The early results of endovascular treatment of chronic coronary occlusion were studied. Immediate success rates were 67%. The factors that promote successful endovascular treatment in patients with this condition were as follows: less than 2-month disease duration, well-developed intersystemic collaterals, no "bridge" collaterals. Successful recanalization for chronic coronary occlusion improves the quality of life and bicycle ergometer test finding in patients, which reduces their needs of nitrates and beta-blockers. Coronary occlusion stenting yields better immediate angiographic results than does balloon angioplasty: residual stenosis and the minimum diameter of stenosis after stenting were 13.61 +/- 6.3% and 2.69 +/- 0.4 mm, respectively; those after balloon angioplasty were 23.1 +/- 8.1% and 2.31 +/- 0.37 mm, respectively.
