What are the two types of EHRA categorization in relation to the type of OAC used in patients with AF?
The two types of EHRA categorization in relation to the type of OAC used in patients with AF are EHRA Type 1 and EHRA Type 2. EHRA Type 1 is used for patients with valvular heart disease (VHD) who need therapy with a vitamin K antagonist (VKA). This includes those with mitral stenosis of rheumatic origin and mechanical prosthetic valve replacements. EHRA Type 2 is used for patients with VHD who need therapy with a VKA or non-vitamin K antagonist oral anticoagulants (NOACs), taking into consideration CHA2DS2-VASc score risk factor components. This includes those with mitral regurgitation, mitral valve repair, aortic stenosis, aortic regurgitation, tricuspid regurgitation, tricuspid stenosis, pulmonary regurgitation, pulmonary stenosis, bioprosthetic valve replacements, and trans-aortic valve interventions.
