US researchers on Monday announced a new wearable, long-term continuous heart monitor that is likely to identify more cases of irregular heart rhythm -- also known as atrial fibrillation linked to the risk of stroke and heart failure -- compared to usual care.
However, the heart monitors did not lead to a reduction in hospitalisations due to stroke, said the team at the Duke Clinical Research Institute in North Carolina, US.
“Atrial fibrillation is often undiagnosed and can increase the risk of ischemic stroke, which is largely reversible by oral anticoagulation,” said lead author Renato Lopes, Professor of Medicine at the Institute.
“We still need definitive evidence that diagnosis of atrial fibrillation through systematic screening can lead to subsequent treatment with oral anticoagulation and therefore, lower stroke risk,” Lopes said.
