AbstractCurrent echocardiography techniques have allowed more precise assessment of cardiac structure and function of the several types of cardiomyopathies. Parameters derived from echocardiographic tissue imaging (ETI) —tissue Doppler, strain, strain rate, and others—are extensively used to provide a framework in the evaluation and management of cardiomyopathies. Generally, myocardial function assessed by ETI is depressed in all types of cardiomyopathies, non-ischemic dilated cardiomyopathy (DCM) in particular . In hypertrophic cardiomyopathy (HCM), ETI is useful to identify subclinical disease in family membe...

We report a rare case of rhinovirus infection in a patient with myocarditis leading to dilated cardiomyopathy. Infection is an established cause of myocarditis. Prodromal “flu-like” symptoms in a young patient with unexplained heart failure should raise concern for viral myocarditis. Diagnosis is often made by clinical presentation and not by endomyocardial biopsy due to invasiveness. Polymerase chain reaction is a rapid test that supports the diagnosis and may elucidate the role of the virus in myocarditis. Defining causes and mechanisms leading to this severe cardiovascular condition may prove critical to tar...

We examined the correlates of R-V/A and traditional echocardiographic indices of RVSD, over the spectrum of pulmonary hypertension and tertiles of mean pulmonary artery pressures (PAPm). Methods In 2016–2017, we studied 81 consecutive patients for heart transplant/advanced heart failure. Inclusion criteria were NIDCM, reduced ejection fraction (≤40%) and sinus rhythm. R-V/A was computed as the RV/pulmonary elastances ratio (R-Elv/P-Ea), derived from a combined right heart catheterization/transthoracic- echocardiographic assessment [right heart catheterization/transthoracic-echocardiographic (RHC/TTE)]. Results...

Conclusion: In this study, the significant difference between the electrocardiographic data of deceased and surviving dilated cardiomyopathy patients suggests that electrocardiographic data should be evaluated in detail in order to determine the low and high risk of mortality in patients with dilated cardiomyopathy.What is Known:•Previous studies on the relationship between limited electrocardiography data of adult patients diagnosed with DCM and mortality have been determinedWhat is New:•ECG data has not been investigated in such detail in child DCM patients,as in our study.

Conclusions: The degradation of cytokine mRNA by Regnase-1 in cardiomyocytes plays an important role in restraining sterile inflammation in failing hearts and the Regnase-1-mediated pathway might be a therapeutic target to treat patients with heart failure.

AbstractIndications of cardiac resynchronization therapy (CRT) do not include exercise ‐induced left bundle branch block, but functional impairment could be improved with CRT in such cases. A 57‐year‐old woman with idiopathic dilated cardiomyopathy (ejection fraction 23%) presented with New York Heart Association Class IV and recurrent hospitalizations. During heart transplant e valuation, a new onset of intermittent left bundle branch block was observed on the cardiopulmonary exercise test. CRT was implanted, and 97% resynchronization rate was achieved. In 12 month follow‐up, both clinical and prognostic exercise ...

AbstractIn humans, it is acknowledged that dilated cardiomyopathy is also caused by infection-induced myocarditis. To evaluate whether the occurrence of lesions of dilated cardiomyopathy in cattle may be triggered by myocarditis, an adult Holstein-Friesian dairy cow which showed dilated cardiomyopathy associated with myocarditis was examined by histopathology. Traumatic pericarditis or idiopathic congestive heart failure was clinically suspected, and the animal was culled because of unfavorable prognosis. Histopathological examination revealed an intrinsic cardiomyopathic lesion that overlapped with myocarditis. Cardiomyoc...

Conclusions: Univariate Cox regression analysis did not prove T-cad to be an outcome predictor (HR = 1, p = 0.349). However, decreased T-cad levels in human myocardium can be an additional indicator of HF severity. T-cad in human myocardium has an anti-inflammatory role. More studies are needed to extend the role of T-cad in the outcome prediction of patients with NI-DCM. PMID: 31936691 [PubMed - in process]

In this study, we aimed to profile gene expression signatures and identify novel genes associated with DCM through a quantitative meta-analysis of three publicly available RNA-seq studies using human left ventricle tissues from 41 DCM cases and 21 control samples. Our meta-analysis identified 789 DEGs including 581 downregulated and 208 upregulated genes. Several DCM-related genes previously reported, including MYH6, CKM, NKX2–5 and ATP2A2, were among the top 50 DEGs. Our meta-analysis also identified 39 new DEGs that were not detected using those individual RNA-seq datasets. Some of those genes, including PTH1R,...

Authors: Poglajen G, Ksela J, Frljak S, Zemljic G, Boznar Alic E, Cerar A, Vrtovec B Abstract Background: Galectin-3 plasma levels (gal-3) were shown to correlate with the scar burden in chronic heart failure (CHF) setting. As scar burden predicts response to stem cell therapy, we sought to explore a correlation between gal-3 and response to CD34+ cell transplantation in patients with CHF. Methods: We performed a post hoc analysis of patients, enrolled in 2 prospective trials investigating the clinical effects of CD34+ cell therapy in patients with ischemic cardiomyopathy (ICMP) and nonischemic dilated cardiomy...
