Background: Risk of atrial fibrillation (AF) in masked and white coat uncontrolled hypertension (MUCH and WUCH, respectively) has not yet been investigated. We assessed the risk of new-onset AF in MUCH and WUCH detected by ambulatory blood pressure (BP) monitoring.
Methods: The occurrence of AF was evaluated in 2,135 treated hypertensive patients aged >40 years, with baseline sinus rhythm, by electrocardiogram.
