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.
