Using Coronary Artery Calcification Combined with Pretest Clinical Risk Assessment as a Means of Determining Investigation and Treatment in Patients Presenting with Chest Pain in a Rural Setting

Table 2

Calcium score versus pretest risk.

Calcium score	No = low pretest risk	= medium pretest risk	= high pretest risk
Zero calcium score, male	18	20	21
Zero calcium score, female	114	52	29
Calcium score; 1–400, male	11	24	76
Calcium score; 1–400, female	15	15	17
Calcium score; >400, male	1	2	30
Calcium score; >400, female	3	5	9

This table shows the numbers of patients with a particular calcium score range and their pretest risk, which is classified as low, medium, or high. The majority of patients with a zero calcium score have a low pretest risk, but significant numbers of patients have a zero calcium score with a high pretest risk.
