- Background: Acute heart failure (AHF) is the first cause of hospitalization for over-65 individuals, associated with high mortality and readmission rate. The aim of this study was to assess the prognostic value of a multiparametric score combining clinical, biochemical and echocardiographic indexes in AHF for clinical practice.Methods: 830 patients hospitalized for AHF were enrolled. Exclusion criteria were: active neoplasms; previous heart transplantation or left ventricular assist device implantation. Different variables were analyzed: etiology of AHF, clinical and biochemical data, lung congestion on chest-X ray, echocardiographic parameters and administered therapy. The endpoints were: all-cause mortality at 30 days, 6 months and 5 years and the duration of hospitalization.Results: 771 patients met eligibility criteria. Using the univariate and multivariate analysis the indexes with the best correlation with outcome were discretized and used to create the ACUTE HF score, computed as: 1.4*[serum creatinine>2 mg/dl] + 0.8*[ejection fraction<30] + 0.7*[age > 76] + 0.7*[prior hospitalization for AHF] + 0.9*[prior stroke/transient ischemic attack] + 0.5*[more than moderate mitral regurgitation] + 0.8*[use of non-invasive ventilation] and used to divide patients into 3 groups according to the risk of 6-months mortality. With the receiver operating curves and Kaplan-Meier analysis, this score proved to have a high predictive power for mortality at 30 days, 6 months and 5 years from hospitalization, and for event-free survival rates, providing a risk stratification capability superior to that of single variables.Conclusions: The ACUTE HF score could be a complete and useful tool for assessing prognosis of AHF patients. It could represent a step in the long standardization pathway of prognostic protocols for AHF.

- The aim of the present study was to explore the relation between right ventricular (RV) and left ventricular (LV) echocardiographic parameters with clinical outcome in patients with advanced heart failure referred for cardiac transplantation. Ninety-eight consecutive patients with advanced systolic heart failure, referred for cardiac transplant evaluation, were enrolled. All patients were prospectively followed for the development of new outcome events, which included hospitalization for acute heart failure, cardiovascular death, heart transplantation, intra-aortic balloon pump implantation, and ventricular assist device implantation. Conventional transthoracic echocardiography was performed in all subjects. RV longitudinal strain (RVLS) by speckle-tracking echocardiography was assessed by averaging all segments in apical 4-chamber view (global RVLS) and by averaging RV free-wall segments (free-wall RVLS). LV global longitudinal and global circumferential strains were also calculated. Of the 98 subjects at baseline, 46 had 67 new events during a mean follow-up of 1.5 +/- 0.9 years. Free-wall RVLS, global RVLS, N-terminal fragment of the prohormone brain natriuretic peptide, RV fractional area change, and LV end-diastolic volume were independently predictive of combined outcomes (all p<0.0001). The overall performance for the prediction of cardiovascular events was greatest for free-wall RVLS (area under the curve free-wall RVLS: 0.87; global RVLS: 0.67; RV fractional area change: 0.60; N-terminal fragment of the prohormone brain natriuretic peptide, 0.62; global circumferential strain: 0.55; global longitudinal strain: 0.35; and LV ejection fraction: 0.26). Free-wall RVLS showed the highest adjusted hazards ratio. A graded association between the grade of RV dysfunction and the risk of cardiovascular events was only evident for free-wall RVLS and global RVLS. In conclusion, in patients referred for heart transplantation, RVLS is a stronger predictor of outcome than LV longitudinal strain and other conventional parameters, providing a stronger prognostic stratification.

- BACKGROUND: Levosimendan is a calcium sensitizer and K(+)-ATP channel opener with inotropic and vasodilatatory effects irrespective of myocardial oxygen consumption, used for treatment of heart failure (HF). A loading dose is usually given by infusion for 12 h; however, profound lowering of blood pressure often disrupts or prolongs the infusion. The aim of this study was to assess clinical, biochemical and myocardial differences between different regimes of levosimendan therapy, with or without loading dose, and compared to standard therapy in heart failure.METHODS: Fifty-seven patients (mean age ± SD: 60.9 ± 9.3 years, 45 males) with HF, New York Heart Association (NYHA) III-IV, reduced left ventricular ejection fraction (LVEF) were included. Twenty patients (NB group) were given levosimendan without loading dose, 14 patients (B group) were given levosimendan with loading dose, and 23 patients (C group) were given standard therapy. Clinical, biochemical and echocardiographic characteristics at baseline and one week after treatment were evaluated.RESULTS: Groups were similar at baseline. After one week NHYA class (P < 0.001), NT pro-BNP (P < 0.001), LVEF (P = 0.045), E/A (P = 0.048) E/e' (P < 0.001), and PAPs (P < 0.001) decreased. DT (P = 0.011) and TAPSE (P = 0.035) increased in all groups.CONCLUSIONS: Levosimendan, as well as standard therapy, improves myocardial function and symptoms of HF, irrespective of the loading dose administration. Treatment options for patients with end-stage heart failure refractory to conventional medical therapy are limited. Inotropic drugs play an important role in heart failure (HF).
