Proposed elements for inclusion in a unifying clinical classification scheme for AF. Elements with established or potential roles in guiding management of patients with AF are displayed. Examples of metrics that measure these elements are shown, along with potential management decisions that might depend on the degree of severity on each scale. Elements and decisions might be inter-related. Arrows indicate a proposed sequential flow of assessments. Abbreviations: AF, atrial fibrillation; AV, atrial-ventricular; CCF–SAF, Canadian Cardiovascular Society Severity of Atrial Fibrillation; CHADS2, where “C” denotes congestive heart failure, “H” denotes hypertension, “A” denotes age > 75 years, “D” denotes diabetes mellitus, and “S” denotes stroke or transient ischemic attack; SF-36, 36-item short-form survey for health and quality of life.
