Abstract 10426: One Year Impact of the 2013 Cholesterol Guidelines on Patterns of Lipid Lowering Treatment

Background: In 2013, national organizations issued new cholesterol guidelines to emphasize evidence-based treatment with moderate- to high-dose statins for patients at high risk for atherosclerotic cardiovascular disease (ASCVD), which includes coronary heart disease, stroke, and peripheral arterial disease. Whether these new guidelines have influenced patterns of treatment one year after their dissemination is unknown. Methods: Using pharmacy and medical claims from a large U.S. health insurance organization, we identified 610,535 adult patients with ASCVD (n=301,440) or diabetes mellitus (n=309,095) and examined statin treatment rates before and one year after the new cholesterol guidelines. Among patients receiving statins post-guidelines, we also evaluated whether patients were treated with guideline-recommended intensity of statin therapy. A standardized difference (SD) of at least 10% was required to declare the effect size meaningful. Results: Overall, there was no change in statin treatment rates for patients with ASCVD (48.0% before guidelines vs. 47.3% after, SD [1.4]) or diabetes (50% vs. 51.5% after, SD [2.4]). Statin initiation rates among patients not on statins pre-guidelines were 10.1% in patients with ASCVD and 14.3% in patients with diabetes, and these gains were offset by 13.0% and 12.2% statin discontinuation rates among ASCVD and diabetes patients, respectively. Among patients taking statins one year post-guidelines, 80% of patients with ASCVD and < 75 years of age were not on guideline-recommended high-intensity statin therapy, whereas >75% of patients with ASCVD and >75 years of age or patients with diabetes were on moderate- or high-intensity statin treatment. Conclusion: One year after dissemination of the new 2013 cholesterol guidelines, overall treatment rates with statins among patients with ASCVD and diabetes have not changed appreciably, and many patients remain either untreated or under-treated.

Current Guidelines

The focus of 2013 cholesterol guidelines to prevent atherosclerotic cardiovascular disease (ASCVD) released by American College of Cardiology (ACC) and American Heart Association (AHA) is the administration of high intensity statin therapy to specific four groups of patients, which were found to benefit the most from such therapy. They no longer promote achieving specific LDL-C goals with a combination therapy involving statins and other drugs, as advocated by the former ATP-III guidelines as well as current guidelines of European Atherosclerosis Society, International Atherosclerosis Society or National Lipid Association. Such approach has been dictated by the strict reliance on randomized controlled trials as the only acceptable level of evidence. However, since publication of the 2013 ACC/AHA guidelines, cardiovascular benefits of ezetimibe added to statin therapy have been established. Moreover, the advent of PCSK9 inhibitors, providing a powerful supplement and/or alternative to statin therapy, further complicates the therapeutic horizon in dyslipdiemias. It is very likely that a new set of ACC/AHA guidelines will be published in 2016, with a return of specific LDL-C and Non-HDL-C goals of therapy as well as integration of drugs other than statins. As the treatment of dyslipidemias becomes more complex, the need for the subspecialty of clinical lipidology to be officially recognized becomes more evident.

Introduction: Appropriate lipid-lowering therapies are essential for the primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD). The aim of this study is to identify discrepancies between cholesterol management guidelines and current practice in an underserved population, with a focus on statin treatment. Methods: We reviewed the records of 1,042 consecutive patients seen between August 2018 and August 2019 in an outpatient academic primary care clinic. Eligibility for statin and other lipid-lowering therapies was determined based on the 2018 American Heart Association and American College of Cardiology (AHA/ACC) guideline on the management of blood cholesterol. Results: Among 464 statin-eligible patients, age was 61.1 +/- 10.4 years and 53.9% were female. Most patients were Black (47.2%), followed by Hispanic (45.7%), and White (5.0%). Overall, 82.1% of patients were prescribed a statin. Statin-eligible patients who qualified based only on a 10-year ASCVD risk > 7.5% were less likely to be prescribed a statin (32.8%, p<0.001). After adjustment for gender and health insurance status, appropriate statin treatment was independently associated with age > 55 years (OR = 4.59 [95% CI 1.09 - 16.66], p = 0.026), hypertension (OR = 2.38 [95% CI 1.29 - 4.38], p = 0.005) and chronic kidney disease (OR = 3.95 [95% CI 1.42 - 14.30], p = 0.017). Factors independently associated with statin undertreatment were Black race (OR = 0.42 [95% CI 0.23 - 0.77], p = 0.005), and statin-eligibility based solely on an elevated 10-year ASCVD risk (OR = 0.14 [95% CI 0.07 - 0.25], p < 0.001). Hispanic patients were more likely to be on appropriate statin therapy when compared to Black patients (86.8% vs 77.2%). Conclusion: Statin underprescription is seen in approximately one out of five eligible patients, and is independently associated with Black race, younger age, fewer comorbidities, and eligibility via 10-year ASCVD risk only. Hispanic patients are more likely to be on appropriate statin therapy compared to Black patients.

Testing Patterns

Background: In a significant update, the 2013 ACC/AHA cholesterol guidelines recommend fixed-dose statin therapy for those at risk and do not recommend non-statin therapies or treatment to target LDL-C levels, limiting the need for repeated LDL-C testing. We examined the implications of these updated guidelines on current lipid treatment and testing patterns in a national registry of cardiology practices. Methods: Using NCDR® PINNACLE Registry® data from 2008 to 2012, we assessed current practice patterns as a function of the 2013 cholesterol guidelines. Lipid-lowering therapies and LDL-C testing patterns by patient risk group (atherosclerotic cardiovascular disease (ASCVD), diabetes, off-treatment LDL-C ≥190mg/dL, or an estimated 10-year ASCVD risk ≥7.5%) were described. Results: Among a cohort of 1,174,545 patients, 1,129,205 (96.1%) were statin-eligible (91.2% ASCVD, 6.6% diabetes, 0.3% off-treatment LDL-C ≥190mg/dL, 1.9% estimated 10-year ASCVD risk ≥7.5%). 377,311 (32.4%) patients were not receiving statin therapy and 259,143 (22.6%) were receiving non-statin therapies. 20.8% patients had 2 or more LDL-C assessments during the study period, and 7.0% had more than 4 assessments. Conclusions: In U.S. cardiovascular practices, 32.4% of statin-eligible patients, as defined by the 2013 ACC/AHA cholesterol guidelines, were not currently receiving them. In addition, 22.6% were receiving non-statin lipid-lowering therapies and 20.8% had repeated LDL-C testing. Achieving concordance with the new cholesterol guidelines would result in significant increases in statin use, as well as significant reductions in non-statin therapies and laboratory testing.

Lipid-lowering therapies are essential for the primary and secondary prevention of atherosclerotic cardiovascular disease (ASCVD). The aim of this study is to identify discrepancies between cholesterol management guidelines and current practice with a focus on statin treatment in an underserved population based in a large single urban medical center. Among 1042 reviewed records, we identified 464 statin-eligible patients. Age was 61.0 ± 10.4 years and 53.9% were female. Most patients were black (47.2%), followed by Hispanic (45.7%) and white (5.0%). In total, 82.1% of patients were prescribed a statin. An appropriate statin was not prescribed in 32.4% of statin-eligible patients who qualified based only on a 10-year ASCVD risk of ≥7.5%.

Abstract Introduction Dyslipidemia is widely prevalent. Despite guidelines that recommend statin therapy for high-risk patients, many of these patents are untreated. This gap in care must be urgently closed. Purpose We analyzed data from the National Health and Nutrition Examination Survey (NHANES) in order to: (1) ascertain the number of high-risk individuals with dyslipidaemia not receiving lipid lowering therapy in the United States; and (2) estimate the reduction in acute cardiovascular (CV) events if those individuals were treated with either moderate or high potency statins in order to achieve at minimum a 30% or 50% reduction in LDL-C levels. Methods Data from NHANES participants who had fasting blood serum data available, including lipids, were included in our analysis (n=14,888). Statistical analyses were performed in the R language. Coronary heart disease (CHD) risk was assessed using NCEP ATP III criteria, and participants were categorized as being at high, intermediate, or low CHD risk. Data from seven surveys from 2003–4 to 2015–6 was used and extrapolations to the US adult population (50 states plus the District of Columbia) were performed using the direct method to the US Census 2000 population. Results We identified 1162 adults (age 20–79) who were high-risk and untreated despite being hyperlipidaemic (LDLC ≥100mg/dL). We estimated they represent 12.8 million individuals in the US 2015–16 population. Without lipid modification and hypothecating 10-year risks of CV events in this group of 20, 25, 30, 35 and 40%, respectively, predicted numbers of CV events are 2.6M, 3.2M, 3.9M, 4.5M, and 5.1M. Moderate-intensity statins reduce LDLC by 30–40% and high-intensity statins by 50–60%. Using untreated LDL-C values from all NHANES surveys we calculated predicted absolute reductions in LDL-C would be at least 42 mg/dL if a moderate-intensity statin was used and at least 70 mg/dL if a high-intensity statin was used, with reductions in CV risk of at least 27% and 46%, respectively. In this group of untreated high-risk individuals, predicted numbers of CV events that could be prevented by moderate-intensity statin for 10 years range from at least 0.7M to at least 1.4M, and with high-intensity statin use for 10 years from at least 1.2M to at least 2.3M, depending on the level of untreated risk. With Numbers Needed to Treat (NTT) between 5 and 18, use of statin treatment in this group would be highly beneficial and cost-effective. Conclusions There are a large number of untreated high-risk individuals with dyslipidaemia in the US. Use of moderate and high dose statin therapy in these patients for 10 years would reduce CV risk by at least 27% and 47%, respectively. Among untreated high-risk patients, the NNTs for moderate and high dose statin therapy are 9–18 and 5–11, respectively, depending on 10-year level of CV risk. The quality of life and socioeconomic implications of these estimates are substantial. Funding Acknowledgement Type of funding source: None

Patients With Diabetes

Background: Diabetic dyslipidemia has specifics that differ from dyslipidemia in patients without diabetes, which contributes to accelerated atherosclerosis equally as dysglycemia. The aim of this study was to deduce the interdependence of diabetic dyslipidemia and cardiovascular diseases (CVD), therapeutic strategies and the risk of diabetes development with statin therapy. Method: We conducted a literature review of English articles through PubMed, PubMed Central and Cochrane, on the role of diabetic dyslipidemia in atherosclerosis, the antilipemic treatment with statins, and the role of statin therapy in newly developed diabetes, by using key words: atherosclerosis, diabetes mellitus, diabetic dyslipidemia, CVD, statins, nicotinic acid, fibrates, PCSK9 inhibitors. Results: hyperglycemia and dyslipidemia cannot be treated separately in patients with diabetes. It seems that dyslipidemia plays one of the key roles in the development of atherosclerosis. High levels of TG, decreased levels of HDL-C and increased levels of small dense LDL- C particles in the systemic circulation are the most specific attributes of diabetic dyslipidemia, all of which originate from an inflated flux of free fatty acids occurring due to the preceding resistance to insulin, and exacerbated by elevated levels of inflammatory adipokines. Statins are a fundamental treatment for diabetic dyslipidemia, both for dyslipidemia and for CVD prevention. The use of statin treatment with high intensity is endorsed for all diabetes-and-CVD patients, while a moderate - intensity treatment can be applied to patients with diabetes, having additional risk factors for CVD. Statins alone are thought to possess a small, although of statistical significance, risk of incident diabetes, outweighed by their benefits. Conclusion: As important as hyperglycemia and glycoregulation are in CVD development in patients with diabetes, diabetic dyslipidemia plays an even more important role. Statins remain the cornerstone of antilipemic treatment in diabetic dyslipidemia, and their protective effects in CVD progression overcome the risk of statin- associated incident diabetes.

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 <70mg/dl to <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 <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 <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 <55 mg/dl from less than 20% to more than 90% of the population.

Statin Use

Background: The 2013 Cholesterol Guidelines include a new atherosclerotic cardiovascular disease (ASCVD) risk calculator that determines the 10-year risk of coronary heart disease and/or stroke. The applicability of this calculator and its predecessor, the Framingham risk score (FRS) in Adult Treatment Panel (ATP) III, has been limited in patients with HIV. The objective of this study was to compare the risk scores of ASCVD and FRS in the initiation of statin therapy in patients with HIV. Methods: We conducted a retrospective chart review of patients with HIV on statin therapy from October 1, 2013, to April 1, 2014. Data collection included patient demographics, pertinent laboratory test results, and medication list. The primary end point evaluated the level of agreement between the guidelines. Results: Of 155 patients who met the inclusion criteria, 116 were treated similarly with both guidelines. This showed a moderate level of agreement ( P < .001). Forty-eight of 86 patients requiring statins were placed on the correct intensity statin using the 2013 guidelines. Regardless of which guideline, a majority of patients required statin therapy. Conclusion: A moderate agreement was found between both guidelines in terms of statin use when applied to an HIV patient population. Based on the 2013 guidelines and taking into account drug interactions with antiretrovirals, 44.2% of the patients were treated with an incorrect statin intensity.

Care Gaps

Introduction: In the US, LDL-C levels and treatment patterns of patients with familial hypercholesterolemia (FH) – a group prioritized for statin therapy in the 2013 ACC/AHA cholesterol guidelines – remain poorly described. In 2013 the FH Foundation launched the CAscade SCreening for Awareness and DEtection (CASCADE) of FH Registry, the only active US FH patient registry addressing this knowledge gap. Methods: We conducted a 2-year (2013-2015) cross-sectional analysis among 1,295 adults with heterozygous FH enrolled in the CASCADE FH Registry from 10 US lipid clinics. Results: Mean (SD) age at enrollment was 54 (16) years; mean age at FH diagnosis was 45 (19) years; 59% were female; and 80% were white. Mean pretreatment and post-treatment LDL-C levels were 256 (66) and 156 (71) mg/dl, respectively. At enrollment, 43% of patients were taking high-intensity statin therapy; 25% were not taking a statin; and 45% received >1 LDL-lowering therapy. Among FH patients on LDL-lowering therapy, 25% achieved an LDL-C <100 mg/dl, and 41% achieved a ≥50% LDL-C reduction (Table). Factors associated with a ≥50% LDL-C reduction included high-intensity statin use (adjusted OR 2.24, 95% CI 1.47-3.42) and use of >1 LDL-lowering therapy (1.94, 1.29-2.93) (Figure). Atherosclerotic cardiovascular disease (ASCVD) was present in 37%, of whom 44% achieved a ≥50% LDL-C reduction and 9% achieved an LDL-C <70 mg/dl. Conclusions: Despite the high prevalence of ASCVD, several care gaps exist for FH patients enrolled in the CASCADE US registry: lack of early diagnosis, insufficient use of high-intensity statin therapy, and failure to achieve adequate LDL-C reductions.

Background: High-intensity statin therapy is recommended in patients with clinical atherosclerotic cardiovascular disease (ASCVD) or at high risk of ASCVD. Current evidence demonstrates efficacy of high-intensity statin therapy in reducing major adverse cardiovascular events; yet the comparative safety profile between high-intensity statin agents remains unknown. In 2011, when atorvastatin became generic, the Veteran’s Health Administration made the formulary switch from rosuvastatin to atorvastatin. Currently, rosuvastatin is generic; however, at the time of this study, it was still under patent. Objective: The primary objective was to determine if high-intensity atorvastatin compared with rosuvastatin is associated with an increased incidence of adverse drug reactions (ADRs) in the veteran population. Methods: A retrospective cohort study at James A. Haley Veterans’ Hospital compared patients receiving rosuvastatin 20 to 40mg from January 2009 to November 2011 (n = 4,165) and atorvastatin 40 to 80mg from May 2012 to June 2016 (n = 5,852). Patients were excluded if they were nonadherent to statin therapy or had a documented ADR to atorvastatin prior to formulary switch. Results: A difference in overall ADR rates was found between atorvastatin and rosuvastatin groups (4.59% vs 2.91%; odds ratio [OR], 1.61; 95% CI, 1.29 to 2.00; P < 0.05). Statistically significant differences in abnormal liver transaminases (3.99% vs 1.39%; OR, 2.95; 95% CI, 2.21 to 3.94; P < 0.05) and statin-associated muscle symptoms (1.14% vs 0.5%; OR, 2.29; 95% CI, 1.39 to 3.74; P < 0.05) were identified between groups. Patients receiving rosuvastatin were on therapy 2.5 times longer before developing an ADR. Conclusion and Relevance: High-intensity atorvastatin compared with rosuvastatin is associated with an increased incidence of ADRs.
