Efficacy of statins in primary and secondary prevention of CV events - well established Meta-analyses of RCTs : - demonstrated dramatic reductions in major CV events, cardiovascular morbidity, and all-cause mortality

LDLC ↓ - reduces initial coronary events - reduces recurrent coronary events - decreases stroke - Slows progression of atherosclerosis - induce regression of atherosclerosis

- A 1% reduction in LDL-C reduces coronary events by 1%- High dose of statins→ reduces LDL-C levels and coronary events by 50%.

Compared the outcome of aggressive lipid-lowering with atorvastatin (80 mg/day) to that of angioplasty in 341 patients with 1 or 2 vessel CAD and LDL levels >115 mg/dl

18 month follow-up : - reduction in mean LDL levels was greater in the atorvastatin group - (140 to 77 mg/dL V/S 140 to 119 mg/dL in the angioplasty group)

- Atorvastatin group :- Insignificant trend toward fewer composite endpoints

(13 v/s 21 percent )- lower rate of CABG (1.2 v/s 5.1 percent) - hospitalization for worsening angina (6.7 versus 14.1 percent)

Statins may decrease CVS events by a number of mechanisms( important early after MI)

- plaque stabilization- reversal of endothelial dysfunction- inhibition of monocyte recruitment

- ↓ed thrombogenicity- reduction in inflammation

Early use of statins after an ACS

Secondary prevention trials : - primarily evaluated the role of statin therapy initiated 3 to 6 months or longer after acute MI

- led to the investigation of earlier initiation of statin therapy during ACS (MI or unstable angina)

Effects of Atorvastatin on Early Recurrent Ischemic Events in ACS: A Randomized Controlled Trial

Myocardial Ischemia Reduction with Aggressive Cholesterol Lowering (MIRACL)

Objective:

“To prove that early, rapid, and intensive cholesterol lowering therapy will reduce early recurrent ischemic events in patients with unstable angina or

non-Q-wave MI”

The Hypothesis

Rapid and early cholesterol reduction

Early plaque stabilisation

Diminished incidence of recurrent ischemic

events

Trial design: This study evaluated the efficacy of an atorvastatin reloading strategy in patients on chronic statin therapy undergoing PCI for stable angina or NSTEMI.

Results

Conclusions

• An 80 mg loading dose of atorvastatin followed by a 40 mg preprocedural dose may reduce the incidence of post-procedure MACE in patients on background statin therapy

• These data support a strategy of routine atorvastatin reloading prior to PCI in patients on background statin therapy

Meta-analysis of Statin Use in HF

- Meta-analysis of 13 HF trials estimated survival benefit of statin use in patients with HF of ischemic and nonischemic etiologies

- Statin use in HF associated with 26% RRR in mortality (HR 0.74; 95% CI, 0.68 to 0.8)

8 trials - statin use associated with an improved survival among patients who had HF

- Effect is noted independent of etiology for HF (for ischemic etiology HR 0.73; 95% CI 0.65 to 0.82) ( for nonischemic etiology HR 0.73; 95% CI 0.61 to 0.87)
