Introduction: Several studies have been performed to assess the efficacy of postmortem computed tomography angiography (PMCTA) in solving cases of sudden cardiac death, even in comparison with the traditional autopsy. However, the results were often inconsistent and inconclusive. Therefore, a global discussion on the subject through a systematic review of the literature and a meta-analysis is necessary. Methods: A systematic search of PubMed was performed up to April 23, 2018.

Background: High-risk patients with hypertrophic cardiomyopathy (HCM) are identified by contemporary risk stratification and effectively treated with implantable cardioverter-defibrillators (ICDs). However, long-term HCM clinical course after ICD therapy for ventricular tachyarrhythmias is incompletely understood. Methods and Results: Cohort of 486 high-risk HCM patients with ICDs was assembled from 8 international centers. Clinical course and device interventions were addressed, and survey questionnaires assessed patient anxiety level and psychological well-being related to ICD therapy.

The implantable cardioverter-defibrillator (ICD) is the most effective therapy to prevent sudden cardiac death (SCD) in high-risk patients. To overcome infections and failure of transvenous leads, the most frightening complications of conventional ICDs, a completely subcutaneous ICD (S-ICD) has been developed and is currently adopted in routine clinical practice.

Objective Current guidelines recommend precautionary disqualification from competitive sports in patients with hypertrophic cardiomyopathy (HCM). We assessed the incidence of cardiovascular events in a cohort of patients with HCM engaged in long-term exercise programmes and competitive sport. Methods We reviewed data on 88 consecutive athletes diagnosed with HCM, from 1997 to 2017; 92 male, 98 Caucasian, median age 31 (IQR: 19-44) years. All participated in regular exercise programmes and competitive sport at study entry. We performed follow-up evaluation after 7±5 (1-21) years.

Purpose: Sudden sensorineural hearing loss (SSNHL) has similarities to conditions with vascular etiologies such as myocardial infarction and cerebral stroke. Thus, it could be considered as an early sign of a vascular disease and not only a specific local condition. Chronic hypoperfusion in the brain districts leads to a chronic ischemic damage, called cerebral small vessel disease (CSVD), detectable with brain magnetic resonance imaging (MRI).

Methiopropamine (MPA) is a structural analogue of methamphetamine and belongs to the category of the novel psychoactive substances. To the best of our knowledge, no experimental study has been performed to evaluate the organ damage evoked by MPA administration in an animal model. Therefore, the main purpose of the present study was to investigate the histological changes in CD-1 male mice following the chronic administration of MPA.
