Are carotid artery plaques serious?

Carotid artery plaque is a manifestation of atherosclerosis. To date, the exact etiology of atherosclerosis remains incompletely understood. However, hyperlipidemia, hypertension, hyperglycemia, smoking, and obesity are all well-established risk factors. So, how serious is carotid artery plaque? Below, we address this question.

How serious is carotid artery plaque?

In general, the presence of carotid artery plaque is considered clinically significant, as it can readily lead to vascular stenosis—or even complete occlusion—and predispose to thrombus formation. If a plaque becomes dislodged, it may travel through the arterial circulation and potentially cause cerebral embolism, pulmonary embolism, or heart failure; in severe cases, it may even threaten the patient’s life. Therefore, prompt attention and appropriate management are essential.

Typically, under a physician’s guidance, antiplatelet agents—such as aspirin—may be prescribed, along with lipid-lowering medications—particularly statins—which help stabilize existing plaques. Patients should undergo regular follow-up examinations at the hospital and pay close attention to dietary modifications: high-salt, high-sugar, and high-fat foods should be avoided. Smoking and alcohol consumption should ideally be discontinued altogether. A light, easily digestible diet is recommended.
