3 AIM-HIGH: Study Design

4 AIM-HIGH: Lipid Changes At 2 years of follow-up, among patients assigned to niacin: LDL-C decreased by an additional 12.0% (62 mg/dl) HDL-C increased by 25.0% (42 mg/dl)

5 Pourcentage cumulé de patients avec des résultats primaires Étude AIM-HIGH : Résultats P=0.79 by log-rank best Niacine plus statine Placebo plus statine Années No. à risque Placebo plus statine Niacin plus statine

6 AIM-HIGH: Comment "I do not agree with the decision to stop this trial. It was completely inappropriate. The NIH sponsors saw a weak signal of stroke and panicked, and when all the data have come in, this doesn't appear to be an issue. Now we have lost the opportunity to properly answer the very important question of whether niacin adds any benefit in this population with low LDL levels." Dr Steven Nissen

11 SATURN Study: Results

12 SATURN Study: Conclusions Maximal doses of rosuvastatin and atorvastatin resulted in significant regression of coronary atherosclerosis. Despite the lower level of LDL cholesterol and the higher level of HDL cholesterol achieved with rosuvastatin, a similar degree of regression of percent atheroma volume was observed in the two treatment groups.

13 The results of the SHARP trial

14 SHARP: Eligibility History of chronic kidney disease not on dialysis: elevated creatinine on 2 occasions Men: 1.7 mg/dl (150 µmol/l) Women: 1.5 mg/dl (130 µmol/l) on dialysis: haemodialysis or peritoneal dialysis Age 40 years No history of myocardial infarction or coronary revascularisation Uncertainty: LDL-lowering treatment not definitely indicated or contraindicated

15 SHARP: Randomisation structure Randomised (9438) Simva/Eze (4193) Simvastatin (1054) Placebo (4191) Not re-randomised (168) Simv/Eze (4650) Randomised (886) Median follow-up 4.9 years Lost to mortality follow-up 1.5% Placebo (4620)

16 Simv/Eze produces additional reductions in LDL (mmol/l) and apo B (mg/dl) at 1 year Biochemical parameter Simv vs Placebo Simv/Eze vs Simv Simv/Eze vs Placebo Total cholesterol LDL cholesterol HDL cholesterol Non-HDL cholesterol Triglycerides Apolipoprotein B Apolipoprotein A

26 Meta-analysis of New-Onset Diabetes and First Major Cardiovascular Events in 5 Large Trials Comparing Intensive-Dose to Moderate-Dose Statin Therapy CONCLUSION: In a pooled analysis of data from 5 statin trials, intensive-dose statin therapy was associated with an increased risk of new-onset diabetes compared with moderate-dose statin therapy.

27 Courage, Gentlemen PCI for Stable CAD

28 PCI for Stable CAD Initial Coronary Stent Implantation With Medical Therapy vs Medical Therapy Alone for Stable Coronary Artery Disease Conclusion: Initial stent implantation for stable CAD shows no evidence of benefit compared with initial medical therapy for prevention of death, nonfatal MI, unplanned revascularization, or angina. Stergiopoulos K. Arch Intern Med. 2012;172(4):

29 Conclusions To date, the HDL Hypothesis remains unproven LDL-C reduction should remain the aim of preventive therapies Intravascular ultrasound studies are really stup Chronic, stable CAD should be initially treated medically
