How common is carotid artery plaque?

Generally, a considerable number of people have plaques in the carotid arteries. The detailed analysis is as follows:

The presence of plaques in the carotid arteries is a common condition, particularly among older adults or individuals with risk factors for atherosclerosis—a disease characterized by plaque buildup in the arteries. The carotid arteries are major blood vessels located on both sides of the neck that supply oxygen-rich blood to the brain. Plaques consist of fatty substances that gradually accumulate on the inner walls of the arteries over time. Risk factors for developing carotid artery plaques are similar to those for general atherosclerosis and include hypertension, high cholesterol, smoking, diabetes, obesity, a family history of cardiovascular disease, and unhealthy diet or lifestyle habits. Other factors such as age, gender, and genetic predisposition may also contribute to the formation of carotid artery plaques. Therefore, a significant number of people have carotid artery plaques.

Arterial plaques can narrow or block the arteries, disrupting blood flow to the brain and increasing the risk of stroke or transient ischemic attack (TIA). However, not everyone with carotid artery plaques will experience symptoms or complications, and the severity of the plaques and associated risks vary from person to person. Treatment options may include lifestyle modifications, medication management to control risk factors, and in certain cases, surgical or endovascular interventions such as carotid endarterectomy or carotid stenting to remove or bypass the plaque and restore proper blood flow. Individuals who suspect they have carotid artery plaques or possess risk factors for atherosclerosis should seek medical attention promptly.
