Atherosclerosis Diagnosis

At present, tests use to diagnosis for atherosclerosis include angiography, MRI, CT scan, color Doppler examination, fundus examination and pulse wave velocity (PWV).

1. Laboratory tests: the diagnosis of early atherosclerosis. Patients have abnormal lipid metabolism, mainly reflected in increased blood total cholesterol, LDL cholesterol increased, HDL cholesterol, lowering high blood triglycerides, elevated serum β lipoprotein, increased apolipoprotein B, apolipoprotein A lower lipoprotein (α) increased abnormal lipoprotein electrophoresis graphics, over 90% of patients showed Ⅱ or Hyperlipoproteinemia type Ⅳ.

2. Hemorrheology examination: often show increased blood viscosity. Platelet activity can be increased.

3. X-ray examination: In addition to the aforementioned aortic atherosclerosis performance, selective, or electronic computer digital subtraction angiography shows coronary artery, cerebral artery, renal artery, mesenteric artery and limbs atherosclerosis caused by luminal stenosis or aneurysm disease, and lesions where the location, extent and degree of help to determine the indications for surgical treatment.

4. Doppler ultrasonography can help determine the extremities of the arteries and renal artery blood flow.

5. Intravascular ultrasonic imaging and angioscope examination: a direct observation from the arterial cavity atherosclerosis diagnostic methods.

6. Radionuclide examination: help to understand the brain, heart and kidney tissues of the blood supply situation.

7. Echocardiography and ECG: change display characteristics assist in diagnosis of coronary atherosclerosis.

8. Other: limb electrical impedance map of brain electrical impedance, as well as EEG, brain X-ray, computerized tomography X-ray or magnetic resonance imaging can help determine the limbs and cerebral artery function and brain lesions situation.
