Abstract:
Objective: To analyze and to predict the 1 year re-admission risk in patients of chronic heart failure with reduced left ventricular ejection fraction (HFrEF) by echocardiography.
Methods: A total of 313 HFrEF patients in our hospital community from 2007-01 to 2008-12 were studied. The patients were followed-up for (6-7) years and the end point was 1 year re-admission. All patients received routine echocardiography and the parameters included left ventricular ejection fraction of (LVEF), left ventricular diameter (LVd), pulmonary artery systolic pressure (PASP), mitral regurgitation (MR), tricuspid regurgitation (TR) and pericardial effusion. Based on the above 6 parameters, the risk factors for 1 year re-admission were analyzed.
Results: Univariate analysis indicated that MR (HR=1.437, 95%CI 1.190-1.737, P=0.000), TR (HR=1.288, 95%CI 1.056-1.572, P=0.013) and pericardial effusion (HR=1.560, 95%CI 1.050-2.318, P=0.028) had better predictive value for 1 year re-admission. Multivariate analysis presented that MR (HR=1.404, 95%CI 1.159-1.701, P=0.001) took ifrst place for predicting the 1 year re-admission and pericardial effusion took second place (HR=1.410, 95%CI 1.030-1.928, P=0.032).
Conclusion: MR, TR and pericardial effusion were the independent predictors for 1 year readmission in HFrEF patients;while MR and pericardial effusion were the independent risk factors for 1 year re-admission.
