We planned a randomized, double blind clinical trial to evaluate whether an antihypertensive intervention at the proximal or distal level of the renin-angiotensin-aldosterone system could have different effects on a broad range of innovative cardiovascular risk biomarkers. A total of 288 hypertensive Caucasian patients (115 men and 113 women), aged >= 18 years, were enrolled in this study. They were randomized to take losartan 50 mg per day or ramipril 5 mg per day for 1 month and titrated up to 100 mg per day and 10 mg per day for 13 months, respectively. At baseline, 1, 2 and 14 months after therapy initiation, we evaluated the following parameters: body weight, body mass index (BMI), systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting plasma glucose (FPG), M-value, adiponectin (ADN), resistin (r), retinol binding protein-4 (RBP-4), visfatin, vaspin, high-sensitivity C-reactive protein (Hs-CRP), matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9). No variation of body weight, BMI, FPG or vaspin was obtained with either treatment. We recorded a similar improvement in SBP, DBP and Hs-CRP with both treatments; however, losartan also increased M-value, ADN and visfatin, whereas ramipril did not. Furthermore, losartan decreased r, RBP-4, MMP-2 and MMP-9, whereas ramipril did not have any effect on these parameters. In conclusion, we observed that short-term treatment with losartan improved several metabolic parameters (M-value, ADN, RBP-4, r and visfatin) and decreased vascular remodeling biomarkers (MMP-2 and MMP-9) in hypertensive subjects, whereas ramipril did not.
