Pulse pressure is an important risk factor in the development of atrial fibrillation, a study has shown.

According to the US community research involving 5,331 heart patients aged over 35, 23.3% of patients with pulse pressure above 61mmHg developed atrial fibrillation after a 20-year follow-up period.

Among those with pulse pressures of 40mmHg or less, incidence of atrial fibrillation was 5.6%. Overall, the risk of atrial fibrillation increases by 26% per 20-mm Hg increment.
