摘要

AIMS: The aim of our study was to assess the two-dimensional carotid strain as an index of arterial stiffness in a population of patients without carotid atherosclerotic plaques. METHODS AND RESULTS: Two-dimensional carotid strain, carotid intima-media thickness (CIMT), stiffness index (beta), Peterson's elastic modulus, and distensibility coefficient were evaluated in 47 patients. For all patients, cardiovascular risk scores were calculated. Peak systolic circumferential strain was significantly correlated with conventional indices of arterial stiffness and with the CIMT. Peak systolic circumferential strain adjusted for pulse pressure was the only parameter that showed a significant difference between the three cardiovascular risk groups in which patients were classified. Two-dimensional carotid strain showed an excellent reproducibility. CONCLUSION: The two-dimensional strain allows the assessment of carotid arterial mechanics. Probably the assessment of arterial stiffness allows a better risk stratification of patients.
