does any know what rca occluscar means in a heart test?

Question

the results were rca occluscar chronic

Answer 1

RCA means right coronary artery, which is one of the three main arteries which gives blood supply to the heart. The fact that it is occluded, means that the heart is not getting enough blood supply in certain areas, particularly when it is beating a little faster, for example if you walk up a hill or a flight of stairs. When the heart muscle doesn't get enough blood, it doesn't get enough oxygen, and it becomes "hypoxic" which causes pain, commonly refered to as angina.

Answer 2

It sounds like you have had an angiogram The RCA is the right coronary artery. It is one of the three main blood vessels that suply the heart with blood. The amount of the heart that this vessel supplies with blood varies greatly between people In some it supplies predominantly the right side of the heart ( this side is the weaker side of the heart and requires less oxygen than the left) In others the RCA can supply a significant part of the left side of the heart ( this is the strong side that pumps the blood around the body . In thses latter people the RCA is described as being "dominant". The fact that the block ( occlusion) means that it has not just happened as part of a recent heart attack.

It may have happened suddenly in the past as a result of a heart attack or it could have furred up slowly over a period of time. This can be an important distinction.

If the block occured suddenly some time ago then a lot of the heart muscle that this blood vessel supplied may have died and been replaced by scar tissue . In these cases opnening up the blockage or by-passing it may have little or no benefit

If the furring up has occured slowly then the heart may have had chance to adapt to the ever decreasing blood flow and developed its own natural form of limited by-pass graft thereby minimised the amount of damage to the heart muscle. In such instances the blood flow to the muscle maybe limited but enough to keep it alive.However when the heart is stressed the muscle may then get insufficient blood thereby causing angina ( heart pain) In these cases procedures to deal with the blockage can be helpful


Obviously I do not know the specifics of your case and there are many imponderables but i hope that this has been helpful

Answer 3

In addition to the comments made by "badgerwithagun", CHRONIC (as you have stated) refers to the occlusion as having been present for some time, as in, a relatively long time. Without arteriography (a heart cath), your unspecified test reflects the right coronary artery involvement probably based on a diminished to total lack of contractility/function of the heart muscle on the inferior (or diaphragmatic) surface - the underside of the heart that rests on the diaphragm which is typically supplied with blood by the RCA.


Please understand, these comments are somewhat speculative, not knowing the specific 'heart test' you had performed.
False positives (a false indication of trouble or a problem) from stress/nuclear tests have been known to occur, such as in a large breasted woman or one who has a high diaphragm that overlies the heart. In either case, the nuclear imaging portion of the stress test (if that is the type of heart test you had conducted) would not reveal a true picture of blood flow because of the interference caused by the obstructing mass.

Without more information, this is the best we can do for you.

Answer 4

RCA means right coronary artery, its the artery that supplies the muscles of the right side of the body. You must mean occlusion of the RCA. did you undergo a coronary angiogram because that's the only direct and definitive ways of knowing that the RCA is blocked or did you only had an ECG or 2d echo?

Answer 5

The RCA is the right coronary artery and the occlusion refers to the amount of damage done to it. I would ask your doctor what your results were as thats one thing I cannot know without seeing for myself xx
