Background: Although current cholesterol performance measures define good quality as low density lipoprotein cholesterol (LDL-C) levels < 100mg/dl in cardiovascular disease (CVD) patients, they provide a snap shot at one time point and do not inform whether an appropriate action was taken to manage elevated LDL-C levels. We assessed frequency and predictors of this appropriate response (AR). Methods: We used administrative data to assess 22,902 CVD patients receiving care in a Veterans Affairs network of 7 hospitals and affiliated clinics. We determined the proportion of CVD patients at LDL-C goal <100 mg/dl, and the proportion of patients with uncontrolled LDL-C levels (>100 mg/dl) who had an AR [defined as the initiation or dosage increase of a lipid lowering medication (LLM), addition of a new LLM, receipt of maximum dosage or >1 LLM, or LDL-C reading <100 mg/dl] at 45 days follow-up. Logistic regression was performed to evaluate facility, provider and patient characteristics associated with AR. Results: LDL-C levels were at goal in 16,350 (71.4%) patients. An additional 2,110 (9.2%) had an AR at 45 days of follow-up. Controlling for clustering between facilities and patient's illness severity, history of diabetes (OR 1.18, 95% CI 1.03-1.35), hypertension (OR 1.21, 95% CI 1.02-1.44), patients showing good medication adherence (medication possession ratio > 0.8) [OR 2.29, 95% CI 1.99-2.64] were associated with AR. Older CVD patients (age >75 years) were less likely to receive AR (OR 0.60, 95% CI 0.52-0.70). Teaching vs. non-teaching facility (p=0.40), physician vs. non-physician provider (p=0.14), specialist vs. non-specialist primary care provider (p=0.12), and patient's race (p=0.12) were not predictors of AR. Conclusion: Among patients with CVD and LDL-C above guideline recommended levels, only one-third receive AR. Diabetic and hypertensive CVD patients are more likely to receive AR, whereas older Veterans with CVD receive AR less often likely reflecting providers' belief of lack of efficacy from treatment intensification in older CVD patients. Our findings are important for quality improvement and policy making initiatives as they provide more actionable information compared with isolated LDL-C goal attainment as a quality indicator.

Background: Many patients with hypercholesterolemia and/or cardiovascular disease are unable to achieve sufficient low-density lipoprotein cholesterol (LDL-C) reduction with statins alone (or are statin intolerant). This is increasingly the case with clinical guidelines recommending that lower LDL-C levels are beneficial for patients. This network meta-analysis (NMA) assessed the relative efficacy of lipid lowering therapies (LLTs) added to statins for reducing LDL-C. Methods: A systematic review of randomized controlled clinical trials to May 2020 identified 48 studies for inclusion in the primary NMA. The primary NMA included studies ≥12 weeks duration in which alirocumab, bempedoic acid, evolocumab, ezetimibe, or inclisiran were added to moderate-high intensity statins (or lower intensity / no statin in statin intolerant patients). Random effects NMA was used to analyse % change in LDL-C to compare the treatment effects indirectly. Results: Over 12 weeks, all non-statin LLTs significantly reduced LDL-C from baseline versus placebo. Evolocumab 140 mg Q2W / 420 mg QM and alirocumab 150 mg Q2W were associated with largest LDL-C reductions, which were greater than those achieved with lower/alternative doses of alirocumab, bempedoic acid (± ezetimibe), ezetimibe and inclisiran (Table). Consistent results were observed in sensitivity analyses to address heterogeneity (excluding familial hypercholesterolemia and east Asian studies), in the subgroup NMA of studies in predominantly atherosclerotic cardiovascular disease patients, and in the statin intolerant subgroup NMA. Conclusions: All agents reduced LDL-C, however, the PCSK9 inhibitors evolocumab 140 mg Q2W / 420 mg QM and alirocumab 150 mg Q2W were the most effective LLT regimens for reducing LDL-C when added to statins.

Abstract BackgroundPrevious studies, in which the data were collected about half a century ago, suggested that elevated low density lipoprotein cholesterol (LDL-C) is not associated with increased risk of cardiovascular disease (CVD) in patients over 70 years old. However, what is the relationship between LDL-C and CVD risk in a contemporary population aged over 70 years has not been well examined in China.MethodsThe China Health and Retirement Longitudinal Study (CHARLS) is an ongoing nationally representative study. In this analysis, participants of CHARLS who did not taking statins and did not have heart disease and stroke at 2011 were include and were followed up to 2018. The outcome of this analysis was occurrence of CVD at follow up, which include heart disease and stroke. Cox regression was used to assess the harmful effect of LDL-C on CVD occurrence. We calculated e-values to quantify the effect of unmeasured confounding on our results.ResultsOf the 9,631 participants, 15.2% (N=1,463) were aged over 70 years and 52.5% (N=5,060) were female. During the 7 years follow-up, 1,437 participants had a first CVD attack. Risk of CVD occurrence increased 8% with each 10 mg/mL elevation in LDL-C in whole participants (adjusted HR, 1.08; 95% CI, 1.06-1.10) and age groups of ≥70 years, 60-69years and <60 years. Similar results were observed in subgroup analyses, in which participants were stratified by sex, hypertension, diabetes and chronic kidney disease. According to the restricted cubic spline, we noted a U-shaped relationship between LDL-C and risk of CVD occurrence in group over 70 years old, however, we further found that in the left side of U-shape curve, LDL-C was not associated with occurrence of CVD and its attribution to CVD occurrence was only 2.1%, which indicated that lower level of LDL-C could not increase the risk of CVD occurrence as it was demonstrated by a U-shape association. E-value analysis suggested robustness to unmeasured confounding.ConclusionsIn contemporary society of China, elevated the level of LDL-C also increased the risk of CVD in participants over 70 years old as in the relatively younger participants. These results should strengthen guideline recommendations for the use of lipid lowering therapies in those elderly.

We aimed to test the association between low-density lipoprotein cholesterol (LDL-C) and cardiovascular disease (CVD), cancer, and all-cause mortality in non-statin users. A total of 347,971 subjects in Kangbuk Samsung Health Study (KSHS.57.4% men, mean follow up: 5.64 ± 3.27 years) were tested. To validate these associations, we analyzed data from another cohort (Korean genome and epidemiology study, KoGES, 182,943 subjects). All subjects treated with any lipid-lowering therapy and who died during the first 3 years of follow up were excluded. Five groups were defined according to baseline LDL-C concentration (<70, 70–99, 100–129, 130–159, ≥160 mg/dL). A total of 2028 deaths occurred during follow-up in KSHS. The lowest LDL-C group (LDL < 70 mg/dL) had a higher risk of all-cause mortality (HR 1.95, 1.55–2.47), CVD mortality (HR 2.02, 1.11–3.64), and cancer mortality (HR 2.06, 1.46–2.90) compared to the reference group (LDL 120–139 mg/dL). In the validation cohort, 2338 deaths occurred during follow-up. The lowest LDL-C group (LDL < 70 mg/dL) had a higher risk of all-cause mortality (HR 1.81, 1.44–2.28) compared to the reference group. Low levels of LDL-C concentration are strongly and independently associated with increased risk of cancer, CVD, and all-cause mortality. These findings suggest that more attention is needed for subjects with no statin-induced decrease in LDL-C concentrations.

Background We studied care gap in patients with familial hypercholesterolemia (FH) with respect to lipid‐lowering therapy. Methods and Results We enrolled patients with cardiovascular disease (CVD) or FH and low‐density lipoprotein‐cholesterol >2.0 mmol/L despite maximally tolerated statin therapy. During follow‐up physicians received online reminders of treatment recommendations of 2009 patients (median age, 63 years, 42% women), 52.4% had CVD only, 31.7% FH only, and 15.9% both CVD and FH. Patients with FH were younger and more likely to be women and non‐White with significantly higher baseline low‐density lipoprotein‐cholesterol level (mmol/L) as compared with patients with CVD (FH 3.92±1.48 versus CVD 2.96±0.94, P <0.0001). Patients with FH received less statin (70.6% versus 79.2%, P =0.0001) at baseline but not ezetimibe (28.1% versus 20.4%, P =0.0003). Among patients with FH only, 45.3% were at low‐density lipoprotein target (≥ 50% reduction from pre‐treatment level or low‐density lipoprotein <2.5 mmol/L) at baseline and increasing to 65.8% and 73.6% by visit 2 and 3, respectively. Among patients with CVD only, none were at recommended level (≤2.0 mmol/L) at baseline and 44.3% and 53.3% were at recommended level on second and third visit, respectively. When primary end point was analyzed as a difference between baseline and last available follow‐up observation, only 22.0% of patients with FH only achieved it as compared with 45.8% with CVD only ( P <0.0001) and 55.2% with both FH+CVD ( P <0.0001). Conclusions There is significant treatment inertia in patients with FH including those with CVD. Education focused on patients with FH should continue to be undertaken.

Abstract Background/Introduction Limited real-world data are available on attainment of low-density lipoprotein cholesterol (LDL-C) treatment goals in patients with atherosclerotic cardiovascular disease (ASCVD) in Canada. Purpose A retrospective observational study was conducted to describe types of ASCVD events/procedures, time between events and use of lipid lowering treatment (LLT) in patients who did not achieve LDL-C goal. Methods Patients in Ontario ≥65 years with a primary ASCVD event/procedure between 1 Apr 2005 and 31 Mar 2016, treated with an LLT and with index and follow up LDL-C values were identified from claims data at the Institute for Clinical Evaluative Sciences data repository. Patients were assessed over a 1-year follow up period for LDL-C goal attainment (&lt;2.0 mmol/L or 50% reduction from index LDL-C) and analysed by LLT and by index event type. Results Overall, 28% of 143,302 patients ≥65 years on LLT failed to attain LDL-C goal at follow up (Figure). The proportion of patients failing to achieve LDL-C goal decreased from 35% to 22% over the 11-year study period. Mean time between index and follow up LDL-C (based on lowest score &gt;2 weeks and up to 1 year after index LDL-C) was 203±97 days. When analysed by low-, moderate- or high-intensity statin, 57%, 30%, and 22% of patients failed to achieve LDL-C goal at follow up, respectively. Conclusions In this study, more than 1 in 4 patients with ASCVD in Ontario failed to achieve guideline recommended LDL-C goal despite treatment. In particular, ∼1 in 3 patients with cerebral and peripheral arterial disease were not at goal. An opportunity exists to better manage these high risk ASCVD patients with further statin intensification and additional LLTs This study made use of de-identified data from the ICES Data Repository, which is managed by the Institute for Clinical Evaluative Sciences with support from its funders and partners: Canada's Strategy for Patient-Oriented Research (SPOR), the Ontario SPOR Support Unit, the Canadian Institutes of Health Research and the Government of Ontario.

Aims The 2018 American College of Cardiology (ACC)/American Heart Association (AHA) and 2019 European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS) lipid guidelines recently updated their recommendations regarding proprotein convertase subtilisin/kexin-9 inhibitors (PCSK9i). We assessed the potential eligibility for PCSK9i according to the new guidelines in patients with acute coronary syndromes. Methods and results We analysed a contemporary, prospective Swiss cohort of patients hospitalised for acute coronary syndromes. We modelled a statin intensification effect and an incremental ezetimibe effect on low-density lipoprotein-cholesterol levels among patients who were not on high-intensity statins or ezetimibe. One year after the index acute coronary syndrome event, treatment eligibility for PCSK9i was defined as low-density lipoprotein-cholesterol of 1.4 mmol/l or greater according to ESC/EAS guidelines. For ACC/AHA guidelines, treatment eligibility was defined as low-density lipoprotein-cholesterol of 1.8 mmol/l or greater in the presence of very high-risk atherosclerotic cardiovascular disease, defined by multiple major atherosclerotic cardiovascular disease events and/or high-risk conditions. Of 2521 patients, 93.2% were treated with statins (53% high-intensity statins) and 7.3% with ezetimibe at 1 year, and 54.9% had very high-risk atherosclerotic cardiovascular disease. Low-density lipoprotein-cholesterol levels less than 1.8 mmol/l and less than 1.4 mmol/l at 1 year were observed in 37.5% and 15.7% of patients, respectively. After modelling the statin intensification and ezetimibe effects, these numbers increased to 76.1% and 49%, respectively. The proportion of patients eligible for PCSK9i was 51% according to ESC/EAS criteria versus 14% according to ACC/AHA criteria. Conclusions In this analysis, the 2019 ESC/EAS guidelines rendered half of all post-acute coronary syndrome patients potentially eligible for PCSK9i treatment, as compared to a three-fold lower eligibility rate based on the 2018 ACC/AHA guidelines.
