CONCLUSION
In conclusion, we found that, compared to normal intraoperative TEE
metrics during diastole prior to CPB, abnormal non-systolic
echocardiographic parameters are associated with a 31% longer hospital
stay following CAB surgery in patients with normal baseline left
ventricular systolic function. In this case, diastolic dysfunction is
indicated by the presence of either E > 50 cm/sec or e’
< 10 cm/sec. The daily probability of discharge is inversely
related to the severity of performance abnormality during diastole in a
dose-dependent manner. The prolongation in hospital stay could be
accounted for neither by baseline comorbidities nor by post-op
complications. Larger studies are needed to confirm the consistency of
these results and to elucidate a modifiable cause of the prolonged
hospital stay.
