摘要
Background Hypertension guidelines underline the importance of quantification of total cardiovascular risk; an extensive evaluation of target organ damage (TOD) may increase the number of patients classified at high-added cardiovascular risk. Objective To assess the effect of the evaluation of different forms of TOD, in addition to 'routine' workup, on cardiovascular risk stratification in a general population sample in Northern Italy. Methods In 385 patients (age 57 +/- 10 years, 44% men, 64% hypertensives, 32% treated), left ventricular and carotid artery structure and carotid-femoral pulse wave velocity (PWV) were measured. All patients underwent laboratory examinations. Patients were divided into risk categories according to European Society of Hypertension/European Society of Cardiology guidelines before and after TOD evaluation. Results After routine workup, patients were classified as follows: 6% at average cardiovascular risk, 35% at low cardiovascular risk, 25% at moderate cardiovascular risk, 33% at high cardiovascular risk and 1% at very high cardiovascular risk. The proportion of patients at low or moderate cardiovascular risk reclassified at high cardiovascular risk were 5, 14, 30 and 14% after echocardiography, measurement of albuminuria and estimated glomerular filtration rate, carotid ultrasound and PWV, respectively (chi(2) P<0.001 for all vs. routine). Assessment of PWV in addition to echocardiography led to an increase of the proportion of patients at high risk (from 5 to 15%, P<0.001), as for PWV in addition to albuminuria, estimated glomerular filtration rate or both (from 14 to 31%, P<0.01), but did not affect risk stratification in addition to carotid ultrasound (from 30 to 34%, P=NS). Conclusion Our data suggest that measurement of PWV may significantly change cardiovascular risk stratification in addition to echocardiography and to detection of albuminuria and/or of a reduction of estimated glomerular filtration rate, but not after carotid ultrasound. Our results confirm that evaluation of different forms of TOD is useful for a more accurate assessment of global cardiovascular risk.
