Carotid Color Doppler Ultrasound typically refers to the examination of the carotid arteries using color Doppler ultrasound technology. Carotid Color Doppler Ultrasound usually cannot detect heart problems. It is primarily used to assess the carotid artery wall for abnormalities such as carotid thickness, plaques, occlusion, thrombosis, and other symptoms. This examination can diagnose conditions like carotid arteritis, carotid atherosclerosis, and carotid aneurysms. However, it generally cannot detect heart issues. If heart-related symptoms arise, it is crucial to promptly communicate with a doctor. Tests such as electrocardiography (ECG), Holter monitoring, and echocardiography can be conducted to determine whether the patient has heart disease, thereby preventing delays in diagnosis and treatment. When experiencing symptoms of discomfort, one should promptly visit a reputable hospital. Under the guidance of a doctor, systematic examinations can be conducted to identify the specific cause, which can then be treated accordingly. This approach facilitates the recovery process. In daily life, it is also important to develop good living habits, maintain a positive mindset, and avoid excessive anxiety, which are beneficial for overall health.
