Know how heart responds to exercise

WASHINGTON D.C: New genes have been found that can determine how the heart responds to exercise, a new research has claimed.

According to a study led by the Queen Mary University of London, 30 new gene locations have been discovered that determine how the heart responds to and recovers from exercise.

The study was conducted using the genetic and electrocardiogram data of 67,000 people from UK Biobank.

The findings could be used to improve the identification of people with impaired heart rate during recovery and those at higher risk of heart disease mortality.

The difference in heart rate response to exercise was as much as 3.15 beats per minute, depending on the genetic risk score of an individual, while the difference in heart rate response to recovery differed by as much as 10.4 beats per minute.

Lead researcher Patricia Munroe said, "Our findings advance our knowledge on key pathways controlling heart rate response to exercise and recovery, information which may be valuable in the future for cardiovascular risk prediction."

Co-lead researcher Pier Lambiase said, "This first study by our 'Electrogenomics' group is a wonderful example of the power of the collaboration between UCL Electrophysiology & QMUL Genomics, opening new avenues to dissect the mechanistic links between heart control and cardiovascular outcomes."

The results have implications to target new therapies to treat abnormal heart rhythms and potentially increase heart health.

The study appears in the journal Nature Communications.
