Thyroid ‐stimulating hormone within the normal range and risk of major adverse cardiovascular events in non‐ischemic dilated cardiomyopathy patients with severe left ventricular dysfunction

ConclusionAn association between TSH levels and the risk of VA events may exist in euthyroid NIDCM patients.

AbstractAimsCurrently, the ejection fraction [left ventricular ejection fraction (LVEF)] is the main criterion used for implanting implantable cardioverter defibrillators (ICDs) for primary prevention. However, many of ICD receivers would not have an event and do not have any gains from the device. Consequently, improving the discrimination strategies is needed. Here, we aimed at assessing the role of global longitudinal strain (GLS) for such purpose.Methods and resultsSeventy ischaemic or dilated cardiomyopathy cases characterized by LVEF  ≤ 40% with a previously implanted ICD were enrolled. LVEF and GLS amou...

ConclusionsIn patients with DCM, the annual event rate of sustained ventricular arrhythmias is approximately 4.5%. This risk is considerably higher in younger patients with hypertension, prior (non ‐)sustained ventricular arrhythmia, decreased left ventricular ejection fraction, left ventricular dilatation, late gadolinium enhancement, and genetic mutations (PLN,LMNA, andFLNC). These results may help determine appropriate candidates for implantable cardioverter ‐defibrillator implantation.

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.

AbstractPurpose of ReviewNon-ischaemic dilated cardiomyopathy (DCM) occurs in 1 in 2500 individuals in the general population and is associated with considerable morbidity and mortality. Studies involving large numbers of unselected DCM patients have led to consensus guidelines recommending implantable cardioverter-defibrillator (ICD) implantation for protection against sudden cardiac death (SCD) in those with LVEF ≤35%. The purpose of this article is to review the literature for other potential markers including serological, electrocardiographic, echocardiographic, cardiac magnetic resonance, ambulatory ECG and genetic...

Conclusions: The clinical course of patients with ICM and DCM treated with CRT-D differs significantly during long-term follow-up, with increased mortality and incidence of ICD therapies in ICM patients. PMID: 31360179 [PubMed]

Presence of myocardial fibrosis in well-established non-ischaemic dilated cardiomyopathy (NIDCM) is associated with adverse clinical outcomes. However, the impact of myocardial fibrosis at first presentation in NIDCM, and its long-term association with left ventricular (LV) dysfunction, heart failure (HF) and ventricular arrhythmia (VA) remains unclear. We investigated whether the presence of myocardial fibrosis quantified by late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR) at presentation, is independently associated with long-term major adverse cardiovascular events (MACE) in patients with first presentation NIDCM.

We report a case demonstrating a rapid and potent antiarrhythmic effect of biventricular pacing. A 67-year-old male patient with dilated cardiomyopathy was admitted for heart failure. The initial surface electrocardiogram revealed a left bundle branch block with a QRS complex duration of 200 ms. Echocardiographic examination revealed a left ventricular ejection fraction of 16%, a left ventricular end-diastolic dimension of 91 mm, and marked interventricular dyssynchrony. Continuous rhythm monitoring revealed frequently-recurring non-sustained monomorphic ventricular tachycardia (VT). Polymorphic VT, which persisted for 27 ...

Conclusions: The findings suggest that biologically plausible genetic factors may alter susceptibility to PM10-associated QT prolongation in populations protected by the U.S. Environmental Protection Agency’s National Ambient Air Quality Standards. Independent replication and functional characterization are necessary to validate our findings.

Conclusions Across a wide spectrum of patients with DCM, LGE is strongly and independently associated with ventricular arrhythmia or SCD. LGE could be a powerful tool to improve risk stratification for SCD in patients with DCM. These results raise 2 major questions to be addressed in future studies: whether patients with LGE could benefit from primary prevention ICDs irrespective of their left ventricular ejection fractions, while patients without LGE might not need preventive ICDs despite having severe left ventricular dysfunction.
