Non-ischemic cardiomyopathy (NICM) is one of the most important entities for arrhythmias and sudden cardiac death (SCD). Previous studies suggest a lower benefit of implantable cardioverter-defibrillator (ICD) therapy in patients with NICM as compared to ischemic cardiomyopathy (ICM). Nevertheless, current guidelines do not differentiate between the two subgroups in recommending ICD implantation. Hence, risk stratification is required to determine the subgroup of patients with NICM who will likely benefit from ICD therapy. Various predictors have been proposed, among others genetic mutations, left-ventricular ejection fraction (LVEF), left-ventricular end-diastolic volume (LVEDD), and T-wave alternans (TWA). In addition to these parameters, cardiovascular magnetic resonance imaging (CMR) has the potential to further improve risk stratification. CMR allows the comprehensive analysis of cardiac function and myocardial tissue composition. A range of CMR parameters have been associated with SCD. Applicable examples include late gadolinium enhancement (LGE), T1 relaxation times, and myocardial strain. This review evaluates the epidemiological aspects of SCD in NICM, the role of CMR for risk stratification, and resulting indications for ICD implantation.

Background: Differentiated thyroid carcinoma (DTC) is the most common pediatric thyroid malignancy, with papillary thyroid carcinoma (PTC) representing 90% of the cases. In 2015, the American Thyroid Association (ATA) developed management guidelines for pediatric DTC.

Procedure: Patients less than 21 years of age diagnosed with DTC between 2000 and 2015 at Texas Children's Hospital, Seattle Children's Hospital, Children's Healthcare of Atlanta, Children's Hospital Colorado, and Nationwide Children's Hospital were retrospectively analyzed to evaluate treatment practices before the implementation of the ATA guidelines.

Mortality risk stratification for Takotsubo syndrome: Evaluating CRP measurement alongside the InterTAK prognostic score.

ESC Heart Fail

January 2025

Université de Strasbourg, Pôle d'Activité Médico-Chirurgicale Cardio-Vasculaire, Nouvel Hôpital Civil, Centre Hospitalier Universitaire, Strasbourg, France.

Background And Objectives: Initially described as a benign acute cardiomyopathy, Takotsubo syndrome has been linked to elevated mortality rates. Emerging evidence suggests that unresolved myocardial inflammation may contribute to this adverse prognosis. This study aimed to evaluate the incremental prognostic utility of C-reactive protein (CRP) in conjunction with the InterTAK prognosis score for stratifying long-term mortality in Takotsubo syndrome.

Association of Total Mortality and Cardiovascular Endpoints With the Timing of the First and Second Systolic Peak of the Aortic Pulse Wave.

J Clin Hypertens (Greenwich)

January 2025

Department of Cardiovascular Medicine, Shanghai Key Laboratory of Hypertension, Shanghai Institute of Hypertension, State Key Laboratory of Medical Genomics, National Research Centre for Translational Medicine, Ruijin Hospital, Shanghai Jiaotong University School of Medicine, Shanghai, China.

Prognostic significance of the timing in the cardiac cycle of the first (TP1) and second (TP2) systolic peak of the central aortic pulse wave is ill-defined. Incidence rates and standardized multivariable-adjusted hazard ratios (HRs) of adverse health outcomes associated with TP1 and TP2, estimated by the SphygmoCor software, were assessed in the International Database of Central Arterial Properties for Risk Stratification (IDCARS) (n = 5529). Model refinement was assessed by the integrated discrimination (ID) and net reclassification (NR) improvement.

Ischemia with Non-Obstructive Coronary Arteries (INOCA) in the 2024 European Society of Cardiology (ESC) Guidelines for the management of chronic coronary syndromes.

Eur Heart J Acute Cardiovasc Care

January 2025

Cardiovascular Clinical Research Center, Leon H. Charney Division of Cardiology, Department of Medicine, NYU Grossman School of Medicine, New York, NY, USA.

Background: Chronic coronary syndromes (CCS) occur commonly in the absence of flow-limiting epicardial coronary stenoses. Ischemia or angina with no obstructive coronary arteries (INOCA/ANOCA) may be caused by coronary microvascular disease, coronary artery spasm, myocardial bridging, diffuse atherosclerosis, or a combination of disorders.

Methods & Results: We highlight the new recommendations in the 2024 European Society of Cardiology (ESC) guidelines on CCS relevant to the diagnosis and management of INOCA/ANOCA.
