Abstract 12830: Prognostic Significance of the Right Ventricular Dimension on Acute Decompensation in Chronic Left-sided Heart Failure

Introduction: Although many reports have shown that right ventricular (RV) function in the compensatory phase has prognostic significance of chronic heart failure (HF), there have been few reports investigating its clinical significance on acute exacerbation. Methods: One hundred and twenty-three consecutive patients (67±15 yo, 95 men) admitted for dyspnea derived from exacerbated left-sided HF with a left ventricular ejection fraction (LVEF) Results: There were 14 cardiac deaths during the median follow-up of 422 days after admission. Multivariate analysis revealed that RVDd on admission (hazard ratio 1.109, p Conclusion: Enlarged RVDd on HF exacerbation predicted a worse long-term prognosis of left-sided HF presumably through facilitated low cardiac output.
