Circulation: Cardiovascular Quality and Outcomes

RESULTS: At visit 1, 413 (32%) individuals were classified as Stage A and 413 (32%) as Stage B. By visit 2, 146 (35%) individuals from Stage A progressed with the vast majority (n=142) progressing to Stage B. In comparison, a total of 23 (6%) individuals progressed from Stage B. A greater rate of progression was seen for Stage A compared with Stage B (8.7 per 100 person-years [95% CI, 7.4–10.2] versus 1.4 per 100 personyears [95% CI, 0.9–2.1]; P<0.001). NT-proBNP correlated with progression for Stage B (P=0.01), but not for Stage A (P=0.39). A multivariate model found female sex (odds ratio, 1.65 [95% CI, 1.05–2.58]; P=0.03), increased E/e’ (odds ratio, 1.13 [95% CI, 1.02–1.26], P=0.02), and beta blocker use (odds ratio, 2.19 [95% CI, 1.25–3.82], P=0.006) were associated with progression for Stage A. There was a signal that cardiovascular mortality was higher in individuals who progressed, although not statistically significant (P=0.06 for Stage A and P=0.05 for Stage B).
