Sudden Cardiac Death News and Research

RSS

The term sudden cardiac death refers to natural death from cardiac causes, heralded by abrupt loss of consciousness within one hour of the onset of acute symptoms.

Novel dual approach can be a promising way to enhance cardiac repair

As a medical emergency caused by severe cardiovascular diseases, myocardial infarction (MI) can inflict permanent and life-threatening damage to the heart.

Three signs of real progress against sickle cell disease

A decade ago, the United Nations declared June 19 to be World Sickle Cell Awareness Day- and for good reason.

Study reveals how genetic message to produce healthy heart tissue is altered during stress, aging

Researchers at the Fralin Biomedical Research Institute at Virginia Tech Carilion have revealed how a genetic message to produce healthy heart tissue is altered in the body during stress and aging to contribute to sudden cardiac death.

Using blood thinners in heart failure patients associated with reduced risk of thromboembolic events

Researchers at University of California San Diego School of Medicine found that using blood thinners in patients with worsening heart failure, coronary artery disease or irregular heart rhythms was associated with a 17 percent reduced risk of thromboembolic events, such as stroke and heart attack.

EuroCMR 2019 to present novel studies on clinical use of cardiovascular magnetic resonance

Novel studies from around the world showing cutting-edge clinical use of cardiovascular magnetic resonance will be presented at EuroCMR 2019, a meeting of the European Association of Cardiovascular Imaging, a branch of the European Society of Cardiology.

Potential drug targets cause of adult-onset muscular dystrophy

People diagnosed with myotonic dystrophy type 1 have difficulty unclenching muscles due to a genetic defect that generates toxic material within their cells.

New computer program predicts risk of life-threatening arrhythmias

Combining a wealth of information derived from previous studies with data from more than 500 patients, an international team led by researchers from Johns Hopkins has developed a computer-based set of rules that more accurately predicts when patients with a rare heart condition might benefit--or not--from lifesaving implanted defibrillators.

New study examines smarter automatic defibrillator

Thousands of patients with congestive heart failure benefit from automatic implantable cardiac defibrillators that deliver shocks to the heart to correct abnormal heart rhythms. These defibrillators improve survival in patients who are at risk for sudden cardiac death.

Research: Pure omega-3 prescription drug significantly reduces the occurrence of ischemic events

Taking a high dose of icosapent ethyl--a pure and stable prescription form of the omega-3 fatty acid known as EPA--significantly reduces the occurrence of first, subsequent and total ischemic events, including heart attacks, strokes and related deaths, among people at high cardiovascular risk despite already being on statin therapy, according to research presented at the American College of Cardiology's 68th Annual Scientific Session.

Preventative cardioverter defibrillator implantation is of little benefit to kidney dialysis patients

Placing an implantable cardioverter defibrillator in kidney dialysis patients as a preventative measure is of little benefit.

Athletes with sleep disordered breathing may be at risk of heart abnormalities, suggests study

A study of university rugby players has shown that they are more likely to suffer sleep-disordered breathing than an average middle-aged man.

How many push-ups can you do? Men who are able to do ten push-ups are less likely to have a stroke

The findings show that middle-aged men who are able to complete 10 push-ups could reduce their risk of heart attack and stroke by as much as 97 percent.

Research finds reasons for sudden cardiac death in patients with stable ischemic disease

Sudden death in patients with stable ischemic heart disease is not a common occurrence and is sparsely reported.

Higher risk of cardiac death in African Americans linked to income and educational disparities

African Americans - especially African American women - have a significantly higher risk of sudden cardiac death during their lifetime than whites, and much of the disparity can be attributed to income and education levels, according to new research in the American Heart Association's journal Circulation.

RNA-binding protein needed for development of pathological hypertrophy

In response to conditions such as high blood pressure and reduced blood flow to cardiac muscle, the adult heart can drastically enlarge, a process called pathological hypertrophy that preserves cardiac function in the short term but predisposes patients to intractable heart failure and sudden cardiac death if left untreated.

SPECT imaging combined with cardiac MRI could help improve ventricular tachycardia ablation

Adding functional imaging to structural imaging of patients with ventricular tachycardia (VT) has the potential to improve current VT ablation strategies, according to new research published in the January issue of The Journal of Nuclear Medicine.

Researchers investigate how physical exercise protects against sudden cardiac death

A group of researchers from the departments of Physical Therapy, Medicine and Electronic Engineering of Valencia University and from the innovations group ITACA have just published research into physical exercise as a protector against sudden cardiac death. The study has been published in the 'PlosOne' journal.

Commonly prescribed ADHD drug unlikely to increase cardiovascular risks in children

With more than 1.8 million children in the U.S. being treated annually with drugs for attention deficit hyperactivity disorder, the possibility that such drugs could damage their hearts has been a significant cause of concern for parents and physicians alike.
