21/07/2017 Aim  Is obesity-related AF a problem in the Midland region?  Does the AF burden (reflected by demand on clinical services) differ between obese and non-obese patients? Methods Our patient cohort:  Waikato DHB facilities  1 July 2013 – 31 March 2016  Discharge code ‘AF’ from ED or Cardiology  Echocardiogram within 6 months BMI ≥ 27 = Group 1 BMI < 27 = Group 2 3

21/07/2017 Results Patients with AF 39% 61% Group 1 (BMI >=27) Group 2 (BMI <27) 4
