Valsartan Improves Arterial Stiffness in Type 2 Diabetes Independently of Blood Pressure Lowering
Increased arterial stiffness , as estimated from aortic pulse wave velocity ( Ao-PWV ) , and albuminuria are independent predictors for cardiovascular disease in type 2 diabetes mellitus ( T2DM ) . Whether angiotensin receptor blockers ( ARBs ) , drugs with cardio-renal protective effects , improve Ao-PWV to a greater extent than other equipotent antihypertensive medications remains unclear . After a 4-week washout phase , we compared the effects of valsartan ( n=66 ) , an ARB , with that of amlodipine ( n=65 ) , a calcium channel blocker on Ao-PWV in 131 T2DM patients with pulse pressure ( PP ) ≥60 mm Hg and raised albumin excretion rate ( AER ) in a 24-week r and omized , double-blind , parallel group study . Hydrochlorothiazide ( HCTZ ) 25 mg/d was added to valsartan 160 mg and amlodipine 5 mg/od uptitrated to 10 mg/od after 4 weeks to ensure equivalent BP control . After 24 weeks brachial and central aortic PP had fallen to a similar extent with attained mean ( SD ) brachial and central PP of 61.6 ( 13.6 ) and 47.3 ( 14.1 ) mm Hg in the valsartan/HCTZ group and 61.5 ( 12.2 ) and 47.3 ( 9.9 ) mm Hg in the amlodipine group , respectively . Ao-PWV showed a significantly greater reduction , mean ( 95 % CI ) , −0.9 m/s ( −1.4 to −0.3 ) for valsartan/HCTZ compared to amlodipine ( P=0.002 ) . AER fell significantly only with Val/HCTZ from 30.8(20.4 , 46.5 ) to 18.2(12.5 , 26.3 ) mcg/min , ( P=0.01 ) with between treatment difference in favor of Val/HCTZ of −15.3mcg/min ( P<0.001 ) . Changes in AER and Ao-PWV were not correlated . Valsartan/HCTZ improves arterial stiffness and AER to a significantly greater extent than amlodipine despite similar central and brachial BP control . These 2 effects , which appear independent of each other , may explain the specific cardio-renal protective properties of ARBs
