TLDR
Cross-sectional and longitudinal quality control of the ultrasound measurements implemented throughout ELSA showed high reliability for all endpoints at all time points except for single maximum IMT (Tmax) and internal carotid IMT and within-reader reliability remained excellent.
Abstract
BackgroundThe European Lacidipine Study of Atherosclerosis (ELSA) was a prospective, randomized, double-blind, multinational interventional trial using B-mode ultrasound measurement of carotid intima–media thickness (IMT) in 2259 hypertensive individuals. ELSA showed that 4-year treatment with the c

Noninvasive Assessment of Subclinical Atherosclerosis in Children and Adolescents: Recommendations for Standard Assessment for Clinical Research: A Scientific Statement From the American Heart Association

TL;DR: This scientific statement was written to review the current literature on the noninvasive assessment of atherosclerosis in children and adolescents, make recommendations for the standardization of these tools for research, and stimulate further research with a goal of developing valid and reliable techniques with normative data for nonin invasive clinical evaluation of atheosclerosis in Pediatrics.

Preclinical atherosclerosis due to HIV infection: carotid intima-medial thickness measurements from the FRAM study.

TL;DR: The stronger association of HIV infection with IMT in the internal/bulb region compared with the common carotid may explain previous discrepancies in the literature and was similar to that of traditional CVD risk factors, such as smoking.

Visit-to-Visit Blood Pressure Variability, Carotid Atherosclerosis and Cardiovascular Events in the European Lacidipine Study on Atherosclerosis

TL;DR: In mildly to moderately hypertensive patients, carotid intima-media thickness and cardiovascular outcomes were related to the mean clinic or ambulatory SBP achieved by treatment but not to on-treatment visit-to-visit clinic or 24-hour BP variability, suggesting inconsistency of BP control between visits plays a less important prognostic role than long-term average BP levels.

Baseline values but not treatment-induced changes in carotid intima-media thickness predict incident cardiovascular events in treated hypertensive patients: findings in the European Lacidipine Study on Atherosclerosis (ELSA).

TL;DR: ELSA shows that carotid intima-media thickening and plaques are important added risks of cardiovascular outcomes in a treated hypertensive population independently of blood pressure and traditional risk factors, but the analysis failed to show a predictive role of treatment-dependent IMT changes.

Calcium Antagonist Lacidipine Slows Down Progression of Asymptomatic Carotid Atherosclerosis Principal Results of the European Lacidipine Study on Atherosclerosis (ELSA), a Randomized, Double-Blind, Long-Term Trial

TL;DR: The greater efficacy of lacidipine on carotid IMT progression and number of plaques per patient, despite a smaller ambulatory blood pressure reduction, indicates an antiatherosclerotic action of lacIDipine independent of its antihypertensive action.

Final Outcome Results of the Multicenter Isradipine Diuretic Atherosclerosis Study (MIDAS): A Randomized Controlled Trial

TL;DR: The rate of progression of mean maximum IMT in carotid arteries, the surrogate end point in this study, did not differ between the 2 treatment groups, and the increased incidence of vascular events in patients receiving isradipine compared with hydrochlorothiazide is of concern.

Risk Factors for Progression of Common Carotid Atherosclerosis: The Atherosclerosis Risk in Communities Study, 1987–1998

TL;DR: In this paper, the authors examined the association of baseline risk factors or change in risk factors with change in intima-media thickness over follow-up (1987-1998) in the Atherosclerosis Risk in Communities (ARIC) population-based cohort (baseline: age 45-64 years, n = 15,792).
