“…The factors independently associated with restenosis in our study are similar to those already described, such as reference diameter, residual stenosis after the procedure, and lesion extension [10][11][12][25][26][27][28] . We have also demonstrated that higher balloon/artery ratios and narrower vessels are associated with dissections; this finding should direct technicians to optimize the stent size, especially in patients with smaller vessels.…”

“…A combination of patient factors, such as diabetes, lesion variables including length and vessel size, and type of revascularization device, all influence the likelihood of restenosis. [1][2][3][4] With the evolution of core laboratories, such as Cardialysis in Rotterdam, large databases of clinical and angiographic data provide a unique opportunity to identify factors that may influence the restenotic process.…”

Clinical and Angiographic Factors Associated With Asymptomatic Restenosis After Percutaneous Coronary Intervention

et al. 2001

Background Angiographic restenosis after percutaneous coronary interventional procedures is more common than recurrent angina. Clinical and angiographic factors associated with asymptomatic versus symptomatic restenosis after percutaneous coronary intervention were compared. Methods and Results All patients with angiographic restenosis from the BENESTENT I, BENESTENT II pilot, BENESTENT II, MUSIC, WEST 1, DUET, FINESS 2, FLARE, SOPHOS, and ROSE studies were analyzed. Multivariate analysis evaluated 46 clinical and angiographic variables, comparing those with and without angina. The 10 studies recruited 2690 patients who underwent percutaneous revascularization and 6-month follow-up angiography (86% of those eligible). Restenosis (≥50% diameter stenosis) occurred in 607 patients and was clinically silent in 335 (55%). Male sex ( P =0.008), absence of antianginal therapy with nitrates ( P =0.0002) and calcium channel blockers ( P =0.02) at 6 months, greater reference diameter after the procedure ( P =0.04), greater reference diameter at follow-up ( P =0.004), and lesser lesion severity (percent stenosis) at 6 months ( P =0.0004) were univariate predictors of asymptomatic restenosis. By multivariate analysis, only male sex ( P =0.04), greater reference diameter at follow-up ( P =0.002), and lesser lesion severity at 6 months ( P =0.0001) were associated with restenosis without angina. Conclusions Approximately half of patients with angiographic restenosis have no symptoms. The only multivariate predictors of silent restenosis at 6 months were male sex, greater reference diameter at follow-up, and lesser lesion severity on follow-up angiography.

“…This is further supported by the moderate restenosis rate after balloon dilatation alone (23.9%), and also for all lesions treated in this interventional series (18.0%). Restenosis after short stent implantation was influenced by the same variables as for other investigations, namely vessel and stent dimensions, and final luminal diameter, but not by lesion length [6, 19]. Contrary to other analyses using longer stent lengths, diabetes did not appear to influence restenosis in the short stent group [20, 21].…”

“…Furthermore, much longer stents were used than necessary to cover the target lesion in most lesions as reported in an analysis of several interventional trials using BMS [5]. Since BMS less than 10 mm in length exhibit restenosis rates between 3 and 11% in nondiabetic and 5–18% in diabetic patients, depending on the vessel diameter [6, 7], shortening the stent length might reduce the restenosis rate in BMS. We therefore conducted a prospective study to investigate in which proportion of vessels the shortest available stent could be used routinely and to determine the long-term results.…”

Short Stent Implantation for Routine Use Is Feasible in a High Proportion of Coronary Interventions and Yields a Low Restenosis Rate

et al. 2005

Stent length predicts restenosis. The feasibility of using a short stent (<10 mm) routinely was investigated in 331 consecutive patients treated for 424 coronary artery lesions. A single short stent provided suitable coverage and achieved a residual stenosis <30%, with or without predilatation, in 252/424 lesions (59.4%). Longer stents were implanted in 58/424 lesions (13.7%), while only percutaneous transluminal coronary angioplasty was performed in 114/242 lesions (26.9%). Angiographic success and procedural success were achieved in 250/252 lesions (99.2%). Restenosis occurred in 36/231 lesions (15.6%) after short stenting, in 10/53 lesions (18.9%) after long stents, in 21/88 lesions (23.9%) after percutaneous transluminal coronary angioplasty, and in 67/372 lesions (18.0%) controlled angiographically. Only small vessel diameter predicted restenosis after short stenting. Thus, a single short stent implanted directly or after predilatation is sufficient to achieve an acceptable angiographic result in more than in nearly 60% of all treated lesions. Short stenting results in a low restenosis rate.
