Global cardiovascular disease risk management in Italian patients with metabolic syndrome in the clinical practice setting

Background: Metabolic syndrome is a highly prevalent condition in the Italian population. This study assesses the feasibility and efficacy of a multifactorial approach for primary prevention of cardiovascular disease risk assessment in patients with metabolic syndrome in the daily clinical practice setting. Methods: 726 patients were enrolled (males : females = 7 : 3), their ages ranging from 26 to 70 years, with metabolic syndrome and cardiovascular death risk ≥5%, computed by means of the European Systematic COronary Risk Evaluation (SCORE) algorithm. The first phase (3 months) consisted of an improvement in lifestyle and, if necessary, the initial administration of an antihypertensive therapy (valsartan 160 mg/day for patients with blood pressure ≥140/90 mmHg and ≥130/80 mmHg for diabetic patients). During phase 2 (6 months), patients with systolic blood pressure (SBP) ≥140 mmHg and/or diastolic blood pressure (DBP) ≥90 mmHg (≥130/80 mmHg for diabetic patients) were administered valsartan 160 mg/day + hydrochlorothiazide 12.5 mg/day combined; those with total cholesterol levels ≥190 mg/dL (≥175 mg/dL for diabetic patients) started treatment with fluvastatin 80 mg prolonged release (XL), as prescribed in the guidelines. A control group was approached with another conventional treatment. Results: After 9 months of monitoring, the SBP dropped by 27 mmHg in the valsartan-treated patients and by 11 mmHg in the control group, while the DBP dropped by 12 mmHg in the former group and 2 mmHg in the latter. Total cholesterolaemia was reduced by 47 mg/dL in patients undergoing fluvastatin and valsartan therapy, by 19 mg/dL in those treated with valsartan only and by 33 mg/dL in those administered another conventional treatment. Relative risk reduction observed after 9 months, compared with the beginning of the study, was almost 48% in the valsartan/valsartan + fluvastatin group, versus 28% observed with the other conventional treatment. The reduction of risk at 60 years of age was an average of 39% at 3 months and 48% at 9 months, compared with the beginning of the study. Therapeutic success was accomplished with 78% of the patients treated with valsartan/valsartan + fluvastatin, compared with 47% of patients in the conventional therapy group. Conclusion: The present study demonstrated that the normalization of the main cardiovascular risk factors in patients with metabolic syndrome may be easily achieved in standard clinical practice settings, by leading an adequate lifestyle and, if necessary, the administration of antihypertensive and/or lipid-lowering monotherapy at the usual doses. © 2008 Adis Data Information BV.
