Why the study?
Does intraaortic balloon counterpulsation improve left ventricular systolic function selectively in augmented cardiac beats by acutely decreasing left ventricular afterload in anesthetized cardiac surgical patients?
Population
20 anesthetized cardiac surgical patients during intraaortic balloon counterpulsation (IABP) support
Comparison
IABP-augmented cardiac beats vs Nonaugmented cardiac beats
Design
Other
Follow-up
Immediate (beat-to-beat)

May support IABP afterload reduction in augmented beats during cardiac surgery; hypothesis-generating, needs prospective validation.
Does intraaortic balloon counterpulsation improve left ventricular systolic function selectively in augmented cardiac beats by acutely decreasing left ventricular afterload in anesthetized cardiac surgical patients?
Intraaortic balloon counterpulsation instantaneously improves left ventricular systolic function by reducing afterload on a beat-to-beat basis in cardiac surgical patients.
