title: Current status of intra-aortic balloon counterpulsation in critical care cardiology.
abstract: Retrospective analysis revealed that intra-aortic balloon counterpulsation was attempted in 321 patients at our institute from August 1, 1974, to July 1, 1982. The intra-aortic balloon pump (IABP) was successfully inserted in 298 cases (93%). Indications for an IABP included: cardiogenic shock (84 cases), preoperative hemodynamic coverage (15 cases), low-output syndrome (73 cases), pre- and postinfarction angina (75 cases), intractable congestive heart failure (12 cases), refractory ventricular arrhythmia (9 cases), percutaneous transluminal coronary angioplasty (14 cases), cardiac arrest (7 cases), and a miscellaneous group (9 cases). The overall major complication rate was 9%. The data from this experience support aggressive management of cardiogenic shock, i.e., early balloon insertion, angiography, and cardiac surgery, which significantly increases the survival rate (83%) over medical therapy combined with balloon counterpulsation alone. The IABP was also extremely effective in managing other high-risk categories when combined with some form of definitive mechanical correction, e.g., coronary revascularization, valve replacement, or percutaneous transluminal coronary angioplasty. Left ventricular (LV) function was a significant indicator of long-term survival in our series. Patients with normal or moderately impaired LV function had higher survival rates (95% and 82%, respectively) than patients with poor LV function (42%).
