Identification of cardiac long non-coding RNA profile in human dilated cardiomyopathy

ConclusionsThis study provides a comparison of human cardiac lncRNA profiles in control and DCM. It illustrates the function and complex roles of the differentially expressed lncRNAs in different cell types in the heart, which may lead to new insights into the mechanisms and treatment strategies for DCM in the future.

ConclusionsSubstantial recovery of LV function occurs within 12  months in most patients with recent‐onset DCM. Women had the greatest improvement in LVEF. A low LV contractile reserve measured by dobutamine stress CMR appears to identify patients whose LVEF is less likely to recover.

AbstractDilated cardiomyopathy (DCM) represents one of the primary cardiomyopathies and may lead to heart failure and sudden death. Until recently, ventricular arrhythmias were considered to be a direct consequence of the systolic dysfunction of the left ventricle (LV) and guidelines for implantable cardioverter defibrillator implantation were established on this basis. However, the identification of heritable dilated cardiomyopathy phenotypes that presented with mildly impaired or moderate LV dysfunction, with or without chamber dilatation, and ventricular arrhythmias exceeding the degree of the underlying morphological a...

This study aimed to investigate eligibility, titration, and tolerability for Sac/Val in a real ‐world clinical setting.Methods and resultsThis retrospective cohort study consists of two parts. In Part 1 (eligibility study), all patients discharged from Sahlgrenska University Hospital due to HF were consecutively included during 1 year. Data from the patients' medical records were collected. Patients were adjudicated to be eligible based on European Society of Cardiology (ESC) criteria for angiotensin receptor neprilysin inhibitor (ARNI) with the exception of N ‐terminal (NT)‐proBNP levels. Patients who received

AbstractAimsEchocardiographic response after cardiac resynchronization therapy (CRT) is often lesser in ischaemic cardiomyopathy (ICM) than non ‐ischaemic dilated cardiomyopathy (NIDCM) patients. We assessed the association of heart failure aetiology on the amount of reverse remodelling and outcome of CRT.Methods and resultsNine hundred twenty ‐eight CRT patients were retrospectively included. Reverse remodelling and endpoint occurrence (all‐cause mortality, heart transplantation, or left ventricular assist device implantation) was assessed. Two response definitions [≥15% reduction left ventricular end systolic vo...

AbstractAimsAlthough distinct DNA methylation patterns have been reported, its localization and roles remain to be defined in heart failure. We investigated the cellular and subcellular localization of DNA methylation and its pathophysiological significance in human failing hearts.Methods and resultsUsing left ventricular (LV) endomyocardial biopsy specimens from 75 patients with dilated cardiomyopathy (DCM; age: 58 ± 14 years old, %female: 32%) and 20 patients without heart failure (controls; age: 56 ± 17 years old, %female: 45%), we performed immunohistochemistry and immunoelectron microscopy for methylated...

A 78-year-old woman was admitted because of heart failure. She was known to have nonischemic dilated cardiomyopathy. During the past 2 weeks, she developed severe shortness of breath. The people around her also noticed memory loss and confusion in time and place, suggesting that she was becoming demented. On admission, her daily medication consisted of a β-blocking agent, an angiotensin-converting enzyme inhibitor, a diuretic, and 1/8 mg of digoxin.

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.
