BACKGROUND: Predictors and implications of early left ventricular ejection fraction (LVEF) improvement with guideline-directed medical therapy (GDMT) in new-onset idiopathic nonischemic cardiomyopathy (NICM) with narrow QRS complex are not well described. The objectives were to describe predictors of LVEF improvement after 3 months on GDMT and adverse cardiac events based on post-GDMT LVEF status (≤35% vs. >35%). METHODS: A retrospective cohort study was performed in subjects with new-onset NICM, LVEF ≤35%, and narrow QRS complex...

For clinical genetic testing of cardiomyopathy (CMP), current guidelines do not address which gene panels to use: targeted panels specific to a CMP phenotype or expanded (panCMP) panels that include genes associated with multiple phenotypic subtypes. Our objective was to assess the clinical utility of targeted versus panCMP panel testing in pediatric CMPs. 151 pediatric patients with primary hypertrophic (n = 66), dilated (n = 64), restrictive (n = 8), or left-ventricular non-compaction (n = 13) CMP who underwent clinical genetic panel testing at a single centre were included...

Background -Current guidelines only recommend the use of an implantable cardioverter defibrillator (ICD) in patients with dilated cardiomyopathy (DCM) for the primary prevention of sudden cardiac death (SCD) in those with a left ventricular ejection fraction (LVEF)<35%. However, registries of out-of-hospital cardiac arrests demonstrate that 70-80% of such patients have a LVEF>35%. Patients with a LVEF>35% also have low competing risks of death from non-sudden causes. Therefore, those at high-risk of SCD may gain longevity from successful ICD therapy...

Aims: The latest 2015 ESC Guidelines on the prevention of sudden cardiac death make a Class IIa recommendation for ICD implantation in patients listed for heart transplantation. This recommendation was based on expert consensus in view of the sparsity of data. Methods and results: All patients listed for heart transplantation at the University Hospitals of Leuven from 2002 until 2014 were studied retrospectively. Exclusion criteria were age <16 years, cardiac disease other than ischaemic or dilated cardiomyopathy and re-transplantation...

BACKGROUND: Primary prevention of sudden cardiac death by means of implantable cardioverter-defibrillators constitutes the holy grail of arrhythmology. However, current risk stratification algorithms lead to suboptimal outcomes, by both allocating ICDs to patients not deriving any meaningful survival benefit and withholding them from those erroneously considered as low-risk for arrhythmic mortality. METHODS: In the present review article we will attempt to present shortcomings of contemporary guidelines regarding sudden death prevention in ischemic and dilated cardiomyopathy patients and present available data suggesting encouraging results following implementation of multifactorial approaches, by using multiple modalities, both noninvasive and invasive...

BACKGROUND: Sudden cardiac death (SCD) is frequent in patients with heart failure due to dilated cardiomyopathy (DCM). Implantable cardioverter/defibrillator (ICD) device therapy is currently used for primary prevention. However, publication of the DANISH trial has recently given reason for doubt, showing no significant improvement in all-cause mortality in comparison to contemporary medical therapy. METHODS: We performed a meta-analysis of all randomized controlled trials comparing ICD therapy to medical therapy (MT) for primary prevention in DCM...

PURPOSE OF REVIEW: Truncating variants in the TTN gene (TTNtv) are frequently identified in patients with dilated cardiomyopathy (DCM) but are also present in apparently healthy people in the general population. Consequently, there is considerable uncertainty about what it means for any single individual if a TTNtv is found. The aim of this review is to summarize current evidence implicating TTNtv in DCM pathogenesis and to provide some interpretative guidelines for clinical management...

AIMS: Our goal was to identify the prevalence of aortic dilation in patients with hypertrophic cardiomyopathy (HCM), the most prevalent (0.2%) heritable, genetic cardiovascular disease. Aortic dilation also represents a spectrum of familial inheritance. However, data regarding the prevalence of aortic dilation in HCM patients is lacking. METHODS AND RESULTS: This is an observational retrospective study of all patients referred to our HCM centre. Aortic dilation was defined based on recent American Society of Echocardiography and European Association of Cardiovascular Imaging published guidelines...

Increasing numbers of patient relatives at risk of developing dilated or hypertrophic cardiomyopathy (DCM/HCM) are being identified and followed up by cardiologists according to the ACC/ESC guidelines. However, given limited healthcare resources, good-quality low-cost alternative approaches are needed. Therefore, we have compared conventional follow-up by a cardiologist with that provided at a cardiogenetic clinic (CGC) led by a genetic counsellor. Phenotype-negative first-degree relatives at risk for DCM/HCM were randomly assigned to see either a cardiologist or to attend a CGC...

Acute myocarditis is a disorder characterized by an unpredictable clinical course which ranges from asymptomatic, incidentally discovered forms, to cases with fulminant course and adverse outcome. The most challenging issues in the context of acute myocarditis are the appearance of difficult to treat heart failure in the acute phase and the potential progression in the long-term to dilated cardiomyopathy. Areas covered: With respect to available treatment options in acute myocarditis, in the absence of specific guidelines, management is supportive and overall empirical, especially for the oligo- or asymptomatic patients with preserved ejection fraction...

Background. Inflammation plays a crucial role in the progression of chronic heart failure (CHF). Ivabradine is known to reduce the morbidity and mortality of patients with CHF under certain conditions. Beyond the reduction of heart rate, only limited knowledge exists about potential anti-inflammatory effects of ivabradine that might contribute to its benefit in CHF. Thus, the present study aimed to investigate the effect of ivabradine on systemic inflammation. Methods. In the present study, 33 patients with CHF due to dilated, ischemic, and hypertensive cardiomyopathy were treated with ivabradine according to the guidelines of the European Society of Cardiology (ESC)...

Heart failure is a major public issue, and dilated cardiomyopathy (DCM) is one of the common etiologies of heart failure. DCM is generally progressive, and some patients with DCM need heart transplant despite optimal medical and mechanical therapy. Current guidelines recommend inhibitors of renin-angiotensin-aldosterone system, namely angiotensin-converting-enzyme (ACE) inhibitor, angiotensin receptor blocker (ARB), and mineralocorticoid receptor antagonist as well as beta-blockers for the medical treatment of heart failure with reduced ejection fraction, including DCM...

Hypertension is the most common risk factor for systolic and diastolic heart failure. Based on population-attributable risks, hypertension has the greatest impact on the development of heart failure, accounting for 39% of HF events in men and 59% in women. Higher blood pressure, longer duration of hypertension and older age are associated with higher incidence of heart failure however, long term control of hypertension reduces the risk of heart failure. Thus current guideline pointed the hypertension as the single most important modifiable risk factor for heart failure...

Cardiac involvement of sarcoid lesions is diagnosed by myocardial biopsy which is frequently false-negative, and patients with cardiac sarcoidosis (CS) who have impaired left ventricular (LV) systolic function are sometimes diagnosed with dilated cardiomyopathy (DCM). Late gadolinium enhancement (LE) in magnetic resonance imaging is now a critical finding in diagnosing CS, and the novel Japanese guideline considers myocardial LE to be a major criterion of CS. This article describes the value of LE in patients with CS who have impaired LV systolic function, particularly the diagnostic and clinical significance of LE distribution in comparison with DCM...

The National Institute for Health and Care Excellence (NICE) updated its guidelines for chronic heart failure (HF) in 2010. This re-audit assessed interim improvement as compared with an audit in 2011. Patients with HF (preserved and reduced ejection fraction) attending a tertiary cardiac centre over a 2-year period (January 2013-December 2014) were audited. The data collected included demographics, HF aetiology, medications, clinical parameters and cardiac rehabilitation. In total, 513 patients were audited...

We aimed to elucidate the relationship between glycated hemoglobin (HbA1c), cardiac systolic/diastolic function, and heart failure (HF) prognosis during guideline-directed medical therapy in patients with nonischemic dilated cardiomyopathy (NIDCM). We evaluated 283 hospitalized NIDCM patients, who were grouped according to baseline (BL) and 1-year (1Y) levels of HbA1c (<6.0, 6.0-6.9, and ≥7.0 %). The primary endpoint was defined as either readmission for HF worsening or cardiac death. Approximately half of the patients had BL- or 1Y-HbA1c ≥6...

BACKGROUND AND RATIONALE: In patients with ischemic or non-ischemic cardiomyopathy and impaired left ventricular ejection fraction, treatment with implantable cardioverter-defibrillator (ICD) has been shown to improve survival and guidelines recommend their use for primary prevention of sudden cardiac death. Experts disagree regarding the validity of decade-old trial results as the basis for this recommendation, therefore, reconsideration of prophylactic ICD treatment is needed. EU-CERT-ICD, DANISH-ICD AND DO-IT: In order to update the evidence on prophylactic ICD treatment, several prospective studies are underway in Europe...

INTRODUCTION: Dilated cardiomyopathy (DCM) is the most common cardiomyopathy and occurs often in families. As an inherited disease, understanding the significance of diagnostic procedures and genetic screening within families is of utmost importance. AREAS COVERED: Genetic studies have shown that in 30-40% of familial DCM (FDC) cases a causative genetic mutation can be identified. Successful genetic analysis is highly dependent on close examination of patient and family history, and clinical guidelines exist recommending genetic testing to aid in the evaluation of family members at risk of developing FDC...

Genetic disorders that disrupt the structure and function of the cardiovascular system and the peripheral nervous system are common enough to be encountered in routine cardiovascular practice. Although often these patients are diagnosed in childhood and come to the cardiologist fully characterized, some patients with hereditary neuromuscular disease may not manifest until adulthood and will present initially to the adult cardiologist for an evaluation of an abnormal ECG, unexplained syncope, LV hypertrophy, and or a dilated cardiomyopathy of unknown cause...
