Echocardiographic parameters of left ventricular non-systolic function predict length of stay following coronary artery bypass graft -- a prospective observational study

Study design: Observational Study
Abstract: Background: Abnormal left ventricular (LV) echocardiographic parameters during non-systolic phase, with or without a diagnosis of heart failure, is a common finding that can be easily diagnosed by intra-operative transesophageal echocardiography (TEE). However, its association with duration of hospital stay after coronary artery bypass (CAB) is unknown. Objective: To determine if Abnormal left ventricular (LV) echocardiographic parameters during non-systolic phase is associated with length of hospital stay after coronary artery bypass surgery (CAB). Method: Prospective observational study at a single tertiary academic medical center Result: Median time to hospital discharge was significantly longer for subjects with abnormal left ventricular (LV) echocardiographic parameters during non-systolic phase (9.1/IQR 6.6-13.5 days) than those with normal LV non-systolic function (6.5/IAR 5.3-9.7days) (P< 0.001). The probability of hospital discharge was 34% lower (HR 0.66/95% CI 0.47-0.93) for subjects with abnormal LV function even during non-systole despite a normal LV systolic function, independent of potential confounders, including a baseline diagnosis of heart failure Conclusions and Relevance: In patients with normal systolic function undergoing CAB, non-systolic LV dysfunction is associated with prolonged duration of postoperative hospital stay. This association cannot be explained by baseline comorbidities or common post-operative complications.
