5. What are target levels for treatment and prevention? Total cholesterol target levels is the part of patient common absolutely risk appraisal. The real objective is a LDL-C target levels. Both European and American guidelines define low levels of LDL-C (<1,8 mmol / l) as the primary goal of therapy in patients with established coronary artery disease or equivalent risk

Very high risk Documented CVD by invasive or non-invasive testing (such as coronary angiography, stress echocardiography, carotid plaque on ultrasound), previous myocardial infarction(MI), ACS, coronary revascularization and other arterial revascularization procedures, ischemic stroke, PAD. Patients with type 2 diabetes, patients with type 1 diabetes with target organ damage (such as microalbuminuria). Patients with moderate to severe CKD (GFR-6mL/min/1.73m2).

Moderate risk Subjects are considered to be at moderate risk when their SCORE is ≥1% and,5% at 10 years. Many middle-aged subjects belong to this risk category. This risk is further modulated by a family history of premature CAD, abdominal obesity, physical activity pattern and social class. < 3.0 mmol/L < 4,5 mmol/L>1.0 mmol/L за жени >1,2 mmol/L за мъже < 1.7 mmol/L 4.

20. Aggressive statins therapy: A meta analysis Meta-analysis of 26 randomized trials (21 statin trials versus placebo and 5 trials of intensive statin against the standard dose), 170 000 patients which is published 2010. In summary: 1 mmol/l reduction in LDL-C with statin drug therapy lead to 20% reduction of vascular events (coronary death, nonfatal MI, coronary revascularization, and death) High doses of statins lead to additional lowering of LDL-C by an average of 0,51 mmol/l = 15% additional reduction in major vascular events, 13% in coronary mortality and nonfatal MI, 19% of the needs of coronary revascularization and 16% of ischemic stroke Effect (intensive dose) on cardiovascular events is significant in the first year - 12% reduction and increases with increasing time of administration of statin therapy - ~ 28% reduction for subsequent years (5.1 years) *Treatment Trialists’ (CTT) Collaborators.

32. SIMVASTATIN: Main conclusions After allowance for non-compliance, 40mg daily simvastatin safely reduces the risk of heart attack, of stroke, and of revascularisation by about one-third 5 years of statin treatment typically prevents these “major vascular events” in about: 100 of every 1000 people with previous MI 80 " " " other CHD 70 " " " cerebrovascular disease 70 " " " other arterial disease 70 " " " diabetes (age 40+)....irrespective of cholesterol level (or age, or sex, or other treatments)

33. Evidences for Primary prevention  ASCOT (Anglo-Scandinavian Cardiac Outcomes Trial) - clinical benefit of atorvastatin 10 mg / day versus placebo in total 10 305 hypertensive patients with average total cholesterol 5.5 mmol / L, mean levels of LDL-C 3.4 mmol / L and high risk profile. Originally planned for a 5-year follow-up study ASCOT was prematurely terminated due to the obvious benefits. Treatment with atorvastatin decreased the relative risk of cardiovascular events by 36% (P = 0.0005) and stroke - with 27% (P = 0.024). No effect on mortality or differences in the incidence of side effects in different groups.  CARDS (The Collaborative Atorvastatin Diabetes Study) - prevention of CVD and CVD (acute coronary events and stroke), featuring high-risk patients with type 2 diabetes and at least one risk factor, but not with elevated levels of cholesterol  Due to the proven clinical benefits for patients treated with atorvastatin 10 mg daily compared with placebo the study was discontinued in advance.  Reduced the relative risk of: stroke - 41%, acute coronary events - 36%, coronary revascularization - 31%

36. CARDS: The Collaborative Atorvastatin Diabetes Study - Results-

38. CARDS: The Collaborative Atorvastatin Diabetes Study - Summary - Compared with placebo, patients receiving 10 mg atorvastatin daily showed a 37% reduction in major cardiovascular events from 9.0% to 5.8 % (p = 0.001) There was a favourable trend in the atorvastatin group with regard to all cause mortality, acute coronary events, coronary revascularization, and stroke Adverse event rate similar in atorvastatin and placebo groups. No cases of rhabdomyolysis.

39. MIRACL (Myocardial Ischemia Reduction and Aggressive Cholesterol Lowering) – atorvastatin 80 mg versus placebo & PROVE-IT (atorvastatin 80 mg versus pravastatin 40 mg) studied the assumption that early treatment with high doses (80 mg daily) atorvastatin after ACS would have clinically significant benefits. TNT (Treating to New Targets) - maximum doses of atorvastatin (80 mg daily) decreased the mean LDL-C of about 2.6 to 2.0 mmol / L, and the incidence of serious cardiovascular events was reduced by 22% compared with the lower dose (10 mg daily) Evidences for Secondary prevention Summary: In patients with ACS, intensive lipid lowering therapy has a better protective effect (death and major CV events) compared with standard therapy.

47. The TNT study confirmed and extended the growing body of evidence indicating that lowering LDL cholesterol to values well below currently recommended levels with more intensive statin therapy is associated with additional cardiovascular benefit. The current sub-analysis of the TNT study indicates that these benefits are consistent in patients with diabetes and CHD. For secondary outcomes (any cardiovascular event, major coronary event (CHD death, nonfatal non procedure-related myocardial infarction, or resuscitated cardiac arrest), any coronary event, cerebrovascular event etc.), intensive therapy with atorvastatin 80 mg significantly reduced the rate of all cardiovascular events and cerebrovascular events compared with atorvastatin 10 mg. In 2005, the ADA updated its clinical practice recommendations for patients with diabetes and cardiovascular disease, noting that these individuals are at very high risk for subsequent clinical events. On the basis of randomized trials of moderate versus intensive lipid lowering in very-high-risk (albeit nondiabetic) populations, the ADA advised that use of high-dose statin to achieve an LDL cholesterol level of < 1,8 mmol/l was a therapeutic option in diabetic patients with cardiovascular disease TNT: Treating to New Targets Conclusions

53. According to evidence-based medicine…  The most important indicator for reducing cardiovascular risk is LDL-C  For the best control of high-risk patients (all patients with coronary artery disease,pateints after invasive procedures, diabetes or cerebrovascular disease) should achieve optimal levels of LDL-C  According to U.S. recommendations (ATP III) and European recommendations (ESC 2011), the optimal level of LDL-C was 1,8 mmol / l “LDL-C and HDL-C - Is their unique effect on atherosclerosis?” Ass.Prof. Ivo Petrov – Head of Cardiology clinic, Tokuda hospital Sofia.

54. Algorithm for treatment recommended by the ESC 2011 1. Assessment of total cardiovascular risk of patients 2. Involving patients in decisions about the management of cardiovascular risk 3. Identification of target LDL-C, depending on the level of risk 4. Calculate the percentage reduction in LDL-C, necessary to achieve target. 5. Choice of statin, which on average can provide this reduction. 6. Due to the response of statin treatment is different, increasing the dose until the target is mandatory! 7. If statins can not achieve the goal, consider drug combinations. Patient's clinical condition, concomitant drug treatment and tolerance will determine behavior in determining the final choice of medication and dosage.
