Abstract
Schizophrenia is one of the most debilitating mental disorders, and its diagnosis and treatment present significant challenges. Several clinical trials have previously evaluated the effectiveness of simvastatin, a lipid-lowering medication, as a novel add-on treatment for schizophrenia. However, treatment effects varied highly between patients and over time. In the present study, we aimed to identify biomarkers of response to simvastatin in recent-onset schizophrenia patients. To this end, we profiled relevant immune and metabolic markers in patient blood samples collected in a previous clinical trial (ClinicalTrials.gov: NCT01999309) before simvastatin add-on treatment was initiated. Analysed sample types included serum, plasma, resting-state peripheral blood mononuclear cells (PBMCs), as well as PBMC samples treated ex vivo with immune stimulants and simvastatin. Associations between the blood readouts and clinical endpoints were evaluated using multivariable linear regression. This revealed that changes in insulin receptor (IR) levels induced in B-cells by ex vivo simvastatin treatment inversely correlated with in vivo effects on cognition at the primary endpoint of 12 months, as measured using the Brief Assessment of Cognition in Schizophrenia scale total score (standardised β ± SE = -0.75 ± 0.16, P = 2.2 × 10-4, Q = 0.029; n = 21 patients). This correlation was not observed in the placebo group (β ± SE = 0.62 ± 0.39, P = 0.17, Q = 0.49; n = 14 patients). The candidate biomarker explained 53.4 % of the variation in cognitive outcomes after simvastatin supplementation. Despite the small sample size, these findings suggest a possible interaction between the insulin signalling pathway and cognitive effects during simvastatin therapy. They also point to opportunities for personalized schizophrenia treatment through patient stratification.

Abstract
INTRODUCTION The increase in statin use, since their introduction, has been rapid and the broadening of indications has occurred seemingly without restriction. Once established on statin therapy, there is sparse research on discontinuation. Trials do not often address benefit in later life, or the impact of a life-limiting diagnosis. Data on primary prevention suggest that 100 patients need treatment for 2.5 years to prevent one major adverse cardiovascular event. Acknowledging this, we sought to determine the use of statins in a cohort of older adults with cancer, to highlight prevalence, and suggest a role for deprescribing. MATERIALS AND METHODS Data were retrospectively collected from a prospectively maintained database of patients attending a single centre Geriatric Oncology clinic. Data collected included sex, age, cancer type and stage, systemic anti-cancer therapy (SACT) recommendation, comorbidities, non-SACT medications, and overall survival. For those receiving statin therapy, data were separated into primary prevention and stage IV cancer. RESULTS In the group studied (n = 230), 135 (59%) were prescribed a statin, with 79 (58%) for primary prevention. Ninety-three (40%) had stage IV cancer. Of the 230 patients, 134 (58%) were recommended SACT. Within the primary prevention group, the median age was 79 years. Twenty-seven patients (34%) had stage III disease, while 36 (46%) had stage IV disease. Thirteen (16%) had diabetes mellitus. The median number of medications was seven (Interquartile range 5). Fifty patients (63%) were recommended SACT. In terms of survival, 31 (50%) were alive at one year, 18 (29%) alive at two years, and 14 (23%) alive beyond two and a half years. Within the stage IV disease group, 59 out of 93 (63%) were receiving statin therapy; 35 (59%) for primary prevention and seven (8%) for diabetes mellitus. Fifty-eight (63%) were recommended SACT. Twenty-four (29%) were alive at one year, 17 (21%) alive at two years, and 13 (16%) alive beyond two and a half years. DISCUSSION Statin therapy is prevalent and continues into older age. Available data regarding statin therapy in older adults and survival seen in this study support deprescribing in primary prevention and life-limiting illness, such as stage IV cancer.

Abstract
Selecting individuals for preventive lipid-lowering therapy is presently governed by the 10-year risk model. Once a prespecified level of cardiovascular disease risk is equaled or exceeded, individuals become eligible for preventive lipid-lowering therapy. A key limitation of this model is that only a small minority of individuals below the age of 65 years are eligible for therapy. However, just under one-half of all cardiovascular disease events occur below this age. Additionally, in many, the disease that caused their events after 65 years of age developed and progressed before 65 years of age. The causal-benefit model of prevention identifies individuals based both on their risk and the estimated benefit from lowering atherogenic apoB lipoprotein levels. Adopting the causal-benefit model would increase the number of younger subjects eligible for preventive treatment, would increase the total number of cardiovascular disease events prevented at virtually the same number to treat, and would be cost-effective.

Patient Prefer Adherence 2024; 18:15-27. [PMID: 38196947 PMCID: PMC10773265 DOI: 10.2147/ppa.s432448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/26/2023] [Accepted: 12/10/2023] [Indexed: 01/11/2024] Open
Abstract
Background and Purpose Evidence for statin use for primary cardiovascular disease prevention in older adults is limited. When evidence on risk-benefit profile of a medication is uncertain, using it or not becomes a preference-sensitive decision. We aimed to assess and explore patient perspectives on continuation and discontinuation of statins used for primary cardiovascular prevention in older adults. Patients and Methods We used a convergent mixed-methods design, conducting in parallel a survey among 47 patients and three focus groups (FGs) with 14 patients total. We recruited patients aged ≥65 years and taking a statin for primary cardiovascular prevention. The survey and FGs aimed to assess and explore patient experiences of statin use, and views on statin continuation and discontinuation, including patient decision-making. Quantitative and qualitative data were first analyzed separately - descriptive statistics for quantitative data and thematic analysis for qualitative data - and then integrated to create metainferences, using joint displays. Results Forty-one percent of patients (N=19) were reluctant to discontinue the statin, whereas 22% (N=10) were willing to try discontinuing it. A reason to continue the statin was its perceived necessity, while self-estimated low cardiovascular risk and wish to reduce medication burden were given as reasons to discontinue it. Lack of expertise assumed by the patients to decide about statin continuation or discontinuation, uncertainty about statin indication, and fear of having a cardiovascular event after discontinuation made many patients uncertain about deciding to continue or discontinue the statin. In this context, 70% (N=33) would rather have their physician choose for them, and 94% (N=44) would continue taking the statin for as long as their physician told them to do so. Conclusion This study highlights factors that influence patient willingness to continue or discontinue statins, patient uncertainty about statin continuation or discontinuation, and the important role physicians play in the decision-making process.

Abstract
AIM We aimed to assess the cost effectiveness of four different lipid-lowering strategies for primary prevention of coronary heart disease initiated at ages 30, 40, 50, and 60 years from the UK National Health Service perspective. METHODS We developed a microsimulation model comparing the initiation of a lipid-lowering strategy to current standard of care (control). We included 458,692 participants of the UK Biobank study. The four lipid-lowering strategies were: (1) low/moderate-intensity statins; (2) high-intensity statins; (3) low/moderate-intensity statins and ezetimibe; and (4) inclisiran. The main outcome was the incremental cost-effectiveness ratio for each lipid-lowering strategy compared to the control, with 3.5% annual discounting using 2021 GBP (£); incremental cost-effectiveness ratios were compared to the UK willingness-to-pay threshold of £20,000-£30,000 per quality-adjusted life-year. RESULTS The most effective intervention, low/moderate-intensity statins and ezetimibe, was projected to lead to a gain in quality-adjusted life-years of 0.067 per person initiated at 30 and 0.026 at age 60 years. Initiating therapy at 40 years of age was the most cost effective for all lipid-lowering strategies, with incremental cost-effectiveness ratios of £2553 (95% uncertainty interval: 1270, 3969), £4511 (3138, 6401), £11,107 (8655, 14,508), and £1,406,296 (1,121,775, 1,796,281) per quality-adjusted life-year gained for strategies 1-4, respectively. Incremental cost-effectiveness ratios were lower for male individuals (vs female individuals) and for people with higher (vs lower) low-density lipoprotein-cholesterol. For example, low/moderate-intensity statin use initiated from age 40 years had an incremental cost-effectiveness ratio of £5891 (3822, 9348), £2174 (772, 4216), and was dominant (i.e. cost saving; -2,760, 350) in female individuals with a low-density lipoprotein-cholesterol of ≥ 3.0, ≥ 4.0 and ≥ 5.0 mmol/L, respectively. Inclisiran was not cost effective in any sub-group at its current price. CONCLUSIONS Low-density lipoprotein-cholesterol lowering from early ages is a more cost-effective strategy than late intervention and cost effectiveness increased with the increasing lifetime risk of coronary heart disease.

Abstract
OBJECTIVES Despite guidelines endorsing statin and single antiplatelet therapy (SAPT) therapy post-carotid endarterectomy (CEA), these medications may be either under or inappropriately prescribed. We determined rates of new statin prescriptions as well as change in antiplatelet therapy (APT) regimen at discharge. We identified characteristics associated with these occurrences. DESIGN We performed a retrospective Vascular Quality Initiative registry analysis of more than 125 000 patients who underwent CEA from 2013 to 2021. SETTING The Vascular Quality Initiative is a multicentre registry database including academic and community-based hospitals throughout the USA. PARTICIPANTS Patients age≥18 years undergoing CEA with available statin and APT data (preprocedure and postprocedure) were included. PRIMARY AND SECONDARY OUTCOME MEASURES We determined overall rates of statin and APT prescription at discharge. Multivariate logistic regression was used to determine clinical and demographic characteristics that were mostly associated with new statin prescription or changes in APT regimen at discharge. RESULTS Study participants were predominantly male (61%) and White (90%), with a mean age of 70.6±9.1. 13.1% of participants were not on statin therapy pre-CEA, and 48% of these individuals were newly prescribed one. Statin rates steadily increased throughout the study period: 36.2% in 2013 to 62% in 2021. A higher likelihood of new statin prescription was associated with non-race, diabetes, coronary heart disease, stroke, TIA and a non-elective indication. Older age, female gender, chronic obstructive pulmonary disease and prior carotid revascularisation were associated with a lower likelihood of new statin prescription. Nearly all participants were discharged on APT (63% SAPT and 37% dual antiplatelet therapy, DAPT). Among these individuals, 16% were discharged on a regimen that was different from the one on admission (11 947 (10.7%) of patients were upgraded to DAPT and 5813 (5.2%) were downgraded to SAPT). CONCLUSIONS Although statin use has substantially improved following CEA, more than half of individuals not on a statin preprocedure remained this way at discharge. In addition, DAPT at discharge was frequent, a quarter of whom were on SAPT preprocedure. Further efforts are needed to improve rates of new statin prescriptions, ensure appropriate APT intensity at discharge and determine how different discharge APT regimens impact outcomes.

Abstract
OBJECTIVE To assess trends in abdominal aortic aneurysm (AAA) hospital admissions, interventions, and aneurysm related mortality in England, and to examine the impact of endovascular repair on mortality for the years 1998 - 2020. METHODS Hospital admission and operative approach (endovascular aortic aneurysm repair, or open surgical repair [OSR]) using Hospital Episodes Statistics (HES), and aneurysm related mortality data from the Office for National Statistics for England standardised to the 2013 European Standard Population, were analysed using linear regression and Joinpoint regression analyses. Aneurysm related mortality was compared between the pre-endovascular era (1998 - 2010) and the endovascular era (2011 - 2019). RESULTS A declining trend in hospital admission incidence was observed, mainly due to a decline in ruptured admissions from 34.6 per 100 000 (95% confidence interval [CI] 33.5 - 35.6) to 13.5 per 100 000 (95% CI 12.9 - 14.2; βi = -1.04, r2 = .97, p < .001). Operative interventions have been declining over the last 23 years mainly due to the statistically significant decline in open procedures (41.2 per 100 000 in 2000 [95% CI 40 - 42.3] to 9.6 per 100 000 [95% CI 9.1 - 10.1]; βi = -1.92, r2 = .95; p < .001). There was an increasing trend toward endovascular procedures (5.8 per 100 000 [95% CI 5.3 - 6.2] in 2006 to 16.9 per 100 000 [95% CI 16.2 - 17.5] in 2020; βi = .82, r2 = .30, p = .040). Reductions in aneurysm related mortality due to AAAs were observed for males and females, irrespective of age and rupture status. CONCLUSION A significant decrease in hospital admissions for AAAs was observed over the last 23 years in England, paralleled by a shift toward endovascular repair and a decline in OSR. Declines in aneurysm related mortality were observed overall, and in the endovascular era irrespective of age, sex, and rupture status.

Abstract
Immune-mediated necrotising myopathy (IMNM) is a severe and poorly understood complication of statin use. Prompt management with immunosuppressive treatment is often needed to control the condition, which differs from the management of the more commonly recognised statin-induced myopathy. We present a case report and brief review of the literature regarding the pathogenesis, diagnosis, and management of anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) positive IMNM (HMGCR IMNM). There are no randomised clinical trials, but several smaller studies and cases suggest a triple therapy of corticosteroids, IVIG, and a corticosteroid-sparing immunosuppressant appears efficacious in patients with IMNM and proximal weakness. The mechanism of statin-induced IMNM is uncertain, and this is further complicated by the reports of HMGCR IMNM in statin-naïve patients, including children. We present a case of biopsy-confirmed HMGCR IMNM in a woman taking daily statins for treatment of hypercholesterolaemia for 4 years. She presented with symptoms consistent with a urinary tract infection (UTI), including muscle weakness. She was treated as an isolated case of UTI. One month later, she presented again with worsening weakness in her shoulders and hips. Creatine kinase was elevated, and MRI showed increased signal with STIR sequences in both thighs. Anti-HMGCR was positive and leg biopsy-confirmed necrotising changes. Stopping her statin prescription and a short course of prednisolone did not improve her muscle weakness. Adding methotrexate resulted in eventual resolution of her symptoms. IMNM should be considered as a differential in any patient taking statins presenting with muscle weakness, and this case suggests that immunosuppressant therapy in addition to cessation of statins is effective at treating IMNM. Clinical trials are needed to further investigate the efficacy of different combinations of immunosuppressants.

Abstract
BACKGROUND While several definitions exist for multimorbidity, frailty or polypharmacy, it is yet unclear to what extent single healthcare markers capture the complexity of health-related needs in older people in the community. We aimed to identify and characterise older people with complex health needs based on healthcare resource use (unplanned hospitalisations or polypharmacy) or frailty using large population-based linked records. METHODS In this cohort study, data was extracted from UK primary care records (CPRD GOLD), with linked Hospital Episode Statistics inpatient data. People aged > 65 on 1st January 2010, registered in CPRD for ≥ 1 year were included. We identified complex health needs as the top quintile of unplanned hospitalisations, number of prescribed medicines, and electronic frailty index. We characterised all three cohorts, and quantified point-prevalence and incidence rates of preventive medicines use. RESULTS Overall, 90,597, 110,225 and 116,076 individuals were included in the hospitalisation, frailty, and polypharmacy cohorts respectively; 28,259 (5.9%) were in all three cohorts, while 277,332 (58.3%) were not in any (background population). Frailty and polypharmacy cohorts had the highest bi-directional overlap. Most comorbidities such as diabetes and chronic kidney disease were more common in the frailty and polypharmacy cohorts compared to the hospitalisation cohort. Generally, prevalence of preventive medicines use was highest in the polypharmacy cohort compared to the other two cohorts: For instance, one-year point-prevalence of statins was 64.2% in the polypharmacy cohort vs. 60.5% in the frailty cohort. CONCLUSIONS Three distinct groups of older people with complex health needs were identified. Compared to the hospitalisation cohort, frailty and polypharmacy cohorts had more comorbidities and higher preventive therapies use. Research is needed into the benefit-risk of different definitions of complex health needs and use of preventive therapies in the older population.

Abstract
Studies showing that the management of dyslipidemia is suboptimal are hampered by their cross-sectional design or short follow-up. Using recent data from a population-based cohort with a 10-year follow-up, we assessed the use of statins, including their intensity. We used data from the CoLaus|PsyColaus study, involving 4,655 participants at baseline (2003 to 2006) and 3,587 at 10-year follow-up (2014 to 2017). We assessed the cardiovascular risk of participants according to established guidelines from the European Society of Cardiology (ESC) and from the American Heart Association/American College of Cardiology and estimated 10-year cardiovascular risk using corresponding risk scores, Systemic Coronary Risk Evaluation risk prediction model and Pooled Cohort Equations. We first determined eligibility for statins and adherence to recommendations at 2 time periods. Additionally, we assessed the prevalence of statin users from 2014 to 2017 in persons without atherosclerotic cardiovascular disease at baseline and who developed it during the follow-up (secondary prevention). A total of 219 participants developed a first atherosclerotic cardiovascular disease during follow-up. Statin use in eligible subjects was 25.9% and 24.0% from 2003 to 2006 and 35.9% and 26.3% from 2014 to 2017, according to ESC and American Heart Association/American College of Cardiology guidelines, respectively. Per ESC guidelines, only 28.2% of treated persons achieved low-density lipoproteins cholesterol target levels from 2014 to 2017 (15.8% from 2003 to 2006), and women less frequently attained goals. Only 18% of subjects used high-intensity statins from 2014 to 2017, with women less often receiving them (14% vs 22%). In secondary prevention, only 74% of eligible subjects were using statins. In conclusion, based on contemporaneous data, management of dyslipidemia is suboptimal, including in secondary prevention, especially in women who are less frequently treated and, if treated, less frequently receive high-intensity treatment.

Statin-related adverse drug reactions in UK primary care consultations: A retrospective cohort study to evaluate the risk of cardiovascular events and all-cause mortality. Br J Clin Pharmacol 2022; 88:4902-4914. [PMID: 35695656 PMCID: PMC9796911 DOI: 10.1111/bcp.15438] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2022] [Revised: 04/28/2022] [Accepted: 06/05/2022] [Indexed: 01/07/2023] Open
Abstract
AIMS To investigate the risk of cardiovascular disease (CVD) events and all-cause mortality in patients with statin-related adverse drug reaction (ADR) consultation in primary care and examine whether different treatments following the ADR affect subsequent outcomes. METHODS This was a retrospective cohort study of statin users between 2004 and 2019 using IQVIA Medical Research Data (formally known as the THIN database). Patients with statin-related ADR consultation were matched by propensity score (1:1) to statin users without ADR consultation based on demographics, comorbidities and concomitant medication. Cox proportional hazard regression was used to compare the risk of subsequent CVD event and all-cause mortality, stratified by history of CVD. In the secondary analysis among patients with statin-related ADR, treatment changes within a 1-year period following the ADR were examined and the outcomes were compared between different treatment groups. RESULTS Among 1 564 687 statin users, 19 035 (1.22%) had a statin-related ADR consultation in primary care. The mean (standard deviation) follow-up time was 6.32 (3.74) years and 5.31 (3.83) years for CVD primary and secondary prevention cohorts, respectively. Statin-related ADR consultation was associated with subsequent CVD events in both cohorts (adjusted hazard ratio [HR] of 1.39 [95% CI 1.23, 1.57] and 1.34 [95% CI 1.25,1.42], respectively). In the secondary analysis among patients with statin-related ADR consultation, we found that (i) continued statin prescription or combination of any statin with additional lipid-lowering treatment (LLT) and (ii) other LLT only were associated with lower risks of CVD event (adjusted HR 0.71 [95% CI 0.64, 0.78] and 0.75 [95% CI 0.62, 0.92], respectively) and all-cause mortality (adjusted HR 0.46 [95% CI 0.42, 0.50] and 0.52 [95% CI, 0.43, 0.64], respectively), compared to discontinuation of all LLT. CONCLUSION Statin-related ADR was associated with an increased risk of subsequent CVD event, indicating that these patients should be monitored more closely. Continued lipid-lowering medication is of importance to protect against CVD events and mortality.

Front Pharmacol 2022; 13:888677. [PMID: 36313311 PMCID: PMC9614045 DOI: 10.3389/fphar.2022.888677] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Accepted: 10/03/2022] [Indexed: 11/13/2022] Open
Abstract
Background and aims: Medication usage varies according to prescribing behavior, professional recommendations, and the introduction of new drugs. Local surveillance of medication usage may be useful for understanding and comparing prescribing practices by healthcare providers, particularly in countries such as Australia that are in the process of enhancing nationwide data linkage programs. We sought to investigate the utility of electronic hospital admission data to investigate local trends in medication use, to determine similarities and differences with other Australian studies, and to identify areas for targeted interventions. Methods: We performed a retrospective longitudinal analysis using combined data from a hospital admissions administrative dataset from a large tertiary teaching hospital in Adelaide, South Australia and a hospital administrative database documenting medication usage matched for the same set of patients. All adult admissions over a 12-year period, between 1 January 2007 and 31st December 2018, were included in the study population. Medications were categorized into 21 pre-defined drug classes of interest according to the ATC code list 2021. Results: Of the 692,522 total admissions, 300,498 (43.4%) had at least one recorded medication. The overall mean number of medications for patients that were medicated increased steadily from a mean (SD) of 5.93 (4.04) in 2007 to 7.21 (4.98) in 2018. Results varied considerably between age groups, with the older groups increasing more rapidly. Increased medication usage was partly due to increased case-complexity with the mean (SD) Charlson comorbidity index increasing from 0.97 (1.66) in 2007-to-2012 to 1.17 (1.72) in 2013-to-2018 for medicated patients. Of the 21 medication classes, 15 increased (p < 0.005), including antithrombotic agents; OR = 1.18 [1.16–1.21], proton pump inhibitors; OR = 1.14 [1.12–1.17], statins; OR = 1.12; [1.09–1.14], and renin-angiotensin system agents; OR = 1.06 [1.04–1.08], whilst 3 decreased (p < 0.005) including anti-inflammatory drugs (OR = 0.55; 99.5% CI = 0.53–0.58), cardiac glycosides (OR = 0.81; 99.5% CI = 0.78–0.86) and opioids (OR = 0.82; 99.5% CI = 0.79–0.83). The mean number of medications for all admissions increased between 2007 and 2011 and then declined until 2018 for each age group, except for the 18-to-35-year-olds. Conclusion: Increased medication use occurred in most age groups between 2007 and 2011 before declining slightly even after accounting for increased comorbidity burden. The use of electronic hospital admission data can assist with monitoring local medication trends and the effects of initiatives to enhance the quality use of medicines in Australia.

Effects of general and central adiposity on circulating lipoprotein, lipid, and metabolite levels in UK Biobank: A multivariable Mendelian randomization study. THE LANCET REGIONAL HEALTH. EUROPE 2022; 21:100457.

Abstract
Background The direct effects of general adiposity (body mass index (BMI)) and central adiposity (waist-to-hip-ratio (WHR)) on circulating lipoproteins, lipids, and metabolites are unknown. Methods We used new metabolic data from UK Biobank (N=109,532, a five-fold higher N over previous studies). EDTA-plasma was used to quantify 249 traits with nuclear-magnetic-resonance spectroscopy including subclass-specific lipoprotein concentrations and lipid content, plus pre-glycemic and inflammatory metabolites. We used univariable and multivariable two-stage least-squares regression models with genetic risk scores for BMI and WHR as instruments to estimate total (unadjusted) and direct (mutually-adjusted) effects of BMI and WHR on metabolic traits; plus effects on statin use and interaction by sex, statin use, and age (proxy for medication use). Findings Higher BMI decreased apolipoprotein B and low-density lipoprotein cholesterol (LDL-C) before and after WHR-adjustment, whilst BMI increased triglycerides only before WHR-adjustment. These effects of WHR were larger and BMI-independent. Direct effects differed markedly by sex, e.g., triglycerides increased only with BMI among men, and only with WHR among women. Adiposity measures increased statin use and showed metabolic effects which differed by statin use and age. Among the youngest (38-53y, statins-5%), BMI and WHR (per-SD) increased LDL-C (total effects: 0.04-SD, 95%CI=-0.01,0.08 and 0.10-SD, 95%CI=0.02,0.17 respectively), but only WHR directly. Among the oldest (63-73y, statins-29%), BMI and WHR directly lowered LDL-C (-0.19-SD, 95%CI=-0.27,-0.11 and -0.05-SD, 95%CI=-0.16,0.06 respectively). Interpretation Excess adiposity likely raises atherogenic lipid and metabolite levels exclusively via adiposity stored centrally, particularly among women. Apparent effects of adiposity on lowering LDL-C are likely explained by an effect of adiposity on statin use.

Abstract
Purpose The purpose of this study was to evaluate the relationship between statin use and glaucoma-related traits. Methods In a cross-sectional study, we included 118,153 UK Biobank participants with data on statin use and corneal-compensated IOP. In addition, we included 192,283 participants (8982 cases) with data on glaucoma status. After excluding participants with neurodegenerative diseases, 41,638 participants with macular retinal nerve fiber layer thickness (mRNFL) and 41,547 participants with macular ganglion cell inner plexiform layer thickness (mGCIPL) were available for analysis. We examined associations of statin use with IOP, mRNFL, mGCIPL, and glaucoma status utilizing multivariable-adjusted regression models. We assessed whether a glaucoma polygenic risk score (PRS) modified associations. We performed Mendelian randomization (MR) experiments to investigate associations with various glaucoma-related outcomes. Results Statin users had higher unadjusted mean IOP ± SD than nonusers, but in a multivariable-adjusted model, IOP did not differ by statin use (difference = 0.05 mm Hg, 95% confidence interval [CI] = -0.02 to 0.13, P = 0.17). Similarly, statin use was not associated with prevalent glaucoma (odds ratio [OR] = 1.05, 95% CI = 0.98 to 1.13). Statin use was weakly associated with thinner mRNFL (difference = -0.15 microns, 95% CI = -0.28 to -0.01, P = 0.03) but not with mGCIPL thickness (difference = -0.12 microns, 95% CI = -0.29 to 0.05, P = 0.17). No association was modified by the glaucoma PRS (Pinteraction≥ 0.16). MR experiments showed no evidence for a causal association between the cholesterol-altering effect of statins and several glaucoma traits (inverse weighted variance P ≥ 0.14). Conclusions We found no evidence of a protective association between statin use and glaucoma or related traits after adjusting for key confounders.

Abstract
BACKGROUND Understanding trends in the incidence and outcomes of myocardial infarction and stroke, and how these are influenced by changes in cardiovascular risk factors can inform health policy and healthcare provision. METHODS We identified all patients 30 years or older with myocardial infarction or stroke in Scotland. Risk factor levels were determined from national health surveys. Incidence, potential impact fractions and burden attributable to risk factor changes were calculated. Risk of subsequent fatal and non-fatal events (myocardial infarction, stroke, bleeding and heart failure hospitalization) were calculated with multi-state models. FINDINGS From 1990 to 2014, there were 372,873 (71±13 years) myocardial infarctions and 290,927 (74±13 years) ischemic or hemorrhagic strokes. Age-standardized incidence per 100,000 fell from 1,069 (95% confidence interval, 1,024-1,116) to 276 (263-290) for myocardial infarction and from 608 (581-636) to 188 (178-197) for ischemic stroke. Systolic blood pressure, smoking and cholesterol decreased, but body-mass index increased, and diabetes prevalence doubled. Changes in risk factors accounted for a 74% (57-91%) reduction in myocardial infarction and 68% (55-83%) reduction in ischemic stroke. Following myocardial infarction, the risk of death decreased (30% to 20%), but non-fatal events increased (20% to 24%) whereas the risk of both death (47% to 34%) and non-fatal events (22% to 17%) decreased following stroke. INTERPRETATION Over the last 25 years, substantial reductions in myocardial infarction and ischemic stroke incidence are attributable to major shifts in risk factor levels. Deaths following the index event decreased for both myocardial infarction and stroke, but rates remained substantially higher for stroke. FUNDING British heart foundation.

Abstract
OBJECTIVE This study aimed to estimate trends in cardiovascular disease risk factors by BMI category among adults in England (n = 115,860). METHODS Risk factors included cigarette smoking, hypertension, total diabetes, and raised total cholesterol. Risk factor prevalence was computed in the following four 4-year time periods: 2003-2006; 2007-2010; 2011-2014; and 2015-2018. Change was computed as the difference between the first and last time periods, expressed in percentage points (PP). RESULTS Hypertension remained at a stable level among men with normal weight but decreased among men with obesity (-4.1 PP; 95% CI: -7.1 to -1.0). Total diabetes remained at a stable level among adults with normal weight but increased among adults with obesity (men: 3.5 PP, 95% CI: 1.2 to 5.7; women: 3.6 PP, 95% CI: 1.8 to 5.4). Raised total cholesterol decreased in all BMI groups but fell more sharply among women with obesity (-21 PP; 95% CI: -25 to -17) versus their counterparts with normal weight (-16 PP; 95% CI: -18 to -14). CONCLUSIONS Greater reductions in hypertension and raised total cholesterol among adults with overweight and obesity partially reflect improvements in screening, treatment, and control among those at highest cardiovascular risk. Higher levels of risk factor prevalence among adults with overweight and obesity, in parallel with rising diabetes, highlight the importance of national prevention efforts to combat the public health impact of excess adiposity.

Abstract
BACKGROUND Disparities in mortality rates according to socioeconomic position (SEP) have been rising in England. We describe the association between recent changes in socioeconomic inequality and trends in mortality disparities for different age and sex groups at small-area level in England. METHODS Vital registration data from the Office for National Statistics on resident population size and number of deaths in each Lower Super Output Area (LSOA) in England from 2002 to 2018 were stratified by sex and 5-year age group. We grouped LSOA into ventiles of the Index of Multiple Deprivation (IMD), our indicator of SEP. We examined time trends in smoothed mortality rates, using 3 year moving averages for the period 2003-2017, by age across the IMD distribution. We measured mortality inequalities using the ratio of mortality rates between different deprivation groups. We calculated mortality rate ratios between the most and the least deprived 10% of areas (Total Inequality) and between the median and least deprived (Lower Inequality) 10% of areas by year, gender and age group, to examine where in the distribution of deprivation trends in mortality inequality arose. FINDINGS Among <1 year olds, the inequality in mortality rates between the poorest 10% of LSOAs and the richest 10% of LSOAs fell between 2003 and 2017 by 22•7% for men and 22•8% for women. The largest inequalities were observed among 40 to 54 year olds. This inequality increased over the study period - from 3•2 times higher mortality rates for men in the most as opposed to the least deprived 10% of LSOAs in 2003 to 3•3 times in 2017. The rise was from 2•4 to 2•6 for women. Age groups ≥65 years, who experience the highest mortality risk, had low but rising inequality. Men and women aged 65 to 79 living in the most deprived LSOAs had a mortality rate 1•9 times higher than the least deprived in 2003 but this had increased to 2•2 times higher for women and 2•3 times higher for men by 2017. This was due to rising inequality in both halves of the distribution - between the top 10% of LSOA and the middle, and between the middle and the bottom 10% of LSOA. INTERPRETATION Overall mortality inequality rose in England but there were substantial differences in the trends for specific age and sex groups. Infant and child mortality inequality fell. At older ages, mortality inequality rose across cohorts, although in different ways, as each cohort's exposure to life-course to labour market inequality has differed. Policy goals of reducing mortality inequality will be best met by a focus on the risk factors that are specific to particular age and deprivation groups.

Abstract
This study aimed to determine the dose-response relationship between the levels of statin exposure and the incidence of Alzheimer's disease (AD). We included 119,013 Korean adults (≥ 60 years old) using a database from the Korean National Health Insurance Service (2002-2013). Statin exposure was treated as a time-varying variable. Incidence of AD was defined by the first claim code for AD with anti-Alzheimer drugs. AD occurred in 9467 cases during a median 7.2 years of follow-up. Overall, statin use was not associated with an increased risk of AD incidence [adjusted hazard ratio (aHR) = 1.04; 95% confidence interval (CI) = 0.99-1.10]. When examined by level of statin exposure, statin prescription < 540 days during a 2-year window time was associated with a higher risk for incidence of AD compared to statin non-use. However, days of prescription ≥ 540 and cumulative defined daily dose ≥ 540 of statin were associated with decreased risk of AD [aHR (95% CI) = 0.87 (0.80-0.95) and 0.79 (0.68-0.92), respectively]. Our findings indicate that less persistent statin use is associated with increased risk of AD, whereas persistent and adherent statin use is associated with decreased risk of AD.

Abstract
Lipid-lowering medications comprise standard of care in the prevention of cardiovascular disease. This study examined the trends in the utilization of statin and non-statin medications in the Australian general population between 2013 and 2019. Pharmacoepidemiological analyses were performed using pharmacy dispensing data from Australian Pharmaceutical Benefits Scheme. One-year prevalence and incidence of statin and non-statin prescribing patterns were reported, and relative variations in prescribing examined via Poisson regression modelling. The one-year prevalence of statins' prescriptions decreased between 2013-2019 by 5.5% (from 25.0%-19.5%). Females were less likely than males to be prescribed statins (rate ratio [RR]=0.90, 95% confidence interval [CI] 0.89-0.91). The one-year prevalence of ezetimibe alone, and in combination with statins, increased consistently from 2013-2019 from 1.5%-3.6% (P<0.01) and 0.1%-1.1% (P<0.01), respectively. The prevalence was higher among those aged 61-80 years (RR=1.20, 95%CI 1.10-1.21) and those aged older than 80 years (RR=1.34, 95%CI 1.22-1.47), when compared to people aged <60 years. The incidence of ezetimibe prescriptions was highest in people aged 61-80 years (RR=1.36, 95%CI 1.31-1.41) compared to those aged <60 years. The one-year prevalence of proprotein convertase subtilisin/kexin type 9 inhibitor prescriptions was highest among those aged 46-60 years (RR=1.24, 95%CI 0.97-4.97) compared to people aged <46 and >60 years. Females were less likely than males to be prescribed a proprotein convertase subtilisin/kexin type 9 inhibitor (RR=0.87, 95%CI 0.75-0.98). Statins remain the most prevalent lipid-lowering medication prescribed in Australia. The prescribing of non-statin medications remains low, but is increasing.

Abstract
PURPOSE This study assessed associations of the use of statins for primary prevention with cardiovascular outcomes among adults ages ≥70 years. METHODS In a retrospective population-based cohort study, new users of statins without cardiovascular disease or diabetes mellitus were stratified by ages ≥70 years and <70 years. Using a time-dependent approach, adherence to statins was evaluated according to the proportion of days covered: <25%, 25%-50%, 50%-75%, and ≥75%. We assessed associations of statin therapy with increased risk of new-onset diabetes mellitus and with decreased risks of major adverse cardiovascular events and all-cause mortality. RESULTS Of 42,767 new users of statins, 5970 (14%) were ages ≥70 years. The incident rates of major adverse cardiovascular events, all-cause mortality, and new-onset diabetes mellitus in the highest to lowest proportion of days covered categories were 16.9%, 16.7%, and 9.4% and 6.3%, 1.7%, and 9.4%, respectively. For the older group, the adjusted hazard ratios of major adverse cardiovascular events and mortality were significantly decreased for the highest adherence group (proportion of days covered ≥75%): 0.71 (0.57-0.88) and 0.68 (0.54-0.84), respectively. The respective hazard ratios were less favorable for the younger group: 0.80 (0.68-0.93) and 0.74 (0.58-1.03). The risk of new-onset diabetes mellitus was increased for the younger but not the older group. CONCLUSIONS Statin use for primary prevention was associated with cardiovascular benefit in adults ages ≥70 years without a significant risk for the development of diabetes. These data may support the use of statin therapy for primary prevention in the elderly.

Abstract
Even with increasing awareness of sex-related differences in atherosclerotic cardiovascular disease (ASCVD), it remains unclear whether the progression of coronary atherosclerosis differs between women and men. We sought to compare coronary artery calcium (CAC) progression between women and men. From a retrospective, multicentre registry of consecutive asymptomatic individuals who underwent CAC scoring, we identified 9,675 men and 1,709 women with follow-up CAC scoring. At baseline, men were more likely to have a CAC score >0 than were women (47.8% vs. 28.6%). The probability of CAC progression at 5 years, defined as [√CAC score (follow-up)-√CAC score (baseline)] ≥2.5, was 47.4% in men and 29.7% in women (p<0.001). When we stratified subjects according to the 10-year ASCVD risk (<5%, ≥5% and <7.5%, and ≥7.5%), a sex difference was observed in the low risk group (CAC progression at 5 years, 37.6% versus 17.9%; p<0.001). However, it became weaker as the 10-year ASCVD risk increased (64.2% versus 46.2%; p<0.001, and 74.8% versus 68.7%; p = 0.090). Multivariable analysis demonstrated that male sex was independently associated with CAC progression rate among the entire group (p<0.001). Subgroup analyses showed an independent association between male sex and CAC progression rate only in the low-risk group. The CAC progression rate is higher in men than in women. However, the difference between women and men diminishes as the 10-year ASCVD risk increases.

Abstract
BACKGROUND AND OBJECTIVE There is limited evidence on the clinical effects of statins in older persons. We aimed to explore statin use and discontinuation patterns in Danes age 70 and older. DESIGN Register-based drug utilisation study. SETTING Danish nationwide health registries. SUBJECTS All Danish persons aged ≥70 years between 2011 and 2016. MEASUREMENTS (1) Monthly prevalence and (2) quarterly incidence of statin use, (3) characteristics of new users, (4) total amount of statin redeemed, (5) statin discontinuation rate between 2014 and 2016 in long-term statin users and (6) factors associated with discontinuation. RESULTS We identified 395,279 unique older statin users between 2011 and 2016. The prevalence increased from 30% in 2011 to 33% in 2016 (23% for primary prevention and 56% for secondary prevention in 2016). The quarterly incidence fell from 11 per 1,000 persons in 2011 to 7 per 1,000 persons in 2016. The prevalence was generally stable in those 70 to 79 years. In those aged ≥80 years, the prevalence increased despite decreasing incidence. The proportion of persons initiating for primary prevention decreased from 58% in 2011 to 52% in 2016. Approximately 19% of long-term statin users discontinued therapy between 2014 and 2016. Increasing age was the strongest predictor of statin discontinuation. CONCLUSIONS Approximately one in three Danes age ≥ 70 years were taking statins in 2016. The characteristics of incident users shifted between 2011 and 2016, with less people age 80 and older starting on statins and fewer people starting for primary prevention.

Abstract
Ageing is a universal biological phenomenon that is accompanied by the development of chronic, low-grade inflammation and remodelling of the immune system resulting in compromised immune function. In this review, we explore how the trafficking of innate and adaptive immune cells under homeostatic and inflammatory conditions is dysregulated in ageing. We particularly highlight the age-related changes in the expression of adhesion molecules and chemokine receptor/ligands, and the accumulation of senescent cells that drive modulated leukocyte trafficking. These age-related changes to leukocyte trafficking are multifactorial and specific to leukocyte subset, tissue, type of vascular bed, and inflammatory status. However, dysregulated leukocyte trafficking ultimately affects immune responses in older adults. We therefore go on to discuss approved drugs, including anti-integrins, anti-chemokines and statins, as well as novel therapeutics that may be used to target dysregulated leukocyte trafficking in ageing, improve immune responses and delay the onset of age-related diseases.

Abstract
Background and aims The UK Simon Broome (SB) familial hypercholesterolaemia (FH) register previously reported 3-fold higher standardised mortality ratio for cardiovascular disease (CVD) in women compared to men from 2009 to 2015. Here we examined sex differences in CVD morbidity in FH by national linkage of the SB register with Hospital Episode Statistics (HES). Methods Of 3553 FH individuals in the SB register (aged 20–79 years at registration), 2988 (52.5% women) had linked HES records. Standardised Morbidity Ratios (SMbR) compared to an age and sex-matched UK general practice population were calculated [95% confidence intervals] for first CVD hospitalisation in HES (a composite of coronary heart disease (CHD), myocardial infarction (MI), stable or unstable angina, stroke, TIA, peripheral vascular disease (PVD), heart failure, coronary revascularisation interventions). Results At registration, men had significantly (p < 0.001) higher prevalence of previous CHD (24.8% vs 17.6%), previous MI (13.2% vs 6.3%), and were commenced on lipid-lowering treatment at a younger age than women (37.5 years vs 42.3 years). The SMbR for composite CVD was 6.83 (6.33–7.37) in men and 7.55 (6.99–8.15) in women. In individuals aged 30–50 years, SMbR in women was 50% higher than in men (15.04 [12.98–17.42] vs 10.03 [9.01–11.17]). In individuals >50 years, SMbR was 33% higher in women than men (6.11 [5.57–6.70] vs 4.59 [4.08–5.15]). Conclusions Excess CVD morbidity due to FH remains markedly elevated in women at all ages, but especially those aged 30–50 years. This highlights the need for earlier diagnosis and optimisation of lipid-lowering risk factor management for all FH patients, with particular attention to young women with FH. Males with familial hypercholesterolaemia (FH) had more cardiovascular disease (CVD) risk factors and were commenced on lipid-lowering therapy at a younger age, than females with FH. Individuals with FH had excess rates of hospitalisations for CVD, compared to the general population of non-FH individuals. Excess CVD morbidity due to FH was higher in women than men aged 30 years and over, but especially in those aged 30–50 years.

Liu Y, Lv X, Xie N, Fang Z, Ren W, Gong Y, Jin Y, Zhang J. Time trends analysis of statin prescription prevalence, therapy initiation, dose intensity, and utilization from the hospital information system of Jinshan Hospital, Shanghai (2012-2018). BMC Cardiovasc Disord 2020; 20:201. [PMID: 32334525 PMCID: PMC7183656 DOI: 10.1186/s12872-020-01482-5] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2020] [Accepted: 04/12/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Statin remains a mainstay in the prevention and treatment of cardiovascular diseases. Statin utilization has evolved over time in many countries, but data on this topic from China are quite limited. This study aimed to investigate the changing trends of statins prescription, as well as detail the statin utilization through a successive longitudinal study. METHODS The prescription database was established based on electronic health records retrieved from the hospital information system of Jinshan Hospital, Fudan University from January 2012 to December 2018 in Shanghai, China. The prescription rates and proportions of different statin types and doses among all patients were examined. Sub-analyses were performed when stratifying the patients by age, gender, dose intensity, and preventative intervention. RESULTS During the study period, a total of 51,083 patients, who were prescribed for statins, were included in this study (mean [SD] age, 59.78 [±13.16] years; 53.60% male, n = 27, 378). The overall statins prescription rate in which patients increased from 2012 (1.24, 95% CI: 1.21-1.27%) to 2018 (3.16, 95% CI: 3.11-3.20%), P < 0.001. Over 90% of patients were given a moderate dose of statins. Patients with a history of coronary and cerebrovascular events (over 32%) were more likely to be prescribed with statins for preventative intervention. Furthermore, our study has witnessed a significant rise in statin therapy in primary and secondary prevention. CONCLUSIONS In conclusion, statins were frequently prescribed and steadily increased over time in our study period. There were also changes in statin drug choices and dosages. A coordinated effort among the patient, clinical pharmacist, stakeholders and health system is still needed to improve statin utilization in clinical practice in the future.

Abstract
BACKGROUND Excess weight is associated with poor health and increased healthcare costs. There are no reliable data describing the association between BMI and the use and costs of primary care services in the United Kingdom. METHODS Among 69,440 participants in the Million Women Study with primary care records in the Clinical Practice Research Datalink between April 2006 (mean age 64 years) and March 2014, the annual rates and costs of their primary care consultations, prescription medications, and diagnostic and monitoring tests were estimated in relation to their self-reported body mass index (BMI) at recruitment in 1996-2001 (mean age 56 years). Associations of BMI with annual costs were projected to all women in England aged 55-79 years in 2013. RESULTS Over an average follow-up of 6.0 years, annual rates and mean costs were lowest for women with a BMI of 20 to <22.5 kg/m2 for consultations (7.0 consultations, 99% CI 6.8-7.1; £288, £280-£295) and prescription medications (27.0 prescribed items, 26.0-27.9; £227, £216-£237). Above 20 kg/m2, a 2 kg/m2 higher BMI (a 5 kg change in weight for a woman of average height) was associated with 5.2% (4.8-5.6) and 9.9% (9.2-10.6) higher mean annual consultation and prescription medication costs, respectively. Annual rates and mean costs of diagnostic and monitoring tests were similar for women with different BMIs. Among all women aged 55-79 years in England, excess weight accounted for an estimated 11% (£229 million/£2.2 billion) of all consultation costs and 20% (£384 million/£1.9 billion) of all prescription medication costs, of which 27% were for diabetes drugs, 19% for circulatory system drugs, and 13% for analgesics. CONCLUSIONS Excess body weight is associated with higher use and costs of primary care services among women in England. Reducing the prevalence of excess weight could improve the health of women and reduce pressures on primary care.

Abstract
BACKGROUND Cardiovascular guidelines do not give firm recommendations on statin therapy in patients with gout because evidence is lacking. AIM To analyze the effectiveness of statin therapy in primary prevention of coronary heart disease (CHD), ischemic stroke (IS), and all-cause mortality in a population with gout. METHODS A retrospective cohort study (July 2006 to December 2017) based on Information System for the Development of Research in Primary Care (SIDIAPQ), a research-quality database of electronic medical records, included primary care patients (aged 35-85 years) without previous cardiovascular disease (CVD). Participants were categorized as nonusers or new users of statins (defined as receiving statins for the first time during the study period). Index date was first statin invoicing for new users and randomly assigned to nonusers. The groups were compared for the incidence of CHD, IS, and all-cause mortality, using Cox proportional hazards modeling adjusted for propensity score. RESULTS Between July 2006 and December 2008, 8018 individuals were included; 736 (9.1%) were new users of statins. Median follow-up was 9.8 years. Crude incidence of CHD was 8.16 (95% confidence interval [CI]: 6.25-10.65) and 6.56 (95% CI: 5.85-7.36) events per 1000 person-years in new users and nonusers, respectively. Hazard ratios were 0.84 (95% CI: 0.60-1.19) for CHD, 0.68 (0.44-1.05) for IS, and 0.87 (0.67-1.12) for all-cause mortality. Hazard for diabetes was 1.27 (0.99-1.63). CONCLUSIONS Statin therapy was not associated with a clinically significant decrease in CHD. Despite higher risk of CVD in gout populations compared to general population, patients with gout from a primary prevention population with a low-to-intermediate incidence of CHD should be evaluated according to their cardiovascular risk assessment, lifestyle recommendations, and preferences, in line with recent European League Against Rheumatism recommendations.

Abstract
Background Ischemic heart disease (IHD) has been considered the top cause of mortality globally. However, countries differ in their rates and there have been changes over time. Methods and Results We analyzed mortality data submitted to the World Health Organization from 2005 to 2015 by individual countries. We explored patterns in relationships with age, sex, and income and calculated age-standardized mortality rates for each country in addition to crude death rates. In 5 illustrative countries which provided detailed data, we analyzed trends of mortality from IHD and 3 noncommunicable diseases (lung cancer, stroke, and chronic lower respiratory tract diseases) and examined the simultaneous trends in important cardiovascular risk factors. Russia, United States, and Ukraine had the largest absolute numbers of deaths among the countries that provided data. Among 5 illustrative countries (United Kingdom, United States, Brazil, Kazakhstan, and Ukraine), IHD was the top cause of death, but mortality from IHD has progressively decreased from 2005 to 2015. Age-standardized IHD mortality rates per 100 000 people per year were much higher in Ukraine (324) and Kazakhstan (97) than in United States (60), Brazil (54), and the United Kingdom (46), with much less difference in other causes of death. All 5 countries showed a progressive decline in IHD mortality, with a decline in smoking and hypertension and in all cases a rise in obesity and type II diabetes mellitus. Conclusions IHD remains the single largest cause of death in countries of all income groups. Rates are different between countries and are falling in most countries, indicating great potential for further gains. On the horizon, future improvements may become curtailed by increasing hypertension in some developing countries and more importantly global growth in obesity.

Abstract
OBJECTIVES The benefits of initiating statins in the elderly remains debated. We evaluated the effects of initiating statins in the elderly, according to cardiovascular risk. METHODS This population-based cohort study used data of the representative sample of the French health care system database for the 2008-2015 period. New users of statins, aged 75 years and older, were dynamically included in the cohort and matched 1:1 to statin nonusers on age, sex, numbers of different drugs dispensed and medical consultations, and cardiovascular history. Patients were classified into 3 cardiovascular risk groups: secondary prevention (history of coronary heart disease), primary prevention with modifiable risk factors (diabetes or cardiovascular medications), and primary prevention without modifiable risk factors (none of the above). Effect of cumulative use of statins on occurrence of acute coronary syndrome or all-cause death was analyzed by using multivariable time-dependent Cox models stratified on cardiovascular risk at inclusion. RESULTS Among the 7284 patients included, median follow-up was 4.7 years. Cumulative use of statins was associated with a lower risk of outcomes in the primary prevention with modifiable risk factors group (adjusted hazard ratio 0.93 per year of use; 95% confidence interval, 0.89-0.96; P < .01) and in the secondary prevention group (0.75; 0.63-0.90; P < .01), but not in the primary prevention without modifiable risk factors group (1.01; 0.86-1.18; P = .92). CONCLUSIONS Statin treatment was not associated with a reduction in acute coronary syndrome or all-cause death in elderly without modifiable cardiovascular risk factor treated in primary prevention.

Abstract
The present paper reviews the evidence as to whether patients on lipid-lowering drugs should restrict dietary SFA intake. Premature mortality from atherosclerotic CVD has fallen dramatically in many high-income countries. This appears to be due to a combination of improved treatment following a cardiovascular event and reduced risk factors, including LDL-cholesterol. Whether this reduction is due to changes in dietary habits, or the increasing availability of highly potent cholesterol-reducing drugs remains to be firmly established. While reducing dietary SFA intake has been the cornerstone of public health nutrition policy for several decades, the efficacy of such dietary changes has been challenged in recent years. While there remains a lack of consensus in the literature, there is an emerging view that dietary advice should be specifically modified to emphasise replacing SFA with PUFA in the diet rather than carbohydrate. The advice to moderate dietary SFA intake given to the general population is usually also given to those individuals at high risk of CVD who are prescribed lipid-lowering drugs. There is limited evidence to suggest that any potential benefit of such a diet on LDL-cholesterol may be offset by a concurrent decrease in HDL-cholesterol. However, as diets rich in SFA are frequently energy-dense, and rich in red and processed meat (potential risk factors for CVD in themselves), it would seem prudent to continue to advise patients on lipid-lowering drugs to maintain a low-fat diet.

Abstract
OBJECTIVE This study analysed utilisation of statins for new statin users and assessed market dynamics of statins in South Korea. DESIGN This study is a retrospective cohort study. SETTING The yearly claims data for statins were retrieved from the National Health Insurance Service-National Sample Cohort. MAIN OUTCOME MEASURE We are interested in new statin users during 2003-2015 in Korea. Information on prescribed statins, including intensity of statins and entry of new and follow-on statins in the market, and healthcare institutions that prescribed the statins were also collected. In time series analysis, we estimated the effect of introduction of generics in the market, specifically for newly prescribed statin users. RESULTS This 13-year longitudinal study of a sample cohort provided by the National Health Insurance Service found that the incidence of new statin user increase from 838.1/100 000 persons in 2003 to 1626.9/100 000 persons in 2015. Most new users were initiated on a monotherapy that was prescribed at primary healthcare institutions. However, the statin market for new users were quite dynamic in Korea. First, the most commonly prescribed statin changed several times during the study period. Second, the use of moderate-intensity statins increased from 57% in 2003 to 92% in 2015. In line with this result, we could not observe substantial differences in prescription of statins in groups having selected diseases history. Lastly, we found market invasion or switch of statins among new statin users, specifically at primary healthcare institutions. CONCLUSION Similar to other countries, the incidence of new statin users has been increased in Korea. However, the statin market in Korea is quite dynamic compared with other countries. Interestingly, discounted price of originals after the introduction of generics immediately expand markets or substitute the market particularly in primary healthcare institutions in Korea.

Abstract
Background Clinical databases are increasingly used for health research; many of them capture information on common health indicators including height, weight, blood pressure, cholesterol level, smoking status, and alcohol consumption. However, these are often not recorded on a regular basis; missing data are ubiquitous. We described the recording of health indicators in UK primary care and evaluated key implications for handling missing data. Methods We examined the recording of health indicators in The Health Improvement Network (THIN) UK primary care database over time, by demographic variables (age and sex) and chronic diseases (diabetes, myocardial infarction, and stroke). Using weight as an example, we fitted linear and logistic regression models to examine the associations of weight measurements and the probability of having weight recorded with individuals’ demographic characteristics and chronic diseases. Results In total, 6,345,851 individuals aged 18–99 years contributed data to THIN between 2000 and 2015. Women aged 18–65 years were more likely than men of the same age to have health indicators recorded; this gap narrowed after age 65. About 60–80% of individuals had their height, weight, blood pressure, smoking status, and alcohol consumption recorded during the first year of registration. In the years following registration, these proportions fell to 10%–40%. Individuals with chronic diseases were more likely to have health indicators recorded, particularly after the introduction of a General Practitioner incentive scheme. Individuals’ demographic characteristics and chronic diseases were associated with both observed weight measurements and missingness in weight. Conclusion Missing data in common health indicators will affect statistical analysis in health research studies. A single analysis of primary care data using the available information alone may be misleading. Multiple imputation of missing values accounting for demographic characteristics and disease status is recommended but should be considered and implemented carefully. Sensitivity analysis exploring alternative assumptions for missing data should also be evaluated.

Abstract
INTRODUCTION Two previous meta-analyses evaluated the risk of cataracts associated with statins, but did not include relevant studies suggesting a cataractogenic effect. AIMS The aim of this systematic review and meta-analysis of observational studies is to evaluate such association considering the latest published evidence. METHODS A literature search was conducted to identify observational, comparative studies evaluating the risk of developing cataracts in patients treated with statins. A meta-analysis was performed to estimate odds ratios (ORs). Results were stratified according to the following studies' subgroups: design, methodological quality, method of diagnosis of cataract, patients' age, and median follow-up. Meta-regressions evaluated the influence of the following risk factors: smoking, hypertension, corticosteroids, selective serotonin reuptake inhibitors (SSRI), diabetes mellitus, and cardiovascular disease. RESULTS Twenty-one studies were included. Treatment with statins was associated with an increased risk of cataracts [OR: 1.11 (95% CI: 1.02-1.21); P = 0.017; I2 = 97.5%]. This risk remained statistically significant among case-controls, good methodological quality studies, studies with length of follow-up ≥5 years and those which outcome was cataract surgery. Between-studies heterogeneity was high among all risk estimates. Meta-regressions identified an inverse relationship between the risk of cataracts and the proportion of diabetic patients in the studies. CONCLUSIONS The results point out an increased risk of cataract development with statins. However, since the magnitude of the effect is low and between-studies heterogeneity is high, the extent in which these results have impact on the benefit/risk ratio of statins is difficult to ascertain due to the uncertainty of the findings.

Abstract
The evaluation of the real-life benefits and risks of statins in population is a major pharmacoepidemiological issue, given their widespread use for cardiovascular prevention. The purpose of this review was not to be exhaustive but to show the contributions of pharmacoepidemiology for various aspects of the evaluation of statins such as real-life drug use, effectiveness and risk. Statins are among the most used drugs in the world, but recent data show a slight decrease in use. Actual statin users are older, and have more comorbidities than those studied in clinical trials, but this does not seem to compromise their effectiveness, unlike the compliance issues that are common with these drugs. Beyond the known adverse reactions of statins from the clinical trials, risks of statins can be varied and sometimes difficult to evaluate, considering the ubiquity of cholesterol throughout the body, from drug or endogenous molecule metabolism to the construction of cell membranes or cell activities.

Abstract
Background and aims The International Atherosclerosis Society (IAS) has proposed that patients with “severe” FH (SFH) would warrant early and more aggressive cholesterol-lowering treatment such as with PCSK9 inhibitors. SFH is diagnosed if LDL-cholesterol (LDLC) > 10 mmol/L, or LDLC >8.0 mmol/L plus one high-risk feature, or LDLC >5 mmol/L plus two high-risk features. Here we compare CHD mortality in SFH and non-SFH (NSFH) patients in the UK prospective Simon Broome Register since 1991, when statin use became routine. Methods 2929 definite or possible PFH patients (51% women) aged 20–79 years were recruited from 21 UK lipid clinics and followed prospectively between 1992 and 2016. The excess CHD standardised mortality ratio (SMR) compared to the England and Wales population was calculated (with 95% confidence intervals). Results 1982 (67.7%) patients met the SFH definition. Compared to the non-SFH, significantly (p < 0.001) more SFH patients had diagnosed CHD at baseline (24.6% vs. 17.5%), were current smokers (21.9% vs 10.2%) and had a BMI > 30 kg/m2 (14.9% vs. 7.8%). The SMR for CHD mortality was significantly (p = 0.007) higher for SFH (220 (184–261) (34,134 person years, 129 deaths observed, vs. 59 expected) compared to NSFH of 144 (98–203) (15,432 person years, 32 observed vs. 22 expected). After adjustment for traditional risk factors, the Hazard Ratio for CHD mortality in SFH vs. NSFH was 1.22 (0.80–1.87) p = 0.36, indicating that the excess risk was largely accounted for by these factors. Conclusions CHD mortality remains elevated in treated FH, especially for SFH, emphasising the importance of optimal lipid-lowering and management of other risk factors. Patients with IAS-defined “severe” FH (SFH) are at highest risk of future CHD. In the UK Simon Broome FH Register ∼70% meet the SFH criteria. Those with SFH have 64% higher CHD mortality than non SFH patients. This is explained by their higher classical risk factors including untreated LDL-C.

Abstract
Herpes zoster (HZ), which is caused by reactivation of latent varicella zoster virus (VZV), constitutes a major public health concern in both short- and long-term periods. Over the last years, several epidemiological studies have demonstrated that statin use is associated with increased risk of HZ at cerebral level. Because statins are among the most popular and best-selling drugs in western countries, this potential negative pleiotropic effect could have important implications in the daily clinical practice. In the present manuscript, we reviewed the available data on the statin use and the relative risk of HZ infection.

Abstract
INTRODUCTION AND OBJECTIVES Statins have become an integral part of treatment to reduce cardiac events in patients with cardiovascular disease. However, their use within the public healthcare system in Brazil is unknown. Consequently, we sought to determine and characterize statin use in primary healthcare delivered by the public health system (SUS) in Brazil and evaluate associated patient factors to improve future use. METHODS Cross-sectional study with a national representative sample from five Brazilian regions, derived from the National Survey on Access, Use and Promotion of Rational Use of Medicines using a multi-stage complex sampling plan. Patients over 18 years old were interviewed from July 2014 to May 2015. The prevalences of statin use and self-reported statin adherence were determined amongst medicine users. The associations between statin use and sociodemographic/health condition variables were assessed using logistic regression. RESULTS A total of 8803 patients were interviewed, of whom 6511 were medicine users. The prevalence of statin use was 9.4% with simvastatin (90.3%), atorvastatin (4.7%) and rosuvastatin (1.9%) being the most used statins. Poor adherence was described by 6.5% of patients. Statin use was significantly associated with age ≥65 years old, higher educational level, residence in the South, metabolic and heart diseases, alcohol consumption and polypharmacy. CONCLUSIONS This is the first population based study in Brazil to assess statin use in SUS primary healthcare patients. Addressing inequalities in access and use of medicines including statins is an important step in achieving the full benefit of statins in Brazil, with the findings guiding future research and policies.

Abstract
OBJECTIVE To assess whether statin treatment is associated with a reduction in atherosclerotic cardiovascular disease (CVD) and mortality in old and very old adults with and without diabetes. DESIGN Retrospective cohort study. SETTING Database of the Catalan primary care system (SIDIAP), Spain, 2006-15. PARTICIPANTS 46 864 people aged 75 years or more without clinically recognised atherosclerotic CVD. Participants were stratified by presence of type 2 diabetes mellitus and as statin non-users or new users. MAIN OUTCOME MEASURES Incidences of atherosclerotic CVD and all cause mortality compared using Cox proportional hazards modelling, adjusted by the propensity score of statin treatment. The relation of age with the effect of statins was assessed using both a categorical approach, stratifying the analysis by old (75-84 years) and very old (≥85 years) age groups, and a continuous analysis, using an additive Cox proportional hazard model. RESULTS The cohort included 46 864 participants (mean age 77 years; 63% women; median follow-up 5.6 years). In participants without diabetes, the hazard ratios for statin use in 75-84 year olds were 0.94 (95% confidence interval 0.86 to 1.04) for atherosclerotic CVD and 0.98 (0.91 to 1.05) for all cause mortality, and in those aged 85 and older were 0.93 (0.82 to 1.06) and 0.97 (0.90 to 1.05), respectively. In participants with diabetes, the hazard ratio of statin use in 75-84 year olds was 0.76 (0.65 to 0.89) for atherosclerotic CVD and 0.84 (0.75 to 0.94) for all cause mortality, and in those aged 85 and older were 0.82 (0.53 to 1.26) and 1.05 (0.86 to 1.28), respectively. Similarly, effect analysis of age in a continuous scale, using splines, corroborated the lack of beneficial statins effect for atherosclerotic CVD and all cause mortality in participants without diabetes older than 74 years. In participants with diabetes, statins showed a protective effect against atherosclerotic CVD and all cause mortality; this effect was substantially reduced beyond the age of 85 years and disappeared in nonagenarians. CONCLUSIONS In participants older than 74 years without type 2 diabetes, statin treatment was not associated with a reduction in atherosclerotic CVD or in all cause mortality, even when the incidence of atherosclerotic CVD was statistically significantly higher than the risk thresholds proposed for statin use. In the presence of diabetes, statin use was statistically significantly associated with reductions in the incidence of atherosclerotic CVD and in all cause mortality. This effect decreased after age 85 years and disappeared in nonagenarians.

Abstract
BACKGROUND AND AIMS Patients with familial hypercholesterolaemia (FH) have an elevated risk of coronary heart disease (CHD). Here we compare changes in CHD mortality in patients with heterozygous (FH) pre 1992, before lipid-lowering therapy with statins was used routinely, and in the periods 1992-2008 and 2008-2016. METHODS 1903 Definite (DFH) and 1650 Possible (PFH) patients (51% women) aged 20-79 years, recruited from 21 lipid clinics in the United Kingdom and followed prospectively between 1980 and 2016 for 67,060 person-years. The CHD standardised mortality ratio (SMR) compared to the population in England and Wales was calculated (with 95% Confidence intervals). RESULTS There were 585 deaths, including 252 from CHD. Overall, the observed 2.4-fold excess coronary mortality for treated DFH post-1991 was significantly higher than the 1.78 excess for PFH (35% 95% CI 3%-76%). In patients with DFH and established coronary disease, there was a significant excess coronary mortality in all time periods, but in men it was reduced from a 4.83-fold excess (2.32-8.89) pre-1992 to 4.66 (3.46-6.14) in 1992-2008 and 2.51 (1.01-5.17) post-2008, while in women the corresponding values were 7.23 (2.65-15.73), 4.42 (2.70-6.82) and 6.34 (2.06-14.81). Primary prevention in men with DFH resulted in a progressive reduction in coronary mortality over the three time-periods, with no excess mortality evident post-2008 (0.89 (0.29-2.08)), although in women the excess persisted (post-2008 3.65 (1.75-6.72)). CONCLUSIONS The results confirm the benefit of statin treatment in reducing CHD mortality, but suggest that FH patients with pre-existing CHD and women with FH may not be treated adequately.

Abstract
BACKGROUND The extent to which outcome benefits may be achieved through the implementation of aggressive low-density lipoprotein (LDL) cholesterol targets in real world settings remains unknown, especially among elderly statin users following acute coronary syndromes. METHODS AND RESULTS A population-based cohort study consisting of 19 544 post-acute coronary syndrome statin-users aged ≥66 years between January 1, 2017 and March 31, 2014 was used to project the number of adverse outcome events (acute myocardial infarction or death from any cause) that could be prevented if all post-acute coronary syndrome elderly statin users were treated to 1 of 2 LDL cholesterol target levels (≤50 and ≤70 mg/dL). The number of preventable adverse outcomes was estimated by using model-based expected event probabilities as derived from Cox Proportional hazards models. In total, 61.6% and 25.5% of the elderly patients met LDL cholesterol targets of ≤70 and ≤50 mg/dL, respectively, based on current management. No more than 2.3 adverse events per 1000 elderly statin users (95% confidence interval: -0.7 to 5.4, P=0.62) could be prevented over 8.1 years if all patients were to be treated from current LDL cholesterol levels to either of the 2 LDL cholesterol targets of 70 or 50 mg/dL. CONCLUSIONS The number of acute myocardial infarctions or death that could be prevented through the implementation of LDL cholesterol targets with statins is negligible among an elderly post-acute coronary syndrome population. Such findings may have implications for the applicability of newer agents, such as proprotein convertase subtilisin/kexin type-9- inhibitors.

[PMID: 29501869 DOI: 10.1016/j.ejphar.2018.02.050] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2017] [Revised: 02/27/2018] [Accepted: 02/28/2018] [Indexed: 12/22/2022]
Abstract
Statins are effective in management of dyslipidaemia, and a cornerstone of CVD prevention strategies. However, the impacts of their pleiotropic effects on other cardiovascular risk factors and myocardial responses to infarction are not well characterised. We hypothesised that pravastatin treatment in obesity improves lipid profiles, insulin-resistance and myocardial resistance to ischaemia/reperfusion (I/R) injury. Wistar rats were fed a control (C) chow or high carbohydrate and fat diet (HCFD) for 16 weeks with vehicle or pravastatin (prava 7.5 mg/kg/day) treatment for 8 weeks. At 16 weeks HOMAs were performed, blood samples collected and hearts excised for Langendorff perfusions/biochemical analyses. Anti-oxidant activity and proteins regulating mitochondrial fission/fusion and apoptosis were assessed. The HCFD increased body weight (736±15 vs. 655±12 g for C; P<0.001), serum triglycerides (2.91±0.52 vs. 1.64±0.26 mmol/L for C; P<0.001) and insulin-resistance (HOMA- 6.9±0.8 vs. 4.2±0.5 for C; P<0.05) while prava prevented diet induced changes and paradoxically increased lipid peroxidation. The HCFD increased infarct size (34.1±3.1% vs. 18.8±3.0% of AAR for C; P<0.05), which was unchanged by prava in C and HCFD animals. The HCFD decreased cardiac TxR activity and mitochondrial MFN-1 and increased mitochondrial DRP-1 (reducing MFN-1:DRP-1 ratio) and Bax expression, with the latter changes prevented by prava. While unaltered by diet, cytosolic levels of Bax and caspase-3 were reduced by prava in C and HCFD hearts (without changes in cleaved caspase-3). We conclude that obesity, hyper-triglyceridemia and impaired glycemic control in HCFD rats are countered by prava. Despite improved risk factors, prava did not reduce myocardial infarct size, potentially reflecting its complex pleiotropic impacts on cardiac GPX activity and MFN-1, DRP-1, caspase-3 and Bcl-2 proteins.

Schizophr Res 2018; 192:219-225. [PMID: 28599749 DOI: 10.1016/j.schres.2017.05.028] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2017] [Revised: 05/17/2017] [Accepted: 05/24/2017] [Indexed: 12/20/2022]
Abstract
BACKGROUND Severe mental illness (SMI) is associated with excess cardiovascular disease (CVD) morbidity, but little is known on provision of preventative interventions. We investigated statin initiation for primary CVD prevention in individuals with and without SMI. METHODS We used primary care data from The Health Improvement Network from 2006 to 2015 for UK patients aged 30-99years with no pre-existing CVD conditions and selected individuals with schizophrenia (n=13,252) or bipolar disorder (n=11,994). In addition, we identified samples of individuals without schizophrenia (n=66,060) and bipolar disorder (n=59,765), but with similar age and gender distribution. Missing data on CVD covariates were estimated using multiple imputation. Statin prescribing differences between individuals with and without SMI were investigated using multivariable Poisson regression models. RESULTS Initiation of statin prescribing was between 2 and 3 fold higher in people aged 30-59years with SMI than in those without after adjusting for CVD covariates. The rates in those aged 60-74years with SMI were similar or slightly higher relative to those without SMI. The incidence rate ratio (IRR) was 1.15 (95% CI 1.03-1.28) for bipolar disorder and 1.00 (0.91-1.11) for schizophrenia. The rate of statin prescribing was lower (IRR 0.81 (0.66-0.98)) amongst the oldest (aged 75+years) with schizophrenia relative to those without schizophrenia. CONCLUSIONS Despite higher rates of new statin prescriptions to younger individuals with SMI relative to individuals without SMI, there was evidence of lower rates of statin initiation for older individuals with schizophrenia, and this group may benefit from additional measures to prevent CVD.

Abstract
BACKGROUND Statin prescribing should be based on cardiovascular disease (CVD) risk, but evidence suggests overtreatment of low-risk groups and undertreatment of high-risk groups. AIM To investigate the relationship between CVD risk scoring in primary care and initiation of statins for the primary prevention of CVD, and the effect of changes to the National Institute for Health and Care Excellence (NICE) guidance in 2014. DESIGN AND SETTING Historical cohort study using UK electronic primary care records. METHOD A cohort was created of statin-naïve patients without CVD between 1 January 2000 and 31 December 2015. CVD risk scores (calculated using QRISK2 available from 2012) and statin initiations were identified. Rates of CVD risk score recording were calculated and relationships between CVD risk category (low-, intermediate-, and high-risk: <10%, 10-19.9%, and ≥20% 10-year CVD risk) and statin initiation were analysed. RESULTS A total of 1.4 million patients were identified from 248 practices. Of these, 151 788 had a recorded CVD risk score since 2012 (10.67%) and 217 860 were initiated on a statin (15.31%). Among patients initiated on a statin after 2012, 27.1% had a documented QRISK2 score: 2.7% of low-risk, 13.8% of intermediate-risk, and 35.0% of high-risk patients were initiated on statins. Statin initiation rates halved from a peak in 2006. After the 2014 NICE guidelines, statin initiation rates declined in high-risk patients but increased in intermediate-risk patients. CONCLUSION Most patients initiated on statins had no QRISK2 score recorded. Most patients at high risk of CVD were not initiated on statins. One in six statin initiations were to low-risk patients indicating significant overtreatment. Initiations of statins in intermediate-risk patients rose after NICE guidelines were updated in 2014.

Abstract
INTRODUCTION Drug-drug interactions (DDIs) continue to account for 5% of hospital admissions and therefore remain a major regulatory concern. Effective, quantitative prediction of DDIs will reduce unexpected clinical findings and encourage projects to frontload DDI investigations rather than concentrating on risk management ('manage the baggage') later in drug development. A key challenge in DDI prediction is the discrepancies between reported models. Areas covered: The current synopsis focuses on four recent influential publications on hepatic drug transporter DDIs using static models that tackle interactions with individual transporters and in combination with other drug transporters and metabolising enzymes. These models vary in their assumptions (including input parameters), transparency, reproducibility and complexity. In this review, these facets are compared and contrasted with recommendations made as to their application. Expert opinion: Over the past decade, static models have evolved from simple [I]/ki models to incorporate victim and perpetrator disposition mechanisms including the absorption rate constant, the fraction of the drug metabolised/eliminated and/or clearance concepts. Nonetheless, models that comprise additional parameters and complexity do not necessarily out-perform simpler models with fewer inputs. Further, consideration of the property space to exploit some drug target classes has also highlighted the fine balance required between frontloading and back-loading studies to design out or 'manage the baggage'.

Abstract
BACKGROUND To assess the current landscape of the heart failure (HF) epidemic and provide targets for future health policy interventions in Medicare, a contemporary appraisal of its epidemiology across inpatient and outpatient care settings is needed. METHODS AND RESULTS In a national 5% sample of Medicare beneficiaries from 2002 to 2013, we identified a cohort of 2 331 939 unique fee-for-service Medicare beneficiaries ≥65-years-old followed for all inpatient and outpatient encounters over a 10-year period (2004-2013). Preexisting HF was defined by any HF encounter during the first year, and incident HF with either 1 inpatient or 2 outpatient HF encounters. Mean age of the cohort was 72 years; 57% were women, and 86% and 8% were white and black, respectively. Within this cohort, 518 223 patients had preexisting HF, and 349 826 had a new diagnosis of HF during the study period. During 2004 to 2013, the rates of incident HF declined 32%, from 38.7 per 1000 (2004) to 26.2 per 1000 beneficiaries (2013). In contrast, prevalent (preexisting + incident) HF increased during our study period from 162 per 1000 (2004) to 172 per 1000 beneficiaries (2013) (Ptrend <0.001 for both). Finally, the overall 1-year mortality among patients with incident HF is high (24.7%) with a 0.4% absolute decline annually during the study period, with a more pronounced decrease among those diagnosed in an inpatient versus outpatient setting (Pinteraction <0.001) CONCLUSIONS: In recent years, there have been substantial changes in the epidemiology of HF in Medicare beneficiaries, with a decline in incident HF and a decrease in 1-year HF mortality, whereas the overall burden of HF continues to increase.

Abstract
Objective statin use over the age of 80 years is weakly evidence-based. This study aimed to estimate rates of statin inception and deprescribing by frailty level in people aged 80 years or older. Methods a cohort of 212,566 participants aged ≥80 years was sampled from the UK Clinical Practice Research Datalink. Statin inception was defined as a first-ever prescription in a non-statin user; deprescribing was defined as a last ever statin prescription more than 6 months before the end of participant records. Rates were estimated in a time-to-event framework allowing for mortality as a competing risk. Co-variates were age, gender, frailty category and prevention type. Results prevalent statin use increased from 2001-5 (9.9%) to 2011-15 (49.3%). Inception of statins in never-users was low overall at 2.4% per year (95% confidence interval (CI) 2.2-2.6%) and declined with age. Deprescribing of statins in current users occurred at a rate of 5.6% (95% CI 5.4-5.9%) per year overall and increased with age, reaching 17.8% per year (95% CI 6.7-28.9%) among centenarians. Deprescribing was slightly higher for primary prevention (6.5% per year) than secondary prevention (5.2% per year) indications (P < 0.001). Deprescribing increased with frailty level being 5.0% per year in 'fit' participants and 7.1% in 'severe' frailty (P < 0.001). Conclusions statin use has increased in the over 80s but deprescribing is common and increases with age and frailty level. These paradoxical findings highlight a need for better evidence to inform statin use and discontinuation for people aged ≥80 years.
