FIELD: medicine.
SUBSTANCE: invention relates to medicine, cardiology and can be used in diagnostics and treatment of CHD with unchanged/slightly changed coronary arteries (Cardiac syndrome X, CSX). Single-photon emission computed tomography (SPECT) of myocardium with introduction of radiopharmaceutical is preliminarily performed to patient at rest state with further introduction of 1% ATP solution at rate 0.10-0.20 mg/kg for 1-5 minutes. SPECT of myocardium is repeated, and conclusion about presence of myocardium ischemia is made after comparison of its myocardium perfusion parameters with parameters, measured in rest state. Introduction of radiopharmaceutical for repeated SPECT is performed after finishing introduction of ATP, with repeated SPECT being carried out not sooner than 1 hour after ATP introduction.
EFFECT: method ensures non-invasive, highly sensitive provocation of myocardium ischemia in patients with CSX with verification of impaired coronary reserve.
