Ectopic heartbeats can trigger reentrant arrhythmias, leading to ventricular fibrillation and sudden cardiac death. Such events have been attributed to perturbed Ca2+ handling in cardiac myocytes leading to spontaneous Ca2+ release and delayed afterdepolarizations (DADs). However, the ways in which perturbation of specific molecular mechanisms alters the probability of ectopic beats is not understood. We present a multiscale model of cardiac tissue incorporating a biophysically detailed three-dimensional model of the ventricular myocyte...

RATIONALE: Brugada syndrome (BrS) is characterized by ST segment elevation at the J point ≥2 mm in the right precordial electrocardiogram (ECG) leads, in the absence of structural heart disease, electrolyte disturbances, or ischemia. It is a well-described cause of sudden death in young patients, especially in the age of between 30 and 40 years old. Here, we reported an unusual case of electrical storm (ES) of ventricular fibrillation (VF) caused by BrS with complete right bundle-branch block (CRBBB) in a 75-year-old male patient...

PURPOSE: Late adverse myocardial remodeling after acute myocardial infarction (AMI) is strongly associated with sudden cardiac death (SCD). Cardiac magnetic resonance (CMR) performed early after AMI can predict late remodeling and SCD risk with moderate accuracy. This study assessed the ability of CMR-measured circumferential strain (CS) to add incremental predictive information to late gadolinium enhancement (LGE). METHODS: Patients with an AMI and LVEF < 50% were screened for inclusion...

BACKGROUND: Population based studies showed an association of early repolarization in the electrocardiogram (ECG) and a higher rate of sudden cardiac death presumably due to ventricular fibrillation. The triggers for ventricular fibrillation in patients with early repolarization are not fully understood. CASE PRESENTATION: We describe the case of a young patient with a survived ventricular fibrillation arrest while asleep followed by multiple episodes of recurrent ventricular fibrillation...

Gastrointestinal conditions are a less common cause of sudden unexpected death when compared to other conditions such as cardiovascular conditions, but they are equally important. Various congenital and acquired gastrointestinal conditions that have resulted in sudden unexpected death are discussed. The possible lethal mechanisms behind each condition, along with any associated risk factors or secondary diseases, have been described. Through this article, we aim to highlight the need for physicians to prevent death in such conditions by ensuring that subclinical cases are diagnosed correctly before it is too late and by providing timely and efficacious treatment to the patient concerned...

Sudden unexpected death in epilepsy (SUDEP) is a devastating epilepsy complication. Seizure-induced respiratory arrest (S-IRA) occurs in many witnessed SUDEP patients and animal models as an initiating event leading to death. Thus, understanding the mechanisms underlying S-IRA will advance the development of preventive strategies against SUDEP. Serotonin (5-HT) is an important modulator for many vital functions, including respiration and arousal, and a deficiency of 5-HT signaling is strongly implicated in S-IRA in animal models, including the DBA/1 mouse...

BACKGROUND: The incidence of sudden cardiac arrest during participation in sports activities remains unknown. Preparticipation screening programs aimed at preventing sudden cardiac arrest during sports activities are thought to be able to identify at-risk athletes; however, the efficacy of these programs remains controversial. We sought to identify all sudden cardiac arrests that occurred during participation in sports activities within a specific region of Canada and to determine their causes...

Sudden unexplained cardiac death (SUCD) can occasionally occur in nonelderly patients with epilepsy, psychiatric disorders, or no medical history. This study was conducted to aim to analyze whether values of the biomarkers for heart failure are associated with the SUCD. Serum concentrations of N-terminal probrain natriuretic peptide, high-sensitivity C-reactive protein (hs-CRP), and tumor necrosis factor α were analyzed in 57 nonelderly patients with SUCD who was diagnosed at medicolegal autopsy. The subjects were divided into 3 subgroups according to the medical history: (1) epilepsy, (2) psychiatric disorders, and (3) no specific medical history...

BACKGROUND: First Nations, Inuit, and Métis are at higher risk of adverse birth outcomes than are non-Indigenous people. However, relatively little perinatal information is available at the national level for Indigenous people overall or for specific identity groups. DATA AND METHODS: This analysis describes and compares rates of preterm birth, small-for-gestational-age birth, large-for-gestational-age birth, stillbirth, and infant mortality (neonatal, postneonatal, and cause-specific) in a nationally representative sample of First Nations, Inuit, Métis, and non-Indigenous births...

BACKGROUND: The incidence of plagiocephaly has increased in the 25 years since the "Back to Sleep" campaign in 1991 to prevent sudden infant death. Plagiocephaly is not considered to be a pathological condition. It is more of an esthetic impairment and could have potentially negative psychological or psychosocial consequences; therefore, treatment is recommended. The aim of this study is to compare conventional anthropometry and laser scanning - two different measurement methods - as diagnostic instruments for plagiocephaly...

RATIONALE: High take-off of the coronary arteries is a rare cardiac anatomic anomaly, which may occur independently or with other congenital heart defects. In the clinical setting, it is noteworthy as a cause of sudden cardiac death. Further, it is vital to identify such anomalies to avoid intraoperative catastrophes in surgeries for congenital heart defects. PATIENT CONCERNS: A II/6 systolic heart murmur on physical examination was incidentally found in a 9-year-old boy; he was confirmed to have a secundum-type atrial septal defect on echocardiography...

Sudden death is defined as unexpected cardiac arrest occurring less than one hour after the onset of the first symptoms. Between 2010 and 2012, 23 maternal deaths were considered as unexplained sudden deaths and three of them were not evaluated due to a lack of clinical data. In addition, 13 maternal deaths with an identified cause occurred in a clinical context of sudden death (7 cases of pulmonary embolism, 2 cases of epilepsy, and 2 cases of cardiomyopathy). The first maneuvers of resuscitation in the presence of bystanders were attempted in 8 of 22 cases (36%)...

Cardiac disease is a common clinical manifestation present in a variety of neuromuscular disorders, most notably the muscular dystrophies. Heart disease may produce the presenting or predominant symptoms in these disorders but more often does not result in clinical features at the time of initial presentation. Cardiac involvement in the muscular dystrophies results from pathologic changes in the myocardium and the cardiac conduction system, leading to cardiomyopathy and/or rhythm disturbances including supraventricular arrhythmias, life-threatening ventricular arrhythmias, and sudden cardiac death...

Cerebral malaria is a complex, acute, neurological disease characterised by a sudden onset of cerebral symptoms. This disease is manifested as initial arousable stage that is followed by an unarousable coma and eventually death. Parasite burden and CD8+ T cell count in the brain determines the disease outcome. Cytotoxic CD8+ T cell-derived Granzyme-b is required for the development of experimental cerebral malaria (ECM), but the mechanism of pathogenesis is not known. Here, we show that CD8+ T cells infiltrate in to the brain during ECM releasing Granzyme-b that is cytotoxic to neuronal cells...
