[Pathogenesis of myocardial ischemia in information stress in patients with ischemic heart disease].

A study of 48 coronary patients demonstrated that coronary as well as systemic vasospasm resulting in a drop of propulsive left-ventricular capacity are the principal pathogenic factors leading to myocardial ischemia under emotional stress. In patients with coronary arterial stenosis, increased myocardial oxygen want due to increased stroke and minute volumes contributes significantly to ischemic response to stress. The use of corinfar is advisable to prevent the development of emotion-induced vasospasm. The use of information stress with ECG and central hemodynamic monitoring permits noninvasive diagnosis of coronary spasm.
