This study was undertaken to analyze change in stenosis caliber up to six months after PTCA with respect to regression or progression as well as to detect factors which possibly influencing the restenosis rate. A computer assisted system with high accuracy was used for two-dimensional quantitation of stenosis. A linear multivariate analysis was applied to quantitative and qualitative angiographic data as well as to clinical findings obtained before, immediately after and six months post-PTCA in 95 consecutive patients in whom 101 stenoses were dilatated. All patients were on a standard medical regimen of aspirin or coumadin and nifedipine. After six months, 56 patients showed a change in minimal stenosis area (mSA) of less than 1 mm2 (no progression), 33 patients showed a decrease in mSA of greater than 1 mm2 which rendered the stenosis with greater than 70% luminal reduction, and 12 patients showed a decrease in mSA of greater than 1 mm2 which did not, however, result in high-grade luminal narrowing. With regard to factors capable of affecting restenosis rate, there was no relationship between extent of dilatation achieved, local dissection, stenosis configuration or localization, calcification, patient age, sex, duration of symptoms, overweight, cholesterol, triglycerides, HDL, LDL, smoking, hypertension or diabetes. However, a relationship was found between the discontinuation of aspirin or coumadin as a result of GI side effects or bleeding (2% no progression; 20% progression). Thus, antiplatelet therapy appears to be important with respect to long-term results after PTCA. |
