The long term effect of intra-aortic balloon counterpulsation on left ventricular performance.

A patient who had had two coronary artery bypass grafts and an aneurysmectomy required intra-aortic balloon pump (IABP) assistance to allow discontinuation of cardiopulmonary bypass (CPBP). An indwelling electromagnetic flow probe on the ascending aorta was used to monitor IABP over the following 8 days of assistance. Stroke volume (SV), Cardiac output (CO), stroke work (SW), and ventricular afterload (VA) were measured directly. Recovery was indicated as the discrepancy between CO and SV on and off IABP decreased. VA depended upon the degree of augmentation. SW bore an incostant relationship to IABP.

[Use of intra-aortic balloon counterpulsation in treating acute heart failure in heart surgery patients].

Intra-aortal balloon contrapulsation (IABC) was used as part of combined treatment for acute cardiac failure following cardiac surgery in 17 patients. The monitoring of cardiac output and pressure inside the heart's cavities (using the thermodilution method) showed IABC to produce an obvious hemodynamic effect. Six patients survived. Acute myocardial infarction as a cause of cardiac failure considerably aggravated the outcome. The final result of treatment was not satisfactory in such patients. It is stressed that IABC should be started as early as possible (not later than 2-3 hours after signs of acute heart failure first appear).

[Causes of death in myocardial infarct complicated by cardiogenic shock during the use of intra-aortic balloon counterpulsation in their treatment].

On the basis of the analysis of medical histories, clinical pattern of the disease, hemodynamic data and pathologic anatomical findings, conclusions are made as to causes of death in patients with acute myocardial infarction aggravated by cardiogenic shock (with intra-aortal balloon contrapulsation as part of combined treatment). They are mostly related to the duration of coronary disease in the different group of patients. The best results were obtained in cases where coronary disease had lasted for about five years, and the shock developed around 15 hours after the onset of myocardial infarction.
