| Abstract | Ultrasound Speckle Tracking, a novel technique used to assess regional mechanics of carotid wall and plaques. We hypothesized that vulnerable carotid plaques have higher intraplaque stretch which resulted in an increased difference in deformation between cap and core Methods Study population consisted of 39 patients with carotid atherosclerosis: 11 with acute atherothrombotic stroke and 28 asymptomatic patients with similar demographics and risk factors. For each plaque, maximum circumferential and longitudinal strain (Sc_Sl) and strain rate (SRc_SRl) were measured for cap, core and base. Plaque characteristics (echogenicity, degree of stenosis, surface, etc) were assessed. All plaques were divided into hyperechogenic(19) and echolucent(20) ones. Results Echolucent plaques underwent significantly higher deformations than hyperechogenic ones (Sc=4.06 vs 3.25, p<0.05) and they had significant difference in deformation between cap and core(p<0.05) whereas hyperechogenic plaques had no difference in deformation between segments (Sc=5.2_4.2_2.8 and 3.5_3.1_3.2 for cap, core and base of echolucent and hyperechogenic plaques, respectively). Moderate negative correlations were observed between echogenicity and deformations (r=−0.35_p<0.001 for cap_Sc). Symptomatic plaques had higher difference between cap and core Sl. Plaque internal deformation coefficient, Cpid=[(cap_Sl-core_Sl)/(core_Sl+base_Sl)]x100 was developed to quantify the relative deformation of different plaque segments. Based on ROC-analysis, plaques with Cpid>22.2 were associated with an ischemic event (sensitivity-55%, specificity-87%, AUC=0.693, p=0.0485). Logistic regression confirmed that Cpid>22.2 is an independent predictor of plaque vulnerability, OR=3.7, 95%_CI=0.8–22.8, controlling for age, gender, plaque length, degree of stenosis, echogenicity. Conclusions Mobility of echolucent plaques exceeds those of hyperechogenic ones. Difference in mobility between plaque segments may help identify plaque vulnerability. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
