Results : BP and lipid levels tended to come together soon in the post-trial period .
Conclusion : Benefits of BPL and lipid lowering on all-cause and cardiovascular mortality were persistent , but attenuated , after discontinuation of r and omized treatment , indicating the importance of continuing therapy
Objective : Persistent long-term benefits after discontinuation of treatment have been suggested for blood pressure-lowering and lipid-lowering treatment .
We conducted a systematic review to assess the long-term effects of  blood pressure ( BP ) lowering ( BPL ) and lipid lowering on all-cause and cardiovascular mortality after discontinuation of r and omized treatment .
Pravastatin in elderly individuals at risk of vascular disease (PROSPER): a randomised controlled trial
BACKGROUND Although statins reduce coronary and cerebrovascular morbidity and mortality in middle-aged individuals , their efficacy and safety in elderly people is not fully established . Our aim was to test the benefits of pravastatin treatment in an elderly cohort of men and women with , or at high risk of developing , cardiovascular disease and stroke . METHODS We did a r and omised controlled trial in which we assigned 5804 men ( n=2804 ) and women ( n=3000 ) aged 70 - 82 years with a history of , or risk factors for , vascular disease to pravastatin ( 40 mg per day ; n=2891 ) or placebo ( n=2913 ) . Baseline cholesterol concentrations ranged from 4.0 mmol/L to 9.0 mmol/L. Follow-up was 3.2 years on average and our primary endpoint was a composite of coronary death , non-fatal myocardial infa rct ion , and fatal or non-fatal stroke . Analysis was by intention-to-treat . FINDINGS Pravastatin lowered LDL cholesterol concentrations by 34 % and reduced the incidence of the primary endpoint to 408 events compared with 473 on placebo ( hazard ratio 0.85 , 95 % CI 0.74 - 0.97 , p=0.014 ) . Coronary heart disease death and non-fatal myocardial infa rct ion risk was also reduced ( 0.81 , 0.69 - 0.94 , p=0.006 ) . Stroke risk was unaffected ( 1.03 , 0.81 - 1.31 , p=0.8 ) , but the hazard ratio for transient ischaemic attack was 0.75 ( 0.55 - 1.00 , p=0.051 ) . New cancer diagnoses were more frequent on pravastatin than on placebo ( 1.25 , 1.04 - 1.51 , p=0.020 ) . However , incorporation of this finding in a meta- analysis of all pravastatin and all statin trials showed no overall increase in risk . Mortality from coronary disease fell by 24 % ( p=0.043 ) in the pravastatin group . Pravastatin had no significant effect on cognitive function or disability . INTERPRETATION Pravastatin given for 3 years reduced the risk of coronary disease in elderly individuals . PROSPER therefore extends to elderly individuals the treatment strategy currently used in middle aged people
