Arterial plaques are typically asymptomatic initially. However, over time, they can grow, restricting blood flow and leading to various symptoms. This plaque formation commonly occurs in the coronary arteries supplying the heart, the carotid arteries carrying blood to the brain, and the peripheral arteries leading to the legs. Depending on the affected area, these conditions can cause symptoms such as pain, dizziness, shortness of breath, or loss of balance while walking.
