Coronary Stenosis: What you should know


Posted on 23rd November 2010 by admin in Uncategorized

Coronary stenosis is the narrowing of the blood vessels of the heart.  There are three common types of coronary stenosis.  Aortic stenosis, triple vessel coronary heart disease and coronary artery stenosis are types of coronary stenosis.  While learning about the allied health fields, the heart is one good way to start.

Aortic stenosis is the narrowing of the aorta.  This narrowing can occur in the area where the aorta leaves the left ventricle or can be caused from scarring or inflammation of the aortic valve.  Stenosis of the aortic isthmus occurs when the region of the aortic arch narrows.  This can result in inadequate blood flow to the lower half of the body.  Aortic stenosis is sometimes discovered by chance when high blood pressure is under investigation.  An ECG can show the strain that is being placed on the left ventricle.  This can also be seen on X-ray as an abnormally enlarged section of the heart.  Reduced blood supply to the brain, dizziness, fainting, heart palpitations, breathlessness and cardiac rhythm disturbances are signs of arotic stenosis.

Triple vessel coronary heart disease is caused from atherosclerosis or calcification of the three main branches of the coronary arteries.  Without treatment this disease is fatal.  The only option for treatment is surgery which will require that the stenosed vessels be bypassed or replaced.  If it is impossible to do either, the only remaining option is a heart transplant.

Coronary artery stenosis is the narrowing of the coronary arteries.  Symptoms usually only appear when the coronary vessel is narrowed by at least 70%.  Symptoms, such as stress related pain behind the sternum are most common.  If untreated, it can result in a myocardial infarction.
