Increased carotid artery wall thickness (CAWT), which can cause heart
attack and stroke in many patients, is significantly related to
diabetes and hypertension, according to a study performed at A.O.U. in
Cagliari Sardegna, Italy (Chairman, Professor Giorgio Mallarini).
During the study, 186 patients were evaluated using multidetector row
CT to see if CAWT is associated with cardiovascular risk factors such
as hypertension, diabetes mellitus, dyslipidemia and a history of
smoking. Results showed that there is a statistically significant
relationship between diabetes and hypertension. “There was no
significant statistical correlation between the increase of carotid
wall thickness, smoking and dyslipidemia,” said Luca Saba, MD, lead
author of the study.
“Our group demonstrated that the presence of CAWT greater than 1mm in
patients with diabetes or hypertension is strongly correlated with a
risk to suffer a stroke. Patients at higher risk should be monitored
every 12 months,” said Dr. Saba.
“The detection and evaluation of CAWT together with the study of other
cardiovascular factors allows for improvement in patient follow up and
risk stratification. Imaging as part of the diagnostic process and
management of patients with high cardiovascular risks is important,” he
