Residual Risk Large-scale, randomized, clinical trials of LDL-lowerin therapies have demonstrated significant reduction in CVD events over a wide range of baseline LDL-C levels. However, even with LDL-C levels lowered substantially or at treatment goals with statin therapy, CVD risks are not eliminated and there remains significant residual risk. Intensifying statin therapy may provide additional benefits; this approach, however, has limited potential, owing to tolerability, side effects, and finite efficacy. Further LDL-C lowering may also be achieved with the use of nonstatin agents, such as cholesterol absorption inhibitors and PCSK9 inhibitors, added to statin therapy.
Integral Strategy of CV Prevention Secondary Prevention Healthy lifestyle Medication Primary Prevention Opportunistic screening Risk assessment Healthy lifestyle Medication CVD High Risk patients > 55 years Patients with established CVD: at very high risk of recurrence in absence of prevention. Low risk/ Standard population The recurrence rate or revascularization need in the first year after a CVD event is 50% Annual rate of mortality after AMI is 5-6 times higher than in patients without established CHD. Underlying risk of death in candidate patients who have not received proper secondary prevention : 5% per year, after first AMI 10% per year, after a subsequent AMI The risk of death persists lifelong

Non HDL-C: When to Calculate? Non-HDL-C = TC HDL-C Normal LDL-C, TG and HDL-C Individuals with TG 200mg/dL ( VLDL-C) and ASCVD risk cannot be adequately assessed using LDL-C alone TC = 180 mg/dl TG = 250 mg/dl HDL-C = 30 mg/dl LDL-C = 100 mg/dl Non-HDL = 180-30 =150 mg/dl
Non HDL-C as a Risk Factor Compared with LDL-C, non-hdl-c predictor of risk in pts with TG 200-500mg/dL, DM, insulin resistance, and/or established ASCVD In high-risk individuals, non-hdl-c may be a secondary treatment target Non-HDL-C may be a goal in persistently apo B Non-HDL-C targets when >30 mg/dl than established LDL-C risk levels

Apo B Apo B-100 is the major apolipoprotein of the atherogenic lipoprotein families (VLDL,IDL,LDL) AMORIS (Apolipoprotein-Related Mortality Risk) and Nurses studies, showed that apo B predicting risk to LDL-C, non-hdl- C, or other cholesterol ratios Apo B is more closely associated with the insulin resistance than LDL-C or non-hdl-c IRAS (Insulin Resistance Atherosclerosis Study) revealed that apo B was more closely associated than non-hdl-c with markers such as central adiposity, insulin resistance, thrombosis, and inflammation Apo B can be used as secondary target as non-hdl-c

PCSK9 Inhibitors: Mechanisms of Action, Metabolic Effects, and Clinical Outcomes PCSK9 drugs represent a novel approach to achieving substantial reductions in LDL-C concentrations in a variety of patient populations at high CV risk even on a background of maximally tolerated statin therapy. To date, the primary clinical benefit of evolocumab is a reduction in MI, ischemic stroke, and coronary revascularization but not CV or all-cause mortality. Hess C et al Annu Rev Med 2017, Oct 24
