Coronary Artery Disease

Risk factors such as age, diabetes, hypertension, smoking, high blood cholesterol levels and family history can cause lipid (fatty) materials to clog these small diameter coronary arteries and form what are known as plaques (little humps of fatty material with some calcium deposits making them hard) on the inside lumen the artery. As the size of the plaque increases, the arteries start to narrow or stenose.

When one or more of these arteries get blocked the blood supply is reduced to the area of the heart muscle resulting in lack of nutrients and oxygen supply especially during exercise or exertion. This is often called "Coronary artery disease" (CAD) or "Atherosclerotic Heart disease".

Most people start experiencing chest pains or other symptoms like fatigue or shortness of breath when the block is over 50%. As the block gets narrower, symptoms increase either in intensity or frequency or both.

Heart attack or Myocardial Infarction occurs when the artery is completely occluded and the muscles die.

ECG, Treadmill, Echocardiogram will be done to diagnose CAD. Angiogram is done to show the accurate percentage of blocks in each artery.

my child had a blockage in his volve by birth. his balooning has been done since he was at the age of 22 days. we are regularly going to dr. for periodically check up as and when suggested. My son is now 11 years old he has no problem except swetting as and when he runs very fast while playing or otherwise. He is living is having good health comparing to a normal child. I just want to clear my doube that in the long run can we have any problem relating to volve in future or he will be alright for ever.

I had CABG 13 years ago (at age 69) and it resulted in a stroke that left me with hemiplegia. Now, my angina is returning, but I'm treating it with Seanol - which so far (2 months)has been successful. Rowland
