Treatment Guidelines
“Intensity Of Statin Therapy”
Aim to Reduce RISK … not at Target levels
DR.PRAVEEN NAGULA
Scope of guideline
• to reduce atherosclerotic cardiovascular disease(ASCVD)risk
{RCTs,systematic analysis and metaanalysis of RCTs}.
• ASCVD – coronary heart disease(CHD),stroke,and
peripheral arterial disease,all of presumed atherosclerotic
origin.
• to provide strong evidence-based foundation.
• only evidence from statin RCTs were used to develop
guidelines.****
• Comprehensive approach to lipid management for purposes
with relation to ASCVD reduction only,not for complex lipid
disorders.
What do present guidelines
say.....
Patient centered approach
rather than
one treatment fits all
What’s new in the guideline…?
Benefits of Statins
• High intensity therapy – lowering LDL cholesterol by >50%.
• Moderate intensity therapy - lowering LDL cholesterol by 30-50%.
• Reduces ASCVD events across the spectrum of baseline LDL-C
levels > 70 mg/dl.
• Relative reduction in ASCVD risk is consistent for primary and
secondary prevention.
 Absolute reduction in ASCVD events is proportional to baseline
absolute ASCVD risk.
 Statin therapy only for individuals at increased ASCVD risk .
Who are to be benefited
by Statins ?????
Primary prevention of ASCVD
• Based on the estimated absolute 10 yr risk of ASCVD
(non fatal MI,CHD death,nonfatal and fatal stroke)…
• The omnibus CV risk calculator for
 Pts without clinical ASCVD and LDL 70-189mg/dl
Estimates 10 yr risk of ASCVD
 In diabetics ,for primary prevention
Not in pts with clinical ASCVD

Basis for the New Guidelines
 RCTs reviewed showed a consistent reduction in ASCVD
events from Statins therapy in secondary and primary
prevention, no ASCVD event reduction in those with NYHA
class II-IV HF or receiving maintenance hemodialysis.
 Only fixed doses of statins with placebo or untreated
controls,comparison of high dose with moderate intensity
statins.
 No evaluation of the effect of titrated (dose adjusted) statin
treatment to achieve prespecified LDL- C or non HDL-C
goals.
 Use of niacin to additionally lower non HDL –C,once an LDL
target was achieved,did not further reduce ASCVD
outcomes.(AIM HIGH trial)
 The intensity of statin therapy is appropriate on those most
likely to benefit.
• Rosuvastatin to prevent vascular events in men and women with elevated C-reactive protein. N Engl J Med 2008;359:2195-207
• AFCAPS-TEXCAPS, JAMA 1998;279:1615–1622
• MEGA trial, Lancet 2006;368:1155–1163.
3 CQs –
CQ1 -
secondary,(19RCT)
CQ2 – primary
prevention (6RCT)
CQ3 – comprehensive
management,safety of
each drug
Why other approaches
ignored???
 1.Treat to Target – widely used for past 15 yrs
What is the target ?
What is the additional risk reduction beyond one target lower
than other?
adverse effects from multidrug therapy that occur in achieving
goal
undertreatment with statins, overtreatment with nonstatins
 2.lowest is best
adverse effects?
 3.lifetime risk
long term follow up >15 yrs?
statins>10yrs?
Why Target level therapy
ignored..how came the picture of
statin benefit groups?
Hypothesis or Evidence based..
Myth or reality
A.Secondary Prevention
 Evidence – high intenisty therapy to maximally lower LDL –C than
using a target.
 Ex – LDL –C 78mg/dl on a dose of atorvas 80 mg/dl –receiving EBT.
 No data to show that adding a nonstatin drug to high intenisty statin
therapy will provide incremental ASCVD risk reduction benefit with
acceptable margin of safety.(AIM HIGH,ACCORD).
 This patient may be exposed to adverse effects if started of a drug with
no evidence of benefit,just because his LDLis more than arbitrarily
level.
 This is treated as a case of failure..for a lag of 8 mg/dl..Is it justifiable
???
AIM HIGH trial NewEngl J Med 2011;365:2255-67
ACCORD, N Engl J Med 2010;362:1563–74.
B.FH with LDL –C >190 mg/dl
 many does not achieve <100mg/dl.
 maximum may be 120 mg/dl on 3 drugs.
 These pts may have fallen short of target ,but their LDL –C 
>50% ,more ASCVD risk reduction.
 Not treatment failures.
C.Type2Diabetes :
 have lower LDL-C than with without diabetes.
 goal directed therapy encourages low statin doses,use of drugs
for addressing HDL-C/high TG.
 maximally tolerated therapy to be given primary importance.
D.Estimated ASCVD >7.5%

Taylor F, Ward K, Moore TH et al. 2011:CD004816
Limitations
• Clinical judgement required in pts,for whom RCT evidence is
insufficient
• Younger adults< 40 yrs with <7.5% ASCVD risk for 10
yrs,high lifetime risk.
• HIV pts,rheumatological pts,IBD pts.
• RCTS,Systematic reviews,meta analysis of RCTs were taken
into consideration.
New Drugs
• Cholesterol ester transfer protein (CETP) inhibitors -
Anacetrapib(DEFINE,REVEAL), dalcetrapib
• Ab to pro-protein convertase subtilisin/kexin 9 (PCSK9).
• Apolipoprotein B synthesis inhibitors - Mipomersen
• Microsomal triglyceride transfer protein (MTP) inhibitors,
• Thyroid hormone analogue Eprotirome
Future..
 Primary prevention in >75 yrs age
 Alternate treatment strategies.
 Effectiveness of submaximal doses of statins vs nonstatins in
intolerant pts
 Evaluation of the incidence of new onset diabetes associated
with statin therapy.
 Outcomes of RCTs of new lipid modifying agents to determine
the incremental ASCVD reduction when added to statin
therapy.
Future updates required for..
 1.The treatment of Hypertriglyceridemia.
 2.Use of NonHDL-C in decision making.
 3.Whether on-treatment markers such as
apoB,Lp(a),LDLparticles are useful in guiding decisions.
 4.Best approaches to use noninvasive imaging for refining
risk estimates to guide treatment.
 5.Optimal age for starting treatment for reducing lifetime risk
of ASCVD.
 6.What to do in pts with HF,hemodialysis.
 7.Long term effects of statin associated new onset diabetes and
management.
Conclusions
 Patient centered approach is to be given importance rather than
one treatment fits all concept.
 Statins to be given at high intenisty,moderate intensity doses but not
with target levels of attainment.
 Nonstatins give no ASCVD benefit in pts with high intensity statin
therapy.
 Use of lipoprotein a ,non HDLcholesterol levels assessment is not
recommended.
 Pts without ASCVD should be started of the statins after assessing 10 yr
risk by omnibus calculators.
 New onset diabetes due to statins needs further assessment in future.
 New drugs in pipeline,RCT s required for their incremental benefit in
ASCVD risk reduction when added to statins
 Lifestyle modification remains the key concept of the management of
blood cholesterol.
