When it comes to atherosclerosis, it is easy to associate it with cardiovascular diseases. In fact, in addition to heart attacks and strokes related to atherosclerosis, there are many other hazards that may be caused by atherosclerosis. Experts point out that arterial blood vessels throughout the body, so atherosclerosis can have an impact on a number of organs. Therefore, early diagnosis and early treatment of patients are especially important. Diagnosis methods of atherosclerosis: 1.Patients over 40 years old, if they have aortic widening and distortion and can exclude other diseases, it suggests the possibility of aortic atherosclerosis. 2.If vertigo or gait instability suddenly appears without signs of increased intracranial pressure, cerebral blood supply deficiency caused by basilar artery atherosclerosis should be suspected. 3. Transient retrosternal and precordial dullness or pressure after activity should be suspected of insufficient coronary artery supply. 4.Nocturia is often one of the early symptoms of renal atherosclerosis. In addition, patients often have atherosclerosis susceptibility factors, such as hypertension, hypercholesterolemia, hypoHDLemia, diabetes mellitus and smoking. For example, selective electrocardiogram, radionuclide heart, brain, kidney and other organ scans, Doppler ultrasonography, and selective angiography can help to clarify the diagnosis. Clinical differentiation from inflammatory arterial lesions (e.g., polyarteritis major, thrombo-occlusive vasculitis, etc.) and congenital arterial stenosis (e.g., aortic, renal artery stenosis, etc.) is often required. Inflammatory arterial diseases tend to have inflammatory manifestations such as hypothermia and increased sedimentation, while congenital aortic stenosis has a young age of onset and is not associated with atherosclerotic predisposing factors.
