초록
Background: The value of metabolic syndrome (MetS) evaluation in predicting cardiovascular disease is recently criticized. We investigated, in hypertensive patients without diabetes mellitus, the influence of MetS on the target organ damage. Methods: Data from the fourth Korean National Health and Nutrition Examination Survey performed in 2008 were analyzed. Metabolic syndrome is defined by the 2001 National Cholesterol Education Program-Third Adult Treatment Panel guideline. The category of hypertension is defined following the seventh report of the Joint National Commitee-7 guideline. Results:The prevalence of target organ damage (TOD), defined as history of myocardial infarction/angina/stroke/chronic renal disease as well as the presence of macroalbuminuria, was increased according to blood pressure; 8.5% in the population of normal blood pressure, 12.5% in those of prehypertensive range, and 20.5% in hypertensive population. Hypertensive population associated with MetS showed greater prevalence of TOD than those without MetS even excluding diabetic population. The presence of MetS in hypertensive population showed 2.2 fold increased risk for TOD. Any single parameter of MetS diagnostic criteria as well as obesity did not show the comparable range of risk prediction as MetS. Conclusions:These results indicate a strong relationship of Mets with TOD in hypertensive population. Evaluating the metabolic components in hypertensive population is necessary in establishing management strategies for overall risk.
