RESULTS The total mortality was 42%, with 36.4% in coronary heart disease patients and 64% in non-coronary heart disease patients (P.05). In patients using IABP preoperatively, the mortality was much lower than that in patients using IABP during or postoperatively (0%, 40%, 50% respectively, P.05). After using IABP, homodynamic data improved and dose of cardiovascular drugs decreased significantly.
