Calcification score shall refer to the coronary artery calcification score, whose normal value is usually 0. Clinically, the normal value of coronary artery calcification score is 0. When the patient’s score value is between 1 and 99, it suggests mild plaque, between 100 and 399, it suggests moderate plaque, and when the score is more than 400, it suggests that the patient’s plaque in the coronary artery is more serious. The Coronary Calcification Score is generally used to assess the degree of coronary atherosclerosis, with higher scores indicating more severe atherosclerosis. However, it is worth mentioning that the elevation of this test alone cannot make an accurate judgment, and the diagnosis of coronary artery atherosclerosis in the clinic needs to be combined with some other auxiliary tests, which need to be carried out by professional doctors. To summarize, the normal value of coronary artery calcification score is generally 0, if found to be elevated, it is necessary to consult a doctor in time.
