THE EFFECTS OF INTRAAORTIC BALLOON PUMPING COMBINED WITH CORONARY SINUS INTERVENTIONS ON FAILING HEARTS - A MODEL STUDY

Cardiac energy balance is an important factor in evaluating cardiac fu nction. In this work, the effects of different assist modalities and t heir combinations on cardiac energy balance and global cardiac functio n have been investigated. The simulation results indicate that coronar y sinus interventions (CSIs) can provide myocardium with more energy t han IABP when coronary arterial stenosis is serious. However, IABP can decrease myocardial energy consumption and enhance cardiac output, wh ich cannot be done by CSIs, under the condition of impaired myocardial contractility. Therefore, we conclude that the combination of IABP an d CSIs is the best way of assisting failing circulation. Copyright (C) 1996 Elsevier Science Ltd.
