Impact of statin adherence and interruption within 6 months after ST-segment elevation myocardial infarction (STEMI): Results from the real-world regional registry FAST-STEMI. Int J Cardiol 2024; 405:131933. [PMID: 38437950 DOI: 10.1016/j.ijcard.2024.131933] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 02/15/2024] [Accepted: 03/01/2024] [Indexed: 03/06/2024]
Abstract
BACKGROUND The impact of statin therapy on cardiovascular outcomes after ST-elevation acute myocardial infarction (STEMI) in real- world patients is understudied. AIMS To identify predictors of low adherence and discontinuation to statin therapy within 6 months after STEMI and to estimate their impact on cardiovascular outcomes at one year follow-up. METHODS We evaluated real-world adherence to statin therapy by comparing the number of bought tablets to the expected ones at 1 year follow-up through pharmacy registries. A total of 6043 STEMI patients admitted from 2012 to 2017 were enrolled in the FAST STEMI registry and followed up for 4,7 ± 1,6 years; 304 patients with intraprocedural and intrahospital deaths were excluded. The main outcomes evaluated were all-cause death, cardiovascular death, myocardial infarction, major and minor bleeding events, and ischemic stroke. The compliance cut-off chosen was 80% as mainly reported in literature. RESULTS From a total of 5744 patients, 418 (7,2%) patients interrupted statin therapy within 6 months after STEMI, whereas 3337 (58,1%) presented >80% adherence to statin therapy. Statin optimal adherence (>80%) resulted as protective factor towards both cardiovascular (0.1% vs 4.6%; AdjHR 0.025, 95%CI 0.008-0.079, p < 0.001) and all-cause mortality (0.3% vs 13.4%; Adj HR 0.032, 95%CI 0.018-0.059, p < 0.001) at 1 year follow-up. Further, a significant reduction of ischemic stroke incidence (1% vs 2.5%, p = 0.001) was seen in the optimal adherent group. Statin discontinuation within 6 months after STEMI showed an increase of both cardiovascular (5% vs 1.7%; AdjHR 2.23; 95%CI 1.37-3.65; p = 0,001) and all-cause mortality (14.8% vs 5.1%, AdjHR 2.32; 95%CI 1.73-3.11; p 〈0,001) at 1 year follow-up. After multivariate analysis age over 75 years old, known ischemic cardiopathy and female gender resulted as predictors of therapy discontinuation. Age over 75 years old, chronic kidney disease, previous atrial fibrillation, vasculopathy, known ischemic cardiopathy were found to be predictors of low statin adherence. CONCLUSIONS n our real-world registry low statin adherence and discontinuation therapy within 6 months after STEMI were independently associated to an increase of cardiovascular and all-cause mortality at 1 year follow-up. Low statin adherence led to higher rates of ischemic stroke.

Intensity of and adherence to lipid-lowering therapy as predictors of goal attainment and major adverse cardiovascular events in primary prevention. Am Heart J 2024; 269:118-130. [PMID: 38109988 DOI: 10.1016/j.ahj.2023.12.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 11/25/2023] [Accepted: 12/10/2023] [Indexed: 12/20/2023]
Abstract
BACKGROUND The effectiveness of lipid-lowering therapy (LLT) for primary prevention of atherosclerotic cardiovascular disease (ASCVD) in routine care may depend on treatment intensity and adherence. METHODS Observational study of adults with newly initiated LLT for primary prevention of ASCVD in Stockholm, Sweden, during 2017-2021. Study exposures were LLT adherence [proportion of days covered (PDC)], LLT intensity (expected reduction of LDL cholesterol), and the combined measure of adherence and intensity. At each LLT fill, adherence and intensity were calculated during the previous 12 months, and the patients estimated ASCVD risk was categorized. Study outcomes were major adverse cardiovascular events (MACE) and LDL-C goal attainment. RESULTS Thirty-six thousand two hundred eighty-three individuals (mean age 63 years, 47% women, median follow-up 2 years), with a baseline low-moderate (40%), high (49%), and very-high (11%) ASCVD risk started LLT. Increases in LLT adherence, intensity, or adherence-adjusted intensity of 10% over 1 year were associated with lower risks of MACE (with hazard ratios of 0.95 [95% CI, 0.93-0.98]; 0.93 [0.86-1.00]; and 0.90 [0.85-0.95], respectively) and higher odds of attaining LDL goals. Patients with good adherence (≥80%) had similar risks of MACE and similar odds ratios for LDL-C goal attainment with low-moderate and high-intensity LLT. Treatment discontinuation was associated with increased MACE risk. The relative and absolute benefits of good adherence were greatest in patients with very high ASCVD risk. CONCLUSION In routine-care primary prevention, better adherence to LLT was associated with a lower risk of MACE across all treatment intensities. Improving adherence is especially important among patients with very high ASCVD risk.

Investigation of the Therapeutic Potential of Organic Nitrates in Mortality Reduction Following Acute Myocardial Infarction in Hyperlipidemia Patients: A Population-Based Cohort Study. J Pers Med 2024; 14:124. [PMID: 38276246 PMCID: PMC10820449 DOI: 10.3390/jpm14010124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 01/10/2024] [Accepted: 01/17/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND Dyslipidemia is a known risk factor for cardiac dysfunction, and lipid-lowering therapy with statins reduces symptoms and reduces hospitalization related to left ventricular heart failure. Acute myocardial infarction (AMI) is a cause of morbidity and mortality worldwide. In this study, we aimed to determine the real-world AMI treatment drug combination used in Taiwan by using the NHI database to understand the treatment outcomes of current clinical medications prescribed for hyperlipidemia patients with AMI. METHODS Using the NHI Research Database (NHIRD), we conducted a retrospective cohort study that compared different treatments for AMI in hyperlipidemia patients in the period from 2016 to 2018. We compared the survival outcomes between those treated with and without organic nitrates in this cohort. RESULTS We determined that most hyperlipidemia patients were aged 61-70 y (29.95-31.46% from 2016 to 2018), and the annual AMI risk in these patients was <1% (0.42-0.68% from 2016 to 2018). The majority of hyperlipidemia patients with AMI were women, and 25.64% were aged 61-70 y. Receiving organic nitrates was associated with lower all-cause mortality rates (HR, 95% CI, p-value = 0.714, 0.674-0.756, p < 0.0001). After multivariate analysis, the overall survival in four groups (beta-blockers, beta-blocker + diuretics, diuretics, and others) receiving an organic nitrate treatment was significantly higher than in the groups that were not treated with organic nitrates (beta-blockers HR = 0.536, beta-blocker + diuretics HR = 0.620, diuretics HR = 0.715, and others HR = 0.690). CONCLUSIONS The survival benefit was significantly greater in patients treated with organic nitrates than in those treated without organic nitrates, especially when combined with diuretics. A combination of organic nitrates could be a better treatment option for hyperlipidemia patients with AMI.

Clin Cardiol 2022; 45:1220-1228. [PMID: 36116032 DOI: 10.1002/clc.23898] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 07/20/2022] [Accepted: 07/26/2022] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Cardiovascular medications are vital for the secondary prevention of coronary arterial disease (CAD). However, the effect of cardiovascular medication may depend on the optimal adherence of the patients. This meta-analysis aims to determine the magnitude of adherence to vascular medications that influences the absolute and relative risks (RRs) of mortality in patients with CAD in real-world settings. METHODS The Cochrane Library, PubMed, and EMBASE databases were searched through March 1, 2022. Prospective studies reporting association as RR and 95% confidence interval between cardiovascular medication adherence and any cardiovascular events and/or all-cause mortality in patients with CAD were included. A one-stage robust error meta-regression method was used to summarize the dose-specific relationships. RESULTS A total of 18 studies were included. There is a significant inverse linear association between cardiovascular medication adherence and cardiovascular events (pnonlinearity = .68) or mortality (pnonlinearity = .82). The exposure-effect analysis showed that an improvement of 20% cardiovascular medication adherence was associated with 8% or 12% lower risk of any cardiovascular events or mortality, respectively. In subgroup analysis, the benefit was observed in adherence of stain (RR: 0.90, for cardiovascular events, RR: 0.85, for mortality), angiotensin-converting enzyme inhibitors (ACEI)/angiotensin II receptor blockers (ARB)(RR: 0.90, for mortality), and antiplatelet agent (RR: 0.89 for mortality) but not in beta-blocker (RR: 0.90, p = .14, for cardiovascular events, RR: 0.97, p = .32 for mortality). Estimated absolute differences per 1 million individuals per year for mortality associated with 20% improvement were 175 cases for statin, 129 cases for antiplatelet, and 117 cases for ACEI/ARB. CONCLUSION Evidence from the real word showed poor adherence to vascular medications contributes to a considerable proportion of all cardiovascular disease events and mortality in patients with CAD.

Generating Practice-Based Evidence in the Use of Guideline-Recommended Combination Therapy for Secondary Prevention of Acute Myocardial Infarction. PHARMACY 2022; 10:pharmacy10060147. [PMID: 36412823 PMCID: PMC9680510 DOI: 10.3390/pharmacy10060147] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 10/28/2022] [Accepted: 10/29/2022] [Indexed: 11/06/2022] Open
Abstract
Background: Clinical guidelines recommend beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers, and statins for the secondary prevention of acute myocardial infarction (AMI). It is not clear whether variation in real-world practice reflects poor quality-of-care or a balance of outcome tradeoffs across patients. Methods: The study cohort included Medicare fee-for-service beneficiaries hospitalized 2007-2008 for AMI. Treatment within 30-days post-discharge was grouped into one of eight possible combinations for the three drug classes. Outcomes included one-year overall survival, one-year cardiovascular-event-free survival, and 90-day adverse events. Treatment effects were estimated using an Instrumental Variables (IV) approach with instruments based on measures of local-area practice style. Pre-specified data elements were abstracted from hospital medical records for a stratified, random sample to create "unmeasured confounders" (per claims data) and assess model assumptions. Results: Each drug combination was observed in the final sample (N = 124,695), with 35.7% having all three, and 13.5% having none. Higher rates of guideline-recommended treatment were associated with both better survival and more adverse events. Unmeasured confounders were not associated with instrumental variable values. Conclusions: The results from this study suggest that providers consider both treatment benefits and harms in patients with AMIs. The investigation of estimator assumptions support the validity of the estimates.

Abstract
Background The effectiveness of lipid-lowering therapy (LLT) is affected by both intensity and adherence. This study evaluated the associations of LLT intensity, adherence, and the combination of these 2 aspects of LLT management with the risk of major adverse cardiovascular events (MACE) in people with coronary heart disease. Methods and Results This is an observational study of all adults who suffered a myocardial infarction or had coronary revascularization during 2012 to 2018 and initiated LLT in Stockholm, Sweden. Study exposures were LLT adherence (proportion of days covered), LLT intensity (expected reduction of low-density lipoprotein cholesterol), and the combined measure of adherence and intensity. At each LLT fill, adherence and intensity during the previous 12 months were calculated. The primary outcomes were MACE (nonfatal myocardial infarction or stroke and death); secondary outcomes were low-density lipoprotein cholesterol goal attainment and individual components of MACE. We studied 20 490 patients aged 68±11 years, 75% men, mean follow-up 2.6±1.1 years. Every 10% increase in 1-year adherence, intensity, or adherence-adjusted intensity was associated with a lower risk of MACE (hazard ratio [HR], 0.94 [95% CI, 0.93-0.96]; HR, 0.92 [95% CI, 0.88-0.96]; and HR, 0.91 [95% CI, 0.89-0.94], respectively) and higher odds of attaining low-density lipoprotein cholesterol goals (odds ratio [OR],1.12 [95% CI, 1.10-1.15]; OR, 1.42 [95% CI, 1.34-1.51], and OR, 1.16 [95% CI, 1.19-1.24], respectively). Among patients with good adherence (≥80%), the risk of MACE was similar with low-moderate and high-intensity LLT despite differences in the low-density lipoprotein cholesterol goal attainment with the treatment intensities. Discontinuation ≥1 year increased the risk markedly (HR,1.66 [95% CI, 1.23-2.22]). Conclusions In routine care, good adherence to LLT was associated with the greatest benefit for patients with coronary heart disease. Strategies that improve adherence and use of intensive therapies could substantially reduce cardiovascular risk.

Abstract
OBJECTIVES To determine if comparable older women and men received different durations of P2Y12 inhibitor therapy following acute myocardial infarction (AMI) and if therapy duration differences were justified by differences in ischaemic benefits and/or bleeding risks. DESIGN Retrospective cohort. SETTING 20% sample of 2007-2015 US Medicare fee-for-service administrative claims data. PARTICIPANTS ≥66-year-old P2Y12 inhibitor new users following 2008-2013 AMI hospitalisation (N=30 613). Older women compared to older men with similar predicted risks of study outcomes. PRIMARY AND SECONDARY OUTCOME MEASURES Primary outcome: P2Y12 inhibitor duration (modelled as risk of therapy discontinuation). SECONDARY OUTCOMES clinical events while on P2Y12 inhibitor therapy, including (1) death/hospice admission, (2) composite of ischaemic events (AMI/stroke/revascularisation) and (3) hospitalised bleeds. Cause-specific risks and relative risks (RRs) estimated using Aalen-Johansen cumulative incidence curves and bootstrapped 95% CIs. RESULTS 10 486 women matched to 10 486 men with comparable predicted risks of all 4 study outcomes. No difference in treatment discontinuation was observed at 12 months (women 31.2% risk; men 30.9% risk; RR 1.01; 95% CI 0.97 to 1.05), but women were more likely than men to discontinue therapy at 24 months (54.4% and 52.9% risk, respectively; RR 1.03; 95% CI 1.00 to 1.05). Among patients who did not discontinue P2Y12 inhibitor therapy, women had lower 24-month risks of ischaemic outcomes than men (13.1% and 14.7%, respectively; RR 0.90; 95% CI 0.84 to 0.96), potentially lower 24-month risks of death/hospice admission (5.0% and 5.5%, respectively; RR 0.91; 95% CI 0.82 to 1.02), but women and men both had 2.5% 24-month bleeding risks (RR 0.98; 95% CI 0.82 to 1.14). CONCLUSIONS Risks for death/hospice and ischaemic events were lower among women still taking a P2Y12 inhibitor than comparable men, with no difference in bleeding risks. Shorter P2Y12 inhibitor durations in older women than comparable men observed between 12 and 24 months post-AMI may reflect a disparity that is not justified by differences in clinical need.

Abstract
Several studies have shown that non-adherence to medication use is associated with lower use of preventive services and increased mortality. We aimed to study the relationship between initial adherence to medication use and mortality in the Prostate Cancer Prevention Trial (PCPT). The PCPT randomized men age 55 and over to a finasteride or placebo arm. Duration of treatment was seven years, followed by end-of-study prostate biopsy. Extended follow-up for mortality was performed by linkage to the National Death Index. Non-adherence was defined as taking under 80% of required pills during the first or second 6-month trial period. Proportional hazards models were used to assess the relationship between adherence and all-cause mortality (excluding prostate cancer deaths). Three models were developed as follows: Model I (controlling for demographics and trial arm), Model II (Model I factors plus specific medical conditions), Model III (Model II factors plus lifestyle factors). Of 18,667 men included in the analysis, 3082 (16.5%) were non-adherent. The most common reasons for non-adherence were side effects (33.9%) and forgetting to take pills (22%). Through 5 and 10 years of follow-up, 178 (5.9%) and 483 (15.7%) non-adherent men died versus 581 (3.7%) and 1887 (12.1%) adherent men. Hazard ratios (HRs) at 5 years were 1.62 (95% CI: 1.37-1.91), 1.55 (95% CI: 1.30-1.83) and 1.49 (95% CI: 1.25-1.76) for Models I-III. HRs at ten years were lower but still statistically significant. Non-adherence to taking protocol medications was associated with increased mortality from unrelated conditions.

Abstract
BACKGROUND Of 58 medication adherence group-based trajectory modeling (GBTM) published studies, 74% used binary and 26% used continuous GBTM. Few studies provided a rationale for this choice. No medication adherence studies have compared continuous and binary GBTM. OBJECTIVE The objective of this study was to assess whether continuous versus binary GBTM: (1) impacts adherence trajectory shapes; and (2) results in the differential classification of patients into adherence groups. METHODS Patients were prevalent statin users with myocardial infarction hospitalization, 66+ years old, and continuously enrolled in fee-for-service Medicare. Statin medication adherence was measured 6 months prehospitalization using administrative claims. Final GBTM specifications beyond default settings were selected using a previously defined standardized procedure and applied separately to continuous and binary (proportion of days covered ≥0.80) medication adherence measures. Assignment to adherence groups was compared between continuous and binary models using percent agreement of patient classification and the κ coefficient. RESULTS Among 113,296 prevalent statin users, 4 adherence groups were identified in both models. Three groups were consistent: persistently adherent, progressively nonadherent, and persistently nonadherent. The fourth continuous group was moderately adherent (progressively adherent in the binary model). When comparing patient assignment into adherence groups between continuous and binary trajectory models, only 78.4% of patients were categorized into comparable groups (κ=0.641; 95% confidence interval: 0.638-0.645). The agreement was highest in the persistently adherent group (∼94%). CONCLUSIONS Continuous and binary trajectory models are conceptually different measures of medication adherence. The choice between these approaches should be guided by study objectives and the role of medication adherence within the study-exposure, outcome, or confounder.

Real-world Evidence for Adherence and Persistence with Atorvastatin Therapy. Cardiol Ther 2021; 10:445-464. [PMID: 34586613 PMCID: PMC8555050 DOI: 10.1007/s40119-021-00240-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Indexed: 12/17/2022] Open
Abstract
Atorvastatin, which has been approved by regulatory agencies for primary- and secondary-prevention patients with dyslipidemia, has historically been the most commonly prescribed statin and is now widely available in generic formulations. Despite widespread statin usage, many patients fail to attain recommended (LDL-C) targets. While several factors impact the successful treatment of dyslipidemia, suboptimal patient adherence is a major limiting factor to medication effectiveness. In this narrative review we sought to investigate patient adherence and persistence with atorvastatin in a real-world setting and to identify barriers to LDL-C goal attainment and therapy outcomes beyond the realm of clinical trials. Moreover, in light of growing generic usage, we carried out targeted literature searches to investigate the impact of generic atorvastatin availability on patient adherence/persistence, and on lipid and efficacy outcomes, compared with branded formulations. Unsurprisingly, real-world data suggest that patient adherence/persistence to atorvastatin is suboptimal, but few studies have attempted to address factors impacting adherence. Data from studies comparing adherence/persistence in patients prescribed branded or generic atorvastatin are limited and show no clear evidence that initiation of a specific preparation of atorvastatin impacts adherence/persistence. Furthermore, results from studies comparing adherence/persistence of patients who switched from the branded to the generic drug are conflicting, although they do suggest that switching may negatively impact adherence over the long term. Additional real-world studies are clearly required to understand potential differences in adherence and persistence between patients initiating treatment with branded versus generic atorvastatin and, moreover, the factors that influence adherence. Targeted education initiatives and additional research are needed to understand and improve patient adherence in a real-world setting.

Am J Prev Cardiol 2021; 7:100187. [PMID: 34611633 PMCID: PMC8387292 DOI: 10.1016/j.ajpc.2021.100187] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 03/26/2021] [Accepted: 04/16/2021] [Indexed: 11/24/2022] Open
Abstract
OBJECTIVE The 2018 American Heart Association/American College of Cardiology (AHA/ACC) Blood Cholesterol Guideline recommendation to classify patients with atherosclerotic cardiovascular disease (ASCVD) as very high-risk (VHR) vs not-VHR (NVHR) has important implications for escalation of medical therapy. We aimed to define the prevalence and clinical characteristics of these two groups within a large multi-state healthcare system and develop a simpler means to assist clinicians in identifying VHR patients using classification and regression tree (CART) analysis. METHODS We performed a retrospective analysis of all patients in a 28-hospital US healthcare system in 2018. ICD-10 codes were used to define the ASCVD population. Per the AHA/ACC Guideline, VHR status was defined by ≥2 major ASCVD events or 1 major ASCVD event and ≥2 high-risk conditions. CART analysis was performed on training and validation datasets. A random forest model was used to verify results. RESULTS Of 180,669 ASCVD patients identified, 58% were VHR. Among patients with a history of myocardial infarction (MI) or recent acute coronary syndrome (ACS), 99% and 96% were classified as VHR, respectively. Both CART and random forest models identified recent ACS, ischemic stroke, hypertension, peripheral artery disease, history of MI, and age as the most important predictors of VHR status. Using five rules identified by CART analysis, fewer than 50% of risk factors were required to assign VHR status. CONCLUSION CART analysis helped to streamline the identification of VHR patients based on a limited number of rules and risk factors. This approach may help improve clinical decision making by simplifying ASCVD risk assessment at the point of care. Further validation is needed, however, in more diverse populations.

Use of Lipid-Lowering Therapies Over 2 Years in GOULD, a Registry of Patients With Atherosclerotic Cardiovascular Disease in the US. JAMA Cardiol 2021; 6:2780713. [PMID: 34132735 PMCID: PMC8209562 DOI: 10.1001/jamacardio.2021.1810] [Citation(s) in RCA: 81] [Impact Index Per Article: 27.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Accepted: 04/20/2021] [Indexed: 12/14/2022]
Abstract
IMPORTANCE Guidelines for patients with atherosclerotic cardiovascular disease (ASCVD) recommend intensive statin therapy and adding nonstatin therapy if low-density lipoprotein cholesterol (LDL-C) levels are 70 mg/dL or more. Compliance with guidelines is often low. OBJECTIVE To track LDL-C treatment patterns in the US over 2 years. DESIGN, SETTING, AND PARTICIPANTS GOULD is a prospective observational registry study involving multiple centers. Patients with ASCVD receiving any lipid-lowering therapy (LLT) were eligible. Between December 2016 and July 2018, patients were enrolled in 1 of 3 cohorts: (1) those currently receiving proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i) and 2 groups not receiving PCSK9i drugs, with (2) LDL-C levels of 100 mg/dL or more or (3) LDL-C levels of 70 to 99 mg/dL. Patients had medical record reviews and telephone interviews every 6 months. Analysis was done on data collected as of October 5, 2020. MAIN OUTCOMES AND MEASURES The primary outcome was the change in LLT use in 2 years. Secondary outcomes included the number of LDL-C measurements, LDL-C levels, and responses to structured physician and patient questionnaires over 2 years. RESULTS A total of 5006 patients were enrolled (mean [SD] age, 67.8 [9.9] years; 1985 women [39.7%]; 4312 White individuals [86.1%]). At 2 years, 885 (17.1%) had LLT intensification. In the cohorts with LDL-C levels of 100 mg/dL or more and 70 to 99 mg/dL, LLT intensification occurred in 403 (22.4%) and 383 (14.4%), respectively; statins were intensified in 115 (6.4%) and 168 (6.3%), ezetimibe added in 123 (6.8%) and 118 (4.5%), and PCSK9i added in 114 (6.3%) and 58 (2.2%), respectively. In the PCSK9i cohort, 508 of 554 (91.7%) were still taking PCSK9i at 2 years. Lipid panels were measured at least once over 2 years in 3768 patients (88.5%; PCSK9i cohort, 492 [96.1%]; LDL-C levels ≥100 mg/dL or more, 1294 [85.9%]; 70-99 mg/dL, 1982 [88.6%]). Levels of LDL-C fell from medians (interquartile ranges) of 120 (108-141) mg/dL to 95 (73-118) mg/dL in the cohort with LDL-C levels of 100 mg/dL or more, 82 (75-89) to 77 (65-90) mg/dL in the cohort with LDL-C levels of 70 to 99 mg/dL, and 67 (42-104) mg/dL to 67 (42-96) mg/dL in the PCSK9i cohort. Levels of LDL-C less than 70 mg/dL at 2 years were achieved by 308 patients (21.0%) and 758 patients (33.9%) in the cohorts with LDL-C levels of 100 mg/dL or more and 70 to 99 mg/dL, respectively, and 272 patients (52.4%) in the PCSK9i cohort. At 2 years, practice characteristics were associated with more LLT intensification (teaching vs nonteaching hospitals, 148 of 589 [25.1%] vs 600 of 3607 [16.6%]; lipid protocols or none, 359 of 1612 [22.3%] vs 389 of 2584 [15.1%]; cardiology, 452 of 2087 [21.7%] vs internal or family medicine, 204 of 1745 [11.7%] and other, 92 of 364 [25.3%]; all P < .001) and achievement of LDL-C less than 70 mg/dL (teaching vs nonteaching hospitals, 173 of 488 [35.5%] vs 823 of 2986 [27.6%]; lipid protocols vs none, 451 of 1411 [32.0%] vs 545 of 2063 [26.4%]; both P < .001; cardiology, 523 of 1686 [30.1%] vs internal or family medicine, 377 of 1472 [25.6%] and other, 96 of 316 [30.4%]; P = .003). CONCLUSIONS AND RELEVANCE Of patients with ASCVD, most with suboptimal LDL-C levels at baseline, only 17.1% had LLT intensification after 2 years, and two-thirds remained at an LDL-C level greater than 70 mg/dL. Further intensive efforts are needed to achieve optimal LDL-C management in patients with ASCVD.

Abstract
Aims Statin treatment is one of the hallmarks of secondary prevention after myocardial infarction. Adherence to statins tends to be difficult and can be improved by patient education. Novel technologies such as mixed reality (MR) expand the possibilities to support this process. To assess if an MR medication-application supports patient education focused on function of statins after myocardial infarction. Methods and results A human-centred design-approach was used to develop an MR statin tool for Microsoft HoloLens™. Twenty-two myocardial infarction patients were enrolled; 12 tested the application, 10 patients were controls. Clinical, demographic, and qualitative data were obtained. All patients performed a test on statin knowledge. To test if patients with a higher tendency to become involved in virtual environments affected test outcome in the intervention group, validated Presence- and Immersive Tendency Questionnaires (PQ and ITQ) were used. Twenty-two myocardial infarction patients (ST-elevation myocardial infarction, 18/22, 82%) completed the study. Ten out of 12 (83%) patients in the intervention group improved their statin knowledge by using the MR application (median 8 points, IQR 8). Test improvement was mainly the result of increased understanding of statin mechanisms in the body and secondary preventive effects. A high tendency to get involved and focused in virtual environments was moderately positive correlated with better test improvement (r = 0.57, P < 0.05). The median post-test score in the control group was poor (median 6 points, IQR 4). Conclusions An MR statin education application can be applied effectively in myocardial infarction patients to explain statin function and importance.

Abstract
BACKGROUND AND OBJECTIVES There is deficient control of dyslipidaemia after ST-elevation myocardial infarction (STEMI) despite high rates of statin prescription. The aim of this study was to estimate the rate of statin treatment adherence after a first type 1 STEMI episode, the factors that determine the adherence and its impact on cardiovascular outcomes during the first year of progression. DESIGN We conducted an observational retrospective study with a cohort of patients hospitalised between 2008 and 2013, with an active statin prescription during the first year of follow-up. MATERIAL AND METHODS We determined the adherence using the proportion of days covered. The relationship between compliance and the rest of the variables was determined with a binary logistic regression analysis. Competing risk analysis assessed the relationship between cardiovascular mortality or new vascular event with adherence. RESULTS The study included 552 patients (64.7 ± 13.7; 73.9% men) of the 613 analysed. There was less adherence among foreign nationals, smokers and individuals with hepatic impairment. Compliance was greater starting at 50 years of age, among pensioners and those with dyslipidaemia, obesity and kidney failure and in cases of compliance with the rest of the groups indicated in secondary prevention. Compliance reduced cardiovascular mortality (1.9% vs. 9.1%; HR 0.201; 95% CI 0.075-0.539; p = .001) but not the onset of a new cardiovascular event (5.5% vs. 6.5%; p = .834). CONCLUSIONS Statin adherence during the first year after a STEMI is a key factor in mortality, a period in which its assessment is needed beyond the prescription.

Abstract
Background Many older patients have a change in statin adherence-either an increase or a decrease-from before to after an acute myocardial infarction ( AMI ), but its association with mortality is unknown. Methods and Results Using Medicare administrative claims, a cohort of patients ≥66 years old with an AMI hospitalization from 2008 to 2010 was assembled. Statin adherence was measured for 180 days pre- AMI and 180 days post- AMI and categorized as severely nonadherent, moderately nonadherent, or adherent. Categorical change in statin adherence from pre- to post- AMI was assessed. Patients were then followed for up to 18 months for all-cause mortality. A Cox proportional hazards model was applied to estimate the effects of statin adherence change on all-cause mortality, adjusted for patient baseline characteristics. Of 101 011 eligible patients, 20% had a categorical increase in adherence, 16% decreased, and 14% remained nonadherent both pre- and post- AMI . Compared with patients who were always severely nonadherent (both pre- and post- AMI ), patients whose adherence increased from severely nonadherent to adherent (hazard ratio=0.83; 95% CI : 0.75-0.92) and patients who were always adherent (hazard ratio=0.88; 95% CI : 0.82-0.94) were less likely to die; patients whose adherence decreased from moderately nonadherent to severely nonadherent were more likely to die (hazard ratio=1.11; 95% CI : 1.01-1.22). Conclusions After an AMI , patients with decreased statin adherence had the worst mortality outcomes. However, patients with increased statin adherence had a similar risk of mortality compared with continuously adherent patients, suggesting that, even after an AMI , it is not too late to improve statin adherence.

Low adherence to statin treatment during the 1st year after an acute myocardial infarction is associated with increased 2nd-year mortality risk-an inverse probability of treatment weighted study on 54 872 patients. EUROPEAN HEART JOURNAL. CARDIOVASCULAR PHARMACOTHERAPY 2020; 7:141-147. [PMID: 32058542 PMCID: PMC7957903 DOI: 10.1093/ehjcvp/pvaa010] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/04/2019] [Revised: 01/13/2020] [Accepted: 02/06/2020] [Indexed: 11/18/2022]
Abstract
Aims Experiencing an acute myocardial infarction (AMI) is a life-threatening event and use of statins can reduce the probability of recurrence and improve long-term survival. However, the effectiveness of statins in the real-world setting may be lower than the reported efficacy in randomized clinical trials. Therefore, we aimed to investigate whether low statin treatment adherence during the year following an AMI episode is associated with increased 2nd-year mortality. Methods and results We analysed all 54 872 AMI patients aged ≥45 years, admitted to Swedish hospitals between 2010 and 2012, and who survive at least 1 year after the AMI episode. We defined low adherence as a medication possession ratio <50% or non-use of statins. Applying inverse probability of treatment weighting (IPTW), we investigated the association between low adherence and all-cause, cardiovascular disease (CVD), and non-CVD mortality during the 2nd year. Overall, 20% of the patients had low adherence during the 1st year and 8% died during the 2nd year. In the IPTW analysis, low adherence was associated with an increased risk of all-cause [absolute risk difference (ARD) = 0.048, number needed to harm (NNH) = 21, relative risk (RR) = 1.71], CVD (ARD = 0.035, NNH = 29, RR = 1.62), and non-CVD mortality (ARD = 0.013, NNH = 77, RR = 2.17). Conclusion In the real-world setting, low statin adherence during the 1st year after an AMI episode is associated with increased mortality during the 2nd year. Our results reaffirm the importance of achieving a high adherence to statin treatment after suffering from an AMI.

Getting to an ImprOved Understanding of Low-Density Lipoprotein-Cholesterol and Dyslipidemia Management (GOULD): Methods and baseline data of a registry of high cardiovascular risk patients in the United States. Am Heart J 2020; 219:70-77. [PMID: 31726422 DOI: 10.1016/j.ahj.2019.10.014] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Accepted: 10/23/2019] [Indexed: 11/19/2022]
Abstract
BACKGROUND Guidelines for managing patients with atherosclerotic cardiovascular disease (ASCVD) recommend statin therapy initially. Target levels/goals for low-density lipoprotein-cholesterol (LDL-C) were initially included, subsequently de-emphasized in 2013, and then re-introduced as thresholds, leading to confusion in clinical practice. We designed a multicenter, observational registry of patients with ASCVD, to describe and track LDL-C treatment patterns in the United States over time. METHODS Patients with ASCVD receiving any pharmacologic lipid-lowering therapy were eligible for enrollment in one of three cohorts: 1) currently receiving a proprotein convertase subtilisin/kexin type 9 inhibitor (PCSK9i), or not receiving PCSK9i with 2) LDL-C 70-99 mg/dL, or 3) LDL-C ≥100 mg/dL. Patients undergo a 1-year retrospective chart review, followed by chart reviews and phone interviews every 6 months for 2 years. RESULTS A total of 5006 patients were enrolled at 119 centers. Mean age was 68 years, 40% of patients were female, 86% were white, 80% had coronary artery disease, and 33% had type 2 diabetes mellitus. Among those not on a PCSK9i, high-intensity statins and ezetimibe were utilized in only 44% and 9%, respectively. Among women vs men, only 36.6% vs 48.2% received high-intensity statins (P < .001). Among patients on a PCSK9i, only one-third were receiving a statin, suggesting statin intolerance is a driver of PCSK9i use at present. CONCLUSION Our data on current practice in the US continue to illustrate that high-intensity statins and ezetimibe are underutilized in at-risk patients outside of clinical trials, particularly women. This study will track temporal changes in treatment patterns and identify opportunities for improvement in lipid management in patients with ASCVD.
