Nonischemic Dilated Cardiomyopathy

Nonischemic dilated cardiomyopathy is deadly and costly, and treatment options are limited. Cardiac rehabilitation has proved safe and beneficial for adults with various types of heart failure. Therefore, we retrospectively evaluated the hypothesis that rehabilitation is safe and improves cardiometabolic health in young patients with nonischemic dilated cardiomypathy. From 2011 through 2015, 8 patients (4 males) (mean age, 20.6 ± 6.6 yr; range, 10–31 yr) underwent rehabilitation at our institution. They were in American Heart Association class C or D heart failure and were on maximal medical therapy. Their mean left ventricular ejection fraction at baseline was 0.26 ± 0.15. Two patients had a left ventricular assist device, and 2 were inpatients. To evaluate safety, we documented adverse events during rehabilitation sessions. Clinical endpoints were measured at baseline, immediately after completing rehabilitation, and after one year. Patients attended 120 of 141 possible sessions (85%), with no adverse events. There were no marked changes in mean left ventricular ejection fraction or body mass index. The patients' mean waist circumference decreased by 1.37 ± 0.6 in (n=5; 95% CI, −2.1 to −0.63). Their 6-minute walk distance increased by a mean of 111 ± 75 m (n=5; 95% CI, 18–205). In our small sample of young patients with nonischemic dilated cardiomyopathy, cardiac rehabilitation was feasible and was associated with minimal risk. Our findings suggest that prospective studies in this population are warranted.

Nonischemic Dilated Cardiomyopathy

To determine the efficacy of intramyocardial injection of angiogenic cell precursors in nonischemic dilated cardiomyopathy, 35 patients with nonischemic dilated cardiomyopathy underwent injections of angiogenic cell precursors into the left ventricle (cell group). Seventeen patients with nonischemic dilated cardiomyopathy were matched from the heart failure database to form a control group that was treated medically. Angiogenic cell precursors were obtained from autologous blood, cultured in vitro, and injected into all free-wall areas of the left ventricle in the cell group. After these injections, New York Heart Association functional class improved significantly by 1.1 ± 0.7 classes at 284.7 ± 136.2 days, and left ventricular ejection fraction improved in 71.4% of patients (25/35); the mean increase in left ventricular ejection fraction was 4.4% ± 10.6% at 192.7 ± 135.1 days. Improved quality of life was demonstrated by better physical function, role-physical, general health, and vitality domains in a short-form health survey at the 3-month follow-up. In the control group, there were no significant improvements in left ventricular ejection fraction or New York Heart Association class which increased by 0.6 ± 0.8 classes. It was concluded that intramyocardial angiogenic cell precursor injection is probably effective in the treatment of nonischemic dilated cardiomyopathy.

Nonischemic Dilated Cardiomyopathy

Background. Recent evidence demonstrated that the circulating levels of omentin-1 are related to the presence of ischemic heart disease and heart failure. However, omentin-1 plasma levels in patients with nonischemic dilated cardiomyopathy (DCM), which is the most common etiology of heart failure, have yet to be investigated.Methods. Plasma levels of omentin-1 and adiponectin were measured in 100 patients with DCM and 45 healthy controls.Results. Plasma omentin-1 levels significantly decreased in DCM patients compared with the control group, whereas adiponectin levels significantly increased in DCM patients compared with the control group. Plasma omentin-1 levels were negatively correlated with adiponectin (R=-0.376,P=0.005), C-reactive protein (CRP) (R=-0.320,P=0.001), and N-terminal pro-brain natriuretic peptide (NT-proBNP) (R=-0.365,P=0.000) levels as well as left ventricular end-diastolic diameter (LVEDD) (R=-0.200,P=0.046) but were positively correlated with left ventricular ejection fraction (LVEF) (R=0.496,P=0.000). Plasma adiponectin levels were positively correlated with CRP (R=0.273,P=0.006) and NT-proBNP (R=0.329,P=0.001) levels but were negatively correlated with fasting glucose (R=-0.218,P=0.029) and LVEF (R=-0.615,P=0.000) levels. Furthermore, omentin-1 (OR 0.983, 95% CI 0.970 to 0.996;P=0.008) levels were independently associated with the presence of DCM before NT-proBNP was added.Conclusions. Omentin-1 is a novel biomarker of DCM.

Abstract Funding Acknowledgements Type of funding sources: Public hospital(s). Main funding source(s): University Medicine Munich University Medicine Greifswald Introduction The vascular cell adhesion molecule-1 (VCAM-1) is overexpressed in a number of different inflammatory processes on activated endothelium. This could be shown in both a mouse model for autoimmune myocarditis and in human heart tissue from patients with lymphocytic myocarditis. In addition to the tissue-bound one, a soluble isoform of VCAM-1 (s-VCAM-1) can also be detected in the blood. Higher levels have been associated with worse clinical outcome in chronic heart failure patients of different etiology and other patient groups. Purpose Since both inflammation and fibrosis are key processes involved in the pathogenesis of dilated cardiomyopathy (DCM) and hypokinetic non-dilated cardiomyopathy (HNDC), we aimed to investigate the prognostic value of s-VCAM-1 plasma levels for survival in a large cohort of DCM and HNDC patients. Methods The cohort comprised of patients with a primary diagnosis of DCM, defined as reduced left ventricular ejection fraction (LVEF <45%), increased left ventricular enddiastolic diameter according to HENRY score (LVEDD >117%) at time of diagnosis as well as HNDC, defined as a reduced left ventricular ejection fraction (LVEF <45%) but no increased LVEDD according to HENRY score (LVEDD < =117%). Exclusion criteria were primary valvular diseases (≥ second degree), acute myocarditis, cancer, chronic alcoholism, coronary artery disease with epicardial stenosis >50%, peripheral artery occlusive disease, known auto-immune disease and heart failure of other origins. Levels of s-VCAM-1 were measured in human plasma using an enzyme-linked immunosorbent assay (R&D Systems, USA). A Cox proportional hazard model for the association between s-VCAM-1 and all-cause mortality was adjusted for age, sex, time since symptom-onset, LVEF, kidney function (eGFR-CKDEPI), CRP and NT-proBNP. Results A total of 334 DCM patients were included in this single-center cohort (78.4 % males) with a mean age of 54.0 years [interquartile range [IQR] 47.0, 63.2). On average time since symptom onset was 1.5 years (IQR 0.1, 1.1), LVEF 30.7 % (IQR 25, 37), LVEDD 67.1 mm (IQR 62, 72). During a median follow-up of 12.4 years (IQR 10.1, 13.9), a total of 118 (35.3 %) patients died. Multivariable-adjusted cox regression model revealed a significantly increased all-cause mortality risk with increasing levels of s-VCAM-1 (p for trend =0.039), (hazard ratio [HR] 1.00045 (Conf. Interval 1.00002, 1.00087) for VCAM increase of 1 ng/mL, for increase of 100 ng/ml HR 1.046 (Conf- interval 1.002, 1.091), for increase of 1000ng/ml HR 1.57 (Conf_interval 1.02-2.41) (Kaplan Meier survival estimates see Figure 1, median s-VCAM-1 = 664 ng/ml, IQR 515,874). Conclusions s-VCAM-1 predicts long-term survival in DCM patients independent of NT-pro-BNP and other risk determinants. Further research needs to evaluate whether this biomarker proves useful in monitoring and planning management of DCM and HNDC patients (e.g. more intensive management in high-risk patients).

Abstract. Vitamin D deficiency commonly occurs in chronic heart failure. Whether additional vitamin D supplementation can be beneficial to adults with chronic heart failure remains unclear. We conducted a meta-analysis to derive a more precise estimation. PubMed, Embase, and Cochrane databases were searched on September 8, 2016. Seven randomized controlled trials that investigated the effects of vitamin D on cardiovascular outcomes in adults with chronic heart failure, and comprised 592 patients, were included in the analysis. Compared to placebo, vitamin D, at doses ranging from 2,000 IU/day to 50,000 IU/week, could not improve left ventricular ejection fraction (Weighted mean difference, WMD = 3.31, 95% confidence interval, CL = −0.93 to 7.55, P < 0.001, I2 = 92.1%); it also exerts no beneficial effects on the 6 minute walk distance (WMD = 18.84, 95% CL = −24.85 to 62.52, P = 0.276, I2 = 22.4%) and natriuretic peptide (Standardized mean difference, SMD = −0.39, 95% confidence interval CL = −0.48 to 0.69, P < 0.001, I2 = 92.4%). However, a dose-response analysis from two studies demonstrated an improved left ventricular ejection fraction with vitamin D at a dose of 4,000 IU/day (WMD = 6.58, 95% confidence interval CL = −4.04 to 9.13, P = 0.134, I2 = 55.4%). The results showed that high dose vitamin D treatment could potentially benefit adults with chronic heart failure, but more randomized controlled trials are required to confirm this result.
