A recent study conducted by Amsterdam UMC indicates that the Apple Watch could significantly enhance the detection of atrial fibrillation (AFib) among older adults. The six-month research involved 437 participants aged over 65, all at higher risk for strokes. Of these, 219 individuals utilized the smartwatch for approximately 12 hours daily, while the remaining 218 received conventional care.
Results showed that 21 participants from the smartwatch group were diagnosed with AFib, with 57% of those exhibiting no prior symptoms. In contrast, only 5 individuals from the standard-care group were diagnosed, all of whom had noticeable symptoms. This suggests that the continuous monitoring capabilities of the Apple Watch are crucial for identifying AFib in asymptomatic individuals.
According to cardiologist Michiel Winter, the integration of PPG and ECG functions in smartwatches can help healthcare professionals diagnose arrhythmias in patients who may otherwise remain unaware of their condition. The findings imply a potential decrease in stroke risk, which could ultimately lead to lower healthcare costs, potentially balancing the initial investment in the device.
