PARAGANO, Antonio J. et al. Prevalence and Association of Hypertension with the Different Components of the Metabolic Syndrome. Rev. argent. cardiol. [online]. 2009, vol.77, n.4, pp.274-279. ISSN 1850-3748.

Background Hypertension coexists with other cardiovascular risk factors, especially obesity and dyslipemia; this association increases the risk particularly in patients with established heart disease. For this reason, the identification and control of these factors is essential for the global management of hypertensive patients. Objectives To assess the prevalence of hypertension and its association with the different components of the metabolic syndrome. Material and Methods We included 975 subjects (37±9 years, 62% were men) without demonstrable heart disease. Metabolic syndrome variables were those defined by the ATP III-IDF according to gender: waist circumference ³102/88 cm, LDL-cholesterol level £40/50 mg/dl, glucose blood level and triglycerides ³150 mg/dl. Subjects were grouped by gender and classified as hypertensive (JNC 7), with blood pressure ³140/90 mm Hg, non hypertensive and controls. The frequency of each variable of the metabolic syndrome was established in hypertensive subjects and the prevalence of hypertension was determined for each variable. Results There were 114 hypertensive men that were compared to 495 controls: age: 42±10 versus 36±9 years, waist circumference ³102 cm: 31% versus 15%, triglycerides ³150 mg/dl: 33% versus 20%, glycemia ³100 mg/dl: 30% versus 4%; p<0.001 for all the variables. We found 35 women with hypertension that were compared to 331 non-hypertensive women: age 43±9 versus 35±8 years, and waist circumference ³88 cm: 49% versus 15%; both, p<0.001. The prevalence of hypertension among all men was 19%; 32% in those with a waist circumference of ³102; 28% with triglycerides ³150; 63% with glycemia of ³100; p<0.03 for all versus general. Among all women, the prevalence of hypertension was 11%, 25% in those with a waist circumference of ³88; p<0.0008. Multivariate analysis showed that age, glucose blood levels ³100 mg/dl, triglycerides ³150 mg/dl and a waist circumference ³102/88 cm are independent predictors of hypertension. Conclusions The components of the metabolic syndrome are more frequent among subjects with hypertension. In addition, they determine a greater prevalence of hypertension, particularly in men.
