Purpose: This study clarifies the reality of persistence and adherence to statins in older Japanese people who initiated statin use and compares it between primary and secondary prevention cohorts. Methods: The nationwide study using the national claims database targeted statin initiators aged ≥55 years from FY2014 to FY2017 in Japan. Persistence and adherence to statins were analyzed overall and according to subgroups based on sex, age stratum, and prevention cohorts. Permissible gap of median days that statins were supplied per prescription to an individual was employed. Persistence rates were estimated as Kaplan–Meier estimates. Poor adherence during persistence was evaluated and defined as <0.8 of the proportion of days covered. Results: Of 3 675 949 initiators, approximately 80% initiated statin use with strong variants. The persistence rate at 1 year was 0.61. Poor adherence to statins during persistence was 8.0% in all patients and this value gradually improved with increasing age. Persistence rate and adherence were lower for the primary prevention cohort than for the secondary prevention cohort, and a notable sex difference was observed for the secondary prevention cohort, which was lower in females but was almost never and slightly observed in the primary prevention cohorts without and with high‐risk factors, respectively. Conclusions: Many statin initiators discontinued statins shortly following statin initiation but adherence while on statin therapy was good. Attentively watching older patients not to discontinue statins and listening to their reasons for discontinuation are required, especially for initiators in primary prevention and females in secondary prevention.

Margit Kriegbaum,1 Kasper Bering Liisberg,2 Helle Wallach-Kildemoes3 1Department of Public Health, 2Department of Media, Cognition, and Communication, 3Department of Pharmacy, University of Copenhagen, Copenhagen, Denmark Background: The media plays a role in shaping opinions about medical decisions, for example, whether to initiate or stop treatment. An association between negative media attention and statin discontinuation has been demonstrated, but it may differ depending on the reason for prescription and whether the user is new (incident) or long term (prevalent).Aim: The aim of this study is to explore whether a Danish newspaper article featuring the side effects of statins affects statin discontinuation in incident versus prevalent users, with the reason for prescription also taken into account.Methods: The study relies on a quasi-experimental design and uses registry data on statin purchases to explore discontinuation and treatment duration. As a proxy for reason for prescription, data on filled prescriptions and hospital diagnoses from a Danish registry were used. We compared statin discontinuation in all statin users in Denmark in 2007 before the media event (n=343,438) and after it in 2008 (n=404,052).Results: Compared to 2007, statin discontinuation among prevalent users in 2008 increased by 2.97 percentage points (pp). The change in discontinuation varied with the indication for statin use. Those with myocardial infarction had the smallest increase (1.98 pp) and those with hypercholesterolemia or primary hypertension had the largest increase (3.54 pp). Incident statin users had a higher level of discontinuation and a larger difference in discontinuation between 2007 and 2008. Compared to 2007, more people (5.52 pp) discontinued statin treatment in 2008. Again, those with myocardial infarction had the smallest decrease in statin discontinuation (1.49 pp), while those with a potential atherosclerotic condition (7.05 pp) and hypercholesterolemia or primary hypertension (6.10 pp) had the largest increase.Conclusion: Statin discontinuation increased in 2008 following a media event, but especially among individuals prescribed statins for primary prevention and among new statin users.

Objective: The purpose of this study was to identify patient characteristics and statin discontinuation-related factors in patients with hypercholesterolemia. Methods: A total of 532 patients (age mean+-SD: 57.4+-11.5 years; 52.4% women, 47.6% men) with hypercholesterolemia and statin discontinuation were included in this national cross-sectional noninterventional observational study. Data on socio-demographic characteristics of patients, cardiovascular risk factors, past treatment with and discontinuation of statin treatment were collected in one visit. Results: Mean+-SD duration of hypercholesterolemia was 4.9+-4.2 years at time of discontinuation of statin treatment. Statin treatment was initiated by cardiologists in the majority of cases (55.8%), whereas discontinuation of statin treatment was decided by patients in the majority of cases (73.7%), with patients with higher (at least secondary education, 80.4%) more likely than those with lower (only primary education, 69.7%) to decide to discontinue treatment (p=0.022). Negative information about statin treatment disseminated by TV programs-mostly regarding coverage of hepatic (38.0%), renal (33.8%), and muscular (32.9%) side effects (32.9%)-was the most common reason for treatment discontinuation. Conclusion: The decision to discontinue statin treatment was made at the patient's discretion in 74% of cases, with higher likelihood of patients with higher educational status deciding to discontinue treatment and switch to non-drug lipid-lowering alternatives. Cardiologists were the physicians most frequently responsible for the initiation of the statin treatment; coverage of several non-lifethreatening statin side effects by TV programs and patients' lack of information regarding high cholesterol and related risks were the leading factors predisposing to treatment discontinuation.

BackgroundContact with the healthcare system represents an opportunity for individuals who discontinue statins to re‐initiate treatment. To help identify opportunities for healthcare providers to emphasize the risk‐lowering benefits accrued through restarting statins, we determined the types of healthcare utilization associated with statin re‐initiation among patients with history of a myocardial infarction. Methods and ResultsMedicare beneficiaries with a statin pharmacy fill claim within 30 days of hospital discharge for a myocardial infarction in 2007 to 2012 (n=158 795) were followed for 182 days postdischarge to identify treatment discontinuation, defined as 60 continuous days without statins (n=24 461). Re‐initiation was defined as a statin fill within 365 days of the discontinuation date (n=13 136). Using a case‐crossover study design and each beneficiary as their own control, healthcare utilization during 0 to 14 days before statin re‐initiation (case period) was compared with healthcare utilization 30 to 44 days before statin re‐initiation (control period). The mean age of beneficiaries was 75.4 years; 52.8% were women and 81.9% were white. For routine healthcare utilization, the odds ratio (95% confidence interval) for statin re‐initiation associated with lipid panel testing was 2.65 (1.93–3.65), outpatient primary care was 1.31 (1.23–1.40), and outpatient cardiologist care was 1.38 (1.28–1.50). For acute healthcare utilization, the odds ratio (95% confidence interval) for statin re‐initiation associated with emergency department visits was 1.77 (1.31–2.40), coronary heart disease (CHD) hospitalizations was 3.16 (2.41–4.14) and non–coronary heart disease hospitalizations was 1.73 (1.49–2.01). ConclusionsThe weaker association of routine versus acute healthcare utilization with statin re‐initiation suggests missed opportunities to reinforce the importance of statin therapy for secondary prevention.

Statins are critical medications to prevent and treat cardiovascular disease2 and they are generally very well tolerated. In some instances, however, statin intolerance may limit use of these lifesaving medications. Statin intolerance has many definitions but is commonly diagnosed when a patient is unable to continue statin therapy due to perceived, or objectively documented, adverse effects. A very high rate of discontinuation of statin therapy warrants a closer look at the implications from the standpoint of cardiovascular risk in statin-intolerant patients, as well as an evaluation of the available options to help patients maintain their statin therapy and understand the potential benefits of such therapy.

Objective: To review the evidence of existing literature on the management of statin intolerance., Methods: We searched for literature pertaining to statin intolerance and treatments in PubMed. We reviewed articles published between 2005 and 2022., Results: Statin-associated myalgia is the most common adverse effect of statin therapy and the most common reason for statin discontinuation. The risk factors for statin intolerance include unexplained muscle pain with other lipid-lowering therapy, unexplained cramps, a history of increased creatine kinase levels, a family history of muscle symptoms, and a family history of muscle symptoms with lipid therapy. Vitamin D repletion and coenzyme Q supplementation may help alleviate the musculoskeletal effects of statins. Trials of different types of statins and different dosing regimens are recommended to improve tolerability. The use of statins in individuals who perform regular exercise requires closer attention to muscular symptoms and creatine kinase levels; however, it does not preclude the use of statins., Conclusion: Management of the adverse effects of statin therapy and improving statin tolerability are key to achieving optimum cardiovascular benefits. Identifying statin-associated adverse effects and managing them appropriately can reduce unnecessary statin discontinuation and subsequently provide longer cardiovascular protection., Competing Interests: Disclosure The authors have no multiplicity of interest to disclose., (Copyright © 2023 AACE.

Introduction: Statin therapy is the backbone of pharmacologic therapy for low-density lipoproteins cholesterol lowering and plays a pivotal role in cardiovascular disease prevention. Statin intolerance is understood as the inability to continue using a statin to reduce individual cardiovascular risk sufficiently, due to the development of symptoms or laboratory abnormalities attributable to the initiation or dose escalation of a statin. Muscle symptoms are the most common side effects observed. Areas covered: The main aim of this article is to present a review on published definitions of statin intolerance. In addition, a brief review on clinical aspects and risk factors of statin intolerance is provided and features for a common definition for statin intolerance are suggested. Expert opinion: A definition of statin intolerance by major drug regulatory agencies is not available. In clinical studies, different definitions are chosen and results are not comparable; different medical associations do not agree on one common definition. There is an unmet need to establish a common definition of statin intolerance to ensure an appropriate clinical use of this important drug class. Further work is required to develop a consensus definition on statin intolerance that could have significant positive impact on both research and clinical management.
