Study Population

Stable patients with dyspnea and established coronary artery disease.

You may qualify if:

  • Stable patients with shortness of breath and established diagnosis of coronary artery disease (at least 1 of the following signs):
  • history of myocardial infarction;
  • typical angina without suspected other cause of pain;
  • myocardial ischemia documented by ECG changes during symptoms and/or by results of the stress test;
  • coronary artery stenosis \>50% according to coronary angiography.
  • Signed informed consent.

You may not qualify if:

  • Acute coronary syndrome (myocardial infarction, unstable angina) in the previous month.
  • Hospitalization with decompensation of CHF in the previous 6 months (including CHF decompensation as the main reason for current hospitalization).
  • Diseases with an unfavourable prognosis (terminal CKD, CHF NYHA IV, a lung disease with severe respiratory failure).
  • Contraindications to bicycle stress echocardiography.
  • Atrial Fibrillation at the time of hospitalization, when the decision not to restore the sinus rhythm.
  • Mental illnesses and disorders, dementia, drug or alcohol dependence.
  • Known oncological diseases.
