Statins for Secondary Prevention
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%.
- Statins in Stable CAD
- Intensive Statin therapy
- Statins in Acute Coronary Syndromes
- Statin therapy before PCI

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)
Time to the first ischemic event was significantly longer in the atorvastatin group compared with the placebo group
Non significant trend toward fewer cardiac
events (13 versus 21%).

Relationship between LDL-C Levels and Event Rates in Secondary Prevention Statin Trials of Patients with Stable CHD
CHD event rates in secondary prevention trials (5 years in duration except the PROVE-IT study, which lasted 2 years) were directly proportional to low-density lipoprotein (LDL) cholesterol levels. The event rate is predicted to approach 0 at LDL of 30 mg/dL

SATURN trial - Compared two intensive statin therapy regimens - Atorvastatin 80 mg daily v/s Rosuvastatin 40 mg daily- 1039 patients with known CAD
- No statistically-significant difference between the regimens in the primary endpoint of percent atheroma volume (↓ed with both regimens : 1.22 % V/S 0.99 % respectively)
Compared with Atorvastatin patients treated with Rosuvastatin had- lower levels of LDL-C 62 md/dl v/s 70.2 mg/dL
- higher levels of HDL-C 50 mg/dl v/s 48.6 mg/dL
- Statins in Stable CAD
- Intensive Statin therapy
- Statins in Acute Coronary Syndromes
- Statin therapy before PCI
- Statins in Heart Failure
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)

- Prospective, multicenter, randomized, open-label, 3-arm, parallel-group trial.
Inclusion Criteria:1. ACS patients with in 48 hrs of ischemia - STEMI pts with intervention with in 12 hrs of symptoms (TLT or PCI) - NSTEMI/UA with conservative management - LDL-C >70 mg/dl, fasting TG < 500 mg/dl with in 72 hrs of symptom onset
Baseline characteristics of randomized

* p <0.05; † p < 0.01; ‡ p < 0.001 versus atorvastatin 80 mg/day.
Mean percent change from baseline by weeks 2, 6, and 12 in low-density lipoprotein cholesterol (LDL-C)
Mean percent change from baseline by weeks 2, 6, and 12 in (high-density lipoprotein cholesterol (HDL-C)..
Conclusion: LUNAR study
RSV 40 more effectively decreased LDL-C , increased HDL-C and improved other blood lipid parameters when compared to RSV20 And ATV80 in patients with ACS

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

causes, number of hospitalizations.
No significant risk reduction in primary outcome- death from CVS causes - nonfatal MI - nonfatal stroke
CORONA Trial:Controlled Rosuvastatin in Multinational Trial in HF
N Engl J Med 2007;357:2252
- No effect on CVS outcome, NYHA class or quality of life.
- Fewer hospitalizations for CVS causes ( Rosuvastatin (2193) v/s placebo (n 2564) (P < .001)
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)
Meta-analysis of mortality among patients with heart failure HF patients using statins (n = 30,107) HF patients not using statins (n =101,323)
J Am Coll Cardiol 2008;51:422
(A) Adjusted mortality among patients with ischemic HF (n = 62,273) using statins, compared with those not using statins (B) Mortality among patients with HF of nonischemic HF (n 5 31,551) using statins
compared with those not using statins.
