[Changes in hemodynamics and oxygen demand in patients with ischemic heart disease during graded psychoemotional...

One hundred and forty five patients were subjected to graded psychoemotional stress, their oxygen demand being simultaneously analysed. Ischemia was found to develop the more frequently, the more severe functional class a patient has with a negative stress, the patients had higher oxygen consumption, larger cardiac output, lower total peripheral resistance. Myocardial ischemia occurred with inadequately increased oxygen consumption during the test, diminished stroke volume and enhanced total peripheral resistance.
