Detailed Lipid Profiles and Lipid-related Residual Risk after 12-week 10 mg Rosuvastatin Treatment for Acute Myocardial Infarction.

Objective We aimed to reveal detailed on-treatment lipid profiles, lipid-related surrogate markers, and factors predicting failure to achieve the guideline-recommended lipid management goal following guideline-recommended statin treatment in Japanese patients with acute myocardial infarction (AMI). Methods and Results Sixty AMI patients who underwent coronary intervention and had received rosuvastatin 10 mg/day since the start of their hospitalization were assessed for on-treatment lipid-related profiles, including high-sensitivity C-reactive protein, small dense low-density lipoprotein cholesterol (sd LDL-C), and lipoprotein (a), at the 12-week follow-up. Patients who failed to achieve the guideline-recommended lipid management at 12 weeks were defined as the "unachieved group." Univariate and multivariate logistic regression analyses were performed to evaluate the predictors of inclusion in the unachieved group after high-dose statin treatment. Despite the use of high-dose rosuvastatin, 61.7% of the enrolled AMI patients were included in the unachieved group. In addition, the unachieved group had higher sd LDL-C and lipoprotein (a) levels than the achieved group. Logistic regression analyses demonstrated that low baseline high-density lipoprotein cholesterol (HDL-C) levels and the absence of diabetes were predictors of inclusion in the unachieved group. Conclusion More than half of the Japanese AMI patients treated with rosuvastatin 10 mg/day did not achieve the guideline-recommended goal of lipid management and still had lipid-related residual risk at 12 weeks. Particular attention should be paid to patients with low baseline HDL-C levels and those without diabetes with regard to their on-treatment lipid profiles.

The high-dose statin treatment reduces neutrophil extracellular traps formation in patients with coronary artery disease

Abstract Background Neutrophil extracellular traps formation (NETosis) is currently considered as an important mediator in atherosclerosis and atherothrombosis. However, the impact of high-dose statin treatment, as potent cholesterol-lowering agents with pleiotropic effects, on NETosis in coronary artery disease (CAD) has been poorly described. Purpose We sought to assess whether in CAD patients the recommended statin treatment intensification is associated with changes in NETs-related markers and if such changes can alter fibrin clot properties. Methods 130 patients with advanced CAD, who did not achieve the target low-density lipoprotein cholesterol (LDL-C) were included. Before and at least 6 months after initiation of high-dose statin therapy (rosuvastatin 40 mg/d or atorvastatin 80 mg/d) citrullinated histone H3 (H3cit), myeloperoxidase (MPO) and neutrophil elastase (NE) as markers associated with NETosis were assessed in relation to C-reactive protein (CRP), thrombin generation, plasma clot permeability (Ks), clot lysis time (CLT), and fibrinolysis proteins. Results At baseline, NETosis did not differ depending on gender and cardiovascular risk factors but H3cit correlated with MPO (R=0.543, P<0.001) and CRP (R=0.540, P<0.001). All NETosis markers were inversely correlated with Ks. Median LDL-C reduction by 25% (P<0.001) on high-dose statin treatment was independent from H3cit reduction by 30.4%, MPO by 28.1%, and NE by 25.5% (in all P<0.001, Figure 1). The ΔH3cit and ΔMPO, but not ΔNE were associated with ΔCRP (R=0.855, P<0.001; R=0.250, P=0.004, respectively), Δthrombin activatable fibrinolysis inhibitor (TAFI) (R=0.385, P<0.001; R=0.245, P=0.005), and inversely with ΔKs (R=-0.315, P<0.001; R=-0.395, P=0.001). In multivariable analysis the H3cit decrease was independently associated with ΔCRP (β=0.771, P<0.001), ΔTAFI (β=0.125, P=0.013) and Δfibrinogen (β=0.106, P=0.034) but not with ΔLDL-C. Conclusions As has been shown for the first time high-dose statin treatment reduces levels of NETs-related markers, regardless of lipid-lowering effect in CAD patients.

High dose statin treatment reduces circulating Dickkopf-1 following acute myocardial infarction

BackgroundSecreted glycoproteins of the Dickkopf (DKK) family modify Wnt signaling and may influence plaque destabilization but their modulation by statins in MI patients is not known. MethodsWe measured plasma DKK-1 and DKK-3 in patients with acute ST-segment elevation MI (STEMI) before percutaneous coronary intervention (PCI) and after 2 and 7 days and 2 months in patients receiving short-term high-dose (40 mg rosuvastatin, given before PCI; n = 25) and moderate dose (20 mg simvastatin, given the day after PCI; n = 34). In vitro modulation of DKK-1 in human umbilical vein endothelial cells (HUVECs) by statins were assessed. Results(i) Patients receiving high dose rosuvastatin had a marked decline in DKK-1 at day 2 which was maintained throughout the study period. However, a more prevalent use of β-blockers in the simvastatin group, that could have contributed to higher DKK-1 levels in these patients. (ii) There was a strong correlation between baseline DKK-1 levels and change in DKK-1 from baseline to day 2 in patients receiving high dose rosuvastatin treatment. (iii) DKK-3 increased at day 2 but returned to baseline levels at 2 months in both treatment groups. (iv) Statin treatment dose-dependently decreased DKK-1 mRNA and protein levels in HUVEC. ConclusionsOur findings suggest that high dose statin treatment with 40 mg rosuvastatin could persistently down-regulate DKK-1 levels, even at 2 months after the initial event in STEMI patients.

Statin therapy after elective abdominal aortic aneurysm repair improves long-term survival.

Patients with abdominal aortic aneurysms are at high risk of cardiovascular events. Although statin therapy is indicated for most of these patients, no specific recommendation regarding the intensity of therapy exists. The aim of this study was to assess the possible effect of statin therapy on survival of patients undergoing abdominal aortic aneurysm repair and to investigate if high-intensity statin therapy was superior to low-moderate-intensity therapy. Data from nationwide Swedish registers on hospital admissions, operations, and medications for patients undergoing elective abdominal aortic aneurysm repair from 2006 to 2018 were collected. The effect of statin use was evaluated in three separate propensity score matched cohorts: perioperative mortality was analysed according to whether patients were on statins before abdominal aortic aneurysm repair or not; long-term survival was assessed according to whether patients were on statins during follow-up or not; and, for those on statins after surgery, long-term survival was analysed according to whether patients were on high-intensity or low-moderate-intensity statin therapy. Preoperative statin use did not reduce 90-day perioperative mortality (OR 0.99, 95% c.i. 0.77 to 1.28), whilst there was a marked benefit regarding long-term survival for postoperative statin users (HR 1.43, 95% c.i. 1.34 to 1.54). High-intensity statin therapy had no advantage over low-medium-intensity statin therapy with regards to long-term survival (HR 1.00, 95% c.i. 0.80 to 1.25). In this nationwide propensity score matched cohort study, preoperative statin treatment had no benefit regarding 90-day perioperative survival, but postoperative statin treatment markedly improved long-term survival. No additional benefit regarding high-dose statin treatment could be confirmed in this analysis.

Lipophilic Statins Eliminate Senescent Endothelial Cells by inducing Anoikis-Related Cell Death.

Pre-clinical studies from the recent past have indicated that senescent cells can negatively affect health and contribute to premature aging. Targeted eradication of these cells has been shown to improve the health of aged experimental animals, leading to a clinical interest in finding compounds that selectively eliminate senescent cells while sparing non-senescent ones. In our study, we identified a senolytic capacity of statins, which are lipid-lowering drugs prescribed to patients at high risk of cardiovascular events. Using two different models of senescence in human vascular endothelial cells (HUVECs), we found that statins preferentially eliminated senescent cells, while leaving non-senescent cells unharmed. We observed that the senolytic effect of statins could be negated with the co-administration of mevalonic acid and that statins induced cell detachment leading to anoikis-like apoptosis, as evidenced by real-time visualization of caspase-3/7 activation. Our findings suggest that statins possess a senolytic property, possibly also contributing to their described beneficial cardiovascular effects. Further studies are needed to explore the potential of short-term, high-dose statin treatment as a candidate senolytic therapy.

Reduction of perivascular inflammation following long-term statin treatment - a coronary CT follow-up study using Fat Attenuation Index

Abstract Background Perivascular fat attenuation index (FAI) assessed by coronary computed tomography (CCTA) has been demonstrated to represent a reliable marker of coronary inflammation. Several studies have explored the potential anti-inflammatory effects of statins in reducing the risk of plaque rupture and subsequent cardiovascular events. However, the effect of statin therapy on FAI has not been clearly demonstrated so far. Purpose Our objective was to investigate the changes in perivascular FAI at the level of coronary lesions, as measured by coronary computed tomography (CCTA), following long-term high-dose statin therapy. Methods This study includes 23 patients who presented with typical chest pain, had a low to intermediate likelihood of coronary artery disease, and underwent a CCTA examination which revealed the existence of at least one coronary atheromatous plaque. Statin therapy was initiated in all patients according to guidelines. The CCTA was repeated after a time interval ranging from 1.5 to 3 years. Lesion-specific perivascular FAI, together with different plaque characteristics, were measured at both baseline and follow-up using a new AI-powered medical device called CaRi-Heart®. Results The mean age of the participants was 61.72 ± 8.86 at the time of the first scan, and 65.21% (n = 15) of them were male. At baseline, the CT density of the adipose tissue (ranging from -190 to -30 HU), was not significantly different between the two groups. A significant decrease in serum lipids following statin therapy was recorded during follow-up: from 193.4 ± 47.09 to 145.2 ± 34.7, p = 0.04 for total cholesterol, and from 101.77 ± 25.20 to 86.41 ± 21.09, p = 0.02 for LDL cholesterol. The FAI-score consistently decreased from baseline to follow-up, especially in the left anterior descending artery: from 15.87 ± 9.32 vs. 12.40 ± 7.55, p = 0.04, while there was no significant decrease in coronary inflammation at the level of left circumflex artery (13.98 ± 6.16 vs. 13.10 ± 6.59, p = ns), or right coronary artery (20.53 ± 13.74 vs. 19.96 ± 16.24, p = ns). Similarly, the FAI-Score Centile values were lower during the second scan, specifically for LAD (0.51 ± 0.28 vs. 0.69 ± 0.29, p = 0.04), while there were no significant differences of FAI score centile in the LCX (0.72 ± 0.28 vs. 0.74 ± 0.26, p = ns) and RCA (0.71 ± 0.32 vs. 0.78 ± 0.21, p = ns). Conclusion CaRi-Heart® mapping technology revealed a significant decrease of coronary inflammation, as expressed by the FAI-score, as a result of high-dose statin treatment especially at the level of the LAD. This indicates a potential role of local factors related to coronary circulation in the complex process of plaque inflammation. The perivascular FAI-score and FAI-score centile may serve as promising imaging biomarkers for monitoring the anti-inflammatory response to statin treatments.Color-coded FAI MappingPVAT-FAI Score of Coronary Inflammation

Modern strategy of combined antihyperlipidemic therapy in the post-infarction period: focus on phytosteroid saponins

Patients who have suffered a myocardial infarction have a high risk of recurrent cardiovascular events – almost every fifth patient develops new episodes of acute myocardial ischemia during the first year [5]. One of the most important tasks of the therapy of these patients is the most effective and early reduction of atherogenic lipoprotein fractions to target values. The initiating basic therapy is statins, which have proven to be highly effective. However, in a number of patients, the necessary high-dose statin treatment cannot be implemented due to developing side effects or intolerance. The article discusses the issues of combined antihyperlipidemic therapy with a discussion of the role of all available groups of drugs. A possible clinical and pharmacological niche of phyto-steroid saponins is being considered.

Differential prediction of high-sensitivity cardiac troponin-I, but not N-terminal pro-brain natriuretic peptide, in different pitavastatin doses on cardiovascular events in stable coronary artery disease

BackgroundThis study aimed to examine whether high-sensitivity cardiac troponin-I (hsTnI) and N-terminal pro-brain natriuretic peptide (NT-proBNP) could predict future major adverse cardiovascular events (MACE) in stable coronary artery disease (CAD) patients with high- or low-dose of pitavastatin. MethodsThis was a case-cohort analysis of the REAL-CAD study, a randomized trial of high- or low-dose (4 or 1 mg/day) pitavastatin therapy in patients with stable CAD. We examined the MACE risk according to the quartile of hsTnI and NT-proBNP at baseline. ResultsA total of 1336 and 1396 patients including 582 MACE cases were randomly examined into the hsTnI and NT-proBNP cohort, respectively. Both higher levels of hsTnI and NT-proBNP at baseline were significantly associated with increased risk of MACE (p < 0.001, respectively). When separately analyzed in statin dose, the higher marker levels were significantly associated with higher MACE risk in all cohorts (p < 0.001 in all cohorts). After multivariable adjustment, hsTnI levels were significantly associated with MACE risk in low-dose statin group (HR 2.54, p = 0.0001); however, in high-dose pitavastatin therapy, a significant association was diminished in MACE risk among the quartiles of baseline hsTnI levels (p = 0.154). Conversely in the NT-proBNP cohort, the association between NT-proBNP levels and MACE risk was constantly observed regardless of pitavastatin dose even after multivariable adjustment (both p < 0.0001). ConclusionsPatients with high hsTnI levels had high risk of MACE in low-dose statin group, but not in high-dose, suggesting that high-dose statin treatment might decrease MACE risk in stable CAD patients with high hsTnI levels.

Effect of high-dose statin therapy on coagulation factors: Lowering of factor XI as a modifier of fibrin clot properties in coronary artery disease

BackgroundMultiple pleiotropic effects of statins include antithrombotic properties with formation of looser fibrin networks more susceptible to lysis. Recently, rosuvastatin 20 mg/d has been reported to decrease coagulation factors (F) VII, FVIII and FXI in venous thrombosis patients. ObjectivesWe investigated how high-dose statin therapy recommended in coronary artery disease (CAD) alters plasma levels of coagulation factors and if such changes might affect fibrin clot properties. MethodsWe studied 130 advanced CAD patients, who initially did not achieve the target low-density lipoprotein cholesterol (LDL-C). Before high-dose statin therapy (rosuvastatin 40 mg/d or atorvastatin 80 mg/d) and 6–12 months after its initiation, FII, FV, FVII, FVIII, FIX, FX, FXI and fibrinogen were assessed. We evaluated the impact of statin-induced alterations to the factors on plasma fibrin clot permeability (Ks) reflecting a fibrin pore size, and clot lysis time (CLT) reflecting fibrinolytic potential. ResultsAt baseline LDL-C (median 3.2, interquartile range 2.7–3.7 mmol/L) was independently associated solely with FXI (β = 0.58, P < 0.001). Median LDL-C reduction by 25% (P < 0.001) on high-dose statin treatment was accompanied by lowering of FVII, FVIII, and FXI (for all P < 0.001). On high-dose statin treatment, Ks (R = 0.65, P < 0.001) inversely associated with CRP (β = −0.41, P < 0.001), LDL-C (β = −0.26, P = 0.001), and FXI (β = −0.18, P = 0.016). In turn, CLT (R = 0.45, P < 0.001) was positively associated with LDL-C (β = 0.19, P = 0.043) and FXI (β = 0.17, P = 0.049). ConclusionsHigh-dose statin therapy in CAD patients decreases FVII, FVIII, and FXI. The statin-induced reduction in FXI may contribute to less prothrombotic fibrin clot phenotype, indicating additional antithrombotic effect of high-dose statins.

Simvastatin therapy in higher dosages deteriorates bone quality: Consistent evidence from population-wide patient data and interventional mouse studies

BackgroundCombining mouse experiments with big data analysis of the Austrian population, we investigated the association between high-dose statin treatment and bone quality. MethodsThe bone microarchitecture of the femur and vertebral body L4 was measured in male and ovariectomized female mice on a high-fat diet containing simvastatin (1.2 g/kg). A sex-specific matched big data analysis of Austrian health insurance claims using multiple logistic regression models was conducted (simvastatin 60–80 mg/day vs. controls; males: n = 138,666; females: n = 155,055). ResultsHigh-dose simvastatin impaired bone quality in male and ovariectomized mice. In the trabecular femur, simvastatin reduced bone volume (µm3: ♂, 213 ± 15 vs. 131 ± 7, p < 0.0001; ♀, 66 ± 7 vs. 44 ± 5, p = 0.02) and trabecular number (1/mm: ♂, 1.88 ± 0.09 vs. 1.27 ± 0.06, p < 0.0001; ♀, 0.60 ± 0.05 vs. 0.43 ± 0.04, p = 0.01). In the cortical femur, bone volume (mm3: ♂, 1.44 ± 0.03 vs. 1.34 ± 0.03, p = 0.009; ♀, 1.33 ± 0.03 vs. 1.12 ± 0.03, p = 0.0002) and cortical thickness were impaired (µm: ♂, 211 ± 4 vs. 189 ± 4, p = 0.0004; ♀, 193 ± 3 vs. 169 ± 3, p < 0.0001). Similar impairments were found in vertebral body L4. Simvastatin-induced changes in weight or glucose metabolism were excluded as mediators of deteriorations in bone quality. Results from mice were supported by a matched cohort analysis showing an association between high-dose simvastatin and increased risk of osteoporosis in patients (♂, OR: 5.91, CI: 3.17–10.99, p < 0.001; ♀, OR: 4.16, CI: 2.92–5.92, p < 0.001). ConclusionHigh-dose simvastatin dramatically reduces bone quality in obese male and ovariectomized female mice, suggesting that direct drug action accounts for the association between high dosage and increased risk of osteoporosis as observed in comparable human cohorts. The underlying pathophysiological mechanisms behind this relationship are presently unknown and require further investigation.

Optimal target of LDL cholesterol level for statin treatment: challenges to monotonic relationship with cardiovascular events

BackgroundAggressive lipid lowering by high-dose statin treatment has been established for the secondary prevention of coronary artery disease (CAD). Regarding the low-density lipoprotein cholesterol (LDL-C) level, however, the “The lower is the better” concept has been controversial to date. We hypothesized that there is an optimal LDL-C level, i.e., a “threshold” value, below which the incidence of cardiovascular events is no longer reduced. We undertook a subanalysis of the REAL-CAD study to explore whether such an optimal target LDL-C level exists by a novel analysis procedure to verify the existence of a monotonic relationship.MethodsFor a total of 11,105 patients with CAD enrolled in the REAL-CAD study, the LDL-C level at 6 months after randomization and 5-year cardiovascular outcomes were assessed. We set the “threshold” value of the LDL-C level under which the hazards were assumed to be constant, by including an artificial covariate max (0, LDL-C − threshold) in the Cox model. The analysis was repeated with different LDL-C thresholds (every 10 mg/dl from 40 to 100 mg/dl) and the model fit was assessed by log-likelihood.ResultsFor primary outcomes such as the composite of cardiovascular death, non-fatal myocardial infarction, non-fatal ischemic stroke, and unstable angina requiring emergency hospitalization, the model fit assessed by log-likelihood was best when a threshold LDL-C value of 70 mg/dl was assumed. And in the model with a threshold LDL-C ≥ 70 mg/dl, the hazard ratio was 1.07 (95% confidence interval 1.01–1.13) as the LDL-C increased by 10 mg/dl. Therefore, the risk of cardiovascular events decreased monotonically until the LDL-C level was lowered to 70 mg/dl, but when the level was further reduced, the risk was independent of LDL-C.ConclusionsOur analysis model suggests that a “threshold” value of LDL-C might exist for the secondary prevention of cardiovascular events in Japanese patients with CAD, and this threshold might be 70 mg/dl for primary composite outcomes.Trial registrationhttp://www.clinicaltrials.gov.

Intensive low-density lipoprotein cholesterol lowering improves fibrin clot properties: Association with lipoproteins and C-reactive protein

ObjectiveDense fibrin networks resistant to lysis characterize coronary artery disease (CAD) patients. We investigated whether a statin-induced decrease of low-density lipoprotein cholesterol (LDL-C) could improve fibrin clot phenotype in CAD patients. MethodsWe recruited 130 consecutive patients with advanced CAD (baseline LDL-C of 4.4 [IQR, 3.8–4.8] mmol/L), who on statins did not achieve the LDL-C goal based on the 2016 ESC/EAS guidelines. On standard statin treatment and after 6–12 months of high-dose statin treatment (atorvastatin 80 mg/day or rosuvastatin 40 mg/day), plasma fibrin clot permeability (Ks), clot lysis time (CLT), thrombin generation, coagulation and fibrinolytic factors were determined. ResultsAfter a median high-dose statin therapy of 7 months there was 25% reduction in LDL-C associated with increased Ks and shorter CLT, together with lower thrombin activatable fibrinolysis inhibitor, factor VIII, D-dimer, and C-reactive protein (CRP); thrombin generation was unaltered. The patients who achieved the therapeutic goal (n = 49, 37.7%) had 29.2% increase in Ks and 16.3% shorter CLT compared with the standard therapy, while there were no similar changes in the remaining patients. After adjustment for potential confounders, including CRP, an increase in Ks (by 1 × 10−9 cm2) and decrease in CLT (by 10 min) were independently predicted by on-treatment LDL-C goal (odds ratio [OR] 6.23, 95% confidence interval [CI] 1.97–20.33 and OR 3.11, 95% CI 1.05–8.99, respectively). ConclusionsFor the first time we showed that a decrease of LDL-C ≤ 1.8 mmol/L, or a reduction of at least 50% if the baseline LDL-C is between 1.8 and 3.5 mmol/L, is associated with favorable alterations to fibrin clot phenotype, with a stronger impact of lipoprotein reduction than CRP lowering, which might suggest that other potent cholesterol-lowering drugs can exert similar antithrombotic actions.

Efficacy of high- versus moderate-dose statin therapy on lower extremity artery disease after revascularization

Aim: Statins are one of the most important agents in the treatment of atherosclerotic peripheral arterial disease. We aim to compare high- and moderate-dose statin therapy in patients with lower extremity artery disease (LEAD) who have undergone percutaneous transluminal angioplasty (PTA). Patients and Methods: Ninety-four patients treated with PTA were selected consecutively and retrospectively and were divided into two groups according to the high- or moderate-dose statin treatments they were given. Groups were compared for the absence of restenosis and occlusion as primary patency and the need for reintervention in the treated arterial segment as secondary patency. All patients underwent computed tomography (CT) angiography or duplex scan one year after receiving PTA. Results: Coronary revascularization (p&amp;lt;0.001) and prior statin usage (p:0.02) were more common in the high-dose statin group when compared to the moderate-dose statin group. Lesion characteristics did not differ between the two groups. Primary patency rate was significantly higher (36.1% vs. 27.6%, p 0.01) in the high-dose statin group. Major amputation (4.2% vs. 10.6%, p:0.03) and minor amputation (12.7% vs. 19.1%, p:0.03) rates were significantly lower in the high-dose statin group. Regression analysis revealed that the usage of high-dose statin therapy was an independent predictor of higher primary patency in patients who were treated with prior PTA(Odds ratio:2.208, p&amp;lt;0.001) Conclusion: High-dose long-term statin treatment might have better outcomes on primary patency in patients who underwent prior PTA for infrapopliteal lesions as a subgroup of peripheral artery disease. The administration of the high-dose long-term statin therapy might be important in the prognosis of peripheral arterial disease, especially for those with infrapopliteal lesions.

Analysis of the impact on the health care budget and consumers of the use of the preparation of omega-3 acid ethyl esters90 in the treatment of patients with atherogenic dyslipidemia.

Aim To evaluate economic results of using omega-3 acid ethyl esters 90 for primary prevention of cardiovascular catastrophes in patients with residual hypertriglyceridemia (HTG).Material and methods The economic evaluation of using the medicine omega-3 acid ethyl esters 90 in the system of drug provision of the population of the Russian Federation was performed by analyzing the effect on the budget using a pharmacoeconomic model developed with the Microsoft Office Excel 2016 software. The effect of omega-3 acid ethyl esters 90 was evaluated in 555 643 patients with residual HGT (Moscow). The study lasted for one year. Results of the meta-analysis by A.A. Bernasconi et al. (2020) were used as a source of efficacy data. The following direct and indirect medical expenses for treatment of cardiovascular complications of residual HTG were taken into account in this study: expenses for drug therapy; expenses for therapy and rehabilitation for nonfatal complications; expenses for fatal outcomes; state support for disability; foregone per capita gross domestic product resulting from losses of earnings due to temporary incapacity to labor by people of work-able age; and salary payments for temporary incapacity to work.Results Using omega-3 acid ethyl esters 90 in 555 643 patients with residual HTG will allow preventing 1 437 fatal ischemic cardiovascular complications (including 564 deaths from ischemic heart disease and 1 128 cases of myocardial infarction (MI), including 558 fatal cases of MI). Furthermore, the difference in expenses compared to the high-dose statin treatment alone will be 359 252 253 rubles or 0.32 %.Conclusion The results of this comprehensive pharmacoeconomical study showed that the use of omega-3 acid ethyl esters 90 in patients with residual HGT is an economically preferrable strategy compared to high-dose statin treatment alone and does not influence significantly the budgetary expenses as a part of the State Guarantee of Free Medical Care to the Citizens of the Russian Federation (increase in expenses by 0.32 % compared to the current practice). At the same time, the use of omega-3 acid ethyl esters 90 results in a 10% decrease in the number of fatal ischemic cardiovascular complications.

How to Use Statins in Secondary Prevention of Atherosclerotic Diseases: from the Beneficial Early Initiation to the Potentially Unfavorable Discontinuation.

Statins, a class of lipid-lowering drugs, reduce morbidity and mortality in patients with established atherosclerosis-related cardiovascular disease. Early initiation of statin therapy after admission for acute coronary syndromes (ACS), stroke, or transient ischemic attack (TIA) is associated with improved cardiovascular outcomes. Moreover, high-dose statin treatment prior to coronary or carotid revascularization has been shown to reduce cardiovascular events in these patients. However, many patients may be undertreated, and a residual cardiovascular risk remains in current clinical practice. Despite the beneficial role of statins, their discontinuation rate among patients is still elevated leading to severe adverse cardiovascular events due to atherosclerotic plaque destabilization. In this review, we summarized the impact of statin treatment among patients, focusing on the initiation time-points as well as the potential harm derived by their discontinuation.

Major Depressive Disorder (MDD) and Antidepressant Medication Are Overrepresented in High-Dose Statin Treatment.

Objective: To examine the dose-dependent relationship of different types of statins with the occurrence of major depressive disorder (MDD) and prescription of antidepressant medication.Methods: This cross-sectional study used medical claims data for the general Austrian population (n = 7,481,168) to identify all statin-treated patients. We analyzed all patients with MDD undergoing statin treatment and calculated the average defined daily dose for six different types of statins. In a sub-analysis conducted independently of inpatient care, we investigated all patients on antidepressant medication (statin-treated patients: n = 98,913; non-statin-treated patients: n = 789,683). Multivariate logistic regression analyses were conducted to calculate the risk of diagnosed MDD and prescription of antidepressant medication in patients treated with different types of statins and dosages compared to non-statin-treated patients.Results: In this study, there was an overrepresentation of MDD in statin-treated patients when compared to non-statin-treated patients (OR: 1.22, 95% CI: 1.20–1.25). However, there was a dose dependent relationship between statins and diagnosis of MDD. Compared to controls, the ORs of MDD were lower for low-dose statin-treated patients (simvastatin>0– < =10 mg:OR: 0.59, 95% CI: 0.54–0.64; atorvastatin>0– < =10 mg:OR:0.65, 95%CI: 0.59–0.70; rosuvastatin>0– < =10 mg:OR: 0.68, 95% CI: 0.53–0.85). In higher statin dosages there was an overrepresentation of MDD (simvastatin>40– < =60 mg:OR: 2.42, 95% CI: 2.18–2.70, >60–80 mg:OR: 5.27, 95% CI: 4.21–6.60; atorvastatin>40– < =60 mg:OR: 2.71, 95% CI: 1.98–3.72, >60– < =80 mg:OR: 3.73, 95% CI: 2.22–6.28; rosuvastatin>20– < =40 mg:OR: 2.09, 95% CI: 1.31–3.34). The results were confirmed in a sex-specific analysis and in a cohort of patients taking antidepressants, prescribed independently of inpatient care.Conclusions: This study shows that it is important to carefully re-investigate the relationship between statins and MDD. High-dose statin treatment was related to an overrepresentation, low-dose statin treatment to an underrepresentation of MDD.

Preclinical investigation of neoatherosclerosis in magnesium-based bioresorbable scaffolds versus thick-strut drug-eluting stents

Neoatherosclerosis is a frequent finding after implantation of permanent metallic stents. Bioresorbable scaffolds (BRS) are considered to reduce the incidence of neoatherosclerosis owing to their dissolution and consequent vascular restoration. The aim of this study was to evaluate the formation of neoatherosclerosis between magnesium-based BRS and thick-strut metallic drug-eluting stents (DES) in a rabbit model of neoatherosclerosis and in proportion to the effect of high-dose statin medication. Fully bioresorbable magnesium scaffolds (BRS, n=45) and thick-strut permanent metallic DES of equivalent geometry and design (n=45) were implanted into the iliac arteries of New Zealand White rabbits (n=45) following endothelial balloon injury and exposure to a cholesterol diet. Endothelialisation was assessed in 12 animals after 35 days using scanning electron microscopy (SEM), showing significantly enhanced re-endothelialisation above struts in the BRS (n=13) compared to DES (n=10). Eleven (11) animals were terminated for baseline assessment after 91 days while the remaining 22 animals were randomised to receive high-dose statin treatment (3 mg/kg) or placebo. BRS-treated vessels showed a significant reduction in foam cell infiltration as a sign of early neoatherosclerosis by histology and OCT when compared to thick-strut DES-treated vessels. Statin treatment resulted in significant reduction of foam cell infiltration in BRS and DES by histology. Our findings suggest reduced neoatherosclerosis formation in magnesium-based BRS relative to thick-strut DES. High-dose statin treatment may be a promising measure to reduce neoatherosclerosis progression, both on its own and in synergy with site-targeted device-based treatment.
