re-occlusion inside the heart blood vessels. Since that is a life-threatening case, I strongly suggest you to bring your mother into a hospital (for complete check up), or just call your cardiologist to have first treatment.

Meanwhile, that will be better if you have emergency oxygen (just in case you'll need it) with you.
