Background: The risk-benefit balance of statin use in healthy older people is uncertain. We describe the baseline characteristics of the STAREE (Statins in Reducing Events in the Elderly) trial, which is a randomized, double-blind, placebo-controlled trial among community-dwelling older people; the trial evaluated the effect of atorvastatin 40 mg for the prevention of major cardiovascular events (cardiovascular death, nonfatal myocardial infarction or stroke), and on disability-free survival (survival free of both dementia and persistent physical disability).

Methods And Results: STAREE enrolled people aged ≥70 years from 1583 general practices across Australia with no history of clinical cardiovascular disease, diabetes, or dementia.

Background: The prognostic implication of cholesterol levels in older adults remains uncertain. This study aimed to examine the relationship between low-density-lipoprotein cholesterol (LDL-c) and mortality outcomes in older individuals.

Methods: This post hoc analysis examined the associations of LDL-c levels with mortality risks from all-cause, cardiovascular disease (CVD), cancer, and combined non-CVD/noncancer conditions in a cohort of individuals aged ≥65 years from the ASPirin in Reducing Events in the Elderly trial (NCT01038583).

Background: Statins are well-established for their treatment of cardiovascular disease (CVD) due to their cholesterol-lowering effects and potential anti-inflammatory properties. Although previous systematic reviews demonstrate that statins reduce inflammatory biomarkers in the secondary prevention of CVD, none examine their effects on cardiac and inflammatory biomarkers in a primary prevention setting.

Methods: We conducted a systematic review and meta-analysis to examine the effects of statins on cardiovascular and inflammatory biomarkers among individuals without established CVD.

Introduction: The world is undergoing a demographic transition to an older population. Preventive healthcare has reduced the burden of chronic illness at younger ages but there is limited evidence that these advances can improve health at older ages. Statins are one class of drug with the potential to prevent or delay the onset of several causes of incapacity in older age, particularly major cardiovascular disease (CVD).

Objective: To determine the association of plasma lipids with the prevalence of subclinical atherosclerosis and 10-year risk of incident cardiovascular (CV) events among healthy individuals without dyslipidemia and with low risk factor burden.

Patients And Methods: The analysis (June 24, 2020, through June 12, 2021) included 1204 participants from the Multi-Ethnic Study of Atherosclerosis (MESA) study who were current nonsmokers and did not have CV disease, hypertension (blood pressure ≥130/80 mm Hg or antihypertensive use), diabetes (fasting glucose ≥126 mg/dL or glucose-lowering medication use), and dyslipidemia (low-density-lipoprotein-cholesterol [LDL-C] ≥160 mg/dL, high-density-lipoprotein-cholesterol [HDL-C] <40 mg/dL, total cholesterol [TC] ≥240 mg/dL, triglycerides [TGs] ≥150 mg/dL, or lipid-lowering medication use) at baseline. Associations of lipids with baseline atherosclerosis (presence of carotid plaque and/or coronary calcification) and incident CV events over 10 years were examined using multivariable relative risk regression and Cox regression, respectively.

Background: Antihypertensives and lipid-lowering therapy (LLT) are often used concurrently.

Objectives: To determine whether there was a difference in clinical outcomes when older patients with LLT were prescribed angiotensin-converting-enzyme-inhibitors (ACE-Is) compared with diuretics.

Methods: This analysis included 648 LLT older users free of cardiovascular disease (CVD) from a trial comparing ACE-I versus diuretic-based therapy.

Purpose: Recent epidemiological evidence has suggested that use of lipid-lowering medications, particularly statins, was associated with reduced cardiovascular disease (CVD) events and persistent physical disability in healthy older adults. However, the comparative efficacy of different statins in this group remains unclear. This study aimed to compare different forms of statins in their associations with CVD and physical disability in healthy older adults.

Background: The neurocognitive effect of statins in older adults remain uncertain.

Objectives: The aim of this study was to investigate the associations of statin use with cognitive decline and incident dementia among older adults.

Methods: This analysis included 18,846 participants ≥65 years of age in a randomized trial of aspirin, who had no prior cardiovascular events, major physical disability, or dementia initially and were followed for 4.

Purpose: Study drug discontinuation is commonplace in clinical trials of older populations. Little is known about why older participants discontinue the study drug. This qualitative study aimed to understand factors contributing to permanent study drug discontinuation among participants aged ≥ 70 years within an ongoing primary prevention trial of statins by exploring their experiences and perceptions.

Aims/hypothesis: Few studies examine the association between age at diagnosis and subsequent complications from type 2 diabetes. This paper aims to summarise the risk of mortality, macrovascular complications and microvascular complications associated with age at diagnosis of type 2 diabetes.

Methods: Data were sourced from MEDLINE and All EBM (Evidence Based Medicine) databases from inception to July 2018.

Background: There is clinical uncertainty regarding the benefits and harms of prescribing statins in healthy subjects ≥70 years of age.

Objectives: The aim of this study was to examine the association among statins, dementia-free and disability-free survival, and cardiovascular disease (CVD) among healthy older adults using data from the ASPREE (Aspirin in Reducing Events in the Elderly) trial.

Methods: ASPREE was a randomized trial of 19,114 community-dwelling persons in Australia and the United States ≥65 years of age and free of documented CVD, dementia, and disability.

The aim of this study was to assess the relative validity and reproducibility of a six-item Australian Short Dietary Screener (Aus-SDS). The Aus-SDS assessed the daily intake of core food groups (vegetables, fruits, legumes and beans, cereals, protein sources and dairy sources) in 100 Australians (52 males and 48 females) aged ≥70 years. Relative validity was assessed by comparing intakes from the Aus-SDS1 with an average of three 24-hour recalls (24-HRs), and reproducibility using two administrations of the Aus-SDS (Aus-SDS1 and Aus-SDS2).

Purpose: The use of statins in the primary prevention of cardiovascular disease (CVD) is increasing in older adults. Nonetheless, good clinical evidence for the safety and tolerability of statins in this population is limited.

Objective: We aimed to evaluate the safety and tolerability of statins in older adults without overt CVD, focusing on statin-related muscle symptoms.

Lipid-lowering therapy (LLT) should be accompanied by dietary guidance for cardiovascular risk reduction; however, current evidence suggests sub-optimal dietary behaviors in those on LLT. We examined the associations between the dietary intake of key food groups (vegetables, fruit, cereal, protein, and dairy) and LLT use in Australian adults using quantile regression. We used data from the Australian Diabetes, Obesity and Lifestyle Study (AusDiab), a prospective population-based study of adults aged ≥25 years, conducted over 5 years (1999-2005).

This review examines the effects of statins on physical activity and/or fitness, as statins can have adverse muscle effects. A search was done of MEDLINE, Embase, and EBMR databases up to July 2018 for randomized controlled trials comparing statin with placebo or control, measuring physical activity and/or fitness in adults. Sixteen randomized controlled trials (total participants [] = 2,944) were included, 6 randomized controlled trials contributed data for meta-analysis.
