Arteriosclerosis requires the following examinations: 1. ECG or carotid color ultrasound examination. These examinations can mainly judge whether there is arteriosclerosis in the heart, cerebral vessels and other parts, which causes ischemia. Because the carotid artery is the main artery of the human body, color ultrasound can detect whether there is plaque formation or thickening of the intima, thus helping to determine whether there is atherosclerosis, while ECG can determine whether there is insufficient blood supply to the heart, and these examinations are non-invasive. 2. Test blood fat, blood sugar and measure blood pressure. The purpose of these examinations is to determine whether there is a risk factor of atherosclerosis. If there is a risk factor of atherosclerosis, it is also necessary to actively take measures to control it. Through these examinations, we can judge the location and severity of arteriosclerosis, and provide basis for further treatment.
