Influence of vessel size and diabetes on angiographic long-term variables after coronary stent implantation.

In order to compare the rate of restenosis in diabetic and non-diabetic pat ients in relation to vessel size, we studied 368 patients,vith 421 lesions following coronary stent implantation, Clinical and long-term angiographic variables were compared between diabetic and non-diabetic patients, There w ere 209 non-diabetic and 61 diabetic patients out of 270 patients with 293 lesions who had a complete angiographic follow-up at 6 months, At follow-up , diabetic patients showed a significant higher diameter stenosis and a hig her late lumen loss in the stenotic vessel segment (p = 0.006, p = 0.0141, The rate of restenosis was 35% in diabetic lesions as compared to 20% in no n-diabetic lesions (p = 0.014), In vessels <3.0 mm, the rate of in-stent-re stenosis was as high as 44.2% in the diabetic patient population.
