Carotid artery disease is a condition characterized by the narrowing or blockage of the carotid arteries, the major blood vessels that supply oxygenated blood to the brain. This narrowing is typically caused by the buildup of fatty deposits, known as plaque, on the inner walls of the arteries. As the disease progresses, it can impede blood flow to the brain, increasing the risk of stroke. Carotid artery disease often develops gradually and may not exhibit noticeable symptoms until a significant blockage occurs. Common risk factors include age, smoking, high blood pressure, and elevated cholesterol levels. Diagnosis often involves imaging tests such as ultrasound, CT scans, or magnetic resonance angiography. Treatment options range from lifestyle modifications and medications to surgical interventions like carotid endarterectomy or angioplasty with stent placement. Timely detection and management of carotid artery disease are crucial in preventing potentially severe consequences such as stroke and cognitive impairment. Individuals with risk factors should maintain regular medical check-ups to monitor and address any signs of this vascular condition.
