OBJECTIVE:To evaluate the relationships among micro-albuminuria, blood pressure and measurements of left ventricular structure and function in centrally and peripherally obese subjects compared with members of a lean control group.METHODS:Centrally obese subjects were subdivided according to whether they had levels of micro-albuminuria higher than 30 mg/24 h (micro-albuminuric group) or lower than or equal to 30 mg/24 h (normo-albuminuric group). For all the subjects we measured heart rate, casual mean blood pressure (MBP), 24 h MBP, total cholesterol level, high-density lipoprotein cholesterol, lipoprotein (a) level, fasting immunoreactive insulin level, plasma renin activity, plasma aldosterone level and micro-albminuria (UAE) by current methods. Left ventricular mass indexed for body height, left ventricular diastolic and systolic diameters, interventricular septal thickness and left ventricular ejection fraction were measured by echocardiography. Peak filling rate was also calculated by radionuclide study. Family history of cardiovascular disease was evaluated for all the obese subjects.RESULTS: Lipoprotein (a) level, total cholesterol level, 24 h MBP and interventricular septal thickness were significantly (P < 0.05) greater for micro-albuminuric than they were for normo-albuminuric centrally obese subjects, whereas high-density lipoprotein cholesterol level and left ventricular ejection fraction were significantly (P < 0.05 lower. In addition, UAE levels of centrally obese subjects were significantly (P < 0.05) higher than those of peripherally obese subjects. UAE of all the centrally obese subjects was correlated directly to lipoprotein (a) level (r = 0.33, P < 0.009), 24 h MBP (r = 0.41, P < 0.002), interventricular septal thickness (= 0.36, P < 0.005) and family history of cardiovascular disease (r = 0.33, P < 0.007). Multiple regression analysis indicated that UAE was independently related to 24 h MBP and family history of cardiovascular disease. CONCLUSION:Our data indicated that measurement of micro-albuminuria is useful for evaluating cardiovascular risk profiles of obese subjects with a central fat distribution
