Why the study?
Does adding QTc interval duration to a conventional risk model improve the prediction of cardiovascular death in a primary care population?
Does adding QTc interval duration to a conventional risk model improve the prediction of cardiovascular death in a primary care population?
Incorporating QTc interval duration into conventional risk models improves the accuracy of long-term cardiovascular death prediction in primary care settings.
Supports QTc exploration in primary care risk models; hypothesis-generating and should not yet change practice.
Important differences were observed across subgroups when the absolute long-term risk of CVD was estimated based on QTc interval duration. The accuracy of the personalized CVD prognosis can be improved when the QTc interval is introduced to a conventional risk model for CVD.
