Treatment

The results of the PET/CT scan will help the physician determine the best course of treatment and could include medical treatment with drugs such as cholesterol lowering medications, coronary interventions such as angioplasty or coronary stent implantation, or coronary artery bypass surgery.

Angioplasty or coronary stent implantation is the technique of mechanically widening a narrowed or obstructed blood vessel. Coronary stents containing tightly folded balloons are passed into the narrowed locations and then inflated to a fixed size using water pressure. The balloon is then removed leaving the stent in place, pressed into the newly opened artery wall.

Coronary artery bypass surgery is a type of heart surgery. It's sometimes called CABG ("cabbage"). The surgery reroutes, or "bypasses," blood around clogged arteries to improve blood flow and oxygen to the heart.

Normal during both exercise and rest portion of the test, then blood flow through the coronary arteries is normal.

Normal during rest but is reduced in part of the heart during exercise, then part of the heart is not getting enough blood when it is working harder than normal, which may be due to a blockage.

Reduced in a part of the heart during both exercise and rest, then the blood flow to that part of the heart is restricted at all times.

The results of the PET/CT scan will help the physician determine the best course of treatment.
