Clinical and Angiographic Outcomes With Hyperglycemic Control Post PCI - Full Text View

Purpose

Coronary artery disease is a process that results in “hardening of the arteries”. When the arteries that supply blood and oxygen to your heart muscle become clogged or narrowed, a heart attack may result, or you may feel chest discomfort (angina) – sometimes even while resting. One approach to treating this condition is a balloon procedure known as coronary angioplasty.

The major limitation of coronary angioplasty is renarrowing of the artery (restenosis) in the first six months following the procedure requiring either repeat angioplasty or referral for bypass surgery. Patients with diabetes have always been identified as having higher rates of restenosis and poor outcomes following angioplasty, despite some important scientific advances. We think that the level of blood sugar control at the time of angioplasty and in the following months may be related to the extent of restenosis.

We expect that a reduction in blood sugar with insulin may, in turn, reduce the restenosis process and improve your long-term outcome.
