There was no evidence of any serious harm caused by statin prescription .
Evidence available to date showed that primary prevention with statins is likely to be cost-effective and may improve patient quality of life .
Recent findings from the Cholesterol Treatment Trialists study using individual patient data meta- analysis indicate that these benefits are similar in people at lower ( < 1 % per year ) risk of a major cardiovascular event .
AUTHORS ' CONCLUSIONS Reductions in all-cause mortality , major vascular events and revascularisations were found with no excess of adverse events among people without evidence of CVD treated with statins
BACKGROUND Reducing high blood cholesterol , a risk factor for cardiovascular disease ( CVD ) events in people with and without a past history of CVD is an important goal of pharmacotherapy .
Statins are the first-choice agents .
Previous review s of the effects of statins have highlighted their benefits in people with CVD .
The case for primary prevention was uncertain when the last version of this review was published ( 2011 ) and in light of new data an up date of this review is required .
OBJECTIVES To assess the effects , both harms and benefits , of statins in people with no history of CVD .
Rationale, design, methods and baseline demography of participants of the Anglo-Scandinavian Cardiac Outcomes Trial
Objective To test the primary hypothesis that a newer antihypertensive treatment regimen ( calcium channel blocker ± an angiotensin converting enzyme inhibitor ) is more effective than an older regimen ( β-blocker ± a diuretic ) in the primary prevention of coronary heart disease ( CHD ) . To test a second primary hypothesis that a statin compared with placebo will further protect against CHD endpoints in hypertensive subjects with a total cholesterol ⩽ 6.5 mmol/l . Design Prospect i ve , r and omized , open , blinded endpoint trial with a double-blinded 2 × 2 factorial component . Setting Patients were recruited mainly from general practice s. Patients Men and women aged 40–79 were eligible if their blood pressure was ⩾160 mmHg systolic or ⩾ 100 mmHg diastolic ( untreated ) or ⩾140 mmHg systolic or ⩾ 90 mmHg diastolic ( treated ) at r and omization . Interventions Patients received either amlodipine ( 5/10 mg ) ± perindopril ( 4/8 mg ) or atenolol ( 50/100 mg ) ± bendroflumethiazide ( 1.25/2.5 mg ) + K+ with further therapy as required to reach a blood pressure of ⩽140 mmHg systolic and 90 mmHg diastolic . Patients with a total cholesterol of ⩽ 6.5 mmol/l were further r and omized to receive either atorvastatin 10 mg or placebo daily . Main outcome measure Non-fatal myocardial infa rct ion ( MI ) and fatal coronary heart disease ( CHD ) . Results 19 342 men and women were initially r and omized , of these 10 297 were also r and omized into the lipid-lowering limb . All patients had three or more additional cardiovascular risk factors . Conclusions The study has 80 % power ( at the 5 % level ) to detect a relative difference of 20 % in CHD endpoints between the calcium channel blocker-based regimen and the β-blocker-based regimen . The lipid-lowering limb of the study has 90 % power at the 1 % level to detect a relative difference of 30 % in CHD endpoints between groups
