MR proANP and NT proBNP levels were significantly higher in the AF group compared with the SR group (385 (258\u2013598) versus 201 (89\u2013375)\u2005pmol\/l for MR proANP, p&lt;0.001 and 4916 (2169\u201310285) versus 1177 (258\u20135166)\u2005pg\/ml, p&lt;0.001 for NT proBNP). Diagnostic accuracy in AF patients was similar for MR proANP (0.90, 95% CI 0.84 to 0.95) and NT proBNP (0.89, 95% CI 0.81 to 0.96). Optimal cut-off levels in AF patients were significantly higher compared with the optimal cut-off levels for patients in SR (MR proANP 240 vs 200\u2005pmol\/l; NT proBNP 2670 vs 1500\u2005pg\/ml respectively). After adjustment in multivariable Cox proportional hazard analysis, MR proANP strongly predicted one-year all-cause mortality (HR=1.13 (1.09\u20131.17), per 100\u2005pmol\/l increase, p&lt;0.001).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>In AF patients, NT proBNP and MR proANP have similar diagnostic value for the diagnosis of AHF.
