Genes switch on and off can influence serious heart conditions

The scientists from the Gladstone Institute in San Francisco focused on two genes, and their role in cardiomyopathy, a enlarging and weakening of the heart muscle which is a feature in life-threatening heart defects in children and adults

A new Nature Genetics report says that scientists may be closer to understanding how genes can influence serious heart conditions. The failure to turn off a specific gene at the right time in an embryo’s development could mean illness later in life. Mice in which the gene was left active were born apparently healthy, but suffered heart muscle problems later. A heart charity said it might on…

Extreme exercise may permanently damage the heart and trigger rhythm abnormalities

Researchers warn that extreme exercise, such as marathons, may permanently damage the heart and trigger rhythm abnormalities. They say the safe “upper limit” for heart health is a maximum of an hour a day – after which there is little benefit to the individual. A review of research evidence by US physicians says intensive training schedules and extreme endurance competitions can cause long-…
