Abstract 4140116: Adherence to Lipid Lowering Therapy among US Veterans with Atherosclerotic Cardiovascular Disease

Introduction/Background: US Veterans experience a high burden of cardiovascular disease (CVD). Improved adherence to lipid-lowering therapy (LLT) is strongly associated with reducing low-density lipoprotein cholesterol (LDL-C), which has the potential to reduce morbidity and mortality among Veterans with atherosclerotic cardiovascular disease (ASCVD). Goals/Aims: To describe adherence to statin and non-statin LLT among US Veterans with ASCVD. Methods/Approach: Using Veterans’ Health Administration (VHA) electronic health records from January 1, 2003, to December 31, 2019, we identified regular users of the VHA who were on at least one LLT within 12-months after ASCVD diagnosis. ASCVD diagnosis was identified using ICD9/10 and Current Procedural Terminology codes. Medication possession ratio (MPR) was calculated as the sum of days’ supply for all fills of a given LLT during 12-, 24-, and 36-month follow-up, divided by the number of days in the follow-up period. Medication adherence was defined as MPR ≥ 0.80. Results/Data (descriptive and inferential statistics): The total number of Veterans on an LLT within 12-months after ASCVD diagnosis was 2,194,684 [mean (SD) age=68 (10) years, 98% male, and 75% white race]. Overall proportion of patients who were adherent to LLT was 68%, 64%, and 62%, at 12-, 24-, and 36-months post ASCVD diagnosis, respectively (Table). Conclusion(s): Suboptimal adherence to LLT was observed in one third of US Veterans with ASCVD. Adherence rates were highest in the first 12 months post ASCVD diagnosis. Future studies are needed to understand factors contributing to low and declining LLT adherence over time among Veterans.

Abstract 4136978: Six-month Changes in Lipid Management in the Veterans Affairs Lipid Optimization Reimagined Quality Improvement (VALOR-QI) Program

Background: US Veterans have a high burden of cardiovascular disease (CVD). While cholesterol management is one of the most effective approaches for reducing CVD burden, over two-thirds of Veterans with atherosclerotic cardiovascular disease (ASCVD) are not optimally managed. Aims: To evaluate LDL-C monitoring, lipid lowering therapy (LLT) use, and LDL-C levels at baseline and six-months for Veterans in the Veterans Affairs Lipid Optimization Reimagined Quality Improvement (VALOR-QI) Program. Methods: VALOR-QI is a national quality improvement collaboration between the US Department of Veterans Affairs and the American Heart Association (AHA) with the goal of improving lipid management among Veterans with ASCVD. To assess and address barriers to achieving optimal lipid levels, Clinical Champions, Health Care Coaches, and participating providers from 50 VA sites work with AHA QI Consultants. Eligible Veterans (those with an ASCVD diagnosis at two outpatient or one inpatient visit or one ASCVD procedure) were considered engaged in VALOR-QI if they had a qualifying appointment with a participating provider during the program. We examined rates of LDL-C monitoring and LLT use at baseline (start of site monitoring) and 6 months after. Among Veterans who were in the program ≥6 months and had >1 LDL-C measure, we investigated percent meeting an LDL-C goal of <70 mg/dL at their first LDL-C (closest to their first visit with priority given to labs within 365 days before their first visit) and follow-up LDL-C (closest to 6 months after entering the program) and mean LDL-C change (paired t-test). Results: Six months after starting VALOR-QI, sites had a 41% increase in LDL-C monitoring and a 6% increase in LLT use. Among 29,610 Veterans engaged in the program ≥6 months with at least two lipid labs [mean (SD) age 71.0 (9.3) years, 95% men, 72% white race], the proportion who met the LDL-C goal <70 mg/dL increased from 44% at their first measure to 51% at 6-month follow-up. Among these Veterans, we observed a mean LDL-C decrease of 5.1 mg/dL (95% CI: -5.50, -4.78). Conclusion: We observed an increase in lipid monitoring and LLT use and improved LDL-C at 6-month follow-up among US Veterans engaged in VALOR-QI.

Abstract 4124875: Association between Elevated Lipoprotein(a) and Cardiovascular Events and Mortality in a Nationally Representative Sample of US Medicare, Medicaid, and Commercial Enrollees with ASCVD

Background: Elevated lipoprotein(a) [Lp(a)] is an independent and causal risk driver for atherosclerotic cardiovascular disease (ASCVD). Few patients with ASCVD receive Lp(a) screening and real-world data assessing the association between elevated Lp(a) and risk of cardiovascular (CV) events and mortality is limited. Objectives: To examine the association of elevated Lp(a) and risk of CV events and death in an ASCVD population using large US health claims databases. Methods: Patients with ASCVD were pooled from US Medicare, commercial, and Medicaid health plans from 2017 to 2022. Lp(a) levels were linked at the patient level from HealthVerity Lab Data and categorized as: <30 mg/dL (<75 nmol/L), ≥30-<50 mg/dL ( > 75-<125 nmol/L), ≥50-<70 mg/dL ( > 125-<175 nmol/L), ≥70-<90 mg/dL (≥175-<225 nmol/L) and ≥90 mg/dL (≥225 nmol/L). Patients were followed from the 1 st ASCVD diagnosis (index) to insurance plan disenrollment, death, or end of study. Cox regression, adjusted for age, sex, race, insurance, comorbidities, LDL-C, and other risk factors, measured the association between Lp(a) levels and risk of CV events and death. Results: Of 28.8 million ASCVD patients, 180,240 (0.6%) had Lp(a) levels: mean(±SD) age 68.6±1 years, 50.1% male, 5.9% Black, 2.8% Hispanic, 2.1% Asian, 72.8% Medicare, 21.8% commercial, and 5.4% Medicaid. Mean follow-up was 3.7 years; 23.3% and 15.7% had Lp(a) ≥50mg/dL [≥125 nmol/L] and ≥70 mg/dL (≥175 nmol/L), respectively. Black patients had highest median Lp(a) (50 mg/dL/111 nmol/L), followed by Asian (13.5 mg/dL/35.5 nmol/L), White (13 mg/dL/32 nmol/L), and Hispanic (11.5 mg/dL/29 nmol/L) patients. Lp(a) levels of ≥30-<50 mg/dL, ≥50-<70 mg/dL, ≥70-<90 mg/dL, and ≥90 mg/dL were associated with 7%, 10%, 16%, and 26% greater risks of CV events vs. <30 mg/dL (p-values <0.0001; cumulative incidence reported in Figure 1). All-cause mortality risk was also greater for those with Lp(a) ≥90 mg/dL vs. <30 mg/dL: hazard ratio (HR)=1.11, p=0.003. Similar trends persisted for patients with LDL-C ≤70 mg/dL. Conclusion: In this national-scale real-world cohort of patients with ASCVD, Lp(a) testing is infrequent and elevated Lp(a) levels were significantly associated with a greater risk of CV events and mortality.

Systemic inflammation and risk of death in patients with atherosclerotic cardiovascular disease and chronic kidney disease

Abstract Background Atherosclerotic cardiovascular disease (ASCVD) and chronic kidney disease stage 3 - 4 (CKD) affects 7% and 10% of the Danish population, respectively. Systemic inflammation (SI) contributes to destabilisation of atherosclerotic plaques and is characterized by elevated levels of C-reactive protein (CRP) in the blood. CKD is associated with SI and is independently associated with an increased risk of ASCVD. CRP levels ≥2 mg/L have been identified as a risk factor for mortality and major adverse cardiovascular events (MACE). Purpose To provide real-world evidence on the clinical burden of SI in patients diagnosed with ASCVD and CKD, using national health registers. Method Data from the Danish National Patient Registry from 1994-2022 was used to identify ASCVD patients by ICD-10 codes. CKD was identified by eGFR test results in the range [15 -59mL/min/1.73m2], in the Register of Laboratory Results for Research (RLRR). The latter diagnosis of ASCVD and CKD was set as index date. CRP-test results were extracted from RLRR and only individuals with at least two CRP tests were included. If two CRP-test results ≥2mg/L to < 20mg/L were observed less than six month apart, and within two years of index date, the individual was classified to have SI. The eGFR data from RLRR was available from 2011 onwards, with some regional differences in reporting. Individuals observed with CKD or ASCVD in the first year of eGFR availability were excluded to ensure a study of incident individuals. Individuals using select medications or diagnosed with selected chronic conditions thought to influence CRP levels were excluded. Additional population characteristics were extracted from corresponding national health and administrative registers. Hazard of all-cause mortality and MACE was analysed in a Cox proportional risk regression. Results From 2012 to 2022, a total of 19,162 individuals were eligible for the study population (SI: 13,039, No SI: 6,123). Median follow-up time was 4.1 and 8.2 years for individuals with or without SI, respectively. Median CRP two years before and after index date in the two groups was 7mg/L and 1mg/L. No clinically significant differences were found for demographic or socioeconomic characteristics. Patients with SI had more frequent history of hypertension, atrial fibrillation, COPD, heart failure and Type 2 diabetes before index, and higher risk of hypertension, atrial fibrillation, stroke, heart failure and type 2 diabetes after index. SI population had significantly increased hazard of mortality in a crude model (HR: 2.35, 95% CI: [2.22 – 2.50]), and in adjusted analysis HR: 2.06 ([1.92 - 2.21]). The corresponding hazard ratios for MACE were 1.9 ([1.81 – 2.01]) and 1.66 ([1.57 – 1.77]). The results were consistent across different model specifications and subgroups. Conclusion SI is associated with a significantly higher clinical burden of disease and a higher risk of all-cause mortality.Flowchart of inclusion/exclusionHazard ratio, overall and by subgroup

Twenty-year trends in peripheral artery disease, lower extremity revascularization, and lower extremity amputation in newly diagnosed type 2 diabetes

Abstract Background Trends in risk of lower extremity complications in patients with newly diagnosed type 2 diabetes (T2DM) are largely unexplored. Purpose To examine the 5-year risk trends of peripheral artery disease (PAD), lower extremity revascularization (LER), and lower extremity amputation (LEA) in patients with newly diagnosed T2DM over a 25-year study period. Methods We conducted a cohort study that included all patients in Denmark diagnosed with T2DM from 1996 to 2015, who had no prior hospital diagnosis of atherosclerotic cardiovascular disease. These patients were age- and sex-matched with up to three comparisons from the general population. Individuals were assigned to 5-year calendar periods based on their year of inclusion and were followed for 5 years. The primary outcomes were the 5-year risks of PAD, LER, and LEA. Age- and sex-adjusted hazard ratios (aHR) were computed using Cox regression analysis. Results The study cohort consisted of 288,825 newly diagnosed T2DM patients (52% males; median age 61 years) and 782,232 comparisons from the general population. From 1996-2000 to 2015-2020, the 5-year risk of PAD decreased from 2.2% to 1.2% (aHR 0.56 [95% CI 0.52-0.61]), LER from 0.7% to 0.5% (aHR 0.73 [95% CI 0.63-0.84]), and LEA from 1.0% to 0.4% (aHR 0.44 [95% CI 0.38-0.50]) in T2DM patients (Figure). Compared with the general population, the 5-year risk differences decreased from 1.4% to 0.5% for PAD, from 0.4% to 0.2% for LER, and from 0.8% to 0.3% for LEA. The distribution of LEA types (hip/thigh, knee/lower leg, or ankle/foot/toe amputation) remained largely stable over time in T2DM patients. Use of prophylactic cardiovascular medications in T2DM patients increased notably during the study period, especially use of statins (5% to 50%) and multiple antihypertensive drugs (18% to 33%). Conclusions Over recent decades, the risks of PAD, LER, and LEA have decreased in patients with newly diagnosed T2DM, approaching the risk levels observed in the general population. This coincided with a great increase in use of prophylactic cardiovascular medications among T2DM patients.Trends in lower extremity complications.

Systemic inflammation in patients with atherosclerotic cardiovascular and chronic kidney disease in Spain: a population-based study using electronic medical records from a primary care database

Abstract Background Systemic inflammation (SI) is recognized as a critical driver of atherosclerotic cardiovascular disease (ASCVD), and it is frequently observed in ASCVD patients with comorbid chronic kidney disease (CKD). Elevated C-reactive protein (CRP) levels, a common biomarker for SI, have been associated with poor prognosis in ASCVD and CKD patients, increased risk of major adverse cardiovascular events and renal disease progression, as well as greater mortality. Purpose To estimate the prevalence of SI in patients with ASCVD in Spain overall and by CKD status, and to describe patients’ clinical characteristics. Methods In this population-based observational study, data from THIN Spain, a database of electronic medical records from a large network of general practitioners, were used to identify adult patients with a diagnosis code of ASCVD (atherosclerotic coronary or cerebrovascular event, peripheral arterial disease, or other atherosclerotic vascular event) and ≥1 eligible CRP measurement between January 1st 2014 to July 31st 2023 (latest data available at time of data extraction).[Figure] SI was defined as CRP ≥ 2mg/L. Point prevalence of SI at the end of the study (among patients alive with ≥1 CRP in the prior 18 months) and the proportion of patients with evidence of SI during the study period (2014-2023) were estimated overall and by CKD status (defined as CKD stage 3+, or eGFR <60 mL/min/1.73m², or urinary albumin-to-creatinine ratio ≥30 mg/g). Patients’ comorbidities (defined using primary care diagnoses), and laboratory values were reported by SI status at first CRP measurement during the study period. Results Among 76,423 patients with ASCVD diagnosis, 15,798 patients (20.7%) were included in the study (mean age: 71.1 years; 43% females), of whom 5,111 (34%) had CKD at first eligible CRP (n=975 with unknown CKD status). Mean CRP in ASCVD patients with CKD was 24% higher than in those without CKD (4.36 vs 3.53 mg/L, p<0.001). The proportion of ASCVD patients with SI at first CRP measurement was 58% overall (65% among CKD patients; 55% among patients without CKD; p<0.001). The point prevalence of SI at the end of the study was 56% among ASCVD patients overall (62% among CKD patients; 52% among patients without CKD; p<0.001), while 64% of ASCVD patients had evidence of SI at any time during the study period (72% among CKD patients; 59% among patients without CKD; p<0.001). Compared to ASCVD patients without SI, higher proportion of SI patients were smokers and with comorbidities. Also, ASCVD patients with SI had lower baseline eGFR levels and higher levels of LDL-C and triglycerides than ASCVD patients without SI.[Table] Conclusions SI prevalence is high among patients with ASCVD in Spain, especially among patients with comorbid CKD. Strategies to target SI may have beneficial effects in prevention of cardiovascular events and mortality in ASCVD patients.

Characterization of individuals with atherosclerotic cardiovascular disease, with and without chronic kidney disease: results from a UK electronic health record database

Abstract Introduction Elevated C-reactive protein (CRP) levels are often present in individuals with atherosclerotic cardiovascular disease (ASCVD), including in those who also have chronic kidney disease (CKD), and are associated with an increased risk of major adverse cardiovascular events (MACE). To understand unmet needs in the identification and management of at-risk individuals, we characterized patients with ASCVD in a UK database, according to CKD stage and CRP levels. Methods This study comprised separate retrospective cross-sectional and longitudinal cohort analyses of patients in the Clinical Practice Research Datalink (CPRD) Aurum database, a representative UK database of anonymized primary care records. In the cross-sectional analysis, CPRD Aurum was linked with Hospital Episode Statistics (HES) and Index of Multiple Deprivation data to assess patient characteristics on 1 Jan 2021 (defined as index date). In the cohort analysis, CPRD Aurum was linked with HES and Office for National Statistics mortality data to determine the incidence of 3-point MACE (3P-MACE) over approximately 5 years of follow-up (index date: 1 Jan 2016). Both analyses included individuals ≥ 18 years old with an ASCVD diagnosis in both primary and secondary care in the 5 years pre-index. Data were analysed using descriptive statistics. Patient characteristics were assessed by CKD stage; for individuals with CKD stage 3–4, characteristics were also assessed by CRP levels. Results In total, 225,767 and 230,055 individuals were included in the cross-sectional and cohort analyses, respectively. The prevalence of CKD stage 3–4 among individuals with ASCVD was 24.3% (Table 1). The proportion of individuals with elevated CRP (CRP ≥ 2 mg/L) and anaemia increased for successively higher CKD severity groups; in addition, glycated haemoglobin (HbA1c) ≥ 7% and elevated blood pressure were generally more frequently observed in individuals with CKD than in those without (Table 1). Individuals with ASCVD, CKD stage 3–4 and elevated CRP had higher HbA1c and total cholesterol levels and a greater proportion had obesity, anaemia and elevated blood pressure, compared with individuals with CRP < 2 mg/L (Table 2). Over 5 years’ follow-up, the incidence of 3P-MACE increased with CKD severity (Table 1) and with increasing CRP levels in individuals with ASCVD and CKD stage 3–4 (Table 2). However, only 28% of individuals with ASCVD and CKD stage 3–4 had CRP measurements. Conclusion Adults with ASCVD, CKD and elevated CRP identified from primary and secondary UK care records had a higher disease burden than individuals with CRP levels < 2 mg/L. In the UK, testing CRP levels is not routinely recommended, resulting in a high proportion of missing CRP measurements in this study. Routine testing of CRP may help in identifying patients with residual cardiovascular risk and has the potential to support risk assessment and management of patients with ASCVD and CKD.

Prevalence of Tendon Rupture and Tendinopathies Among Patients with Atherosclerotic Cardiovascular Disease Derived From United States Administrative Claims Data.

The prevalence of tendon rupture and tendinopathies (TRT) has not been determined in a large population of patients with atherosclerotic cardiovascular disease (ASCVD). We investigated TRT prevalence among patients with ASCVD and in the general population, using data from the Symphony Health Integrated Dataverse, a large US medical and pharmacy claims database. This retrospective, observational study included patients aged ≥ 19years from the claims database during the identification period (January 2019 to December 2020) and 12months of continuous enrollment. The primary outcome was evidence of TRT in the 12months following the index date (first ASCVD diagnosis in the ASCVD cohort; first claim in the claims database in the overall population). Diagnostic codes (ICD-10 and/or CPT) were used to define ASCVD and TRT diagnosis. The ASCVD cohort and overall population included 5,589,273 and 61,715,843 patients, respectively. In the ASCVD cohort, use of medications with a potential or known association with TRT was identified in 67.9% (statins), 17.7% (corticosteroids), and 16.7% (fluoroquinolones) of patients. Bempedoic acid use was reported in 1556 (< 0.1%) patients. TRT prevalence during 12-month follow-up was 3.4% (ASCVD cohort) and 1.9% (overall population). Among patients with ASCVD, 83.5% experienced TRT in only one region of the body. Factors most associated with TRT in the ASCVD cohort were increasing age, most notably in those aged 45-‍64 years (odds ratio [OR] 2.19; 95% confidence interval [CI] 2.07-2.32), obesity (OR 1.51; 95% CI 1.50-1.53), and rheumatoid arthritis (OR 1.47; 95% CI 1.45-1.79). Use of statins or bempedoic acid was not associated with increased TRT risk. Patients with ASCVD may have greater risk of TRT than the general population, which may be driven by an increased prevalence of comorbidities and use of medications with a potential or known association with TRT.

Au/FeNiPO4‐Based Multiple Spectra Optoacoustic Tomography/CT Dual‐Mode Nanoprobe for Systemic Screening of Atherosclerotic Vulnerable Plaque

AbstractCurrent diagnostic technique in direct identification of multi‐site plaques and simultaneous assessment of plaque vulnerability remains a challenge, which is crucial for indicating the risk of atherosclerotic cardiovascular diseases (ASCVD). Herein, an osteopontin (OPN)‐specific nanoprobe (OPN Ab‐Au/FeNiPO4@ICG) with both multiple spectra optoacoustic tomography (MSOT) and computed tomography (CT) imaging, is constructed successfully realizing systemic screening of vulnerable plaque. OPN Ab‐Au/FeNiPO4@ICG nanoprobe specifically targeted OPN‐overexpressed foam cells and recognized the vulnerable plaque at the molecular level. In AS mice, CT imaging exhibits that OPN Ab‐Au/FeNiPO4@ICG nanoprobe effectively avoid interference from calcification and accurately visualized AS plaque. MSOT functional imaging results reveals that after the injection of OPN Ab‐Au/FeNiPO4@ICG nanoprobe, the carotid plaque exhibited a much higher MSOT signal than the aortic arch plaque (P = 0.0291). Further pathological analysis displays that the carotid plaque possessed a much higher vulnerability score (P = 0.0247), in agreement with the MSOT signals. More importantly, the linear regression analysis confirms the high correlation between the MSOT signals and plaque vulnerability with R = 0.7095 (P = 0.0216), demonstrating the potential of the proposed nanoprobe in systematic evaluation of plaque vulnerability. This work employs the dual‐model nanoprobe strategy for both plaque localization and vulnerability assessment, greatly advancing the accurate diagnosis of ASCVD.

Multimorbidity in Atherosclerotic Cardiovascular Disease and Its Associations With Adverse Cardiovascular Events and Healthcare Costs: A Real-World Evidence Study

Background: Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of mortality and disability in the United States and worldwide. Objective: To assess the multimorbidity burden and its associations with adverse cardiovascular events (ACE) and healthcare costs among patients with ASCVD. Methods: This is a retrospective observational cohort study using Aetna claims database. Patients with ASCVD were identified during the study period (1/1/2018–10/31/2021). The earliest ASCVD diagnosis date was identified as the index date. Qualified patients were ≥18 years of age and had ≥12 months of health plan enrollment before and after the index date. Comorbid conditions were assessed using all data available within 12 months prior to and including the index date. Association rule mining was applied to identify comorbid condition combinations. ACEs and healthcare costs were assessed using all data within 12 months after the index date. Multivariable generalized linear models were performed to examine the associations between multimorbidity and ACEs and healthcare costs. Results: Of 223 923 patients with ASCVD (mean [SD] age, 73.6 [10.7] years; 42.2% female), 98.5% had ≥2, and 80.2% had ≥5 comorbid conditions. The most common comorbid condition dyad was hypertension-hyperlipidemia (78.7%). The most common triad was hypertension–hyperlipidemia–pain disorders (61.1%). The most common quartet was hypertension–hyperlipidemia–pain disorders–diabetes (30.2%). The most common quintet was hypertension–hyperlipidemia–pain disorders–diabetes–obesity (16%). The most common sextet was hypertension–hyperlipidemia–pain disorders–diabetes–obesity–osteoarthritis (7.6%). The mean [SD] number of comorbid conditions was 7.1 [3.2]. The multimorbidity burden tended to increase in older age groups and was comparatively higher in females and in those with higher social vulnerability. The increased number of comorbid conditions was significantly associated with increased ACEs and increased healthcare costs. Discussion: Extremely prevalent multimorbidity should be considered in the context of clinical decision-making to optimize secondary prevention of ASCVD. Conclusions: Multimorbidity was extremely prevalent among patients with ASCVD. Multimorbidity patterns varied considerably across ASCVD patients and by age, gender, and social vulnerability status. Multimorbidity was strongly associated with ACEs and healthcare costs.

Patterns and gaps in guideline-directed statin use for atherosclerotic cardiovascular disease by race and ethnicity

ObjectiveThere remain disparities by race and ethnicity in atherosclerotic cardiovascular disease (ASCVD). Statins reduce low-density lipoprotein cholesterol (LDL-c) and improve ASCVD outcomes. ASCVD treatment patterns across disaggregated race and ethnicity groups are incompletely understood. We aimed to evaluate statin use and LDL-c control for ASCVD by race and ethnicity. MethodsFrom an electronic health record (EHR)-based cohort from a multisite Northern California health system, we included adults with an ASCVD diagnosis from 2010 to 2021 and at least 2 primary care visits, stratified by race and ethnicity (Non-Hispanic White [NHW], Non-Hispanic Black [Black], Hispanic, and Asian). Hispanic (Mexican, Puerto Rican, Other) and Asian (Asian Indian, Chinese, Filipino, Japanese, Korean, Vietnamese, Other) groups were disaggregated. Primary outcomes were 1-year post-ASCVD statin use (prescription) and LDL-c control (at least one value <70 mg/dL). Adjusted odds ratios (ORs) were estimated using logistic regression. ResultsOf 133,158 patients, there were 89,944 NHW, 6,294 Black, 12,478 (9.4 %) Hispanic and 13,179 (9.9 %) Asian patients. At 1 year after incident ASCVD, there was suboptimal statin use (any statins <60 %, high-intensity <25 %) and LDL-c control (<30 %) across groups, with lowest proportions in Black patients for statin use (46.7 %, any statin) and LDL-c control (10.7 %, OR 0.89 (0.81–0.97), referent NHW). Disaggregation of Asian and Hispanic groups unmasked within-group heterogeneity. ConclusionsIn patients with incident ASCVD, we describe suboptimal and heterogenous 1-year post-ASCVD guideline-directed statin use and 1-year post-ASCVD LDL-c control across disaggregated race and ethnicity groups. Findings may improve understanding of ASCVD treatment disparities and guide implementation.

Effect of Qualifying Atherosclerotic Cardiovascular Disease Diagnosis Proximity on Cardiovascular Risk and Benefit of Empagliflozin in the EMPA-REG OUTCOME Trial

BackgroundIn patients with type 2 diabetes mellitus (T2DM), a history of an ischemic event is associated with increased risk for cardiovascular (CV) disease. Whether patients with T2DM and a recent atherothrombotic diagnosis benefit from early intervention with a sodium-glucose co-transporter 2 inhibitor is unknown. MethodsThis study is a secondary analysis of the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients–Removing Excess Glucose (EMPA-REG OUTCOME), which compared empagliflozin to placebo in adults with T2DM and atherosclerotic CV disease (ASCVD). Participants were categorized based on the time since their last qualifying ASCVD diagnosis (≤ 1 year vs > 1 year). Qualifying ASCVD diagnoses included ischemic or hemorrhagic stroke, myocardial infarction, coronary artery disease, and peripheral artery disease. The primary outcome was a composite of CV death, nonfatal myocardial infarction, or nonfatal stroke. ResultsA total of 6796 participants (n = 4547 empagliflozin, n = 2249 placebo) were included. Median time since the last qualifying ASCVD diagnosis was 3.8 years (quartile 1-quartile 3: 1.5-7.6), and most qualifying diagnoses occurred > 1 year before randomization (≤ 1 year, n = 1214; > 1 year, n = 5582). Empagliflozin reduced the incidence of the primary outcome irrespective of the time since the last qualifying ASCVD diagnosis (≤ 1 year: hazard ratio 0.82, 95% confidence interval: 0.57-1.16; vs > 1 year: hazard ratio 0.85, 95% confidence interval: 0.72-1.00; P for interaction = 0.84). Results were similar for the composite of CV death or hospitalization for heart failure. ConclusionsEmpagliflozin improved CV outcomes in participants with T2DM, irrespective of the time since the last qualifying ASCVD diagnosis at randomization. Prospective trials are necessary to investigate the use of sodium-glucose co-transporter 2 inhibitors at the time of an acute ASCVD event.

Risk estimation for recurrent cardiovascular events using the SMART-REACH model and direct inpatient cost profiling in Indonesian ASCVD patients: a large-scale multicenter study.

With atherosclerotic cardiovascular disease (ASCVD) cases increasing in Indonesia, there is a growing need to identify high-risk patients for recurrent cardiovascular events. Risk stratification could guide optimal secondary preventive therapy. Understanding the ASCVD direct inpatient costs could further provide insight in reducing the economic burden that comes with Indonesia's high number ASCVD cases. However, there is a significant gap in Indonesian large-scale research on both of these valuable data. Employing the SMART-REACH model, we can profile the risk of recurrent cardiovascular events in Indonesian ASCVD patients. Utilize the SMART-REACH model to estimate 10-year and lifetime risk of cardiovascular events in Indonesian ASCVD patients and describe the direct inpatient cost of ASCVD. This descriptive cross-sectional study gathered data from 3,209 ASCVD patients aged 45-80 from two major cardiovascular centers using purposive sampling. Participants were patients admitted between January 2020 and March 2023 with ST-elevated myocardial infarct (STEMI), non-ST-elevated myocardial infarct (NSTEMI), and chronic coronary syndrome (CCS) requiring elective percutaneous coronary intervention (PCI). The SMART-REACH risk estimation model required clinical data upon admission, laboratory results within the first 24 h of admission, and cardiovascular medication prescribed upon discharge. The SMART-REACH model is a Fine and Gray competing risk model incorporating cardiovascular risk factors that estimates individual 10-year and lifetime risk for recurrent cardiovascular events which includes myocardial infarction, stroke, or vascular death. Direct inpatient cost profiling totaled all medical expenses incurred from ASCVD diagnosis admission to discharge. Results were reported descriptively with subgroup analyses. The cohorts (mean age 60.15 ± 8.6 years) were predominantly male [n = 2,537 (79.1%)], hypertensive [n = 2,267 (70.6%)], and diagnosed with STEMI [n = 1,732 (54%)]. The SMART-REACH model calculated a mean 10-year risk of 30.2% (95% CI 29.7-30.6) and a lifetime risk of 62.5% (95% CI 62.1-62.9). The direct inpatient cost of ASCVD patients includes a median 3,033 USD, with highest median costs in the STEMI subgroup (3,270 USD). A significant number of Indonesian ASCVD patients exhibited notably high 10-year and lifetime risks of experiencing a major cardiovascular event. Combined with the direct inpatient cost, therapy optimization is crucially needed to mitigate these risks and further cost burden.

Elevated lipoprotein(a) increases risk of subsequent major adverse cardiovascular events (MACE) and coronary revascularisation in incident ASCVD patients: A cohort study from the UK Biobank

Background and aimsElevated lipoprotein(a) [Lp(a)] is a genetic driver for atherosclerotic cardiovascular disease (ASCVD). We aimed to provide novel insights into the associated risk of elevated versus normal Lp(a) levels on major adverse cardiovascular events (MACE) in an incident ASCVD cohort. MethodsThis was an observational cohort study of incident ASCVD patients. MACE counts and incidence rates (IRs) per 100-person-years were reported for patients with normal (<65 nmol/L) and elevated (>150 nmol/L) Lp(a) within the first year after incident ASCVD diagnosis and overall follow-up. Cox proportional hazard models quantified the risk of MACE associated with a 100 nmol/L increase in Lp(a). ResultsThe study cohort included 32,537 incident ASCVD patients; 5204 with elevated and 22,257 with normal Lp(a). Of those with elevated Lp(a), 41.2% had a subsequent MACE, versus 35.61% with normal Lp(a). Within the first year of follow-up, the IRs of composite MACE and coronary revascularisation were significantly higher (p < 0.001) in patients with elevated versus normal Lp(a) (IR difference 6.79 and 4.66). This trend was also observed in the overall follow-up (median 4.7 years). Using time to first subsequent MACE, a 100 nmol/L increase in Lp(a) was associated with an 8.0% increased risk of composite MACE, and 18.6% increased risk of coronary revascularisation during the overall follow-up period. ConclusionsThe association of elevated Lp(a) with increased risk of subsequent MACE and coronary revascularisation highlights a population who may benefit from earlier and more targeted intervention for cardiovascular risk including Lp(a), particularly within the first year after ASCVD diagnosis. Proactive Lp(a) testing as part of routine clinical practice can help identify and better manage these higher-risk individuals.

Clinical characteristics and treatment patterns in patients with atherosclerotic cardiovascular disease with hypercholesterolemia: a retrospective analysis of a large US real-world database cohort

Objective Guidelines developed by the American College of Cardiology/American Heart Association (ACC/AHA) recommend lipid-lowering therapies (LLTs) to reduce low-density lipoprotein cholesterol (LDL-C) and atherosclerotic cardiovascular disease (ASCVD) risk. This study described LLT utilization patterns and LDL-C goal achievement (to <70 mg/dL) among patients with ASCVD in the United States. Methods This retrospective study was conducted using Optum’s de-identified Clinformatics Data Mart Database (CDM). Patients with their first ASCVD diagnosis (index date) in the CDM database between July 1, 2015, and December 31, 2018, were followed for ≥12 months to assess LLT utilization patterns and change in LDL-C. LLTs included were statins and non-statin LLTs (ezetimibe, fibrates, and proprotein convertase subtilisin/kexin type 9 inhibitors). Adherence was measured as the proportion of days covered (PDC), defined as the number of days with drug on-hand (or number of days exposed to drug) divided by the 12-month follow-up period. Patients with PDC ≥0.8 were considered adherent. Results Among the patients with ASCVD (N = 1,424,893) included in this study, only 621,978 (43.7%) had at least one LDL-C measurement at baseline (6 months prior to and 3 months after the index date). The mean age was 71.5 years, and almost half of the patients were female. Patients were followed for a mean (standard deviation [SD]) duration of 30.6 (11.4) months (median of 29.9 months). During the follow-up, about one-quarter of the patients did not receive any LLT. Among treated patients, 89.5% received statins and 10.5% received non-statin LLT. Less than half (47.6%) of the patients were adherent to the index treatment during the 12-month follow-up. Even in patients receiving combination therapy (statin + non-statin LLT), a sizable proportion (35.8%) showed an increase in LDL-C over the follow-up period. Conclusions This retrospective study highlighted limited LDL-C monitoring in patients with ASCVD, and unmet need in terms of suboptimal utilization of non-stain LLTs, limited adherence to LLTs, and inadequate lipid control after treatment (among those with LDL-C measurements during the follow-up period) need to be addressed to improve outcomes in this patient cohort.

Lipid assessment and achievement of secondary prevention european society of cardiology guideline targets in patients with atherosclerotic cardiovascular disease with and without depression

Abstract Background Patients who have a diagnosis of atherosclerotic cardiovascular disease (aCVD) who also have depression (Dep) have a worse CV prognosis than those without Dep. Appropriate secondary prevention greatly improves CVD outcomes. The European Society of Cardiology (ESC) provide guideline targets for lipid levels (2016 &amp; 2019). It is unknown how well these targets are achieved and maintained over time in patients with aCVD at a population level and whether this differs in those with and without Dep. Purpose To investigate the assessment of lipid levels and/or achievement of guideline targets in patients with aCVD with and without Dep over an 11-year period. Methods A retrospective observational cohort study of patients with aCVD was conducted on individual-level linked electronic health record data between 2009 &amp;2019 using the all-Wales SAIL databank. Clinical codes were used to identify aCVD and Dep diagnoses, lipid assessments and lipid-lowering therapy (LLT) from GP data. The proportions of those having lipid assessments during each calendar year, lipid levels achieving ESC 2016 guideline targets and current LLT were documented. Results In 2009, the aCVD cohort comprised of 183,275 patients (44% female) with a mean age (70.6 ±12.3 years), of whom 22% had a Dep diagnosis (56.6% female). In 2009, lipid levels were assessed in 63.1% of patients, dropping to 48.3% by 2019 (68.06% Dep, 61.65% non-Dep in 2009 and 51.7% Dep, 46.84% non-Dep in 2019. Table and Figure). Over the period of study an increasing proportion of patients were prescribed High intensity statins (HIS) and a decreasing proportion were prescribed low intensity statin (LIS) and/or Ezetimibe. Dep patients were more likely to be treated with HIS and/or Ezetimibe and less likely to receive LIS throughout compared with non-Dep (table). An increasing trend for lipid targets being achieved was observed between 2009 and 2019 in those being tested (Table and Figure). However, a significantly smaller proportion of those with Dep met the ESC targets vs non-Dep over the period of study (Table and Figure). Conclusion The proportion of aCVD patients having their lipids checked fell progressively between 2009 and 2019, although a greater proportion of those "checked" patients had achieved LDL-C and non-HDL-C targets, although the proportion who met these targets remained low. Despite patients with aCVD and Dep being more likely to have their lipids assessed and to be prescribed more intensive LLT those without Dep, with the "gap" widening over time. Considerable additional effort will be required in the future to meet the more intensive 2019 targets in these very high risk patients.

Abstract 16164: Lipoprotein (a) Testing in Patients With Atherosclerotic Cardiovascular Disease in Five Large U.S. Health Systems

Introduction: Lipoprotein (a) [Lp(a)] is an independent, causal risk factor for atherosclerotic cardiovascular disease (ASCVD). Screening patterns remain variable and it is unclear what factors are associated with Lp(a) testing, and whether knowing the Lp(a) value changes management. Research Question: To better understand the proportion of Lp(a) testing, factors predicting Lp(a) testing, and impact on management in ASCVD patients. Methods: A retrospective study using electronic medical record data from five health systems in the CardioHealth Alliance and PCORnet® identified a cohort with an ASCVD diagnosis in 5 years prior to the index date. The index date was defined as the date of the first Lp(a) test result in 2019-2021 for those with a Lp(a) test, or the date of a randomly selected outpatient encounter in 2019-2021 for those without a Lp(a) test. Initiation of lipid lowering therapy (LLT) was assessed within 6 months after the index date. Multivariable regression modeling was used to determine factors associated with Lp(a) testing. Results: Among 595,685 ASCVD participants, only 2,588 (0.4%) were tested for Lp(a). In adjusted models, those who were older, Black, or Hispanic were less likely to have Lp(a) testing, while those with familial hypercholesterolemia, ischemic stroke/TIA, PAD, prior LLT, or LDL-C ≥130mg/dL were more likely to be tested (table). Those with elevated Lp(a) (&gt;50mg/dL or &gt;125 nmol/L) were more likely to initiate any LLT (43.9% vs 34.6%, p=0.03), particularly PCSK9i (10.9% vs 4.8%, p&lt;0.01) and ezetimibe (11.5% vs 5.9%, p &lt;0.01) compared to those without elevated Lp(a). Statin initiation remained similar between those with and without elevated Lp(a) (32.1% vs 29.5%, p=0.47). Conclusion: Lp(a) testing in ASCVD patients is infrequent, with evidence of disparities by race and ethnicity. Having elevated Lp(a) was associated with higher initiation of non-statin LLT. However, overall initiation of any LLT after an elevated Lp(a) test was low.

FRI085 Lipid Lowering Therapy Deficits In Secondary Cardiovascular Prevention In A Large Cohort From Eight Busy Clinics In Greece Over 12 Years

Abstract Disclosure: R.D. Paparodis: None. I. Androulakis: None. D.P. Askitis: None. I. Perogamvros: None. N. Angelopoulos: None. A. Rizoulis: None. S. Livadas: None. A. Boniakos: None. Background: The increasing availability of aggressive lipid lowering therapies (LLTs) worldwide is expected to produce a significant decline in cholesterol concentrations worldwide and a more successful attainment of LDL lowering goals (LLGs), especially in those who need them most: patients with established atherosclerotic cardiovascular disease (ASCVD). Aims: To assess the long-term changes in the rate of attainment of LGs according to the European Society of Cardiology Guidelines nationwide, with the use of different LLTs during 12 consecutive years. Methods: We reviewed the charts of all patients initially seen between 2010-2022 who returned for care follow up at our 8 busy Endocrinology clinics, located in 6 cities in Greece, between Sep-1-2022 and Nov-30-2022. We enrolled those with recorded diagnosis of ASCVD [coronary artery disease (CAD), peripheral arterial disease (PAD) or carotid stenosis &amp;gt;50% (CS)] prior to our initial visit. For the present work, we reviewed data on tobacco use, intake of LLTs, and LDL-cholesterol concentrations as recorded during our initial clinic visit. We excluded all patients referred to our clinics for lipids management. Data are presented as means ± standard deviation. Means are compared with Kruskal Wallis test and p&amp;lt;0.05 is deemed significant. Results: We enrolled n=890 consecutive patients, age 63.9 ± 11.4 years, n=339 were women (38.1%), n=529 (59.4%) had diabetes, n=672 (75.5%) had hypertensions and all had ≥1 forms of established ASCVD: n=630 with CAD, n=279 with CS and n=151 with PAD. Out of these, n=144 (16.2%) were on no LLTs, n=334 (37.5%) continued to smoke, n=381 (42.8%) were on guidelines-based appropriate LLT strategy, n=248 (27.9%) reached LLGs and n=318 (35.7%) fulfilled the year-specific guidelines requirements. Of note is, that this rate dropped to 2.4-20.4% in the years 2019-2022. The likelihood of achieving LDL goals was not statistically significantly different among patients with different forms of ASCVD (p=0.42). Overall, the mean LDL was 88.2 ± 32.1mg/dl, and was not different between patients with different forms of ASCVD (p=0.75). Mean LDL concentrations have only started to drop between 2020-2022 as compared to 2019 (p&amp;lt;0.001), but are not different compared to those seen in the years 2010-2018. The mean LDL dropped to 82.3 ± 30.5mg/dl in 2022 as compared to 102.2 ± 38.8mg/dl in 2019. Conclusions: Our study reveals a large care gap in patients with established ASCVD, which did not seem to improve significantly over the past 12 years, despite the excellent availability of aggressive LLT strategies in Greece. Intervention studies are urgently needed to enhance adherence to updated international guidelines and reduce the extremely high ASCVD risk in this fragile population.
