2. INTRODUCTION
Earliest trials of lipid lowering with bile acid sequestrants
In 1971, Akira Endo, a Japanese reasoned that certain microorganisms
may produce inhibitors of HMG CoA enzyme to defend themselves, as
mevalonate is a precursor of many substances required by organisms for
the maintenance of cell wall or cytoskeleton.
The first agent they identified was mevastatin (ML-236B), a molecule
produced by the fungus Penicillium citrinum.
Mevastatin was never marketed, because of its adverse effects of tumors,
muscle deterioration, and sometimes death in laboratory dogs.
By 1978, Merck had isolated lovastatin (mevinolin, MK803) from the
fungus Aspergillus terreus first marketed in 1987 as Mevacor.

META ANALYSIS OF STATINS IN STROKE
Statins is not associated with an increase in haemorrhagic stroke
Statins reduce the incidence of stroke in high-risk populations (mainly patients with
coronary heart disease, diabetes, or hypertension) even with a normal baseline cholesterol
concentration.
Whether they actually reduce the incidence of recurrent strokes in secondary prevention is
unproved.

IMPROVED REDUCTION OF OUTCOMES: VYTORIN EFFICACY INTERNATIONAL TRIAL
• A multicenter, double-blind, randomized study to establish the
clinical benefit and safety of vytorin (ezetimibe/simvastatin
tablet) vs simvastatin monotherapy in high-risk subjects
presenting with acute coronary syndrome
• Primary Outcome Measures: death due to any cardiovascular
events, non-fatal coronary events, and non-fatal strokes
• Time Frame: Trial will continue until a minimum of 5,250
subjects have a primary endpoint event and each subject is
followed for a minimum of 2.5 years
• Enrollment: 18141 Study
• Start Date: October 2005
• Estimated Study Completion Date: June 2013

(N = 1018). THIS INCLUDED 301( COL + METFORMIN TRIAL,)280 (COL + INSULIN TRIAL),
AND 437 (COL + SULFONYLUREA TRIAL.
Three double-blind, placebo-controlled trials in T2DM have now
independently confi rmed the HbA1c and LDL-C reductions with
COL.
In each of the primary studies, a significant mean treatment
difference in HbA1c (−0.54%, −0.50%, and −0.54%) and LDL-C
(−15.9%, −12.8%, and −16.7%) resulted from the addition of 3.75
grams/day of COL to existing metformin, insulin, or sulfonylureabased therapy, respectively,
TG (15%)and APOA I increased and HDL was constant.

111. TAKE HOME MESSAGE
In coronary artery disease ,stroke,perioperative morbidity the role
of statins is unquestionable
Role of statins in heart failure, aortic stenosis, and atrial
fibrillation needs further evaluation.
Ezetimibe lowers cholesterol but not the primary end points
Niacin are rather underused.
CETP inhibitors are not recommended(as of now)
Notas del editor
there was early separation of the primary event curves. A post-hoc analysis showed that the reduction in MCEs was statistically significant within 6 months of randomization with rosuvastatin treatment (HR 0.62; 95% CI 0.40, 0.96; p=0.029). This significant treatment difference was continued throughout the trial.
Ischemic events occurred only in 13% in atorvastatingp when compared to 21% in the angioplasty gp.. A significant diference of 36%This was one trial that showed that in low risk pts with svd /dvd high dose statin even better than revascularisation. It Can delay or prevent the need for percutaneous revascularization.
There was a strong trend toward the reduction of major coronary event by 11% in high dose statin
Similarly there was 16% less relative reduction in high dose statin gp in the secondary outcomes (any coronary heart ds or any cardiovascular disease)
IN THE POST CABGS TRIAL , post bypass patients were randomised to receive either high dose statins with Lovastatin or the moderarate treatment and followed for 7.5 YRS
The primary endpoint occurred in 3.7% of pts treated with statin reload and in the 9.4% in the placebo arm; this difference is mostly driven by reduction in periprocedural myocardial infarction
Similar to REVERSAL trial, the ARBITER trial showed significant reduction of Carotid intima medial thickness with 80 mg of atrovastatin compared to 40 mg of pravastatin
In a metaanalysis of 18, 000 pts enrolled in various trials, the safety of the high dose of atorvastatin was conclusively established with an overall incidence of hepatic enzyme elevation of 1.43%, and only 4 patients with creatine kinase elevations 10 times the upper limit of normal
