The effect of computed tomography (CT)-guided statin therapy on patients with atypical chest pain and mild-to-moderate coronary artery disease has not been elucidated yet.


A total of 1,952 patients who had 1-69 % stenosis on CT were reviewed retrospectively. After propensity score matching, 643 patients who were prescribed statins after CT (statin users) and 643 patients without statin therapy (statin non-users) were compared. Major cardiovascular events included all-cause death, acute coronary syndrome and stroke.


During a median of 42 months’ follow-up, all-cause death was reported in 17 patients (1.3 %), of whom 6 (0.9 %) were statin users and 11 (1.7 %) statin nonusers. Major cardiovascular events developed in 6.1 % in the statin user group and 5.6 % in the statin non-users (P = 0.812). When evaluated according to plaque subtypes, statins showed significant benefit in patients who had non-calcified or mixed plaque (HR 0.47, 95 % CI 0.22-1.01, P = 0.047). However, in patients with calcified plaques, statins had no benefit in reducing adverse events (P = 0.620).


In most patients with mild-to-moderate coronary artery stenosis on CT, statin therapy has no beneficial effect on reducing adverse events. However, in patients with non-calcified or mixed plaques, statin therapy showed a significant benefit.

Key Points

Multidetector CT now identifies numerous subjects with mild-to-moderate coronary stenosis.

Statin therapy has little beneficial effect on patients with calcified plaques.

However, statins reduce adverse events in those with non-calcified or mixed plaques.
