title: [Diagnosis of coronary atherosclerosis using echocardiography with bicycle ergometry exercise].
abstract: OBJECTIVE
  To determine sensitivity and specificity of stress echocardiography (SEC) in diagnosis of stenosing atherosclerosis of coronary arteries (CA), especially in patients recovered from Q-myocardial infarction.
  
  
  METHODS
  The above sensitivity and specificity were studied in 75 patients (70 males and 5 females; mean age 53.7 +/- 7 years) with coronary atherosclerosis (CS).
  
  
  RESULTS
  The sensitivity of impaired local contractility index (ILCI) in univessel lesion was 77.8%, in multivessel lesion--90.4%, specificity--85.7%. Sensitivity of other parameters studied was for development of an anginal episode 65.4%, increment of ejection fraction under 5%--63.9%, increased end systolic volume--61.1%, depression of ST segment--48.1%, increased end diastolic volume 38.9%. A total of 3 parameters had 100% sensitivity: impossible a > 5% rise of EF in response to exercise, an increase of end systolic and diastolic volumes, anginal attack (85.7%), ST depression (78.6%).
  
  
  CONCLUSIONS
  Hemodynamic parameters must be assessed in the course of SECG for objectivization of the result and improvement of its specificity.
