Sudden cardiac death is a tragic event that strikes all age groups and is unfortunately increasing in prevalence. Because it is difficult to predict those at highest risk, this study is designed to test the hypothesis that new imaging techniques (magnetic resonance imaging [MRI] and computed tomography [CT]) are useful for identifying factors which put people at high risk for sudden death.

Sudden death is a major problem in industrially developed countries. Despite a decline in ischemic heart disease mortality and the progress has been made in resuscitation, treatment of sud...
To evaluate whether sequence variants and selected cardiac ion channel genes are associated with risk of sudden cardiac death in the general population.
Sudden cardiac arrest (SCA) is a sudden, unexpected loss of heart function. It is a leading cause of death, and more than 400,000 people in the United States die each year as a result of S...
The purpose of the study is to better identify hereditary cardiac causes of sudden unexpected death in young subjects through Next-Generation Sequencing of autopsy tissue
Sudden cardiac death due to arrhythmia is the leading cause of death in end-stage renal disease (ESRD) patients treated with hemodialysis (HD). As it is anticipated that the number of indi...
Background Reports on the incidence and causes of sudden cardiac death among young athletes have relied largely on estimated rates of participation and varied methods of reporting. We sought to invest...
Although few doubts remain that physical exercise should be widely promoted for maintenance of health and fitness, the risk of adverse events such as sudden death (especially due to cardiac causes, i....
Recent lines of evidence suggest that, as in other countries, sudden cardiac death (SCD) is more common in the Japanese dialysis clinical setting than we previously thought.
Hypertrophic cardiomyopathy (HCM) is a heart disease characterized by hypertrophy of the left ventricular myocardium and is most often caused by mutations in sarcomere genes. The structural and functi...
Cardiovascular disease is the leading cause of sudden death in the world. The etiology of sudden cardiac death involves a wide range of diseases, but seldom pericardial cysts. A pericardial cyst is an...
Unexpected rapid natural death due to cardiovascular collapse within one hour of initial symptoms. It is usually caused by the worsening of existing heart diseases. The sudden onset of symptoms, such as CHEST PAIN and CARDIAC ARRHYTHMIAS, particularly VENTRICULAR TACHYCARDIA, can lead to the loss of consciousness and cardiac arrest followed by biological death. (from Braunwald's Heart Disease: A Textbook of Cardiovascular Medicine, 7th ed., 2005)
Inflammatory processes of the muscular walls of the heart (MYOCARDIUM) which result in injury to the cardiac muscle cells (MYOCYTES, CARDIAC). Manifestations range from subclinical to sudden death (DEATH, SUDDEN). Myocarditis in association with cardiac dysfunction is classified as inflammatory CARDIOMYOPATHY usually caused by INFECTION, autoimmune diseases, or responses to toxic substances. Myocarditis is also a common cause of DILATED CARDIOMYOPATHY and other cardiomyopathies.
A sudden CARDIAC ARRHYTHMIA (e.g., VENTRICULAR FIBRILLATION) caused by a blunt, non-penetrating impact to the precordial region of chest wall. Commotio cordis often results in sudden death without prompt cardiopulmonary defibrillation.
Autosomal dominant syndrome characterized by cardiac and cutaneous MYXOMAS; LENTIGINOSIS (spotty pigmentation of the skin), and endocrinopathy and its associated endocrine tumors. The cardiac myxomas may lead to SUDDEN CARDIAC DEATH and other complications in Carney complex patients. The gene coding for the PRKAR1A protein is one of the causative genetic loci (type 1). A second locus is at chromosome 2p16 (type 2).
An autosomal dominant defect of cardiac conduction that is characterized by an abnormal ST-segment in leads V1-V3 on the ELECTROCARDIOGRAM resembling a right BUNDLE-BRANCH BLOCK; high risk of VENTRICULAR TACHYCARDIA; or VENTRICULAR FIBRILLATION; SYNCOPAL EPISODE; and possible sudden death. This syndrome is linked to mutations of gene encoding the cardiac SODIUM CHANNEL alpha subunit.
Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
