Background:Mesenchymal stem cells (MSCs), which have the potential to differentiate into cardiomyocytes or vascular endothelial cells, have been used clinically as therapy for cardiomyopathy. In this study, we aimed to evaluate the long-term follow-up results.Methods and Results:We studied 8 patients with symptomatic heart failure (HF) on guideline-directed therapy (ischemic cardiomyopathy, n=3; nonischemic cardiomyopathy, n=5) who underwent intracardiac MSC transplantation using a catheter-based injection method between May 2004 and April 2006. Major adverse events and hospitalizations were investigated up to 10 years afterward. Compared with baseline, there were no significant differences in B-type natriuretic peptide (BNP) (from 211 to 173 pg/mL), left ventricular ejection fraction (LVEF) (from 24% to 26%), and peak oxygen uptake (from 16.5 to 19.2 mL/min/kg) at 2 months. During the follow-up period, no patients experienced serious adverse events such as arrhythmias. Three patients died of pneumonia in the 1st year, liver cancer in the 6th year, and HF in the 7th year. Of the remaining 5 patients, 3 patients were hospitalized for exacerbated HF, 1 of whom required heart transplantation in the 2nd year; 2 patients survived for 10 years without worsening HF.Conclusions:The results of this exploratory study of intracardiac MSCs administration suggest further research regarding the feasibility and efficacy is warranted.

Background: In heart failure (HF) management, early ambulation is recommended to prevent physical deconditioning. The effects of delayed ambulation on later clinical outcomes and the factors linked to delayed ambulation in hospitalized HF patients, however, remain unestablished. Methods and Results: We retrospectively investigated 101 patients (mean age, 66±17 years) who were hospitalized for acute decompensated HF. During the mean follow-up of 244±15 days after hospital discharge, 34 patients had cardiovascular events leading to death or unplanned readmission. Patients with cardiovascular events had longer median days to acquire ambulation than those without cardiovascular events (11 days, IQR, 8–20 days vs. 7 days, IQR, 5–15 days, P<0.001). The optimal cut-off period until initiation of ambulation to discriminate cardiovascular events was 8 days, indicating that longer days (≥8 days) to acquire ambulation was associated with higher rates of cardiovascular events, even after adjustment of multiple confounders. On multivariate analysis, age >65 years (odds ratio [OR], 2.49; 95% confidence interval [CI]: 1.04–6.09) and increase in blood urea nitrogen (BUN; OR, 1.04; 95% CI: 1.01–1.08) were independent predictors of delayed ambulation. Conclusions: Delayed ambulation is associated with older age and increased BUN in patients with acute HF. Time to ambulation in the recovery phase of acute HF is important, and delayed ambulation may increase the rate of cardiovascular events after hospital discharge.

Background: Early ambulation has been shown to be associated with shorter hospital stay and better clinical outcomes in patients with acute heart failure (HF). Early mobilization program in combination with structured exercise training is recommended, but has yet to be developed and implemented in HF. Methods and Results: We developed a progressive mobilization program for HF patients that classifies the mobilization process into 7 stages based on disease condition and physical function. We retrospectively analyzed 136 patients with acute HF (80±11 years), who were assigned either to the mobilization program (intervention group, n=75) or to usual care (control group, n=61). The program was safely implemented without any adverse events. Hospital stay was significantly reduced in the intervention group compared with the control group (33±25 vs. 51±36 days, P<0.01). The intervention group had higher activities of daily living (ADL) score at discharge evaluated using the Barthel index (64±38 vs. 49±36, P<0.05). The intervention group also had a higher percentage of discharge to home (71% vs. 52%, P<0.05) and a lower rate of HF-related readmission (16% vs. 36%, P<0.05) compared with the control group. Conclusions: The progressive mobilization program for acute HF was feasible and was associated with better ADL and reduced hospital stay, leading to improvement of clinical outcome.

Background: Acute kidney injury (AKI) and acute hyperglycemia are associated with unfavorable outcomes. The impact of acute hyperglycemia on the development of AKI after acute myocardial infarction (AMI), however, remains unclear. This study was undertaken to assess the relationship between admission glucose and incidence of AKI after AMI. Methods and Results: This study consisted of 760 patients with AMI admitted to the National Cerebral and Cardiovascular Center within 48h after symptom onset. Blood sample was obtained on admission and repeated sampling was done at least every 1 or 2 days during the first week. AKI was diagnosed as increase in serum creatinine ≥0.3mg/dl or ≥50% within any 48h. Ninety-six patients (13%) had AKI during hospitalization for AMI, and these patients had higher in-hospital mortality than those without AKI (25% vs. 3%, P<0.001). Patients with AKI had higher plasma glucose (PG) on admission than those without (222±105mg/dl vs. 166±69mg/dl, P<0.001). The incidence of AKI increased as admission PG rose: 7% with PG <120mg/dl; 9% with PG 120–160mg/dl; 11% with PG 160–200mg/dl; and 28% with PG >200mg/dl (P<0.01). On multivariate analysis admission PG was an independent predictor of AKI (odds ratio, 1.10; 95% confidence interval: 1.03–1.18, P=0.02). Conclusions: Admission hyperglycemia might have contributed to the development of AKI in patients with AMI.  (Circ J 2014; 78: 1475–1480)

Prediction models are combinations of predictors to assess the risks of specific endpoints such as the presence or prognosis of a disease. Many novel predictors have been developed, modelling techniques have been evolving, and prediction models are currently abundant in the medical literature, especially in cardiovascular medicine, but evidence is still lacking regarding how to use them. Recent methodological advances in systematic reviews and meta-analysis have enabled systematic evaluation of prediction model studies and quantitative analysis to identify determinants of model performance. Knowing what is critical to model performance, under what circumstances model performance remains adequate, and when a model might require further adjustment and improvement will facilitate effective utilization of prediction models and will enhance diagnostic and prognostic accuracy in clinical practice. In this review article, we provide a current methodological overview of the attempts to implement evidence-based utilization of prognostic prediction models for all potential model users, including patients and their families, health-care providers, administrators, researchers, guideline developers and policy makers.

Heart failure (HF) is associated with aberrant skeletal muscle impairments, which are closely linked to the severity of HF. A low level of brain-derived neurotrophic factor (BDNF), a myokine produced in the skeletal muscle, is known to be involved in reduced exercise capacity and poor prognosis in HF. However, little is known about the factors or conditions of skeletal muscle associated with BDNF levels. We investigated the association between serum BDNF levels and the skeletal muscle mass and function in HF patients (n = 60, 63 ± 13 years) and age-matched controls (n = 29, 61 ± 16 years). The serum BDNF level was significantly lower in the HF patients compared to the controls (24.9 ± 0.9 versus 28.6 ± 1.3, P = 0.021). In a univariate analysis, BDNF was significantly correlated with the peak oxygen uptake, estimated glomerular filtration rate, 10-m gait speed, and muscle strength, but not with the body mass index or lean mass in the HF group. A multiple linear regression analysis revealed that BDNF was independently associated with muscle strength (β-coefficient = 2.80, 95%CI: 1.89-11.8, P = 0.008). Serum BDNF levels were associated with exercise capacity and skeletal muscle function, but not with muscle mass. These novel findings may suggest that BDNF production is controlled by muscle function and activity and consequently regulates exercise capacity, highlighting the importance of adequate training regarding skeletal muscle in HF patients.

Background:Statins might be associated with improved survival in patients with heart failure with preserved ejection fraction (HFpEF). The effect of statins in HFpEF without coronary artery disease (CAD), however, remains unclear.Methods and Results:From the JASPER registry, a multicenter, observational, prospective cohort with Japanese patients aged ≥20 years requiring hospitalization with acute HF and LVEF ≥50%, 414 patients without CAD were selected for outcome analysis. Based on prescription of statins at admission, we divided patients into the statin group (n=81) or no statin group (n=333). We followed them for 25 months. The association between statin use and primary (all-cause mortality) and secondary (non-cardiac death, cardiac death, or rehospitalization for HF) endpoints was assessed in the entire cohort and in a propensity score-matched cohort. In the propensity score-matched cohort, 3-year mortality was lower in the statin group (HR, 0.21; 95% CI: 0.06–0.72; P=0.014). The statin group had a significantly lower incidence of non-cardiac death (P=0.028) and rehospitalization for HF (P<0.001), but not cardiac death (P=0.593). The beneficial effect of statins on mortality did not have any significant interaction with cholesterol level or HF severity.Conclusions:Statin use has a beneficial effect on mortality in HFpEF without CAD. The present findings should be tested in an adequately powered randomized clinical trial.

A 74-year-old man, who had a history of a mitral valve replacement for rheumatic heart disease (RHD) 30 years previously, was admitted with progressive heart failure. Massive calcification was observed around the left atrium on multidetector CT, in addition to a late gadolinium enhancement (LGE)-positive layer adjacently outside of the calcification on MRI. He underwent a second mitral valve replacement for the prosthetic valve failure. Pathohistological analyses of a tissue section of the left atrial wall from a surgical specimen revealed lymphocyte and macrophage infiltration that coincided with the LGE-positive layer on MRI, suggesting the existence of sustained active inflammation even after the long period of RHD.

Background A method of displaying coronary computed tomography (CT) angiography, which enables evaluation of coronary artery disease (CAD) with fewer images and is understandable to the third person, is preferable. Methods and Results A maximum intensity projection image was created in which contrast media in the ventricles is eliminated, enabling an overview of CAD in a single 3-dimensional (D) image that can be rotated to be viewed at various angles and is easily understood by a third person. Conclusions A novel method of displaying coronary CT angiography in a single 3-D image has been developed and we believe it should become available for many workstations.
