The results of the Study of Heart and Renal Protection (SHARP) Colin Baigent, Martin Landray on behalf of the SHARP Investigators Disclosure: SHARP was sponsored, designed, run, and analysed by the University of Oxford. Funding was received from Merck, the UK MRC, British Heart Foundation, and Australian NHMRC.
SHARP: Rationale Risk of vascular events is high among patients with chronic kidney disease Lack of clear association between cholesterol level and vascular disease risk Pattern of vascular disease is atypical, with a large proportion being non-atherosclerotic Previous trials of LDL-lowering therapy in chronic kidney disease are inconclusive
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 revascularization Uncertainty: LDL-lowering treatment not definitely indicated or contraindicated
Age-standardized event rate (per 100 person-yr) CKD Subgroup Relationship Between Estimated GFR (egfr) and Clinical Outcomes Death from any cause Cardiovascular events Any hospitalization Total events = 51,424 Total events = 139,011 Total events = 554,651 egfr (ml/min/1.73 m 2 ) Kaiser Permanente Renal Registry, n=1,120,295 adults aged 20 years Median follow-up = 2.84 years Go AS et al.

SHARP: Conclusions No increase in risk of myopathy, liver and biliary disorders, cancer, or nonvascular mortality No substantial effect on kidney disease progression Two-thirds compliance with eze/simv reduced the risk of major atherosclerotic events by 17% (consistent with meta-analysis of previous statin trials) Similar proportional reductions in all subgroups (including among dialysis and non-dialysis patients) Full compliance would reduce the risk of major atherosclerotic events by one quarter, avoiding 30 40 events per 1000 treated for 5 years
