Evaluation of N-terminal pro-B-type natriuretic peptide and high-sensitivity C-reactive protein relationship with features of metabolic syndrome in high-risk subgroups for cardiovascular disease.

Aim: This study evaluating N-terminal pro-B-type natriuretic peptide (NT-pro-BNP) and high-sensitivity C-reactive protein (hs-CRP) relationship with features of the metabolic syndrome (MS) in high risk subgroups for cardiovascular disease (CVD) in Trinidad. Materials and Methods: The sample population consisted of 160 subjects, 78 of whom were African and 82 East Indian attending medical outpatient clinics of regional health authority hospitals of Trinidad. Results: Systolic blood pressure, triglycerides, glucose and insulin as well as NT-pro-BNP were elevated among the East Indian sub-population, with only systolic blood pressure being significantly elevated among the African sub-population. NT-pro-BNP and hs-CRP demonstrated significant correlations with respect to the majority of independent risk factors inclusive of Adult Treatment Panel III and American Association of Clinical Endocrinologists defined criteria for MS. NT-pro-BNP demonstrated stronger association among the East Indian sub-population as compared to that of the African sub-population. Conclusions: Our study showed that the East Indian subgroup was more at risk for CVD as evidenced by the fulfillment of the criteria for diagnosis of MS and therefore NT-pro-BNP and hs-CRP can be deemed a suitable marker for MS.
