Flow chart for categorizing antithrombotic guideline adherence, amongst patients with follow-up. *In high-risk patients without CAD and diabetes. AP, antiplatelet agent. All patients with follow-up: pink = over-treatment (n = 574); light green = guideline adherent (n = 1602); grey = undertreatment (n = 458). For high-risk patients only: pink = over-treatment (n = 514); light green = guideline adherent (n = 1513); grey = undertreatment (n = 433). Amongst ‘low risk’ if scheduled for cardioversion, these are re-categorized as high risk. Also, any patients with recent ACS or stents would be re-categorized as ‘high risk’ and ‘guideline adherent’ (light green).
