Study summary

The rupture or erosion of an atherosclerotic plaque with thrombosis or embolization often underlie heart attacks and strokes. The early identification of patients with atherosclerotic plaques prone to rupture or erosions, vulnerable plaques (VP), and their treatment before the occurrence of events is, therefore, one of the greatest cardiovascular challenges today. Possible approaches for early detection of VP include imaging techniques allowing visualization of plaque structure, circulating biomarkers and better understanding of the pathophysiologic mechanisms of the disease. In the carotid plaque imaging project the investigators study human atherosclerotic plaques (that are removed by endarterectomy) to disclose their underlying structure and mechanisms, finding possible novel therapeutic targets or markers for VP. The investigators also study plaque structure with imaging methods and try to develop new ways to detect VP using circulating or imaging markers.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients older than 18 years old, male or female that are eligible for carotid endarterectomy due to atherosclerosis and that can provide .

Exclusion criteria

Exclusion Criteria:

  • Patients younger than 18 years old that cannot provide ; pregnant.
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
