Cardiovascular Morbidity And Mortality

Statin therapy is proven to reduce cardiovascular morbidity and mortality in people with diabetes, and high-dose statins are recommended for people with established atherosclerotic vascular disease. In two dedicated studies in people with diabetes, fibrates did not significantly reduce cardiovascular events and were associated with serious side effects. A similar lack of benefit was seen in two large studies of niacin. Ezetimibe, when added to statins, may further reduce LDL cholesterol and non-fatal vascular events. The PCSK9 inhibitors are a new class of subcutaneous lipid- lowering drugs which cause profound reductions in LDL cholesterol when added to statins. Evolocumab reduced non-fatal cardiovascular events when added to background statin therapy in a larger group of subjects and the benefits were confirmed in a diabetes subgroup. In another large trial alirocumab reduced major adverse cardiovascular events and total mortality. The clinical use of ezetimibe and PCSK9 inhibitors is currently limited by cost.

Meta Analyses

Arterial stiffness (AS) is considered an independent predictor of cardiovascular disease (CVD) events. Among lipid lowering drugs, statins have a beneficial effect on AS, independent of their hypolipidaemic effect. Based on 3 meta-analyses and other studies, this effect is compound- and doserelated. Potent statins at high doses are more effective than less powerful statins. Ezetimibe (± statin) also seems to decrease AS in patients with dyslipidaemia. Fibrates have no effect on AS. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors have data that beneficially affect all AS risk factors, suggesting a beneficial effect on artery compliance. However, there is no direct measurement of their effect on AS indices. In patients with dyslipidaemia, prescribing high dose statins (± ezetimibe) will not only decrease low-density lipoprotein cholesterol levels but also improve AS (in addition to other effects). This effect on AS may contribute to the observed reduction in vascular events.

Lowering Therapy

Abstract Background Lipid lowering therapy is a key cornerstone in secondary prevention of patients with coronary artery disease. However, only a minority of patients with statin therapy reach LDL thresholds as suggested by the ESC. Ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK-9) inhibitors allow for reduction in LDL-cholesterol in addition to statin therapy. Purpose To perform a meta-analysis of existing trials, evaluating how lipid lowering therapy beyond statins impacts cardiovascular outcome. Methods We performed a systematic search using the Pubmed, Cochrane, SCOPUS, and Web of Science databases for studies, evaluating the impact of an intensified lipid lowering therapy via ezetimibe or PCSK-9 inhibitor in addition to statin therapy compared to statin therapy alone. Manuscript and congress presentations, published until 1st of November 2018, were included. We made our search specific and sensitive using Medical Subject Headings terms and free text and considered studies published in English language. Search terms used were “ezetimibe”, “evolocumab”, “alirocumab”, or “bococizumab” and “cardiovascular events”. Results A total of 100,610 patients from 9 randomized controlled trials (IMPROVE-IT, FOURIER, ODYSSEY Outcomes, SIPRE I, SPIRE II, ODYSSEY LONG TERM, OSLER-1 and OSLER-2, HIJ-PROPER) were included. Treatment with ezetimibe or a PCSK-9 inhibitor was associated with a 18% risk reduction in cardiovascular events (OR [95% CI]: 0.82 [0.75–0.89]). Effect sizes were similar for myocardial infarction (0.84 [0.76–0.92]) and even more pronounced for ischemic stroke (0.77 [0.67–0.83]). In contrast, all-cause mortality was not improved by the intensified lipid lowering therapy (0.94 [0.85–1.05]). No relevant heterogeneity and inconsistency between groups was present in all analyses (detailed data not shown). Comparing efficacy of LDL-reduction and relative risk redaction of cardiovascular events, a linear relationship was observed (figure). Figure 1. Correlation of reduction of LDL-cholesterol at one year with relative risk reduction (95% confidence interval) of cardiovascular events in included trials. Conclusion Intensified LDL-lowering therapy with ezetimibe or PCSK-9 inhibitors, in addition to statins, reduces the risk of myocardial infarction and stroke, however, does not impact overall mortality. There is a linear relationship between LDL reduction and cardiovascular risk reduction, confirming the beneficial effects of LDL lowering therapy beyond statins in secondary prevention.

Treatment with statins is one of the most effective ways of reducing cardiovascular events in those with diabetes. Many studies containing thousands of subjects with diabetes have demonstrated that statins reduce cardiovascular events when there is no known cardiovascular disease (primary prevention) and in those with confirmed atherosclerotic disease (secondary prevention). High-dose statins appear to be even more effective in established cardiovascular disease, but at the expense of increased drug side effects. In this paper we review the evidence for the benefits of statins in diabetes. In a second review we will examine the evidence for possible benefits of other lipid-lowering therapies when these are added to background statin therapy in diabetes.

Background: Lipid metabolism plays an important role in viral infections. Large cohort study suggested a protective potential of lipid-lowering drugs in COVID-19 outcomes, but the nature of observational study precludes it to draw a causal inference. Objectives: To assess the causal effect of lipid-lowering drugs (HMGCR inhibitors, PCSK9 inhibitors and NPC1L1 inhibitors) on COVID-19 outcomes using 2-sample Mendelian Randomization (MR) study. Methods: We used two kinds of genetic instruments to proxy the exposure of lipid-lowering drugs, including expression quantitative trait loci (eQTLs) of drugs target genes, and genetic variants within or nearby drugs target genes associated with low-density lipoprotein (LDL) cholesterol from genome-wide association study (GWAS). GWASs of COVID-19 outcomes (susceptibility, hospitalization and very severe disease) were obtained from the COVID-19 Host Genetics Initiative. Summary-data-based MR (SMR) and inverse-variance weighted MR (IVW-MR) were used to calculate the effect estimates. Results: SMR analysis found that a higher expression of HMGCR was associated with a higher risk of COVID-19 hospitalization (OR=1.38, 95%CI=1.06-1.81; P=0.019). Similarly, IVW-MR analysis observed a positive association between HMGCR-mediated LDL cholesterol and COVID-19 hospitalization (OR=1.32, 95%CI=1.00-1.74; P=0.049). No consistent evidence from both SMR and IVW-MR analyses was found for the association of HMGCR inhibitors with COVID-19 susceptibility or very severe disease, or for the association of PCSK9 inhibitors and NPC1L1 inhibitor with COVID-19 outcomes. Conclusions: In this 2-sample MR study, we found potential causal evidence that HMGCR inhibitors could reduce the risk of COVID-19 hospitalization. Further research is needed to explore the therapeutic role of statins for COVID-19.

Coronary Syndromes

OBJECTIVE: To review the clinical benefit of statins in the early management of acute coronary syndromes (ACSs) and their possible mechanisms of benefit. DATA SOURCES: A MEDLINE search (1966–September 2001) was conducted using the following terms: pravastatin, lovastatin, simvastatin, atorvastatin, cerivastatin, fluvastatin, statins, hydroxymethylglutaryl coenzyme A reductase inhibitor, acute coronary syndromes, unstable angina, and myocardial infarction. Pertinent articles referenced in these publications were also reviewed. STUDY SELECTION AND DATA EXTRACTION: French- and English-language human and animal studies were selected and analyzed. DATA SYNTHESIS: In addition to their lipid-lowering properties, statins produce several nonlipid-related properties. These pleiotropic properties include improved endothelial function, reduction of inflammation at the site of the atherosclerotic plaque, inhibition of platelet aggregation, and anticoagulant effects, all of which may result in clinical benefit during ACSs. Preliminary studies and retrospective analyses of large clinical trials support the hypothesis that statins may be of benefit in ACSs. A recently published randomized, double-blind, multicenter trial evaluated the clinical impact of high-dose atorvastatin in patients with ACSs. Use of atorvastatin resulted in a decrease in a combined endpoint of cardiovascular events. Furthermore, initiation of statin therapy during hospitalization improves long-term compliance and may significantly improve clinical outcome. CONCLUSIONS: Early use of statins in ACSs appears to decrease cardiovascular events. We believe statin therapy should be initiated early (at the latest before hospital discharge) in all patients who have been hospitalized for ACSs. Ongoing studies will clarify the benefit of these agents in ACSs, the importance of their nonlipid-lowering properties, and the optimal cholesterol-target concentrations.

Background: Statins have been a major keystone in the management of patients with atherosclerotic cardiovascular disease. The benefits of inhibiting HMG CoA reductase, via statins, were translated into reduction in LDL-c with proportionate decrease in cardiovascular events in response to the magnitude of LDL-c reduction. Despite major advances in pharmacological treatments, including the use of high-dose statins, there are urgent need to further reduce future cardiovascular risk. This is in particularly important since 1 out of 5 high-risk atherosclerotic patients who achieve low LDL-c return with a second cardiovascular event within five years. Although this residual risk post-statin is largely heterogeneous, lowering LDL-c beyond ‘normal’ or guidelines-recommended level using novel therapies has resulted in further reduction in cardiovascular events. </P><P> Objective: The current review will discuss the use of PCSK9 inhibitors in patients with atherosclerotic disease. PCSK9 inhibitors are a new class of lipid-lowering drugs that are either fully human monoclonal antibodies (evolocumab and alirocumab) or humanised monoclonal antibodies (bococizumab) that effectively reduce LDL-c to unprecedented level. By blocking circulating PCSK9, these drugs would preserve LDL receptors and prevent them from cellular degradation. This process promotes recycling of LDL receptors back to hepatocytes surface, leading into further reduction of LDL-c. Combining PCSK9 inhibitors with statin have led into lower LDL-c, reduction in plaque volume and more importantly reduction in future cardiovascular events. Conclusion: These drugs are very promising, nonetheless, the unselective approach of applying these monoclonal antibodies may not prove to be cost-effective and potentially exposing some patients to unnecessary side effects.

Abstract Background The 2019 ESC guidelines for the management of dyslipidemia even further lowered the LDL-C-target values for the very high-risk population from &lt;70mg/dl to &lt;55mg/dl. Population based studies already had shown that the previous target was difficult to reach. It is yet unclear how many patients in clinical practice might be treated to the new target. Methods The Dyslipidemia International Study (DYSIS II) prospectively collected data of patients with chronic coronary syndromes (CCS) and acute coronary syndromes (ACS) (all on statins) in 18 countries in Europe, the Middle East, South- and East Asia to document patient characteristics, medication and a current lipid profile from 2012 to 2014 under real life conditions in physicians' offices and hospitals. We took these real-life lipid profiles and data on the kind/dose of used statins to estimate how treatment escalation such as changing statin treatment to a high dose (atorvastatin ≥40mg / rosuvastatin≥20mg), adding ezetimibe and adding a PCSK9-inhibitor might help to bring LDL-C-levels to the recommended &lt;55mg/dl target. Results A total of 7,865 patients were enrolled into DYSIS II, 6,794 had CCS and 1,071 ACS. Under the documented statin treatment in DYSIS only 12.7% of patients reached an LDL-C &lt;55mg/dl. Putting all patients on high dose statins in combination with ezetimibe, 64.1% would reach the target. If PCSK9-inhibitors would be used in the remaining patients not at goal a total of 94.0% would match the goal. Conclusion Our analysis indicates that in real life practice the use available lipid-lowering medications would substantially increase the percentage of CCS- and ACS-patients reaching the newly recommended 2019 ESC guideline LDL-C-target of &lt;55 mg/dl from less than 20% to more than 90% of the population.

Abstract Background The lipid-lowering and positive cardiovascular effect of proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors was shown in several studies, hence, they are more widely used in the lipid-lowering management of individuals with high cardiovascular risk. As real-world data are still scarce, specifically in patients with type 2 diabetes (T2D), the aim of this retrospective analysis was to investigate the efficacy of PCSK9 inhibitors in lowering low-density lipoprotein cholesterol (LDL-C) in an outpatient clinic of a tertiary care center in routine care. Methods A retrospective analysis of data extracted from the electronic patient record was performed. Patients who were routinely prescribed with PCSK9 inhibitor therapy (alirocumab or evolocumab) during the years 2016 and 2019 were included in the analysis. Characteristics of the patient population, the effects on LDL-C and HbA1c levels as well as subsequent cardiovascular events were assessed over an observation period of 18 months. Results We identified 237 patients treated with PCSK9 inhibitors between January 2016 and September 2019. Almost all patients (97.5%) received PCSK9 inhibitors for secondary prevention. 26.2% of the population had a concomitant diabetes diagnosis. Intolerance to statins (83.1%), ezetimibe (44.7%) or both agents (42.6%) was reported frequently. Three months after initiation of PCSK9 inhibitor therapy, 61.2% of the patients achieved LDL-C levels < 70 mg/dl, and 44.1% LDL-C levels < 55 mg/dl. The median LDL-C was lowered from 141 mg/dl at baseline, to 60 mg/dl after 3 months and 66 mg/dl after 12 months indicating a reduction of LDL-C as follows: 57.5% after 3 months and 53.6% after 12 months. After 3 months of observation, target achievement of LDL-C was higher in patients with T2D compared to non-diabetes patients; < 55 mg/dl: 51% vs. 41.5%; < 70 mg/dl 69.4 vs. 58.5%. After 12 months even more pronounced target LDL achievement in T2D was demonstrated < 55 mg/dl: 58.8% vs. 30.1%; < 70 mg/dl 70.6 vs. 49.6%. Patients with insufficiently controlled T2D (HbA1c > 54 mmol/mol) had a higher reduction in LDL-C but still were more likely to subsequent cardiovascular events. Conclusions Significant reductions in LDL-C and a high percentage of patients achieving recommended treatment targets were observed. The percentage of patients with T2D meeting recommended LDL-C targets was higher than in those without T2D. Still some patients did not achieve LDL-C levels as recommended in current guidelines. Special attention to the characteristics of these patients is required in the future to enable achievement of treatment goals and avoid adverse cardiovascular outcomes.
