It is not possible to determine the CAD one RADS classification based on the description, and the classification needs to be determined based on the degree of luminal stenosis. In the case of calcified and non-calcified plaques in the anterior descending branches of the coronary arteries, it was not possible to determine the CAD one RADS classification. Imaging classifies CAD one RADS into 7 grades: The maximum degree of stenosis in the lumen diameter is 0%, indicating the absence of plaque and stenosis is grade 0; 1% to 24% stenosis, very small stenosis or plaque but did not cause stenosis, belongs to grade 1; in addition, 25% to 49% with mild stenosis is grade 2; 50% to 69% moderate stenosis, grade 3; 70% to 99% severe stenosis, belongs to grade 4a; the left main stenosis of > 50% or the obstruction of three blood vessels of >70% For severe stenosis, it belongs to grade 4b; 100% stenosis is complete occlusion, which belongs to grade 5. Coronary artery stenosis requires hospitalization, and treatment should be guided by the doctor’s diagnosis.
