Medically refractory unstable angina pectoris. II. Hemodynamic and angiographic effects of intraaortic balloon counterpulsation. 1979

J M Aroesty, and R M Weintraub, and S Paulin, and G P O'Grady

Of 60 patients receiving intraaortic balloon counterpulsation for angina refractory to maximal medical therapy, a subgroup of 10 patients underwent left ventricular angiography both with and without counterpulsation. Severe stenosis of the left anterior descending coronary artery was present in all 10 patients. Counterpulsation resulted in a significant decrease in systolic and end-diastolic left ventricular pressures and no increase in cardiac index. Left ventricular diastolic and systolic volume, ejection fraction and regional contraction patterns, often abnormal, were unchanged. However, mean normalized systolic ejection rate was improved by the addition of counterpulsation. It is concluded that intraaortic balloon counterpulsation has relatively little effect on the left ventricular volume of patients with medically refractory angina pectoris. The symptomatic improvement that takes place seems to occur mainly through the effect of counterpulsation on preload and afterload.

UI	MeSH Term	Description	Entries
D007423	Intra-Aortic Balloon Pumping	Counterpulsation in which a pumping unit synchronized with the patient's electrocardiogram rapidly fills a balloon in the aorta with helium or carbon dioxide in early diastole and evacuates the balloon at the onset of systole. As the balloon inflates, it raises aortic diastolic pressure, and as it deflates, it lowers aortic systolic pressure. The result is a decrease in left ventricular work and increased myocardial and peripheral perfusion.
