Management of chronic kidney disease (CKD) patients includes efforts directed toward modifying traditional cardiovascular risk factors. Such efforts include optimal management of hypertension together with the initiation of statin therapy. >bold<>italic<Methods:>/italic<>/bold< In this observational study, we determine the modifying effect of statins on the relationship of systolic blood pressure (SBP) goal with mortality and other outcomes in patients with CKD participating in a clinical trial. At baseline, 2,646 CKD patients (estimated glomerular filtration rate < 60 mL/min/1.73 m>sup<2>/sup<) were randomized to an intensive SBP goal < 120 mm Hg or standard SBP goal <140 mm Hg. One thousand two hundred and seventy-three were not on statin, 1,354 were on a statin, and in 19 the use of statin was unknown. The 2 primary outcomes were all-cause mortality and cardiovascular disease (CVD) mortality. >bold<>italic<Results:>/italic<>/bold< The relationships of SBP goal with all-cause mortality (interaction >italic
/italic< = 0.009) and cardiovascular (CV) mortality (interaction >italic
/italic< = 0.021) were modified by the use of statin after adjusting for age, gender, race, CVD history, smoking, aspirin use, and blood pressure at baseline. In the statin group, targeting SBP to < 120 mm Hg compared to SBP < 140 mm Hg significantly reduced the risk of all-cause mortality (adjusted hazard ratio [aHR] 0.44 [0.28-0.71]; event rates 1.16 vs. 2.5 per 100 patient-years) and CV mortality (aHR 0.29 [0.12-0.74]; event rates 0.28 vs. 0.92 per 100 patient-years) after a median follow-up of 3.26 years. In the non-statin group, the risk of all-cause mortality (aHR 1.07 [0.69-1.66]; event rates 2.01 vs. 1.94 per 100 patient-years) and CV mortality (aHR 1.42 [0.56-3.59]; event rates 0.52 vs. 0.41 per 100 patient-years) were not significantly different in both SBP goal arms. >bold<>italic<Conclusion:>/italic<>/bold< The combination of statin therapy and intensive SBP management leads to improved survival in hypertensive patients with CKD.
