ST FRANCIS RANDOMIZED TRIALRandomized Double Blind Placebo Controlled Trial of Atorvastatin in the Prevention of Cardiovascular EventsAmong Individuals With Elevated CAC Score Arad Y et al. J Am Coll Cardiol 2005: 46: 166-172. Atorvastatin 20 mg (N=490) MI Stroke CVD Death CABG/PTCA No Prior CVD Men, Women 50-70 years CAC >80% of age-gender Placebo (N=515) Mean duration of treatment was 4.3 years. Treatment reduced low-density lipoprotein cholesterol by 40%, while reducing clinical endpoints by 30% (6.9% vs. 9.9%), and MI/ Death by 44% (NNT = 30) Event rates were more significantly reduced in participants with baseline calcium score >400 (8.7% vs. 15.0%, p=0.046 [42% reduction]). NNT = 15.8

Does CAC scanning improve outcomes? Rozanski. Berman. EISNER. JACC 2011;57:1622. CACS 0 = 631. CACS>400 = 109.

“assessing CAC is likely to be the most useful of the current approaches to improving risk assessment among individuals found to be at intermediate risk after formal risk assessment.” ACC/AHA 2013 PREVENTION GUIDELINES– Goff JACC 2014

ROMICAT-II (Hoffman et al, NEJM 2012) - Notable differences to the prior randomized studies: -TIMI scores did not limit entry criteria - SOC included any available management strategy deemed appropriate by the treating physicians. These choices included EKG treadmill testing, stress echo and stress single photon emission CT, as well as no further diagnostic testing
