Abstract
Background: Right ventrical function has recently gained attention as a prognostic predictor of outcome event in patients who have left - sided heart failure. Since several convensional echocardiographic parameters of right ventrical function have been proposed, our aim was to determine if any parameters are assosiated with outcome in heart failure reduced ejection fraction.
Methods: 119 heart failure reduced ejection fraction patients were enrolled in this study, followed up and evaluated after 3 - 6 months.
Results: 57,1% patients have right ventrical systolic dysfunction, 80% patients have right ventrical diastolic dysfunction and 46.2% patients have right ventrical diastolic and systolic dysfunction. 50 events (42%) occured :20 deaths (15,8%), 30 readmissions (26,2%). A Kaplan - Meier curve showed that the survival rate of the right ventrical systolic dysfunction group was significaltly lower than group with no right ventrical systolic dysfunction. A multivariate Cox regression model identified that right ventrical systolic dysfunction was an independent predictor of 6 month mortality and readmission.
Conclusion: Righ ventrical systolic dysfunction was an independent predictor in patients with heart failure reduced ejection fraction.
