Abstract Introduction Several studies have investigated the association between non-statin lipid-lowering therapy and regression of atherosclerosis. However, the studies were mostly small and their results were not always robust. Objectives (1) to define if a dual lipid-lowering therapy (statin ± non-statin drugs) is associated with coronary atherosclerosis regression, estimated by intravascular ultrasound (IVUS); (2) to assess the association between dual lipid-lowering-induced changes in LDL-C and non-HDL-C levels and atherosclerosis regression. Methods We performed a meta-analysis including trials of non-statin lipid-lowering therapy, reporting C-LDL, non-HDL-C and total atheroma volume (TAV) with a minimum of 6 months of follow-up. The primary endpoint was defined as the change in TAV measured from baseline to follow-up, comparing groups of subjects on statins alone versus combination of statin and non-statin drugs. The random-effects model and meta-regression were performed. Results Eight eligible trials of non-statin lipid-lowering drugs (1759 patients) were included. Overall, the dual lipid-lowering therapy was associated with a significant reduction in TAV [−3.5 mm3 (95% CI: −4.5 to −2.6)]; I2=11%]. In the analysis stratified according to the lipid-lowering drug class (ezetimibe or PCSK9 inhibitors), the findings were similar. In a meta-regression, a 10% decrease in LDL-C or non-HDL-C levels, was associated, respectively, with 0.92 mm3 and 1.05 mm3 regressions in TAV. Conclusion Our data suggest the addition of ezetimibe or PCSK9 inhibitors to statin therapy results in significantly increased regression of TAV. When the LDL-C and non-HDL-C levels reached were lower, the observed effect was also greater. Forest Plot by Drugs Group Funding Acknowledgement Type of funding source: None

Abstract Background Lipid lowering therapy may be associated with impaired cognitive function. The association between the use of Proprotein Convertase Subtilisin/Kexin Type 9 (PCSK9) inhibitors and the risk of neurocognitive adverse effects remains unclear. Purpose To assess the neurocognitive safety of PCSK9 inhibitors using meta-analysis and meta-regression of randomized controlled trials (RCTs). Methods PubMed (MEDLINE), Embase and Cochrane library were searched. RCTs that reported assessments of neurocognitive outcomes of participants using PCSK9 inhibitors, with a duration of follow up of at least six months were included. The results of the search were screened by two independent reviewers. Any disagreements were resolved by consensus. The research was conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension statement for meta-analyses. Results were pooled using random-effects models. The primary safety outcome of this analysis was defined as the reported incidence of neurocognitive adverse effects. Results Results of 21 trials were included in the analysis. Among 59,733 patients, 31,611 were treated with PCSK9 inhibitors. No significant difference in the incidence of neurocognitive side effects between the treatment and control groups was identified (RR=1.01, 95% CI: 0.86–1.19, I2=3%). Same results were seen in separate analysis for each of the medicines (Alirocumab- RR=0.88, 95% CI: 0.72–1.08, I2=0%, Evolocumab- RR=1.42, 95% CI: 0.74–2.73, I2=55%). In a meta-regression analysis there was no statistically significant association between the assessed and the risk for neurocognitive side effects. Conclusions Pooled results of our meta-analysis and meta-regression clearly show that the exposure to PCSK9 inhibitors is not associated with an increased risk of neurocognitive adverse events. Due to the increasing proportion of patients using lipid-lowering therapy these results are positively reassuring. However, more data from long-term outcomes studies is needed to further evaluate the effect of longer exposure to PCSK9 inhibitors Funding Acknowledgement Type of funding source: None

Abstract Background In the current guideline of the ESC, in patients with very high cardiovascular risk such as coronary heart disease (CHD) a treatment target for LDL-C <1.4mmol/l and/or a halving of the initial value are defined. It is unclear whether these treatment targets are achievable with standard therapy including statins and/or ezetemibe. Methods The primary objective of this prospective, multi-centre register study was the question of the guidance-based adaptation and adherence to lipid-lowering therapy during and after a cardiac rehabilitation in 1,100 patients with CHD up to 12 months after discharge from the six rehabilitation clinics involved. Patients were included from 2016 to 2018. Results The median age of the 1,100 patients was 63.4±10.4 years, the mean BMI was 28.5±4.7kg/m2, and 24.1% of patients were female. 12.2% were active smokers, 91.6% reported dyslipoproteinemia, 33.9% suffered from diabetes mellitus and 86.5% from hypertension. The majority of patients were included with the main indications NSTEMI (31.6%), STEMI (29.6%) and after CABG surgery (26.4%). The proportion of patients treated with statins was more than 94% when admitted and discharged from the rehabilitation clinic, as well as in 3- and 12-months follow-ups. Approximately 9% of patients were treated with ezetemibe at baseline. On discharge from the rehabilitation clinic 23% of patients were treated with ezetemibe, which remains stable at 3 and 12 months. PCSK9 inhibitors were used in 0.1–0.3% of patients at all times. The adjustment of LLT during three week cardiac rehabilitation resulted in median LDL-C values of 2.27mmol/l (1.80/2.84) at baseline, 1.97mmol/l (1.57/2.47) on discharge (p<0.001 compared to baseline), 1.94mmol/l (1.57/2.49) after three months and 1.94mmol/l (1.53/2.40) after 12 months. The proportion of patients with LDL-C <1.4mmol/l was 9% at baseline, 15.7% on discharge (p<0.001 compared to baseline), 15.6% at three-month follow-up and 15.1% at 12-month follow-up (Figure 1). Discussion In the context of cardiac rehabilitation, an effective adjustment of LLT is carried out, which resulted in a significant reduction of LDL-C. However, despite a high percentage of patients on statins and ezetemibe, the proportion of patients in the new target range <1.4mmol/l was only achievable in a small percentage and the question arises whether these treatment targets can be achieved without additional administration of PCSK9 inhibitors in majority of patients with CHD.

AbstractTo assess the influence of lipid-lowering therapy on coronary plaque volume, and to identify the LDL and HDL targets for plaque regression to provide a comprehensive overview. The databases searched (from inception to 15 July 2020) to identify prospective studies investigating the impact of lipid-lowering therapy on coronary plaque volume and including quantitative measurement of plaque volume by intravascular ultrasound after treatment. Thirty-one studies that included 4997 patients were selected in the final analysis. Patients had significantly lower TAV (SMD: 0.123 mm3; 95% CI 0.059, 0.187; P = 0.000) and PAV (SMD: 0.123%; 95% CI 0.035, 0.212; P = 0.006) at follow-up. According to the subgroup analyses, TAV was significantly reduced in the LDL < 80 mg/dL and HDL > 45 mg/dL group (SMD: 0.163 mm3; 95% CI 0.092, 0.234; P = 0.000), and PAV was significantly reduced in the LDL < 90 mg/dL and HDL > 45 mg/dL group (SMD: 0.186%; 95% CI 0.081, 0.291; P = 0.001).Thirty-one studies that included 4997 patients were selected in the final analysis. Patients had significantly lower TAV (SMD: 0.123 mm3; 95% CI 0.059, 0.187; P = 0.000) and PAV (SMD: 0.123%; 95% CI 0.035, 0.212; P = 0.006) at follow-up. According to the subgroup analyses, TAV was significantly reduced in the LDL < 80 mg/dL and HDL > 45 mg/dL group (SMD: 0.163 mm3; 95% CI 0.092, 0.234; P = 0.000), and PAV was significantly reduced in the LDL < 90 mg/dL and HDL > 45 mg/dL group (SMD: 0.186%; 95% CI 0.081, 0.291; P = 0.001). Our meta-analysis suggests that not only should LDL be reduced to a target level of < 80 mg/dL, but HDL should be increased to a target level of > 45 mg/dL to regress coronary plaques.Trial Registration PROSPERO identifier: CRD42019146170.

Abstract Aims To estimate the proportion of patients with a recent myocardial infarction (MI) who would be eligible for additional lipid-lowering therapy according to the 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) guidelines for the management of dyslipidaemias, and to simulate the effects of expanded lipid-lowering therapy on attainment of the low-density lipoprotein cholesterol (LDL-C) target as recommended by the guidelines. Methods and results Using the nationwide SWEDEHEART register, we included 25 466 patients who had attended a follow-up visit 6–10 weeks after an MI event, 2013–17. While most patients (86.6%) were receiving high-intensity statins, 82.9% of the patients would be eligible for expanded lipid-lowering therapy, as they had not attained the target of an LDL-C level of &lt;1.4 mmol and a ≥50% LDL-C level reduction. When maximized use of high-intensity statins followed by add-on therapy with ezetimibe was simulated using a Monte Carlo model, the LDL-C target was reached in 19.9% using high-intensity statin monotherapy and in another 28.5% with high-intensity statins and ezetimibe, while 50.7% would still be eligible for proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors. When use of alirocumab or evolocumab was simulated in those who were eligible for PCSK9 inhibitors, around 90% of all patients attained the LDL-C target. Conclusion  Our study suggests that, even with maximized use of high-intensity statins and ezetimibe, around half of patients with MI would be eligible for treatment with PCSK9 inhibitors according to the 2019 ESC/EAS guidelines. Considering the current cost of PCSK9 inhibitors, the financial implications of the new guidelines may be substantial.
