Study identifies new gene variations associated with heart rate

Through a collaborative genome-wide study on individuals, researchers have discovered 14 new genetic variations that are associated with heart rate. Since heart rate is a marker of cardiovascular health, these findings could ...

New stroke gene discovery could lead to tailored treatments

An international study led by King's College London has identified a new genetic variant associated with stroke. By exploring the genetic variants linked with blood clotting – a process that can lead to a stroke – scientists ...

Stem-cell approach shows promise for Duchenne muscular dystrophy

Researchers have shown that transplanting stem cells derived from normal mouse blood vessels into the hearts of mice that model the pathology associated with Duchenne muscular dystrophy (DMD) prevents the decrease in heart ...

Research links circadian rhythms to sudden cardiac death

A fundamental discovery reported in the March 1st issue of the journal Nature, uncovers the first molecular evidence linking the body's natural circadian rhythms to sudden cardiac death (SCD). Ventricular arrhythmias, or ...

Genetic mutation implicated in 'broken' heart

For decades, researchers have sought a genetic explanation for idiopathic dilated cardiomyopathy (DCM), a weakening and enlargement of the heart that puts an estimated 1.6 million Americans at risk of heart failure each year. ...

Brain and heart link may explain sudden death in Rett

Poets might scoff at the notion that heart and brain are closely related, but scientists led by those at Baylor College of Medicine (www.bcm.edu) say a genetic defect that affects the brain can stop a heart.

Genetics

Biologists use flies, mice to study Down syndrome

A novel study involving fruit flies and mice has allowed biologists to identify two critical genes responsible for congenital heart defects in individuals with Down syndrome, a major cause of infant mortality and death in ...

No heart attack risk from attention-deficit drugs: study

A major study of more than one million children and young adults has shown no higher risk of heart attack among those who take drugs for attention deficit hyperactivity disorder, a US study said Tuesday.
