title: [Noninvasive assessment of myocardial functional reserves in young women with nonspecific aortoarteritis and aortic arch syndrome].
abstract: OBJECTIVE
  To study functional myocardial reserve in patients with nonspecific aortic arteritis (NAA) and aortic arch syndrome (AAS).
  
  
  METHODS
  Myocardial functional reserve was studied in 42 patients with NAA using ECG, spiroveloergometry, section and doppler echocardiography, radionuclide ventriculography. Healthy nonsportswomen served control.
  
  
  RESULTS
  ECG revealed left ventricular hypertrophy in most of the patients, spiroveloergometry showed low exercise tolerance in many NAA patients. Echocardiography detected differences in patients vs controls by diastolic thickness of the interventricular septum, left ventricular myocardial mass and aortic diameter. As shown by radionuclide ventriculography, 75% of NAA patients with predominant affection of the aortic arch branches had disturbed ventricular function.
  
  
  CONCLUSIONS
  84% of NAA patients with AAS at veloergometry exhibited signs of transitory myocardial ischemia. Hemodynamic changes at exercise demonstrated low coronary reserve. Silent myocardial ischemia is typical for NAA patients.
