Arteriosclerosis is a relatively common disease in our daily life. After being diagnosed with arteriosclerosis, the following tests should be considered: Firstly, blood tests, such as lipid panels, are necessary to determine the levels of blood lipids. Based on the results, medication might be required for treatment. Secondly, arterial Doppler ultrasound is useful as it can effectively detect the presence and severity of arteriosclerosis. Thirdly, arterial angiography is recommended when there is a strong suspicion of arterial narrowing due to arteriosclerosis, leading to coronary heart disease or other conditions. This test helps in determining the severity of the arteriosclerosis and in deciding the treatment plan.
