Summary: | We sought to compare coronary stent implantation with balloon angioplasty (BA), in a diabetic population, in terms of the six-month angiographic outcome and four-year clinical events.
Diabetic patients have a poor angiographic and clinical outcome after standard coronary BA. To date, it is still unclear whether stent implantation may improve this outcome.
We investigated this issue by individual matching of 314 diabetic patients treated with either coronary stenting or standard BA. These two groups were derived from a population of consecutive diabetic patients (1993 to 1996). Matching criteria were gender, anti-diabetic regimen, stenosis location, reference diameter, and minimal luminal diameter (±0.4 mm). One lesion per patient was considered for matching.
Baseline characteristics were similar between the two groups of 157 patients. At six months, the rates of restenosis (27% vs. 62%; p < 0.0001) and occlusion (4% vs. 13%; p < 0.005) were lower in the stent group than in the BA group. This was associated with a significant decrease in ejection fraction at six months in the BA group (p = 0.02) while, during the same period, no change was observed in the stent group (p = NS). Subgroup analysis demonstrated that angiographic benefit was consistent among the subgroups. At four years, the combined clinical end point of cardiac death and non-fatal myocardial infarction was lower in the stent group (14.8% vs. 26.0%; p = 0.02), as was the need for repeat revascularization (35.4% vs. 52.1%; p = 0.001).
In a population of diabetic patients, coronary stent implantation was associated with a highly beneficial effect on the six-month angiographic outcome and four-year clinical events compared with standard BA. |
