Restenosis after arterial injury caused by coronary stenting in patients with diabetes mellitus
Article Abstract:
Diabetic patients appear to have a higher risk for restenosis after coronary stenting than non-diabetic patients. Angioplasty is a surgical procedure to open a narrowed artery, and stents are positioned to maintain the open artery. Of 216 patients with coronary artery disease who underwent coronary stenting, 37 had diabetes. Restenosis, which is a recurrent narrowing of the artery, occurred in 55% of the diabetic patients compared with 20% of the non-diabetic patients. Blood vessels that were stented in diabetics and non-diabetics did not differ in diameter, length or severity of lesion or incidence of stenosis before treatment. The change in minimum diameter of vessels stented before and after the operation did not differ significantly between diabetics and non-diabetics. However at follow-up, the minimum diameter of stented blood vessels in patients who were diabetic was significantly smaller than that in patients who were not diabetic. Restenosis in diabetics may be due to a tendency toward late loss of minimum diameter.

Primary Angioplasty Compared with Thrombolysis: New Issues in the Era of Glycoprotein IIb/IIIa Inhibition and Intracoronary Stenting
Article Abstract:
A review of different methods for opening clogged coronary arteries is presented. Balloon angioplasty is the most common way of doing this. A catheter with a balloon is inserted into the arteries, the balloon is inflated and presses against the walls of the arteries, flattening any plaque. Thrombolytic drugs can break up blood clots that block arteries and cause most heart attacks. New techniques include small cylinders called stents, drugs that block platelet aggregation and newer thrombolytic drugs.

Recent coronary stenting increases the risk for postoperative cardiac complications
Article Abstract:
A larger group of patients whose coronary stent preceded noncardiac surgery were studied. The association between recent coronary stenting and an increased risk for postoperative cardiac complications and death were confirmed.
