1 Statinai ir širdies nepakankamumas: naujausi mokslo įrodymai
Aušra Kavoliūnienė KMU docentė KMUK Kardiologijos klinikos II skyriaus vadovė 2008m.

2 STATINAI Labai daug pozityvių RKT įrodyti statinų įtakai ŠKL baigčių (ŪMI, KA, insultas) pagerinimui Vaistų klasė kilusi iš natūraliosios medicinos – žolinių vaistų , t.y. raudonųjų grybelių , augančių ant ryžių (red yeast rice), kurie pasižymi savybe mažinti cholesterolio koncentraciją Trys iš statinų yra tiesioginiai natūralūs produktai: pravastatinas, simvastatinas ir lovastatinas, kiti gi yra sintetiniai produktai.

3 Statinai gydant lėtinį ŠN
Potenciali nauda: Išemijos komplikacijų sumažinimas Pleiotropinis (priklausomas ne nuo cholesterolio sumažinimo) poveikis Potencialūs nepageidautini reiškiniai Ubichinono hipotezė Endotoksinų hipotezė

8 Class effects of statins in elderly patients with congestive heart failure: A population-based analysis Background Long-term treatment with statins reduces mortality in patients with congestive heart failure (CHF). Whether statin agents exert a class effect is unknown. Methods We analyzed long-term mortality in Canadian patients aged ≥65 years who were discharged from hospital with a diagnosis of CHF from January 1998 to December Administrative data from Quebec, Ontario, and British Columbia were merged. We compared patients prescribed with atorvastatin, simvastatin, pravastatin, and lovastatin. Results A total of patients hospitalized with a diagnosis of CHF fulfilled the inclusion criteria for this study. In this final dataset, 6670 (43.4%) filled a prescription for atorvastatin, 4261 (27.7%) for simvastatin, 3209 (20.9%) for pravastatin, and 1228 (8.0%) for lovastatin. Clinical characteristics and proportion of days covered with a statin prescription were similar across groups. Drug dosages were relatively low, with 82% of patients who received the agent at a dose of ≤20 mg. Although controlling for time-dependent covariates representing current use and dosage, as well as for age, sex, coronary artery disease, and several other comorbidities, treatment with pravastatin (adjusted hazards ratio [HR] 0.94, 95% CI ), lovastatin (adjusted HR 1.02, 95% CI ), or simvastatin (adjusted HR 0.92, 95% CI ) had a similar effectiveness to prevent mortality compared to atorvastatin (reference in this analysis) in this population with CHF. Time dependent exposure to a statin was highly protective against mortality. Conclusions Statins exert a class effect in patients with CHF, when used at a relatively low dose. The favorable effects appear largely independent of drug dosage. (Am Heart J 2008;155: )

Rosuvastatin 20 mg produced an additional 6% LDL-C reduction, and rosuvastatin 40 mg produced an additional 3% LDL-C reduction.1 Additional Background Information: This 6-week, parallel-group, open-label, randomized, multicenter trial compared rosuvastatin with atorvastatin, pravastatin, and simvastatin across dose ranges for reduction in LDL-C.1 After a dietary lead-in period, 2,431 adults with LDL-C 160 and <250 mg/dL and TG <400 mg/dL were randomized to treatment with rosuvastatin 10, 20, 40, or 80 mg; atorvastatin 10, 20, 40, or 80 mg; simvastatin 10, 20, 40, or 80 mg; or pravastatin 10, 20, or 40 mg.1 Atorvastatin 10 mg, rosuvastatin 10 mg, and simvastatin 10 mg produced reductions in LDL-C of 37%, 46%, and 28%, respectively.1 Rosuvastatin 20 mg and 40 mg produced additional reductions in LDL-C of 6% and 3%, respectively (actual percent reductions of 52% and 55%, respectively).1 Atorvastatin 20 mg, 40 mg, and 80 mg produced additional reductions in LDL-C of 6%, 5%, and 3%, respectively (actual percent reductions of 43%, 48%, and 51%, respectively).1 Simvastatin 20 mg, 40 mg, and 80 mg produced additional reductions in LDL-C of 7%, 4%, and 7%, respectively (actual percent reductions of 35%, 39%, and 46%, respectively).1 Mean baseline LDL-C levels were 187 mg/dL to 194 mg/dL across treatment groups.

35 Treating to New Targets (TNT) Study
The TNT hypothesis was tested in a double-blind, parallel-group design. A total of 18,469 patients were screened; lipid-lowering therapy was withdrawn, and all patients entered a wash-out phase. 15,464 patients with established CHD and an LDL-C level of 130 to 250 mg/dL (3.4 to 6.5 mmol/L) and with triglycerides 600 mg/dL (6.8 mmol/L) were then eligible to enter the 8-week, open-label, run-in period with atorvastatin 10 mg/day. In order that the 2 groups of patients would meet the LDL-C targets during the double-blind phase—and because it would have been unethical to under-treat patients whose LDL-C remained >130 mg/day (>3.4 mmol/L)—only those patients with a mean LDL-C <130 mg/dL (<3.4 mmol/L) on 10 mg of open-label atorvastatin were entered into the randomized phase of the study. 10,001 patients were randomized to double-blind therapy with either atorvastatin 10 mg/day or 80 mg/day; 5006 patients remained on atorvastatin 10 mg daily and 4995 patients received 80 mg daily. Using the time of randomization as the baseline for the study, patients were then followed for a median of 4.9 years. Reference 1. LaRosa JC, et al. N Engl J Med. 2005;352. Slide 36

36 Treating to New Targets (TNT) Study
Patients were eligible for inclusion in the study if they satisfied the following criteria: Men and women aged years. Clinically evident CHD, defined as previous MI, previous or present angina with objective evidence of atherosclerotic CHD, or patients who have undergone a coronary revascularization procedure. LDL-C mg/dL ( mmol/L) and triglycerides 600 mg/dL (6.8 mmol/L ) at the beginning of the open-label, run-in period. LDL-C <130 mg/dL (<3.4 mmol/L) at the end of the open-label, run-in period. Reference 1. Waters DD, et al. Am J Cardiol. 2004;93:154-8. Slide 37

37 Treating to New Targets (TNT) Study
Major exclusion criteria included any of the following: Hypersensitivity to statins. Active liver disease or hepatic dysfunction, defined as ALT or AST 1.5  the upper limit of normal. Patients with nephrotic syndrome. Women who are pregnant or breastfeeding. Uncontrolled diabetes mellitus, hypothyroidism, or hypertension (as defined by the investigator) at the screening visit. MI, coronary revascularization procedure, or severe/unstable angina within 1 month of screening. Ejection fraction <30%. Unexplained CPK levels >6 times the upper limit of normal. Non-skin malignancy, malignant melanoma, or other survival-limiting disease. Concurrent therapy with long-term immunosuppressants, or lipid-regulating drugs not specified as study treatment in the protocol. Any planned surgical procedure for the treatment of atherosclerosis. Hemodynamically important valvular disease. Gastrointestinal disease limiting drug absorption or partial ileal bypass. History of alcohol abuse. Participation in another clinical trial concurrently or within 30 days before screening. Reference 1. Waters DD, et al. Am J Cardiol. 2004;93:154-8. Slide 38

38 Treating to New Targets (TNT) Study
The primary efficacy outcome measure was the time to occurrence of a major cardiovascular event, defined as: CHD death. Nonfatal, non–procedure-related MI. Resuscitated cardiac arrest. Fatal or nonfatal stroke. Reference 1. LaRosa JC, et al. N Engl J Med. 2005;352. Slide 39

39 Treating to New Targets (TNT) Study
Over the course of the study, there was a highly significant reduction in the composite efficacy outcome of major cardiovascular events (death from CHD, nonfatal non–procedure-related MI, resuscitated cardiac arrest, or fatal or nonfatal stroke) in the atorvastatin 80 mg group compared with the atorvastatin 10 mg group. The Kaplan-Meier analysis demonstrated a hazard ratio of 0.78 (95% CI 0.69, 0.89; P<0.001). This represented a 22% reduction in relative risk in the atorvastatin 80 mg group relative to the atorvastatin 10 mg group, over and above the low absolute event rate of 10.9% recorded in the atorvastatin 10 mg group. There was no statistical interaction for age or gender in the primary outcome measure. Reference 1. LaRosa JC, et al. N Engl J Med. 2005;352. Slide 40

40 Treating to New Targets (TNT) Study
Because of the potential for severe long-term physical and mental disability, stroke can be a huge economic burden on society. Reduction of LDL-C substantially below 100 mg/dL (2.6 mmol/L) with atorvastatin 80 mg also provided significant clinical benefit beyond the coronary vasculature, reducing the risk of stroke by 25% (P=0.02). Reference 1. LaRosa JC, et al. N Engl J Med. 2005;352. Slide 41

41 Treating to New Targets (TNT) Study
A relative reduction in the risk of the secondary efficacy outcome major coronary events (CHD death, nonfatal non–procedure-related MI, resuscitated cardiac arrest) was observed with atorvastatin 80 mg compared with atorvastatin 10 mg (HR = 0.80; 95% CI 0.69, 0.92; P=0.002). Reference 1. LaRosa JC, et al. N Engl J Med. 2005;352. Slide 42

42 Treating to New Targets (TNT) Study
Relative reductions in the secondary outcome measures of any cardiovascular event (19%), major coronary event (20%), any coronary event (21%), cerebrovascular event (23%), and hospitalization with a primary diagnosis of CHF (26%) with atorvastatin 80 mg compared with atorvastatin 10 mg were all consistent with the reduction observed for the primary composite outcome. The effect of atorvastatin 80 mg on the risk of PAD did not differ significantly from that of atorvastatin 10 mg (HR = 0.97; 95% CI 0.83, 1.15; P=0.76). Reference 1. LaRosa JC, et al. N Engl J Med. 2005;352. Slide 43

43 Treating to New Targets (TNT) Study
A relative reduction in the risk of nonfatal MI or CHD death was also observed with atorvastatin 80 mg compared with atorvastatin 10 mg (HR = 0.78; 95% CI 0.68, 0.91; P<0.001). Reference 1. LaRosa JC, et al. N Engl J Med. 2005;352. Slide 44

44 Treating to New Targets (TNT) Study
Evaluation of individual components of the primary and secondary efficacy outcome measures showed that treatment with atorvastatin 80 mg had a consistent and significant beneficial effect on most measures of coronary morbidity, including nonfatal non–procedure-related MI, fatal or nonfatal stroke, any cardiovascular event, major coronary events, all coronary events, cerebrovascular events, and hospitalizations with primary diagnosis of CHF.

CARE tyrimas (706 lig. Su KSIF <40 bet >25) pravastatinas buvo vienodai veiksmingas mažinant VA ligą lyginant su lig, kurių KSIF > 40 The Scandinavian Simvastatin Survival Study (4S) reported a 19.6% long-term reduction in the development of HF in patients with a history of myocardial infarction randomized to statin therapy.28 Among patients diagnosed with HF, 10.3% were on placebo and 8.3% were on simvastatin. Baseline lipoprotein characteristics and changes in lipoproteins after 1 year of treatment were similar in patients who developed HF and those who did not develop HF. This finding could be explained by the pleiotropic effects of simvastatin. Similarly, retrospective analysis of the Evaluation of Losartan in the Elderly Study (ELITE II) showed patients with symptomatic HF treated with statins had lower mortality—10.6% vs. 17.6% A retrospective analysis in the Prospective Randomized Amlodipine Survival Evaluation trial (PRAISE) showed that there was a 42% reduction in mortality in patients on statins compared with nonstatin users over a period of 1.3 years in 134 patients. Adjusting for age, gender, diabetes, smoking, HF etiology, EF, New York Heart Association (NYHA) class, statin therapy was associated with a 62% lower risk of death (HR 0.38; 95% CI 0.23–0.65).30 This was irrespective of etiology of ischemic versus nonischemic. The GREek Atorvastatin and Coronary heart disease Evaluation (GREACE) trial recently investigated the effects of atorvastatin on several primary cardiovascular endpoints including HF in patients with established CAD. This study reported a reduction in HF from 2.7% to 13% in years of follow-up (relative risk 0.55) in the atorvastatin-treated group compared with usual medical care.31 Statins have also shown to improve survival in patients with diastolic HF. In a recent small series of patients, treatment with atorvastatin, simvastatin, pravastatin, or fluvastatin increased survival rates were noted irrespective of the LDL cholesterol levels (relative risk of death [95% CI] 0.22 [0.07–0.64]; P = .006).32 After baseline adjustment for differences among groups (hypertension, diabetes, CAD, and serum creatinine), statin therapy was associated with lower mortality. Using propensity matching, statin therapy was associated a trend toward improved survival without cardiovascular hospitalization (log rank 3.02; P = .082).32

59 A retrospective study by Horwich and colleagues showed statin therapy was associated with improved survival without the necessity for urgent transplantation in both ischemic and nonischemic HF. On a cohort of 551 patients with systolic HF (EF <40%), 45% were receiving statin therapy. This was associated with improved survival in both ischemic and nonischemic HF (81 vs. 63% P < .001; 91 vs. 72% P < .001) at 1-year follow-up. Adjusting risk for age, gender, CAD, cholesterol, diabetes, medications, hemoglobin, creatinine, and NYHA functional heart class, statin therapy remained an independent predictor of improved survival (HR 0.41; 95% CI 0.18–0.94).33 T he Optimal Trial in Myocardial Infarction with Angiotensin II antagonist Losartan (OPTIMAAL) compared the Ang-II receptor antagonist losartan with angiotensin-converting enzyme inhibitor captopril on mortality and morbidity in patients with evidence of HF or left ventricular dysfunction in the acute phase after acute myocardial infarction. Analysis of all-cause mortality unadjusted for baseline differences showed that treatment with statins alone was associated with a relative risk reduction of 55.2% (P < .001). The effects of combined statin and β-blockers appeared to be additive with a relative risk reduction of 72.7% (P < .001) compared with no treatment. After adjustment for risk variables before inclusion, statin treatment alone was associated with a reduction of 26.1%; combination was associated with a decrease of 48.3% compared with no treatment.34 A post hoc analysis of 5010 patients enrolled in the VALsartan Heart Failure Trial (Val-Heft), 1602 of whom were taking statins, showed the mortality rate over a 2-year period was 17.9% for patients on statins compared with 20.3% for patients not on statins (P = .029) Similarly, the Cardiac Insufficiency BIsoprolol study (CIBIS) II included 2647 patients with ischemic and nonischemic cardiomyopathy who were randomized to receive bisoprolol or placebo. A total of 226 patients or 8.5% were receiving statins during baseline. This was associated with an improved survival benefit (P < .005).36

60 Prieštaringi požiūriai į statinų vartojimą gydyti ŠN
Didesnė BCh ir MTL-Ch koncentracija – gerenis išgyvenamumas sergant ŠN, nepriklausomai nuo etiologijos, amžiaus, KSIF, fizinio pajėgumo 39 Maža serumo cholesterolio koncentracija yra nepriklausomai susijusi su blogesne ŠN prognoze. Statinai mažina dviejų veiksnių – ubichinono ir lipopolisaccharidų (LPS) koncentraciją, kurie apsaugo nuo ŠN progresavimo. Ubichinonas (kofermentas Q10) , priklauso nuo HMG-CoA reduktazės, jį mažina statinai. Ubichinonas, kaip maisto paildas, gerina ŠN simptomus41 . Kofermentas Q10 dalyvauja mitochondrijų fosforilinimo procese ir dalyvauja ATF gamyboje. Jis pasižymi antioksidaciniu ir membranas stabilizuojančiu poveikiu42 Endotoksinai, tokie kaip LPS, gali greitinti ŠN progresavimą per uždegiminius citokinus. LPS koncentracija yra didesnė sergant ŠN. Plazmos lipoproteinai surišą endotoksinus, o gydymas statinais mažina lipoprotrinus ir jų detoksikuojantį poveikį. 39 Hedrich O et al.
