Abstract | OBJECTIVES: METHODS: One hundred and twenty-eight essential hypertensive patients were included in the study: 51 with MS and 77 without MS. Clinical, echocardiographical and biochemical parameters, and levels of both N-terminal (NT)-proANP and alphaANP were assessed. RESULTS: Hypertensive patients affected by MS had higher LVM and increased frequency of LVH. NT-proANP levels were significantly lower in MS, independent of waist circumference (WC). Log(NT-proANP) levels were significantly inversely related to left ventricular mass index (LVMI) (beta = -0.360, P < 0.001) and LVM/height (beta = -0.370, P < 0.001) in the whole hypertensive population by multiple linear regression analysis. The relationship of log(NT-proANP) with LVM was more enhanced in patients with MS. CONCLUSIONS: The present study demonstrates that levels of NT-proANP are significantly reduced in hypertensive patients affected by MS, and they are significantly inversely related to the increased LVM observed in these patients. Our findings, while supporting previous experimental and clinical evidence of the antihypertrophic role of ANP in hypertension, may help to identify one of the possible mechanisms directly underlying LVH in MS.
