Naxos disease is a rare autosomal recessive condition combining arrhythmogenic right ventricular cardiomyopathy, woolly hair, and palmoplantar keratoderma. The first identified causative variant was in the gene encoding the desmosomal protein plakoglobin. Naxos disease exhibits fibro-fatty myocardial replacement with immunohistological abnormalities in cardiac protein and signaling pathways, highlighting the role of inflammation and potential anti-inflammatory treatments.

Aims: To study the impact of genotype on the performance of the 2019 risk model for arrhythmogenic right ventricular cardiomyopathy (ARVC).

Methods And Results: The study cohort comprised 554 patients with a definite diagnosis of ARVC and no history of sustained ventricular arrhythmia (VA). During a median follow-up of 6.

Article Synopsis
  • Identifies the challenge of determining which patients with hypertrophic cardiomyopathy (HCM) are at risk for sudden cardiac death (SCD) and highlights the 2014 HCM Risk-SCD model by the European Society of Cardiology for predicting 5-year risk assessments.* -
  • In a study involving 3,703 patients, only 2% experienced SCD within five years, with the risk model showing effectiveness through a calibration slope of 1.02 and a C-index of 0.70.* -
  • The findings support using the HCM Risk-SCD model to allocate implantable cardioverter defibrillator therapy, leading to better outcomes by targeting high-risk patients more efficiently.*

Aims: To determine the incidence and the causes of sudden death (SD) in persons aged 1-35 years old and the diagnostic yield of clinically guided genetic screening in the sudden arrhythmic death syndrome (SADS) victims' families.

Methods And Results: Incidence and causes of SD in the Attica region of Greece in 2002-10 were determined using death certificates and autopsy reports. We evaluated clinically consecutive families of SADS victims and if a clinical diagnosis was established, we proceeded to targeted genetic analysis.

Introduction: Epsilon waves are hallmark features of arrhythmogenic cardiomyopathy (ACM) but information about their clinical significance is variable. We evaluated epsilon wave prevalence, characteristics, and their clinical significance in an ACM population.

Methods And Results: Eighty-six unselected patients fulfilling the 2010 Task Force criteria were enrolled.

Aims: Arrhythmogenic right-ventricular cardiomyopathy (ARVC) is a genetically determined disorder, mostly caused by mutations in genes encoding desmosomal proteins. We evaluated phenotype/genotype characteristics to predict the risk for the first major arrhythmic event in desmosomal-mutation-associated ARVC families.

Methods And Results: A cohort of 105 desmosomal-mutation carriers belonging to 39 consecutive ARVC families was evaluated.

Objectives: To evaluate the dimensionality of the Greek version of the European Heart Failure Self-care Behaviour Scale (Gr9-EHFScBS) in a Greek-Cypriot population.

Background: EHFScBS is a valid and reliable scale which is widely used for assessing heart failure (HF) patients' self-care behaviors.

Methods: EHFScBS was translated into Greek and was administered to 128 Greek-Cypriot HF patients.

Introduction: So far, no studies have been performed regarding the epidemiology and management of acute coronary syndromes (ACS) in Cyprus. The aim of the present study was to enroll a representative sample of patients in order to study the epidemiology and management of ACS in the Mediterranean island of Cyprus.

Methods: For a period of 12 months, all patients admitted to Nicosia General Hospital with an ACS were studied.

Aims: Primary percutaneous coronary intervention (PPCI) is the preferred reperfusion therapy in ST-elevation myocardial infarction (STEMI). We conducted this study to evaluate the contemporary status on the use and type of reperfusion therapy in patients admitted with STEMI in the European Society of Cardiology (ESC) member countries.

Methods And Results: A cross-sectional descriptive study based on aggregated country-level data on the use of reperfusion therapy in patients admitted with STEMI during 2010 or 2011.

Disclosure of potential conflicts of interest is used by biomedical journals to guarantee credibility and transparency of the scientific process. Conflict of interest disclosure, however, is not systematically nor consistently dealt with by journals. Recent joint editorial efforts paved the way towards the implementation of uniform vehicles for conflicts of interest disclosure.

Introduction: Increased levels of homocysteine are known to be associated with coronary artery disease (CAD). The most common form of genetic hyperhomocysteinemia results from MTHFR polymorphisms. To examine the role of homocysteine levels and MTHFR polymorphisms in premature CAD and acute myocardial infarction (MI) in the Cypriot population, a case control study was performed in Nicosia General Hospital.

Aims: To evaluate arrhythmogenic right ventricular cardiomyopathy/dysplasia (ARVC/D) in affected families with desmosome mutations on the basis of the recently revised Task Force Criteria (TFC).

Methods And Results: One hundred and three consecutive carriers of pathogenic desmosome mutations and 102 mutation-negative relatives belonging to 22 families with dominant and 14 families with recessive ARVC/D were evaluated according to the original and revised TFC. Serial cardiac assessment with 12-lead, signal-averaged, and 24 h ambulatory ECG and two-dimensional echocardiography was performed.

Penetrating heart injuries can be lethal. Here we report a case of self-inflicted cardiac injury with glass fragments by a psychiatric patient. The patient presented with cardiogenic shock and was initially treated surgically for a large pneumothorax and cardiac tamponade.

Background: Lamin proteins A and C are major functional and structural components of the nuclear lamina. Mutations of the LMNA gene have been associated with dilated cardiomyopathy, conduction system defects and skeletal muscle dystrophy simultaneously, in variable involvement. We report on a family with a mutation of the lamin A/C gene (c.
