title: [Coronary Angioplasty and Stenting in Patients Older Than 80 Years: Immediate and Long-Term Results].
abstract: to assess immediate and long-term results of coronary angioplasty and stenting in patients older than 80 years - a high risk group in view of the severity of concomitant pathology and extent of coronary atherosclerosis.
  
  
  
  We conducted retrospective analysis of data from 167 patients older than 80 years (mean age 81.43+/-2.14 years) subjected to percutaneous coronary intervention from 2006 to 2013 (3.2% from total number of patients). Multivessel involvement was present in 128 patients (76.6%) including 20 (12.4%) with stenosis in left main coronary artery. In 215 out of 270 stenotic lesions complicated stenoses type B2, C were detected . Number of chronic occlusions was 31 (10.3%) out of 301 treated lesions. There were 46 patients (27.5%) with diabetes, 16 (9.6%) with chronic anemia, 35 (21%) with chronic renal failure. Concomitant multifocal lesions in other arterial beds were found in 67 patients (40.1%). Radial, femoral, and combined femoral-radial accesses was used in 157 (94%), 5 (3%), and 5 (3%) patients, respectively. Results were studied with the help of automated system of digital computer angiography and intracoronary ultrasound. Long-term results were assessed with the help of questioning, control angiography, and echocardiography.
  
  
  
  Immediate angiographic and clinical success was achieved in 97 and 94% of cases, respectively. Revascularization was complete in 62.2% of cases. Hospital mortality was 0.7%. Major adverse cardiac events (MACE) were registered in 4.6 and 22.4% of patients during periods of 30 days and >24 months, respectively. Stent thrombosis was diagnosed in 3 cases (1.79%) in 6-18 months after intervention. Repeat revascularization in remote period was performed in 20 patients (12.8%), in 8 of them because of appearance of new lesion. Survival after 40 months was 91%, survival without MACE after 60 months was 74.8%. Complications related to access artery was 4.2% (1.9% in 157 transradial Interventions). According of logistic regression analysis, the following predictors of MACE in remote period were determined: initial depressed left ventricular function, diabetes mellitus, and lesion length >35 mm.
  
  
  
  Coronary angioplasty and stenting is an effective method of treatment of coronary atherosclerosis in patients older than 80 years with acceptable rate of MACE. Radial access lowers rate of access related vascular complications.
