Effect of intra-aortic ballon counterpulsation on central hemodynamics and oxygen-transport function of the circulatory system when performing myocardial revascularization in CHD patients with a low

78 CHD patients operated under extracorporeal circulation over a period from 2003 to 2006 were studied to analyze the parameters of central hemodynamics and oxygen-transport function of the circulatory system, as well as their clinical state. The study results demonstrate that using intra-aortic balloon counterpulsation in CHD patients, when performing myocardial revascularization, contributes to a significant increase in cardiac index and oxygen-consumption index. The increase in cardiac index, in turn, improves total metabolism of tissues as evidenced by an oxygen consumption index increasing directly with the cardiac index.
