BACKGROUND: It is widely accepted that hypertension is a pro-inflammatory disease and that the immune system plays a vital role in mediating hypertensive outcomes, end organ damages . and modulation of hypertensive pathology [2]. Patient with MetS usually present increased levels of C-reaktive protein (CRP) wich is a prototypic marker of inflammation [5], however the data of the influence of incresed levels of CRP on the control of the aterial hypertension in patients with MetS, are scarce. OBJECTIVE: We sought to determine the incresed CRP levels influence on the control of the aterial hypertension in patients with MetS. METHODS: We conducted a multicenter observational cross-sectional study. The study population recruited from a coule of outpatient clinic between june 2018 and june 2019. The population study consisted of 420 patients with MetS aged ≥ 18 years, divided in two groups:211 with level of CRP>3mg/l , and 209 participans with CRP level <3mg/l. RESULTS: Among those with CRP level > 3mg/l(N=211) controlled BP according to evidence and current guidelines, was achieved in 23.6% of participans, whereas among those with CRP level <3mg/l(N=209) controlled BP was achived in 48.3%; p=0.000). There was independent association of CRP levels >3mg/l with uncontrolled BP (OR=3.1, 95%CI 2.06 - 4.75). There were signifiacant association of uncontrolled BP with: uncontrolled glycemia (OR =1.4,95%CI 0.97-1.84); increased BMI (OR=4.4; 95%CI 3.02-4.05) and five risk factors for MetS.(OR=2.3, 95%CI 1.93-2.81). CONCLUSIONS: We think,we brought some good evidence,in our present study ,that patients with MetS and higher CRP level have a higher prevalence of unconrolled BP.
