[Phenomenon of preoperative stress in patients with ischemic heart disease. Assessment of its clinical and prognostic significance].

Aim: To assess preoperative stress in patients with ischemic heart disease (IHD) and its influence on the course of early intraoperative period.

Materials And Methods: 79 patients scheduled for aortocoronary bypass operation were studied to assess the phenomenon of preoperative psychoemotional stress (clinical characteristics, personal anxiety, humoral and vegetative regulation.

Results: 24 hours before operation IHD patients became anxious, coronary insufficiency and arrhythmia aggravated as shown by Holter ECG monitoring. Initial insufficiency of the antioxidant system, disturbances of the platelet-vascular hemostasis, hyperlipidemia and dyslipoproteinemia enhanced. Preoperative changes due to stress reaction affected the course of early intraoperative period.

Conclusion: It is necessary to apply individual schemes of stress-limiting preoperative preparation in IHD patients.
