[Efficiency of endovascular re-interventions for evolving restenosis of different types of stents].
The paper compares the results of different treatment options (balloon angioplasty and restenting) for in-stent restenosis in case of evolving restenosis of drug- and nondrug eluting stents. The investigation enrolled 496 coronary heart disease patients with clinical presentation of angina pectoris and/or signs of myocardial ischemia, as well as hemodynamic restenosis of a previously implanted stent. Of them, 216 and 280 patients had restenosis of previously implanted drug- and nondrug-eluting stents, respectively. In the patients with non-drug-eluting stent restenosis, recurrent angina pectoris and the frequency of repeated restenosis were significantly more frequently observed after balloon dilatation than after drug-eluting stent implantation (28.4 and 10.2%; p < 0.05; 19.9 and 8.7%; p < 0.05). In those with drug-eluting stent restenosis, recurrent angina pectoris and the frequency of repeated restenosis did not differ significantly between balloon dilatation of restenosis and implantation of a second drug-eluting stent.
