title: [Endovascular treatment for chronic coronary occlusions in patients with coronary heart disease].
abstract: OBJECTIVE
  To analyze the angiographic results of endovascular treatment for chronic coronary occlusions in patients with coronary heart disease.
  
  
  METHODS
  In 2009 to 2013 attempted endovascu-ar recanalization of chronic coronary occlusions in 854 patients with coronary heart disease. The patients' age ranged from3 6 to 68 years (mean 52 years). The estimated du-ation of occlusion was m1 onth to more than 3 years. There were 193 (22.6%) females and 661 (77.4%) males. 462 (54.1%) patients had a history of myocardial infarction. 738 (86.4%) and 116 (13.6%) patients had true (TIMI grade 0) and functional (TIMI grade i1 occlusions, respectively. Multi- and univascular lesions were found in 683 (79.9%) and 171 (20.1%) patients, respectively. Silent occlusions with preserved myocardial contractility were identified in 165 (19.3%) patients. RRESULTS:Blood flow could be successfully restored in 616 (72.1%) patients. Recanalization of chronic coronary occlusion failed in 238 (27.9%) patients. CCONCLUSION:Recanalization of chronic coronary occlusions is a highly effective and relatively safe technique. The efficiency of the procedure largely depends on the duration of occlusion, its X-ray morphological characteristics, and the experience of a physician.
