5 ACC/AHA Guidelines Recommend Lowering LDL-C to Reduce the Risk of a CVD Event Patients >21 yr of age without heart failure or ESRD Screen for ASCVD risk factors Measure LDL-C Clinical ASCVD Diabetes mellitus (type 1 or 2) and age of yr and LDL-C mg/dl No diabetes mellitus and age of yr and LDL-C mg/dl LDL-C 190 mg/dl Calculate 10-year risk* of ASCVD Calculate 10-year risk* of ASCVD High-intensity statin therapy If risk <7.5%*, moderateintensity statin therapy If risk 7.5%*, high-intensity statin therapy If risk 7.5, moderate-to-highintensity statin therapy High-intensity statin therapy 2013 ACC/AHA guidelines state that reduction of CVD events according to risk should be achieved with statin treatment in 4 groups with increased CV risk ACC=American College of Cardiologists; AHA=American Heart Association; ASCVD= atherosclerotic cardiovascular disease; ESRD=end-stage renal disease; LDL-C=low-density lipoprotein cholesterol; RCT=randomized controlled trials. Goff et al, JACC 2013 epub Nov 12.; Stone et al. JACC 2014; 63: ; Keaney et al. NEJM 2013; epub Nov 27.

6 LDL-C Lowering Therapies Reduce CV-Risk 2013 ACC/AHA guidelines state that lowering LDL-C lowers ASCVD risk, but since no RCTs have been done to specifically treat to goals, an optimal goal is not supported 2013 ACC/AHA guidelines do not routinely allow for non-statin therapy to treat high-risk patients who: Have a less-than-anticipated response to statins Are unable to tolerate a less-than-recommended intensity of a statin Are completely statin intolerant ACC=American College of Cardiologists; AHA=American Heart Association; ASCVD= atherosclerotic cardiovascular disease; HDL-C=high-density lipoprotein cholesterol; LDL-C=low-density lipoprotein cholesterol; RCT=randomized controlled trials.

14 Association Between Lowering LDL-C and Cardiovascular Risk Reduction Among Different Therapeutic Interventions Weighted Between-Group Difference in Achieved Low-Density Lipoprotein Cholesterol (LDL-C) Level and Relative Risk for Major Vascular Events for Each Class of Intervention MG Silverman et al - JAMA. 2016;316(12): The RR for major vascular events per 1- mmol/l reduction in LDL-C was: 0.77 (95%CI, ; P <.001) for statins 0.75 (95%CI, ; P =.002) for established non-statin interventions that work primarily via up-regulation of LDL receptor expression (ie, diet, bile acid sequestrants, ileal bypass, and ezetimibe) 0.61 (95%CI, ) for PCSK9i (P =.25). The use of statin and non-statin therapies that act via up-regulation of LDL receptor expression to reduce LDL-C were associated with similar RRs of major vascular events per change in LDL-C.
