There were 1545 participants (5.3%) with a reduced eGFR (50–59.9 ml/min/1.73 m2: n = 1416, 45–49.9 ml/min/1.73 m2: n = 118, < 45 ml/min/1.73 m2: n = 11). The reduced eGFR group was associated with an older

age and higher risk Adriamycin cell line profile of traditional cardiovascular risk factors. During a mean follow-up period of 9.3 years (271,383 person-years), 43.9% of the cohort (12,818 participants) developed hypertension. The number of incident hypertension cases determined by the use of antihypertensive drugs was 2.2% (292 participants) of all incident hypertension cases. The cumulative incidence of hypertension was higher in the positive proteinuria group than in the negative proteinuria group in a Kaplan–Meier analysis (negative: 43.6%; trace: 54.2%; ≥ 1 +: 61.0% in 10 years; log-rank test, p < 0.001) (Fig. 1A). www.selleckchem.com/products/PF-2341066.html Similarly, the cumulative incidence of hypertension was higher in the reduced eGFR group than

in the preserved eGFR group (≥ 60 ml/min/1.73 m2: 43.4%; 50–59.9 ml/min/1.73 m2: 52.9%; < 50 ml/min/1.73 m2: 62.8% in 10 years; log-rank test, p < 0.001) (Fig. 1B). The median duration since test of proteinuria/reduced eGFR was 5 (2–10) years, and that of reduced eGFR 5 (2–10) years. The association between the two positive proteinuria categories (trace and ≥ 1 +) and incident hypertension remained significant even after adjusting for age (Table 2). Further adjustment for other potential confounders attenuated the associations; however, the association for proteinuria ≥ 1 + remained significant, even in model 5, which second included eGFR (adjusted HR 1.19 [95% CI, 1.06 to 1.34], p < 0.001). Notably, when we compared positive vs. negative proteinuria, the adjusted HR was statistically significant, even in model 5 (1.14 [95% CI, 1.03 to 1.26], p < 0.001). On the other hand, the association between a reduced eGFR (≥ 60 ml/min/1.73 m2) and incident hypertension was more substantially attenuated by the adjustment for age. However, a significant association was observed for an eGFR of < 50 ml/min/1.73 m2 only

(vs. ≥ 60 ml/min/1.73 m2) after further adjustment (1.29 [95% CI, 1.03 to 1.61] in model 5, p < 0.001). We did not observe any significant associations between a reduced eGFR (< 60 ml/min/1.73 m2) and incident hypertension in models 3–5 (HR 1.02 [0.95–1.10] in model 3). We further evaluated the association between positive proteinuria (vs. negative proteinuria) and incident hypertension in several subgroup analyses divided by the following parameters: baseline BP, age, BMI, diabetes mellitus, dyslipidemia, current smoking and current alcohol intake. Positive associations between positive proteinuria and incident hypertension were observed in several of the subgroups tested, with few significant interactions. Of importance, the HR was significant among individuals with an optimal BP at baseline (< 120/80 mm Hg) (adjusted HR 1.31 [95% CI, 1.10 to 1.
