[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.
