Introduction: The AHA/ACC framework of valvular heart disease (VHD) stages emphasizes the progressive nature of VHD. Limited data exist regarding the association of VHD stages with prognostic cardiac biomarkers of myocardial stress (NT-proBNP) and injury (high sensitivity troponin-T [hs-TnT]). Methods: Among 6,078 participants in the community-based Atherosclerosis Risk in Communities (ARIC) who underwent echocardiography at the 5 th study visit (2011-2013) and were free of prior valve replacement, we classified VHD stages based on quantitative and qualitative assessments of mitral and aortic valve stenosis and regurgitation. Multivariable linear regression models were used to relate VHD stages to concentrations of NT-proBNP and hs-TnT at Visit 5. Biomarker values were log-transformed. Models were adjusted for age, sex, race, hypertension, diabetes, heart failure, prior myocardial infarction, body mass index, atrial fibrillation, study center, and systolic blood pressure at Visit 5. Results: The mean age was 76±5, 58% were women, 22% were Black. Stage A VHD was present in 2,362 participants (39%), Stage B in 1011 (17%), and Stage C or D in 65 (1%). In multivariable models, higher VHD stage was associated with a graded increase in NT-proBNP and hs-TnT concentrations (Figure) . Compared to participants free of VHD, even Stage A (‘at risk’) participants demonstrated higher concentrations of both NT-proBNP (p Conclusion: Worse VHD stages, even in the absence of severe stenosis or regurgitation, are associated with higher concentrations of markers of myocardial stress (NT-proBNP) and injury (hs-TnT) independent of traditional cardiovascular risk factors.
