CAROTID ARTERY PLAQUE PROGRESSION: PROPOSAL OF A NEW PREDICTIVE SCORE AND ROLE OF CAROTID INTIMA-MEDIA THICKNESS (ID 798)
Abstract
Background And Aims
Longitudinal changes in carotid intima-media thickness (IMT) and plaque are considered markers of atherosclerosis progression and predictors of cardio and cerebrovascular events. However, a clinical predictive risk score of plaque progression is currently lacking. We aimed to investigate if a new proposed risk score (HAD2S score) composed by the sum of single vascular risk factors (Hypertension, Age ≥ 75 years, Diabetes, Dyslipidemia and Smoking) and baseline IMT were predictive of plaque progression.
Methods
We performed a retrospective analysis on real-life prospectively collected data. We include all patients with any detectable carotid plaque. The plaque score was defined as 0: no plaque or stenosis <30%; 1: stenosis between 30-49%; 2: stenosis between 50-69%; 3: stenosis between 70-99% and 4: occlusion. Vascular risk factors, stenosis progression, IMT, Peak Systolic Velocity and End Diastolic Velocity were investigated in all patients at baseline and at a median follow-up of 36.6 months (IQR 39.6-34.3). HAD2S score was calculated for all patients.
Results
The 340 included patients were aged 69.9 (9.1) years (52% men). 25% of subjects had plaque progression. Mean IMT at baseline was associated with plaque progression (p<0.0001). Patients with progression had a mean IMT at baseline of 0.86 (0.17) while those who didn’t present progression had a mean IMT at baseline of 0.77 (0.18). The 87.2% of patients with plaque progression had a HAD2S score ≥ 2 (p=0.044).
Conclusions
Our data demonstrates that mean IMT at baseline and initial HAD2S score ≥ 2 could be considered predictors of plaque progression.
