Background: Left ventricular hypertrophy (LVH) and microalbuminuria are common in hypertensive patients and are often associated with metabolic syndrome (MetS). However, it is not clear whether MetS could modify the association between cardiac and renal damage. Objective: The aim of this study was to assess if the relationship of albumin/creatinine ratio (ACR) and left ventricular mass (LVM) could be independent from MetS in hypertensive overweight/obese patients. Methods: 180 essential hypertensive and overweight/obese (body mass index [BMI] ≥25 kg/m2) patients referred to our Hypertension Centre from January 2006 to April 2009 because of blood pressure (BP) control-related problems were studied. Exclusion criteria were scarce adherence to antihypertensive drug therapy as investigated by the Morisky Medical Adherence Scale (MMAS), heart failure (New York Heart Association III or IV or left ventricular ejection fraction [LVEF] 2.7 or LVM/BSA, as well as a direct correlation between logACR and interventricular diameters and ejection fraction. Regression models including logACR, estimated glomerular filtration rate, BMI, age, hypertension duration, smoking and MetS (as a single variable as well as each single component), showed that only logACR, BMI, hypertension duration and systolic blood pressure (SBP) were independently associated with LVM/h 2.7. Conclusion: Along with BP and BMI, albuminuria measured in a morning urine sample asACRis a valuable low-cost index of cardiac organ damage and increased cardiovascular risk in hypertensive patients independently by MetS. On the other hand, MetS is not an independent risk factor for cardiac damage because it does not seem to add anything more than the sum of each of its components (especially SBP and adiposity indexed by BMI) to the relationship between cardiac and renal subclinical organ damage.
