The precordial region. Pain in the chest in these patients is associated with relative coronary insufficiency due to low cardiac output, a relatively weak development of coronary collaterals on the background of hypertrophy of the wall of the right ventricle or reflex constriction of the coronary arteries due to distension of the pulmonary artery (viscero-visceral reflex), lowest saturation of blood oxygen at an advanced stage, as well as compression of the left main coronary artery dilutionin the pulmonary artery trunk. Many of them in electrocardiography revealed changes similar to ischemic. The purpose of this study was to identify signs of myocardial ischemia in patients with pulmonary arterial hypertension and evaluate the relationship of pain with the presence of ischemic changes according to 12 channel Holter ECG monitoring, and synchronized single photon emission computed tomography myocardial alone and in combination with load tests.
