Abstract Background Cardiac sympathetic nerve dysfunction, which is assessed by I-123 metaiodobenzylguanidine (MIBG) imaging, is associated with the poor outcomes in patients with chronic heart failure (CHF). Serial evaluation of cardiac MIBG imaging was shown to be useful for predicting adverse outcome in CHF. However, there was no information available on long-term serial changes of cardiac sympathetic nerve dysfunction after discharge of acute decompensated heart failure (ADHF) hospitalization. Purpose We aimed to clarify the serial change of cardiac MIBG imaging parameter in long-term after discharge of heart failure hospitalization, especially relating to HFrEF (LVEF<40%), HFmrEF (40%≤LVEF<50%) and HFpEF (LVEF≥50%). Methods We studied 112 patients (HFrEF; n=44, HFmrEF; n=23 and HFpEF; n=45) who were admitted for ADHF, discharged with survival and without heart failure hospitalization during follow-up period. All patients underwent cardiac MIBG imaging at the timing of discharge, in 6–12 months and in 18–24 months after discharge. The cardiac MIBG heart to mediastinum ratio (H/M) was calculated on the early image and the delayed image (late H/M). The cardiac MIBG washout rate (WR) was calculated from the early and delayed planar images after taking radioactive decay of I-123 into consideration. Results In HFrEF patients, late H/M was significantly improved from discharge to 6–12 months data (1.60±0.24 vs 1.75±0.31, p<0.0001). Late H/M of HFmrEF patients was also significantly improved from discharge to 18–24 months data (1.71±0.27 vs 1.84±0.29 p=0.043). On the other hand, late H/M of HFpEF patients was not significantly changed. As for WR, WR in HFrEF and HFmrEF patients was significantly improved from discharge to 18–24 months data, although WR of HFpEF was not significantly changed. Conclusion The improvement in cardiac sympathetic nerve dysfunction was observed in patients with HFrEF and HFmrEF, not in HFpEF, after the discharge of acute heart failure hospitalization.

Abstract Aims Cardiac 123I-metaiodobenzylguanidine (123I-MIBG) imaging provides prognostic information in patients with chronic heart failure (HF). However, there is little information available on the prognostic role of cardiac 123I-MIBG imaging in patients admitted for acute decompensated heart failure (ADHF), especially relating to reduced ejection fraction [HFrEF; left ventricular ejection fraction (LVEF) < 40%], mid-range ejection fraction (HFmrEF; 40% ≤ LVEF < 50%) and preserved ejection fraction (HFpEF; LVEF ≥ 50%). Methods and results We studied 349 patients admitted for ADHF and discharged with survival. Cardiac 123I-MIBG imaging, echocardiography, and venous blood sampling were performed just before discharge. The cardiac 123I-MIBG heart-to-mediastinum ratio (late H/M) was measured on the chest anterior view images obtained at 200 min after the isotope injection. The endpoint was cardiac events defined as unplanned HF hospitalization and cardiac death. During a follow-up period of 2.1 ± 1.4 years, 128 patients had cardiac events (45/127 in HFrEF, 28/78 in HFmrEF, and 55/144 in HFpEF). On multivariable Cox analysis, late H/M was significantly associated with cardiac events in overall cohort (P = 0.0038), and in subgroup analysis of each LVEF subgroup (P = 0.0235 in HFrEF, P = 0.0119 in HFmEF and P = 0.0311 in HFpEF). Kaplan–Meier analysis showed that patients with low late H/M (defined by median) had significantly greater risk of cardiac events in overall cohort (49% vs. 25% P < 0.0001) and in each LVEF subgroup (HFrEF: 48% vs. 23% P = 0.0061, HFmrEF: 51% vs. 21% P = 0.0068 and HFpEF: 50% vs. 26% P = 0.0026). Conclusion Cardiac sympathetic nerve dysfunction was associated with poor outcome in ADHF patients irrespective of HFrEF, HFmrEF, or HFpEF.

Backgrounds: Liver dysfunction has a prognostic impact on the outcome of patients with advanced heart failure. A model of end-stage liver disease excluding INR (MELD-XI) is a robust scoring system of liver dysfunction, and a high score has been shown to be associated with poor prognosis in patients with heart failure. However, there is little information available on the long-term prognostic significance of MELD-XI score in patients admitted with acute decompensated heart failure (ADHF), relating to reduced or preserved left ventricular ejection fraction (HFrEF or HFpEF). Methods and Results: We studied 303 consecutive patients admitted with ADHF and discharged with survival (HFrEF(LVEF<50%); n=163, HFpEF;n=140). MELD-XI score was calculated by the following formula: 5.11[[Unable to Display Character: &#65381;]]ln(bilirubin)+11.79[[Unable to Display Character: &#65381;]]ln(creatinine)+9.44. During a follow-up period of 5.0±4.3 yrs, 75 patients had cardiovascular death (CVD). Receiver-operator curve analysis revealed that MELD-XI score of 12 was a fair discriminator for CVD (AUC 0.704 (95%CI 0.635-0.772), p<0.0001; sensitivity 67% and specificity 62%). In HFrEF group, MELD-XI score was significantly independently associated with CVD (p=0.0037) at multivariate Cox analysis, and patients with high MELD-XI score (≥12) had a higher risk of CVD than those with low MELD score (46% vs 24%, p=0.0038, hazard ratio: 2.20 (95%CI 1.27-3.79)). In HFpEF group, MELD-XI score was also significantly independently associated with CVD (p=0.005) at multivariate Cox analysis, and patients with high MELD-XI score (≥12) had a higher risk of CVD (34% vs 8%, p<0.0001, hazard ratio: 6.25 (95%CI 2.59-15.05)). Conclusion: A MELD-XI scoring system would provide the long-term prognostic information in patients admitted with ADHF, regardless of HFrEF or HFpEF.

Introduction: Cardiac iodine-123 metaiodobenzylguanidine (MIBG) imaging has been shown to provide prognostic information in patients with chronic heart failure. However, little is known about the prognostic value of cardiac MIBG imaging in patients admitted with acute decompensated heart failure (ADHF). Hypothesis: We assessed the hypothesis that cardiac MIBG imaging might also be useful for the prediction of poor clinical outcome in patients admitted with ADHF. Methods: We studied 115 consecutive patients admitted for ADHF from October 2011 to January 2013 and discharged with survival (age: 74±13 years, male: 56%, NYHA class at discharge: 2.2±0.8, left ventricular ejection fraction measured by echocardiography: 47.1±15.5%). Cardiac MIBG imaging, echocardiography and venous blood sampling were performed just before discharge. The cardiac MIBG heart-to-mediastinum ratio (H/M) and washout rate were calculated from the chest anterior view images obtained at 20 and 200min after isotope injection. The endpoints were unplanned hospitalization for worsening heart failure (WHF) and pump failure death (PFD). Results: During a follow-up period of 2.0±0.8 years, 32 patients had WHF and 15 patients had PFD. At multivariate Cox analysis, out of the variables including clinical, hemodynamic, biochemical, echocardiographic and MIBG parameters, H/M on delayed image (late H/M) was independently associated with WHF (p=0.0003) and PFD (p=0.0255), although brain natriuretic peptide showed the significant association with the endpoints at univariate analysis. Kaplan-Meier analysis showed that the patients with late H/M <1.65 (mean value) had a significantly higher risk of both WHF and PFD than those with late H/M ≧1.65 (Figure). Conclusions: Cardiac MIBG imaging could predict poor outcome even in patients admitted with ADHF.

Abstract Background Concomitant presence of pulmonary hypertension in heart failure is associated with increased adverse events and may be related to interventricular uncoupling and impaired cardiac efficiency. It has recently been shown that an increased mean pulmonary artery pressure to mean systemic arterial pressure ratio (MPS ratio), a marker of interventricular coupling and efficiency, is associated with worse clinical outcomes in patients with advanced heart failure. However, there is little information available on the long-term prognostic value of MPS ratio in patients with acute decompensated heart failure (ADHF), relating to reduced or preserved left ventricular ejection fraction (HFrEF or HFpEF). Methods and results We studied 240 patients admitted for ADHF, who underwent right heart catheterization and were discharged with survival (HFrEF (LVEF≤40%); n=110, HFpEF (LVEF>40%); n=130). MPS ratio was obtained at the admission. During a mean follow-up period of 5.2±4.4 yrs, 59 patients had cardiovascular death (CVD). In both groups with HFrEF and HFpEF, MPS ratio was significantly greater in patients with than without CVD (HFrEF; 0.453±0.101 vs 0.382±0.116, p=0.0035, HFpEF; 0.374±0.118 vs 0.323±0.083, p=0.0091). At multivariate Cox regression analysis, MPS ratio was significantly associated with CVD, independently of eGFR and serum sodium level in HFrEF and HFpEF groups. Patients with high MPS ratio (>0.386 in HFrEF and >0.415 in HFpEF determined by ROC curve analysis) had a significantly increased risk of CVD than those with low MPS ratio in both groups. Conclusions MPS ratio could provide the long-term prognostic information in patients admitted for ADHF, regardless of reduced or preserved LVEF.

Background It remains unclear whether beta‐blocker use at hospital admission is associated with better in‐hospital outcomes in patients with acute decompensated heart failure. Methods and Results We evaluated the factors independently associated with beta‐blocker use at admission, and the effect of beta‐blocker use at admission on in‐hospital mortality in 3817 patients with acute decompensated heart failure enrolled in the Kyoto Congestive Heart Failure registry. There were 1512 patients (39.7%) receiving, and 2305 patients (60.3%) not receiving beta‐blockers at admission for the index acute decompensated heart failure hospitalization. Factors independently associated with beta‐blocker use at admission were previous heart failure hospitalization, history of myocardial infarction, atrial fibrillation, cardiomyopathy, and estimated glomerular filtration rate <30 mL/min per 1.73 m 2 . Factors independently associated with no beta‐blocker use were asthma, chronic obstructive pulmonary disease, lower body mass index, dementia, older age, and left ventricular ejection fraction <40%. Patients on beta‐blockers had significantly lower in‐hospital mortality rates (4.4% versus 7.6%, P <0.001). Even after adjusting for confounders, beta‐blocker use at admission remained significantly associated with lower in‐hospital mortality risk (odds ratio, 0.41; 95% CI, 0.27–0.60, P <0.001). Furthermore, beta‐blocker use at admission was significantly associated with both lower cardiovascular mortality risk and lower noncardiovascular mortality risk. The association of beta‐blocker use with lower in‐hospital mortality risk was relatively more prominent in patients receiving high dose beta‐blockers. The magnitude of the effect of beta‐blocker use was greater in patients with previous heart failure hospitalization than in patients without ( P for interaction 0.04). Conclusions Beta‐blocker use at admission was associated with lower in‐hospital mortality in patients with acute decompensated heart failure.
