The use of artificial electric ventricular fibrillation (AEVF) at the main stage of coronary artery bypass grafting (CABG) in conditions of artificial blood circulation (ABC) is considered in the article. The aim of research is to define an efficiency of AEVF as a method of the local cardioprotection at CABG.
Methods. Research included 64 patients 58-72 years old who underwent CABG with ABC.
There were analyzed the main indicators of hemodynamics and myocardial contractility, the rate of the use of adrenomimetics in postperfusion period and also the level of cardiospecific enzymes in early postsurgical period.
Results. There was established that at the given type of local cardioprotection for the end of the first postsurgical day the index of stroke work of the left ventricle increased by 38,4±1,2 %, stroke index by 21,2±1,34 %, ejection fraction increased by 18,1±0,87 %, cardiac index – by 15,6±1,23 %, relative to initial values.
Indicators of myocardial fraction of creatine phosphokinase and Troponin 1 corresponded with uncomplicated course of postsurgical period for cardiac surgery.
Conclusion. The use of AEVF is an effective method of local cardioprotection at the main stage of CABG in conditions of ABC it has no negative effect on contractility of myocardium and on the level of cardiospecific enzymes.
