Abstract
BACKGROUND The aim of this study is to compare the long-term prognosis of non-ST elevation acute coronary syndrome (NSTE-ACS) patients with 3-vessel disease (3VD) who underwent percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG) or medical therapy (MT).Methods and Results:Overall, 3,928 NSTE-ACS patients with 3VD were consecutively enrolled from April 2004 to February 2011 at Fu Wai Hospital. Patients were followed up for a median of 7.5 years, and were divided into PCI, CABG or MT groups according to their treatment. Compared with patients undergoing PCI, CABG patients had lower rates of myocardial infarction (MI), unplanned revascularization, major adverse cardiovascular and cerebrovascular events (MACCE) and a higher rate of stroke (all P<0.05). Compared with MT, PCI and CABG had lower incidences of all adverse outcomes (all P<0.05), except for a similar rate of stroke between PCI and MT. Kaplan-Meier analysis showed similar results. After adjusting for confounders, CABG was independently associated with a lower risk of cardiac death, revascularization and MACCE compared with PCI (all P<0.05). Compared with MT, PCI reduced long-term risk of death, whereas CABG reduced long-term risk of death, revascularization and MACCE events (all P<0.05). CONCLUSIONS In NSTE-ACS patients with 3VD, CABG is independently associated with a lower risk of long-term cardiac death, revascularization and MACCE compared with PCI. Patients who received MT alone had the highest risk of long-term MACCE.

The Role of Statins in Current Guidelines.
Rached, F, Santos, RD
Current atherosclerosis reports. 2020;(9):50
Abstract
PURPOSE OF REVIEW The causal association of LDL-cholesterol (LDL-C) with atherosclerotic cardiovascular disease (ASCVD) has been demonstrated in robust experimental, epidemiological, genetic, and interventional randomized controlled trials (RCTs). The goal of this review is to show how the knowledge acquired from statin RCTs influenced and was recommended on guidelines for prevention of ASCVD during the last three decades. RECENT FINDINGS Guideline recommendations have evolved with accruing information derived mostly from statin RCTs, and as decades passed, more intensive LDL-C lowering was recommended according to a given ASCVD risk. Recent guidelines are unanimous in recommending intensive LDL-C lowering for the highest-risk individuals; however, they differ regarding risk stratification tools, use of specific LDL-C targets, management of primary prevention individuals, and thresholds to start non-statin lipid-lowering therapies. Even considering the advent of non-statin therapies like ezetimibe and PCSK9 inhibitors, due to their efficacy, safety, and low cost, guidelines state that statins persist as the main component of ASCVD preventive strategies and should be prescribed in adequate doses to attain evidence-based LDL-C lowering.

Clinical Pharmacology of Statins: an Update.
Ferri, N, Corsini, A
Current atherosclerosis reports. 2020;(7):26
Abstract
PURPOSE OF REVIEW Statins represent the cornerstone for the treatment of hypercholesterolemia, although muscle-related side effects and dysregulation of glucose metabolism have strongly limited their adherence and compliance especially in primary prevention therapy. The purpose of the present review is to provide the most recent evidence of the efficacy and safety of statins in monotherapy or combination with new lipid-lowering drugs. RECENT FINDINGS Recent "life-long" analysis conducted on young familial hypercholesterolemia patients, elderly hypocholesterolemic subjects, and from a 20-year follow-up of randomized controlled trial (RCT) have been published confirming that the cardiovascular benefits of statin therapy, in patients for whom it is recommended by current guidelines, greatly outweigh the risks of side effects. In addition, recent therapies to be used in combination with statins have shown to increase the percentage of patients at goal for low-density lipoprotein - cholesterol (LDL-C) with a good safety profile. The cardiovascular (CV) benefits of monoclonal antibodies anti-proprotein convertase subtilisin/kexin type 9 (PCSK9) and ezetimibe, in patients under statin therapy, have been proven by specific RCT, while we are still waiting for the results of bempedoic acid and the small-interfering RNA (si-RNA) anti-PCSK9 inclisiran. Taken together, the approval of new pharmacological agents to be used in combination with statins represents the future for a tailored therapy of cardiovascular disease patients.

The Rationale, Indications, Safety, and Use of Statins in the Pediatric Population.
Khoury, M, McCrindle, BW
The Canadian journal of cardiology. 2020;(9):1372-1383
Abstract
Together with heart-healthy lifestyle habits, statins serve as the cornerstone of primary and secondary prevention of atherosclerotic cardiovascular disease in adults. Several conditions, most notably familial hypercholesterolemia (FH), cause early dyslipidemia and vascular disease, contributing to the development and progression of atherosclerosis from childhood and increased cardiovascular risk. In recent decades, studies increasingly have evaluated the safety and efficacy of statins in such high-risk youth. The strongest evidence for pediatric statin use is for the heterozygous FH population, whereby statin use has been shown to lower low-density lipoprotein cholesterol effectively, slow the progression of atherosclerosis and vascular dysfunction, and significantly reduce cardiovascular risk in early adulthood. Numerous meta-analyses and Cochrane reviews have demonstrated that attributed adverse effects, including liver toxicity, myositis, and rhabdomyolysis, occur no more frequently in youth receiving statins than placebos, with no impact on growth or development. However, further studies evaluating the long-term safety of pediatric statin use are required. In the current review, we summarize the pediatric experience of statin use to date, focusing on its utility for FH, Kawasaki disease, post-heart transplantation, and other at-risk populations. Current guidelines and indications for use are summarized, and the short- and medium-term safety experience is reviewed. Finally, a clinical approach to the indications, initiation, and monitoring of statins in youth is provided.

Patient characteristics, treatment patterns, and adherence to lipid-lowering therapies following an acute coronary syndrome.
Bruckert, E, Desamericq, G, Khachatryan, A, Ngo, P, Gusto, G, Sorio-Vilela, F
Reviews in cardiovascular medicine. 2020;(4):643-650
Abstract
Despite dyslipidaemia management guidelines, many patients do not reach low-density lipoprotein cholesterol targets due to insufficiently intensive regimens or lack of adherence to their medication. This was a retrospective cohort study on the Pharmacoepidemiologic General Research eXtension (PGRx)-acute coronary syndrome (ACS) registry. Patients included were ≥ 18 years old who suffered an ACS between 2013 and 2016, and treated with lipid-lowering therapy (LLT) at hospital discharge or within 92 days. Patients were followed up to 12 months' post index ACS, a new cardiovascular event, loss to follow-up or death. Treatment intensity (high, moderate and low intensity statins ± ezetimibe) and adherence (proportion of days covered > 80%) are described. A total of 2,695 patients were included; mean age [SD] was 63.1 [12.8] years, and 77% were men. High, moderate and low intensity statins were started in 56% (1,520), 36% (971), and 3% (86) of patients, respectively. A further 2% (46) were on statin/ezetimibe combination, 2% (42) on other LLT and 1% (30) on ezetimibe alone. At follow-up, around 70% of patients were adherent to LLT, with those on moderate intensity treatments showing better adherence (76%) than those on low (63%) or high (67%) intensity treatments. Despite guideline recommendations, many patients following an ACS are not treated with high intensity statins, and adherence remains far from optimal. Effort should be made to increase the proportion of patients treated with high intensity statins following an ACS and to further improve treatment adherence.

Abstract
BACKGROUND The statistical association between a short-term rise in low-density lipoprotein cholesterol (LDL-C) levels and the short-term outcome of acute ischemic stroke remains unknown. We aimed to evaluate the association in acute ischemic stroke patients during hospitalization. METHODS Patients with acute ischemic stroke who received statin at discharge were enrolled in this multicenter registry study. LDL-C values were measured on the first day after admission and on the day before discharge to determine the rise in LDL-C levels. Poor outcome was defined as a modified Ranking Scale score ≥2 at discharge. The National Institutes of Health Stroke Scale increase from admission to discharge by 2 points was defined as clinical deterioration. Logistic regression analyses were used to analyze the relationship between LDL-C rise during hospitalization and poor outcome at discharge. Variables that were significantly different between the LDL-C rise and LDL-C fall groups were considered in adjustment for confounding variables in model 1. Age, sex, and those variables in model 1 were considered in adjustment for confounding variables in model 2. RESULTS Among the 676 patients, 110 (16.3%) showed a rise in LDL-C levels during hospitalization. Multivariate analyses showed that LDL-C at admission <1.6 mmol/L was significantly correlated with LDL-C rise during hospitalization (p < 0.001). There were significantly more patients with a poor outcome in the "LDL-C rise" group than in the "LDL-fall" group (p = 0.002). Multiple models consistently showed that LDL-C rise increased the risk of a poor outcome at discharge in model 1 (OR [95% CI] 1.351 [1.059-1.723], p = 0.016) and model 2 (OR [95% CI] 1.370 [1.071-1.751], p = 0.012). LDL-C rise also increased the risk of clinical deterioration, although its p value only was 0.043 in model 1 and 0.048 in model 2. CONCLUSIONS Rise in LDL-C during hospitalization from acute ischemic stroke is an independent predictor of poor outcome at discharge. In particular, patients with lower LDL-C values at admission are a higher at risk, and LDL-C in these patients should thus be monitored while in hospital.

Abstract
BACKGROUND Patients with type 2 diabetes mellitus characteristically display an atherogenic lipid profile with high triglyceride concentrations, low high-density lipoprotein cholesterol (HDL-C) concentrations and low-density lipoprotein cholesterol (LDL-C) concentrations not always elevated. It is unclear if patients with diabetes who present with an acute coronary syndrome (ACS) receive different or more-potent lipid-lowering therapy (LLT). AIMS To investigate lipid abnormalities in patients with and without type 2 diabetes hospitalised for an ACS, and use of LLT before admission and 4 months after the event. METHODS Patients were included in the observational DYSIS II study if they were hospitalised for an ACS and had a full lipid profile. RESULTS Of 3803 patients, diabetes was documented in 1344 (54.7%). Compared to patients without diabetes, those with diabetes had a lower mean LDL-C (101.2 vs. 112.0mg/dL; 2.6 vs. 2.9mmol/L; P<0.0001), with a greater proportion attaining concentrations<70mg/dL (1.8mmol/L) (23.9% vs. 16.0%; P<0.0001) and<55mg/dL (1.4mmol/L) (11.3% vs. 7.3%; P<0.0001), a higher mean triglyceride concentration (139.0 vs. 121.0mg/dL; 1.6 vs. 1.4mmol/L; P<0.0001) and a lower HDL-C concentration. LLT was more commonly given to patients with diabetes (77.5% vs. 58.8%; P<0.0001); there were no differences in types of therapy prescribed. Four months after hospitalisation, most patients from both groups were being treated with LLT (predominantly statin monotherapy). CONCLUSIONS Despite the different lipid profiles, the type of LLT prescribed did not vary depending on the presence or absence of type 2 diabetes. There was no difference in LLT in patients with and without diabetes at 4-month follow-up, except for fibrates, which were used in 2% of patients with and 1% of patients without diabetes. Statin monotherapy of intermediate potency was the predominant treatment in both groups.

Abstract
PURPOSE OF REVIEW We aimed to summarize recent guidelines, position papers, and high-quality clinical research relating the use of nutraceuticals in the management of individuals at high risk of atherosclerotic cardiovascular disease. RECENT FINDINGS It is essential that individuals at high risk of cardiovascular disease receive guideline-directed evidence-based therapies to reduce their risk of morbidity and mortality from cardiovascular events. Compared with conventional therapeutics, nutraceuticals have undergone relatively little investigation in randomized controlled trials. Thus, recommendations for nutraceuticals in international guidelines are rare, and nutraceuticals should not be used preferentially in place of statins. Nevertheless, recent position papers from the International Lipid Expert Panel and clinical evidence from studies of triglyceride reduction by polyunsaturated fatty acid administration demonstrate that nutraceuticals do have an important role in optimizing therapy in individuals at high risk of cardiovascular disease. Roles for nutraceuticals include as follows: (1) managing residual risk associated with lipids other than low-density lipoprotein cholesterol (LDL-C); (2) managing non-lipid-mediated residual risk; (3) optimizing LDL-C treatment in statin intolerance; (4) optimizing LCL-C treatment when add-on therapies for statins are not available; (5) as adjuncts to lifestyle for individuals at high lifetime risk of atherosclerotic cardiovascular disease (ASCVD). The strength of evidence for each of these applications is variable. In addition to guideline-directed therapeutics, nutraceuticals may have roles in optimizing preventative therapy and targeting residual risk in individuals at high risk of ASCVD. Application of Good Manufacturing Practice and randomized controlled trials when producing and evaluating nutraceuticals will expand the armoury of evidence-based agents for the prevention of ASCVD.

Drug development research. 2020;(5):551-556
Abstract
OBJECTIVE To conduct a randomized double-blind prospective study to investigate effect of different doses of atorvastatin, rosuvastatin, and simvastatin on elderly patients with ST-elevation AMI after PCI. METHODS One hundred and ninety-two AMI patients over 60 years old who underwent PCI were randomly divided into six groups: the low atorvastatin group, high atorvastatin group; low rosuvastatin group; high rosuvastatin group; low simvastatin group; high simvastatin group. Demographic data and clinical information as well as coronary angiography parameters were recorded. Plasma levels of CK-MB, BNP, ALT, and TnI were measured at 12 hr, 24 hr, and 1 week after PCI. Major cardiovascular events (MACE) were recorded and analyzed using Kaplan-Meier (K-M) curve. RESULTS No significant differences were observed in angiographic and procedural characteristics. In all high dose groups, all levels of CK-MB, BNP, ALT, and TnI were significantly lower. However, after 1 week of PCI, only CK-MB, BNP, and TnI showed significant difference between high and low dose groups. Patients in high dose groups had significantly lower rates for surgical or percutaneous intervention, recurrence of angina, and rehospitalization. K-M curve analysis also showed cumulative incidence freedom time of overall MACE in high dose groups was significantly longer. No significant differences were found among different drugs with the same doses. CONCLUSION Patients with higher doses had lower level of CK-MB, BNP, ALT, and TnI and lower occurrence of MACE after PCI.

Abstract
Statin therapy response is highly variable. Variants of lipid metabolism genes and statin pharmacokinetic modulators could play a role, however, the impact of most of these variants remains unconfirmed. A prospective and multicenter study included 252 patients was carried out in order to assess, according to achievement of LDL-C or non-HDL-C therapeutic targets and quantitative changes in lipid profiles, the impact of CETP, ABCA1, CYP2D6, and CYP2C9 gene candidate variants on the simvastatin, atorvastatin, and rosuvastatin response. Patients carrier ABCA1 rs2230806 and CYP2D6*3 variants are less likely to achieve therapeutic lipid targets (p = 0.020, OR = 0.59 [0.37, 0.93]; p = 0.040, OR = 0.23 [0.05, 0.93], respectively). Among CETP variants, rs708272 was linked to a 10.56% smaller reduction in LDL-C with rosuvastatin (95% CI = [1.27, 19.86] %; p = 0.028). In contrast, carriers of rs5882 had a 13.33% greater reduction in LDL-C (95% CI = [25.38, 1.28]; p = 0.032). If these findings are confirmed, ABCA1, CYP2D6, and CETP genotyping could be used to help predict which statin and dosage is appropriate in order to improve personalized medicine.
