Vigorous exercise does not increase long QTS-associated cardiac event rate
The data could help inform decision making on participating in vigorous exercise, authors say.
In patients with congenital long-QT syndrome, the rate of cardiac events associated with long-QT syndrome was low and did not differ between those exercising vigorously or non-vigorously, according to a US study.
Researchers from the Yale School of Medicine in New Haven, Connecticut enrolled individuals aged 8-60 with phenotypic or genotypic long-QT syndrome (LQTS).
They were from 37 sites in five countries in the US National Institutes of Health-funded LIVE-LQTS study.
Participants or parents answered questions about physical activity and clinic event surveys every six months for three years to examine whether vigorous exercise increases the risk for ventricular arrhythmias.
