3.3.3.1 Primary Prevention (Patients Without ASCVD)
For primary prevention, moderate-dose statin therapy is recommended for those 40 years and older (80,87,88), though high-intensity therapy may be considered on an individual basis in the context of additional ASCVD risk factors. The evidence is strong for patients with diabetes aged 40–75 years, an age-group well represented in statin trials showing benefit. Since risk is enhanced in patients with diabetes, as noted above, patients who also have multiple other coronary risk factors have increased risk, equivalent to that of those with ASCVD. As such, recent guidelines recommend that in patients with diabetes who have multiple ASCVD risk factors, it is reasonable to prescribe high-intensity statin therapy (12,89). Furthermore, for patients with diabetes whose ASCVD risk is >20%, i.e., an ASCVD risk equivalent, the same high-intensity statin therapy is recommended as for thosewith documented ASCVD (12). The evidence is lower for patients aged >75 years; relatively few older patients with diabetes have been enrolled in primary prevention trials. However, heterogeneity by age has not been seen in the relative benefit of lipid-lowering therapy in trials that included older participants (78,85,86), and because older age confers higher risk, the absolute benefits are actually greater (78,90). Moderate-intensity statin therapy is recommended in patients with diabetes that are 75 years or older. However, the risk-benefit profile should be routinely evaluated in this population, with downward titration of dose performed as needed. See Section 12 “Older Adults” for more details on clinical considerations for this population.
