Amelioration of gait and balance disorders by rosuvastatin is associated with changes in cerebrovascular reactivity in older patients with hypertensive treatment. Hypertens Res 2024:10.1038/s41440-024-01720-9. [PMID: 38769134 DOI: 10.1038/s41440-024-01720-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2023] [Revised: 04/19/2024] [Accepted: 04/22/2024] [Indexed: 05/22/2024]
Abstract
To investigate the effect of rosuvastatin on gait and balance disorder progression and elucidate the role of cerebrovascular reactivity (CVR) on this effect. From April 2008 to November 2010, 943 hypertensive patients aged ≥60 years were enrolled from the Shandong area of China. Patients were randomized into rosuvastatin and placebo groups. Gait, balance, CVR, fall and stroke were assessed. During an average 72 months of follow-up, the decreasing trends for step length, step speed, and Berg balance scale scores and the increasing trends for step width and chair rising test were slower in the rosuvastatin group when compared to the placebo group. The hazard ratio of incident balance impairment and falls was 0.542 [95% confidence interval (CI) 0.442-0.663] and 0.532 (95% CI 0.408-0.694), respectively, in the rosuvastatin group compared with placebo group. For CVR progression, the cerebrovascular reserve capacity and breath-holding index were increased and the pulsatility index decreased in the rosuvastatin group, while the cerebrovascular reserve capacity and breath-holding index were decreased, and pulsatility index increased in the placebo group. The changes in gait stability and balance function were independently associated with the changes in the CVR. The odds risks of balance impairment and falls were 2.178 (95% CI: 1.491-3.181) and 3.227 (95% CI: 1.634-6.373), respectively, in the patients with CVR impairment and patients without CVR impairment. Rosuvastatin ameliorated gait and balance disorder progression in older patients with hypertension. This effect might result from the improvement in the CVR. This double-blind clinical trial recruited 943 hypertensive patients aged ≥60 years who were randomly administered rosuvastatin and placebo interventions. The data indicates that rosuvastatin significantly ameliorated the progressions of gait and balance disorders in older hypertensive patients. The cerebrovascular reactivity might play an important mediating role in this amelioration.

Abstract
Objective To provide a synthesis of randomized controlled trials (RCTs) investigating statin-associated muscle symptoms (SAMS) in adults who underwent exercise training intervention. Patients and Methods We systematically searched 5 electronic databases for placebo-controlled RCTs through January 31, 2023. We included short-term and long-term exercise interventions that compared the efficacy and safety of exercise+statin vs exercise+placebo in healthy adults and reported SAMS preintervention and postintervention. Publication bias and methodological study quality assessments were performed. Results Five of 454 potentially qualifying RCTs met the inclusion criteria, all short-term exercise RCTs. Participants were predominantly physically inactive young to middle-aged (M=37.2 y) men (57%), 252 (49%) who were on statin therapy, and 271 (53%) on placebo. Of the 3 RCTs providing qualitative SAMS results, 19 (9%) out of 220 participants reported SAMS on exercise+statin and 10 (4%) out of 234 reported SAMS on exercise+placebo. There was no difference between exercise+statin vs exercise+placebo for maximal oxygen consumption (d=-0.18; 95% CI, -0.37 to 0.00; P=.06) or creatine kinase after short-term exercise (d=0.59; 95% CI, -0.06 to 1.25; P=.08). Participants in the exercise+statin group reduced low-density lipoprotein cholesterol vs exercise+placebo (d=-1.84; 95% CI, -2.28 to -1.39; P<.001). Most of the RCTs exhibited low levels of risk of bias (k=4, 80%) and achieved moderate methodological study quality (75.0%±5.2%). Conclusion Self-reported SAMs tended to be 5% greater after short-term exercise in statin users compared with placebo, although this difference did not achieve statistical significance. There remains an important need for placebo-controlled RCTs investigating the prevalence of statin-induced SAMS during exercise training.

Drug-related sarcopenia as a secondary sarcopenia. Geriatr Gerontol Int 2024; 24:195-203. [PMID: 38158766 DOI: 10.1111/ggi.14770] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Accepted: 11/24/2023] [Indexed: 01/03/2024]
Abstract
Sarcopenia has a significant impact on falls, physical function, activities of daily living, and quality of life in older adults, and its prevention and treatment are becoming increasingly important as the global population ages. In addition to primary age-related sarcopenia, activity-related sarcopenia, disease-related sarcopenia, and nutrition-related sarcopenia have been proposed as secondary sarcopenia. Polypharmacy and potentially inappropriate medication based on multiple diseases cause health problems in older patients. In some cases, drugs used for therapeutic or preventive purposes act on skeletal muscle as adverse drug reactions and induce sarcopenia. Although sarcopenia caused by these adverse drug reactions may be more common in older patients, in particular those taking many medications, drug-related sarcopenia has not yet received much attention. This review summarizes drugs that may induce sarcopenia and emphasizes the importance of drug-related sarcopenia as a secondary sarcopenia. Geriatr Gerontol Int 2024; 24: 195-203.

Statin use impairs muscle strength recovery in post-stroke patients with sarcopenia. Geriatr Gerontol Int 2023; 23:676-683. [PMID: 37485543 DOI: 10.1111/ggi.14646] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2023] [Revised: 06/29/2023] [Accepted: 07/08/2023] [Indexed: 07/25/2023]
Abstract
AIM The effects of statins on muscle health are not well established. Therefore, this study investigated the impact of statin use on muscle strength and mass recovery in patients with sarcopenia after stroke. METHODS This retrospective cohort study included stroke patients with sarcopenia hospitalized between 2015 and 2021 at a post-acute rehabilitation hospital. Sarcopenia was diagnosed using handgrip strength and skeletal muscle mass index measured using bioelectrical impedance analysis according to the 2019 criteria of the Asian Working Group for Sarcopenia. The study outcomes included handgrip strength and skeletal muscle mass index at hospital discharge. We used multivariate analyses to examine whether statin use was independently associated with the outcomes. Statistical significance was set at P < 0.05. RESULTS Of the 586 patients enrolled, 241 (mean age 79.3 years, 44.4% men) presented with sarcopenia and were included in the analysis. Statin use was observed in 61 (25.3%) patients. Statin use was independently negatively associated with handgrip strength at discharge (β = -0.095, P = 0.032), but not with skeletal muscle mass index at discharge (β = 0.019, P = 0.692). CONCLUSIONS Statin use was negatively associated with muscle strength recovery, but not with muscle mass in patients with sarcopenia who underwent rehabilitation after stroke. To maximize outcomes, sufficient consideration is needed for statin use in these patients. Geriatr Gerontol Int 2023; 23: 676-683.

Prolonged Moderate-Intensity Exercise Does Not Increase Muscle Injury Markers in Symptomatic or Asymptomatic Statin Users. J Am Coll Cardiol 2023; 81:1353-1364. [PMID: 37019582 DOI: 10.1016/j.jacc.2023.01.043] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 01/24/2023] [Accepted: 01/30/2023] [Indexed: 04/07/2023]
Abstract
BACKGROUND Statin use may exacerbate exercise-induced skeletal muscle injury caused by reduced coenzyme Q10 (CoQ10) levels, which are postulated to produce mitochondrial dysfunction. OBJECTIVES We determined the effect of prolonged moderate-intensity exercise on markers of muscle injury in statin users with and without statin-associated muscle symptoms. We also examined the association between leukocyte CoQ10 levels and muscle markers, muscle performance, and reported muscle symptoms. METHODS Symptomatic (n = 35; age 62 ± 7 years) and asymptomatic statin users (n = 34; age 66 ± 7 years) and control subjects (n = 31; age 66 ± 5 years) walked 30, 40, or 50 km/d for 4 consecutive days. Muscle injury markers (lactate dehydrogenase, creatine kinase, myoglobin, cardiac troponin I, and N-terminal pro-brain natriuretic peptide), muscle performance, and reported muscle symptoms were assessed at baseline and after exercise. Leukocyte CoQ10 was measured at baseline. RESULTS All muscle injury markers were comparable at baseline (P > 0.05) and increased following exercise (P < 0.001), with no differences in the magnitude of exercise-induced elevations among groups (P > 0.05). Muscle pain scores were higher at baseline in symptomatic statin users (P < 0.001) and increased similarly in all groups following exercise (P < 0.001). Muscle relaxation time increased more in symptomatic statin users than in control subjects following exercise (P = 0.035). CoQ10 levels did not differ among symptomatic (2.3 nmol/U; IQR: 1.8-2.9 nmol/U), asymptomatic statin users (2.1 nmol/U; IQR: 1.8-2.5 nmol/U), and control subjects (2.1 nmol/U; IQR: 1.8-2.3 nmol/U; P = 0.20), and did not relate to muscle injury markers, fatigue resistance, or reported muscle symptoms. CONCLUSIONS Statin use and the presence of statin-associated muscle symptoms does not exacerbate exercise-induced muscle injury after moderate exercise. Muscle injury markers were not related to leukocyte CoQ10 levels. (Exercise-induced Muscle Damage in Statin Users; NCT05011643).

Risk factors predictive of adverse drug events and drug-related falls in aged care residents: secondary analysis from the ReMInDAR trial. Drugs Aging 2023; 40:49-58. [PMID: 36422825 PMCID: PMC9686455 DOI: 10.1007/s40266-022-00983-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/12/2022] [Indexed: 11/26/2022]
Abstract
BACKGROUND Residents of aged-care facilities have high rates of adverse drug events. This study aimed to identify risk factors for adverse drug events in aged-care residents. METHOD This was a secondary study using data from a multicentre randomised controlled trial. Data from 224 residents for whom there was 6 months of baseline information were analysed. We assessed the risk of adverse drug events and falls (post hoc) in the subsequent 6 months. Adverse events were identified via a key word search of the resident care record and adjudicated by a multidisciplinary panel using a modified version of the Naranjo criteria. Covariates identified through univariable logistic regression, including age, sex, medicines, physical activity, cognition (Montreal Cognitive Assessment), previous adverse events and health service use were included in multivariable models. RESULTS Overall, 224 residents were included, with a mean age of 86 years; 70% were female. 107 (48%) residents had an adverse drug event during the 6-month follow-up. Falls and bleeding were experienced by 73 (33%) and 28 (13%) residents, respectively. Age (odds ratio [OR] 1.05, 95% confidence interval [CI] 1.01-1.10), weight (OR 1.02, 95% CI 1.002-1.04), previous fall (OR 2.58, 95% CI 1.34-4.98) and sedative or hypnotic medicine use (OR 1.98, 95% CI 1.52-2.60) were associated with increased risk of adverse drug events. Increased cognition (OR 0.89, 95% CI 0.83-0.95) was protective. Risk factors for falls were previous fall (OR 3.27, 95% CI 1.68-6.35) and sedative or hypnotic medicines (OR 3.05, 95% CI 1.14-8.16). Increased cognition (OR 0.88, 95% CI 0.83-0.95) was protective. CONCLUSION Our results suggest residents with a previous fall, reduced cognition, and prescription of sedative or hypnotic medicines were at higher risk of adverse drug events and should be considered for proactive prevention.

Dietary Acid Load and Bone Health: A Systematic Review and Meta-Analysis of Observational Studies. Front Nutr 2022; 9:869132. [PMID: 35600825 PMCID: PMC9120865 DOI: 10.3389/fnut.2022.869132] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 04/13/2022] [Indexed: 11/13/2022] Open
Abstract
Findings on the association between dietary acid load (DAL) and bone health are conflicting. This study aimed to summarize available studies on the association between DAL and risk of fractures or bone mineral density (BMD) in adults. Online databases including PubMed, Scopus, and Embase were searched for relevant studies published up to June 2021, using pertinent keywords. We identified observational studies (cohort, case-control, and cross-sectional) investigating the association between DAL and risk of fractures or BMD, then selected studies following these reported criteria: RRs with corresponding 95% CIs for the relationship between DAL and fracture risk; correlation coefficients for the association between DAL and BMD; and mean ± SD of BMD values across the categories of DAL. Overall, 17 studies with 80545 individuals were included. There was no significant relationship between the PRAL and fracture risk (Pooled RR: 1.18; 95% confidence interval 0.98 to 1.41, I2 = 60.6%). Moreover, a similar association was observed between the NEAP and fracture risk (Pooled RR: 1.41, 95% CI: 0.79 to 2.52, I2 = 54.1%). The results of five studies from four publications revealed no significant association between dietary PRAL score and femoral and spinal BMD (WMD femoral = −0.01, 95% confidence interval: −0.02 to 0.01, I2 = 76.5%; WMD spinal = −0.01, 95% CI: −0.03 to 0.01, I2 = 56.7%). However, being in the highest category of NEAP was significantly associated with a lower femoral and spinal BMD (WMD femoral = −0.01, 95% CI: −0.02 to −0.00, I2 = 82.1%; WMD spinal = −0.02, 95% CI: −0.03 to −0.01, I2 = 93%). It was showed that adopting diets high in acidity was not associated with risk of fractures. We also found a significant negative relationship between NEAP and BMD. However, DAL based on PRAL was not associated with BMD.

Abstract
Objective To assess the effectiveness of a pharmacist-led intervention using validated tools to reduce medicine-induced deterioration and adverse reactions. Design and setting Multicenter, open-label parallel randomised controlled trial involving 39 Australian aged-care facilities. Participants Residents on ≥4 medicines or ≥1 anticholinergic or sedative medicine. Intervention Pharmacist-led intervention using validated tools to detect signs and symptoms of medicine-induced deterioration which occurred every 8 weeks over 12 months. Comparator Usual care (Residential Medication Management Review) provided by accredited pharmacists. Outcomes Primary outcome was change in Frailty Index at 12 months. Secondary outcomes included changes in cognition, 24-hour movement behaviour by accelerometry, grip strength, weight, adverse events and quality of life. Results 248 persons (median age 87 years) completed the study; 120 in the interventionand, 128 in control arms. In total 575 pharmacist, sessions were undertaken in the intervention arm. There was no statistically significant difference for change in frailty between groups (mean difference: 0.009, 95% CI: −0.028, 0.009, P = 0.320). A significant difference for cognition was observed, with a mean difference of 1.36 point change at 12 months (95% CI: 0.01, 2.72, P = 0.048). Changes in 24-hour movement behaviour, grip strength, adverse events and quality of life were not significantly different between groups. Point estimates favoured the intervention arm at 12 months for frailty, 24-hour movement behaviour and grip strength. Conclusions The use of validated tools by pharmacists to detect signs of medicine-induced deterioration is a model of practice that requires further research, with promising results from this trial, particularly with regards to improved cognition.

Abstract
BACKGROUND The longer-term risks of statins on physical function among people with HIV are unclear. METHODS Longitudinal analysis of Multicenter AIDS Cohort Study men between 40 and 75 years of age with ≥2 measures of gait speed or grip strength. Generalized estimating equations with interaction terms between (1) statin use and age and (2) HIV serostatus, age, and statin use were considered to evaluate associations between statin use and physical function. Models were adjusted for demographics and cardiovascular risk factors. RESULTS Among 2021 men (1048 with HIV), baseline median age was 52 (interquartile range 46-58) years; 636 were consistent, 398 intermittent, and 987 never statin users. There was a significant interaction between age, statin, and HIV serostatus for gait speed. Among people with HIV, for every 5-year age increase, gait speed (m/s) decline was marginally greater among consistent versus never statin users {-0.008 [95% confidence interval (CI) -0.017 to -0.00007]; P = 0.048}, with more notable differences between intermittent and never users [-0.017 (95% CI -0.027 to -0.008); P < 0.001]. Similar results were observed among men without HIV. Significant differences in grip strength (kg) decline were seen between intermittent and never users [-0.53 (95% CI -0.98 to -0.07); P = 0.024] and differences between consistent and never users [-0.28 (95% CI -0.63 to 0.06); P = 0.11] were not statistically significant. CONCLUSIONS Among men with and without HIV, intermittent statin users had more pronounced declines in physical function compared with consistent and never users. Consistent statin use does not seem to have a major impact on physical function in men with or without HIV.

Abstract
OBJECTIVES Antihypertensive drugs (AHTD) and statins have been shown to have effects beyond their primarily designed purpose; here we investigate their possible effect on muscle performance and strength in older adults following a physical exercise programme. DESIGN The Senior PRoject INtensive Training (SPRINT) study is a randomised, controlled clinical trial designed to evaluate the effects of physical exercise on the immune system and muscle performance in older adults. PARTICIPANTS In this secondary analysis, we included 179 independent participants (aged 65 years and above). We applied further categorisation based on medication use: AHTD (including, angiotensin-converting enzyme inhibitors [ACEI], angiotensin II receptor blockers [ARB], β-blockers, and other AHTD) and statins. INTERVENTION Participants were allocated randomly to one of the three exercise protocols: intensive strength training 3 times/week (3 × 10 repetitions at 80% of one-repetition maximum), strength endurance training (2 × 30 repetitions at 40% of one-repetition maximum), or control (passive stretching exercise) for 6 weeks. MEASUREMENTS The change in maximal hand grip strength (GS), muscle fatigue resistance (FR), Muscle Strength Index (MSI), the 6-min walk test (6MWT), and Timed Up and Go Test (TUG) were assessed before and after 6 weeks of training. RESULTS After 6 weeks, muscle strength (MSI and TUG) improved significantly in all training groups compared to baseline, independently of AHTD use. Moreover, AHTD had no effect on exercise improvements, with no significant differences between medication groups, except for TUG in ARB users, which exhibited a significantly lower performance. On the other hand, statin users presented a significantly longer FR time, indicating better performance compared to non-users. Finally, medication did not affect the participants' commitment to the training programme. CONCLUSION Our study showed that statins and ARB usage might affect participant's response to strength training. Nevertheless, 6 weeks of training significantly improved muscle strength and performance irrespective of AHTD or statin use.

Abstract
Whereas the burgeoning population of older adults is intrinsically vulnerable to cardiovascular disease, the utility of many management precepts that were validated in younger adults is often unclear. Whereas biomarker- and imaging-based tests are a major part of cardiovascular disease care, basic assumptions about their use and efficacy cannot be simply extrapolated to many older adults. Biology, physiology, and body composition change with aging, with important influences on cardiovascular disease testing procedures and their interpretation. Furthermore, clinical priorities of older adults are more heterogeneous, potentially undercutting the utility of testing data that are collected. The American College of Cardiology and the National Institutes on Aging, in collaboration with the American Geriatrics Society, convened, at the American College of Cardiology Heart House, a 2-day multidisciplinary workshop, "Diagnostic Testing in Older Adults with Cardiovascular Disease," to address these issues. This review summarizes key concepts, clinical limitations, and important opportunities for research.

U-Shaped Association between Dietary Acid Load and Risk of Osteoporotic Fractures in 2 Populations at High Cardiovascular Risk. J Nutr 2021; 151:152-161. [PMID: 33296471 DOI: 10.1093/jn/nxaa335] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 06/24/2020] [Accepted: 10/05/2020] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Bone contributes to maintaining the acid-base balance as a buffering system for blood pH. Diet composition also affects acid-base balance. Several studies have linked an imbalance in the acid-base system to changes in the density and structure of bone mass, although some prospective studies and meta-analyses suggest that acid load has no deleterious effect on bone. OBJECTIVE The aim of this study was to examine the associations between potential renal acid load (PRAL) and net endogenous acid production (NEAP) and the risk of osteoporotic fractures and bone mineral density (BMD) in 2 middle-aged and elderly Mediterranean populations. METHODS We conducted a longitudinal analysis including 870 participants from the PREvención con DIeta MEDiterranea (PREDIMED) Study and a cross-sectional analysis including 1134 participants from the PREDIMED-Plus study. Participants were adults, aged 55-80 y, either at high cardiovascular risk (PREDIMED) or overweight/obese with metabolic syndrome (PREDIMED-Plus), as defined by the International Diabetes Federation, the American Heart Association, and the National Heart Association. PRAL and NEAP were calculated from validated food-frequency questionnaires. BMD was measured using DXA scans. Fracture information was obtained from medical records. The association between mean PRAL and NEAP and fracture risk was assessed using multivariable-adjusted Cox models. BMD differences between tertiles of baseline PRAL and NEAP were evaluated by means of ANCOVA. RESULTS A total 114 new fracture events were documented in the PREDIMED study after a mean of 5.2 y of intervention and 8.9 y of total follow-up. Participants in the first and third PRAL and NEAP tertiles had a higher risk of osteoporotic fracture compared with the second tertile, showing a characteristically U-shaped association [HR (95% CI): 1.73 (1.03, 2.91) in tertile 1 and 1.91 (1.14, 3.19) in tertile 3 for PRAL, and 1.83 (1.08, 3.09) in tertile 1 and 1.87 (1.10, 3.17) in tertile 3 for NEAP]. Compared with the participants in tertile 1, the participants in the top PRAL and NEAP tertiles had lower BMD [PRAL: mean total femur BMD: 1.029 ± 0.007 and 1.007 ± 0.007 g/cm2; P = 0.006 (tertiles 1 and 3); NEAP: mean total femur BMD: 1.032 ± 0.007 and 1.009 ± 0.007 g/cm2; P = 0.017 (tertiles 1 and 3)]. CONCLUSIONS The results of our study suggest that both high and low dietary acid are associated with a higher risk of osteoporotic fractures, although only high dietary acid was found to have a negative relation to BMD in senior adults with existing chronic health conditions.

Association between statin use and osteoporotic fracture in patients with chronic obstructive pulmonary disease: a population-based, matched case-control study. Lipids Health Dis 2020; 19:232. [PMID: 33143674 PMCID: PMC7641811 DOI: 10.1186/s12944-020-01412-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Accepted: 10/26/2020] [Indexed: 01/30/2023] Open
Abstract
BACKGROUND In the recent years, chronic obstructive pulmonary disease (COPD) has been found to be associated with a higher risk of new-onset osteoporotic fracture (NOF). However, the existence of such an association in the COPD patients receiving statin treatment remains unknown. The present study aimed to investigate the association between COPD and NOF in statin-treated patients. METHODS The present study was conducted over a period of 10 years (January 2004 to December 2013) in Taiwan. COPD patients receiving statin treatment were included in the statin user group, whereas the randomly selected statin non-users, with 1:1 matching for sex, age, index date, and Charlson Comorbidity Index, were included in the statin non-user group. The hazard ratio (HR) of NOFs in COPD patients was estimated between statin user and non-user groups. RESULTS A total of 86,188 cases were identified as the statin-treated patients, and 86,188 subjects were included in the control group of statin non-users. Initially, the risk of NOF was found to be higher among the statin users as compared to non-users [HR, 1.12; 95% confidence interval (CI), 1.01-1.25]. However, the calculation of risk for NOFs after the adjustment for age, sex, comorbidities, and concurrent medications indicated no association of NOF (HR, 0.81; 95% CI, 0.55-1.21) with COPD in patients receiving statin treatment as compared to statin non-users. CONCLUSION The results of the study provided first evidence for the absence of any association between COPD and NOFs in statin-treated patients during a follow-up period of 10 years. Thus, the findings of this study might support the hypothesis stating the potent pleiotropic effects of statins. In clinical practice, these drugs might prove beneficial for the patients with COPD.

Abstract
BACKGROUND People with human immunodeficiency virus (PWH) are at risk for accelerated development of physical function impairment and frailty; both associated with increased risk of falls, hospitalizations, and death. Identifying factors associated with physical function impairment and frailty can help target interventions. METHODS The REPRIEVE trial enrolled participants 40-75 years of age, receiving stable antiretroviral therapy with CD4+ T-cell count >100 cells/mm3, and with low to moderate cardiovascular disease risk. We conducted a cross-sectional analysis of those concurrently enrolled in the ancillary study PREPARE at enrollment. RESULTS Among the 266 participants, the median age was 51 years; 81% were male, and 45% were black, and 28% had hypertension. Body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) was 25 to <30 in 38% and ≥30 in 30%, 33% had a high waist circumference, 89% were physically inactive, 37% (95% confidence interval, 31%, 43%) had physical function impairment (Short Physical Performance Battery score ≤10), and 6% (4%, 9%) were frail and 42% prefrail. In the adjusted analyses, older age, black race, greater BMI, and physical inactivity were associated with physical function impairment; depression and hypertension were associated with frailty or prefrailty. CONCLUSIONS Physical function impairment was common among middle-aged PWH; greater BMI and physical inactivity are important modifiable factors that may prevent further decline in physical function with aging.

Discontinuing statins or not in the elderly? Study protocol for a randomized controlled trial. Trials 2020; 21:342. [PMID: 32307005 PMCID: PMC7169009 DOI: 10.1186/s13063-020-04259-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2019] [Accepted: 03/15/2020] [Indexed: 12/25/2022] Open
Abstract
Background The risk/benefit ratio of using statins for primary prevention of cardiovascular (CV) events in elderly people has not been established. The main objectives of the present study are to assess the cost-effectiveness of statin cessation and to examine the non-inferiority of statin cessation in terms of mortality in patients aged 75 years and over, treated with statins for primary prevention of CV events. Methods The “Statins in the elderly” (SITE) study is an ongoing 3-year follow-up, open-label comparative multi-centre, randomized clinical trial that is being conducted in two parallel groups in outpatient primary care offices. Participants meeting the following criteria are included: people aged 75 years and older being treated with statins as primary prevention for CV events, who provide informed consent. After randomization, patients in the statin-cessation strategy are instructed to withdraw their treatment. In the comparison strategy, patients continue their statin treatment at the usual dosage. The cost-effectiveness of the statin-cessation strategy compared to continuing statins will be estimated through the incremental cost per quality-adjusted life years (QALYs) gained at 36 months, from the perspective of the French healthcare system. Overall mortality will be the primary clinical endpoint. We assumed that the mortality rate at 3 years will be 15%. The sample size was computed to achieve 90% power in showing the non-inferiority of statin cessation, assuming a non-inferiority margin of 5% of the between-group difference in overall mortality. In total, the SITE study will include 2430 individuals. Discussion There is some debate on the value of statins in people over 75 years old, especially for primary prevention of CV events, due to a lack of evidence of their efficacy in this population, potential compliance-related events, drug-drug interactions and side effects that could impair quality of life. Data from clinical trials guide the initiation of medication therapy for primary or secondary prevention of CV disease but do not define the timing, safety, or risks of discontinuing the agents. The SITE study is one of the first to examine whether treatment cessation is a cost-effective and a safe strategy in people of 75 years and over, formerly treated with statins. Trial registration ClinicalTrials.gov: NCT02547883. Registered on 11 September 2015.

The impact of statins on physical activity and exercise capacity: an overview of the evidence, mechanisms, and recommendations. Eur J Appl Physiol 2020; 120:1205-1225.

Abstract
PURPOSE Statins are among the most widely prescribed medications worldwide. Considered the 'gold-standard' treatment for cardiovascular disease (CVD), statins inhibit HMG-CoA reductase to ultimately reduce serum LDL-cholesterol levels. Unfortunately, the main adverse event of statin use is the development of muscle-associated problems, referred to as SAMS (statin-associated muscle symptoms). While regular moderate physical activity also decreases CVD risk, there is apprehension that physical activity may induce and/or exacerbate SAMS. While much work has gone into identifying the epidemiology of SAMS, only recent research has focused on the extent to which these muscle symptoms are accompanied by functional declines. The purpose of this review is to provide an overview of possible mechanisms underlying SAMS and summarize current evidence regarding the relationship between statin treatment, physical activity, exercise capacity, and SAMS development. METHODS PubMed and Google Scholar databases were used to search the most relevant and up-to-date peer-reviewed research on the topic. RESULTS The mechanism(s) behind SAMS, including altered mitochondrial metabolism, reduced coenzyme Q10 levels, reduced vitamin D levels, impaired calcium homeostasis, elevated extracellular glutamate, and genetic polymorphisms, still lack consensus and remain up for debate. Our summation of the evidence leads us to suggest that the etiology of SAMS development is likely multifactorial. Our review also demonstrates that there is limited evidence for statins impairing exercise adaptations or reducing exercise capacity for the majority of the investigated populations. CONCLUSION The available evidence indicates that the benefits of engaging in physical activity while on statin medication largely outweigh the risks.

Abstract
Abstract
Background and aims: Our objective was to determine common risk factors and lifestyle habits associated with atherogenic risk and with the use of lipid-lowering therapy in men with type 2 diabetes.
Material and Methods: A comparative cross-sectional study was performed in the northwestern Algeria during eleven months on adult men patients with type 2 diabetes. Anthropometric parameters, blood pressures and lipid profile were evaluated. Data of common risk factors and lifestyle habits associated to atherosclerosis were compared between two groups according to the lipid lowering therapy use based on statins.
Results: 147 adult men patients with type 2 diabetes were involved in the study, 68 (46.26%) were under statins therapy and 79 (53.74%) were not. Significant associations with statins use were observed regarding the age group of 61-70 years (OR: 0.156 [0.043-0.570]; p=0.005), a salary of less than 30000 Algerian dinars (≈250.60$) (OR: 5.758 [1.299-25.512]; p=0.021), age of diabetes of 2-3 years (OR: 0.105 [0.013-0.867]; p=0.036) as well as with lipid ratios and body mass index (BMI). However, no significant associations were noted regarding the other studied parameters (marital status, educational level, occupation, salary, and family history, smoking status, alcohol consumption and sports practices) with lipid lowering therapy.
Conclusion: Age of patients, diabetes duration, lipid ratios and the low income of patients are the strongest factors associated with the use of lipid lowering therapy (statins). However, largest longitudinal studies are needed to determine whether modifiable lifestyle habits could influence the lipid lowering therapies prescription in diabetic patients over time.

Abstract
Background Lifestyle modification is a key component of cardiovascular disease prevention before and concurrently with pharmacologic interventions. We evaluated whether lifestyle factors change in relation to the initiation of antihypertensive or lipid-lowering medication (statins). Methods and Results The study population comprised 41 225 participants of the FPS (Finnish Public Sector) study aged ≥40 years who were free of cardiovascular disease at baseline and responded to ≥2 consecutive surveys administered in 4-year intervals in 2000-2013. Medication use was ascertained through pharmacy-claims data. Using a series of pre-post data sets, we compared changes in body mass index, physical activity, alcohol consumption, and smoking between 8837 initiators and 46 021 noninitiators of antihypertensive medications or statins. In participants who initiated medication use, body mass index increased more (difference in change 0.19; 95% CI, 0.16-0.22) and physical activity declined (-0.09 metabolic equivalent of task hour/day; 95% CI, -0.16 to -0.02) compared with noninitiators. The likelihood of becoming obese (odds ratio: 1.82; 95% CI, 1.63-2.03) and physically inactive (odds ratio: 1.08; 95% CI, 1.01-1.17) was higher in initiators. However, medication initiation was associated with greater decline in average alcohol consumption (-1.85 g/week; 95% CI, -3.67 to -0.14) and higher odds of quitting smoking (odds ratio for current smoking in the second survey: 0.74; 95% CI, 0.64-0.85). Conclusions These findings suggest that initiation of antihypertensive and statin medication is associated with lifestyle changes, some favorable and others unfavorable. Weight management and physical activity should be encouraged in individuals prescribed these medications.

Abstract
PURPOSE Multiple statin-associated muscle symptoms (SAMS) risk factors usually coexist in a given older diabetic patient, but the association between statin use and physical function in older Asian persons with T2MD remains uncertain. The present study therefore sought to provide insight into this uncertainty through a focused assessment of statin-associated outcomes in Chinese diabetic adults. DESIGN Cross-sectional study. SETTINGS AND PARTICIPANTS The study included 146 participants with T2MD in the Center of Gerontology and Geriatric, West China Hospital. MEASUREMENTS The participants received the comprehensive geriatric assessment (CGA). Statin use and other medical data for each patient were determined via assessment of the inpatient hospital information system. Assessments of physical functions included ADLs, IADLs and the Timed "Up and Go" (TUG) test. Multiple regression analyses were then performed in order to determine the relationship between statin utilization and physical function. RESULTS The average age of these 146 participants (32 women, 21.9%) was 80.00±5.60 years. At enrollment, 78 (53.4%) of the 146 patients were treated with statins. Among the statin users, 48.7% presented with a lack of TUG ability, which was significantly greater than in non-statin users (27.9%). However, the rates of IADL and ADL disabilities did not differ significantly between groups. In a multiple regression analyses, statin use was associated with a three-fold (95% CI 1.06, 9.51) increase in the risk of TUG inability, after adjusted all covariates. CONCLUSIONS There was a significant association between statin use and TUG inability in older Chinese inpatients with diabetes.

Statin-Related Myotoxicity: A Comprehensive Review of Pharmacokinetic, Pharmacogenomic and Muscle Components. J Clin Med 2019; 9:jcm9010022.

Abstract
Statins are a cornerstone in the pharmacological prevention of cardiovascular disease. Although generally well tolerated, a small subset of patients experience statin-related myotoxicity (SRM). SRM is heterogeneous in presentation; phenotypes include the relatively more common myalgias, infrequent myopathies, and rare rhabdomyolysis. Very rarely, statins induce an anti-HMGCR positive immune-mediated necrotizing myopathy. Diagnosing SRM in clinical practice can be challenging, particularly for mild SRM that is frequently due to alternative aetiologies and the nocebo effect. Nevertheless, SRM can directly harm patients and lead to statin discontinuation/non-adherence, which increases the risk of cardiovascular events. Several factors increase systemic statin exposure and predispose to SRM, including advanced age, concomitant medications, and the nonsynonymous variant, rs4149056, in SLCO1B1, which encodes the hepatic sinusoidal transporter, OATP1B1. Increased exposure of skeletal muscle to statins increases the risk of mitochondrial dysfunction, calcium signalling disruption, reduced prenylation, atrogin-1 mediated atrophy and pro-apoptotic signalling. Rare variants in several metabolic myopathy genes including CACNA1S, CPT2, LPIN1, PYGM and RYR1 increase myopathy/rhabdomyolysis risk following statin exposure. The immune system is implicated in both conventional statin intolerance/myotoxicity via LILRB5 rs12975366, and a strong association exists between HLA-DRB1*11:01 and anti-HMGCR positive myopathy. Epigenetic factors (miR-499-5p, miR-145) have also been implicated in statin myotoxicity. SRM remains a challenge to the safe and effective use of statins, although consensus strategies to manage SRM have been proposed. Further research is required, including stringent phenotyping of mild SRM through N-of-1 trials coupled to systems pharmacology omics- approaches to identify novel risk factors and provide mechanistic insight.

Abstract
BACKGROUND Statins are widely used to lower cholesterol concentrations in both primary and secondary prevention of cardiovascular disease. The treatment increases the risk of muscle pain (myalgia) and of type 2 diabetes. However, the underlying mechanisms remain disputed. METHODS We investigated whether statin induced myalgia is coupled to impaired glucose homeostasis using oral glucose tolerance test (OGTT), intravenous glucose tolerance test (IVGTT), and the hyperinsulinemic euglycemic clamp. We performed a cross-sectional study of statin users without CVD (primary prevention) stratified into a statin myalgic (M; n = 25) and a non-myalgic (NM; n = 39) group as well as a control group (C; n = 20) consisting of non-statin users. RESULTS A reduction in the insulin secretion rate during the OGTT was observed in the myalgic group compared with the non-myalgic group (AUC ISROGTT , C: 1032 (683 - 1500); M: 922 (678 - 1091); NM: 1089 (933 - 1391) pmol·L-1 ·min (median with 25%-75% percentiles), but no other measurements indicated impaired β-cell function. We found no other differences between the three groups for other measurements in the OGTT, IVGTT, and euglycemic clamp. Muscle protein content of GLUT4 and hexokinase II was similar between the three groups. CONCLUSIONS We conclude that statin users in primary prevention experiencing myalgia do not have impaired glucose homeostasis compared with other statin users or non-users. We consider this an important aspect in the dialogue between physician and patient regarding statin treatment and adverse effects.

Abstract
CONTEXT Treatment with statins has been associated with increased bone mineral density, but whether this association depends on differences in cortical or trabecular volumetric bone microstructure is unknown. OBJECTIVE The aim of this study was to investigate if treatment with statins is associated with bone microstructure and geometry in older women. DESIGN SETTING AND PARTICIPANTS Older women were included in a population-based study of 3028 women (mean age ± SD, 77.8 ± 1.6 years) from the greater Gothenburg area in Sweden. Information regarding medical history, medication, and lifestyle factors was obtained from validated questionnaires. MAIN OUTCOME Bone geometry and microstructure were measured at the ultradistal and distal (14%) site of radius and tibia using high-resolution peripheral quantitative computed tomography. RESULTS The 803 women in the cohort who used statins had higher body weight, worse physical function, and more frequent cardiovascular disease and diabetes than nonusers (P < 0.05). Statin users had lower cortical porosity (radius, 2.2 ± 1.9 vs 2.5 ± 2.0%; tibia, 5.2 ± 2.4 vs 5.4 ± 2.5; P = 0.01), higher cortical bone density (radius, 1008 ± 39.1 vs 1001 ± 38.4 mg/cm3; tibia, 919 ± 42.6 vs 914 ± 41.5; P < 0.01), and greater cortical area (radius, 60.5 ± 9.6 vs 58.6 ± 9.7 mm2; tibia, 150.0 ± 23.6 vs 146.7 ± 23.8; P < 0.01) than nonusers after adjustment for a large number of confounders, including age, weight, smoking, other medications, and prevalent diseases. CONCLUSIONS Use of statins was associated with better cortical bone characteristics in older women.

Medication Appropriateness in Vulnerable Older Adults: Healthy Skepticism of Appropriate Polypharmacy. J Am Geriatr Soc 2019; 67:1123-1127.

Abstract
Older adults are prescribed a growing number of medications. Polypharmacy, commonly considered the receipt of five or more medications, is associated with a range of adverse outcomes. There is a debate about the reason(s) why. On one side is the assertion that older persons are being prescribed too many medications, with the number of medications increasing the risk of adverse events. On the other side is the observation that polypharmacy is associated both with overprescribing of inappropriate medications and underprescribing of appropriate medications. This leads to the concept of "inappropriate" vs "appropriate" polypharmacy, with the latter resulting from the prescription of many correct medications to persons with multiple chronic conditions. Few studies have examined the health outcomes associated with adding and/or removing medications to address this debate directly. The criteria used to identify underutilized medications are based on results of randomized controlled trials that may not be generalizable to older adults. Several randomized controlled trials and many more observational studies provide evidence that these criteria overestimate medication benefits and underestimate harms. In addition, evidence suggests that the marginal effects of medications added to an already complex regimen differ from their effects when considered individually. Although in selected circumstances adding medications results in benefit to patients, patients with multimorbidity and frailty/disability have susceptibilities that can decrease the likelihood of medication benefit and increase the likelihood of harms. The identification of appropriate polypharmacy requires more robust criteria to evaluate the net effects of complex medication regimens.

Abstract
Polypharmacy is common among older adults and is associated with adverse outcomes. Polypharmacy increases the likelihood of receiving a potentially inappropriate medication (PIM). PIMs have traditionally been defined as medications that have either no benefit (e.g. therapeutic duplication) or increased risk (e.g. altered pharmacodynamics/kinetics with aging). A growing literature supports the notion that these represent only a subset of the potential risks of medications prescribed to older adults. Different authors have proposed new sets of criteria for evaluating medication appropriateness. This narrative review had two objectives: 1) to summarize the contents of these criteria in order to obtain preliminary information about where clinical consensus exists regarding appropriateness; 2) The second was to describe studies examining the risks and benefits of medications identified by the criteria to determine the strength of the evidence supporting the derivation of these criteria. We identified 13 articles sharing overlapping criteria for evaluating appropriateness including: (1) delayed time to benefit; (2) altered benefit-harm ratios in the face of competing risks; (3) effects that do not match patients' goals; and (4) nonadherence. The similarities across the articles suggested strong clinical consensus; however, the articles presented little data directly supporting these criteria. Additional studies provide evidence for the proof of concept that average estimates of benefit and harm derived from randomized controlled trials may differ from the benefits and harms experienced by older persons. However, more data are required to characterize the benefits and harms of medications in the context of the regimen as a whole and the individual's health status.

Abstract
Aims Nonagenarians are a fast growing segment of industrialized countries' populations. Despite a greater risk of cardiovascular disease, there are limited data about their use of preventive therapies and factors guiding decisions regarding their prescription. The aim of this study was to evaluate the prevalence of cardiovascular diseases and the patterns of use of cardiovascular treatments in subjects ≥90 years old. Methods Population-based, cross-sectional study, in all nonagenarians residing in the Community of Madrid (Spain). Data were obtained from their electronic clinical records in primary care. Results Data were available from 59,423 subjects (mean age 93.3 years, 74.2% female, 13.5% with dementia). Prevalence of cardiovascular disease was 24.1% (10.9% with coronary artery disease (CAD), 13.1% with cerebrovascular disease (CVD) and 2.7% with peripheral artery disease(PAD)). In primary prevention, the use of statins and antiplatelet agents was 21.9% and 26.7%, respectively. Of subjects with vascular disease 27.7% were receiving a combined preventive strategy (use of antithrombotics, plus statins, plus blood pressure below 140/90 mmHg). Factors favourably associated with a combined preventive strategy were: female sex (odds ratio (OR) 1.29; 95% confidence interval (CI): 1.11–1.49), being independent versus totally dependent (OR 1.94; 95% CI: 1.43–2.65), diabetes (OR 1.42; 95% CI: 1.20–1.68), and negatively, age (OR 0.87; 95% CI: 0.85–0.90), CVD versus CAD (OR 0.41; 95% CI: 0.35–0.47), PAD versus CAD (OR 0.23; 95% CI: 0.18–0.30), dementia (OR 0.61; 95% CI: 0.49–0.76) and nursing home residency (OR 0.73; 95% CI: 0.57–0.93). Conclusion Nonagenarians have a great burden of cardiovascular diseases and receive a great number of preventive therapies, even in primary prevention, despite their unproven efficacy at these ages.

Abstract
INTRODUCTION Musculoskeletal conditions, including osteoarthritis (OA), result in tremendous disability and cost. Statins are among the most commonly prescribed medications and their use for primary prevention in many otherwise healthy individuals, including those who are physically active, is increasing. There is conflicting evidence regarding the relationship of statin use and musculoskeletal conditions. Given the rising disability associated with musculoskeletal conditions, understanding predisposing factors, including medication-related exposures, deserves further attention. OBJECTIVES We examined the association between statin use and the risk of being diagnosed with non-traumatic arthropathies, use-related injury, and undergoing rehabilitation in a cohort with longitudinal follow-up. METHODS Patients enrolled in a regional military healthcare system between 2003 and 2012 were evaluated in this retrospective cohort study. A propensity score was generated to match statin-users and nonusers using 115 baseline characteristics. Outcomes included ICD-9 diagnoses codes for Agency for Healthcare Research and Quality disease categories of: non-traumatic arthropathies, use-related injury and undergoing rehabilitation. Primary analysis examined the outcomes in statin-users and nonusers after propensity score matching using conditional logistic regression analysis. RESULTS Initially, 60,455 patients were identified. We propensity score-matched 6728 statin users with 6728 nonusers (52 years of age, ~ 47% women). In the propensity score-matched cohort, non-traumatic arthropathies occurred in 59.8% of statin users and 56.0% of nonusers [odds ratio (OR) 1.17, 95% confidence interval (95% CI) 1.09-1.25] and use related injury occurred in 31.9% of statin users and 29.8% of nonusers (OR 1.11, 95% CI 1.03-1.19). There was no difference between statin users and nonusers undergoing rehabilitation (22.6% among statin users, 21.9% among nonusers, OR 1.04, 95% CI 0.96-1.13). CONCLUSION Statin use was associated with a significant increased risk of non-traumatic arthropathies and use-related injury. Our results provide additional data that can inform patient and clinician conversations about the benefits and risks of statin use.

Abstract
PURPOSE OF REVIEW This review examined studies published within the last 16 months that investigated the relationship between statins and physical activity. RECENT FINDINGS These recent studies suggest that statins do not adversely affect cardiorespiratory fitness, muscle strength, athletic performance, or physical activity adherence. One recent study comparing patients with statin-associated myalgia and nonstatin-using controls did report that statins are associated with a slowing of time to peak power output, increased abdominal adiposity, and insulin resistance. Statin users also had different muscle gene expression than controls, but conclusions are limited by the design of that study. SUMMARY Previous reports suggest that statin-associated muscle symptoms such as myalgia, cramps, and weakness occur more frequently in physically active individuals, but the recent studies we reviewed do not provide additional support for this possibility. Well-designed clinical trials are needed to determine whether different statins or statin doses evoke statin-associated muscle symptoms or muscle damage that may reduce cardiorespiratory fitness and adherence to physical activity.

The cholesterol-lowering effect of statins is potentiated by whole grains intake. The Polish Norwegian Study (PONS). Eur J Intern Med 2018; 50:47-51. [PMID: 29137927 DOI: 10.1016/j.ejim.2017.11.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2017] [Revised: 10/04/2017] [Accepted: 11/08/2017] [Indexed: 10/18/2022]
Abstract
BACKGROUND Hypercholesterolemia treatment guidelines emphasize an adequate whole grains (WG) intake, alone or complementary to pharmacological treatment. We conducted this study to compare the prevalence of adequate WG intake and levels of blood lipids according to the statin/WG intake status. METHODS This cross-sectional analysis of a community-based study included 12,754 men and women, age 45-64. Statin use over past 30days was recorded by trained nurses. Food intake over past 12months was assessed by a validated food-frequency questionnaire. Adequate WG intake was defined as ≥3oz-equivalents/day, representing ≥3WGservings/day. RESULTS The prevalence of an adequate WG intake was marginally superior in statin users (26.79%) than non-users (21.51%). This superiority was attenuated after multiple covariates adjustment (PR 1.12, 95%CI 1.02-1.22). Statin users with an adequate WG intake had lower multivariable-adjusted mean blood total cholesterol (185.14mg/dL vs. 190.14mg/dL) and LDL cholesterol (103.30mg/dL vs. 108.19mg/dL) than those with an inadequate WG intake. Statin users with an adequate WG intake had lower odds (OR, 95% CI) of having TC≥240mg/dL (OR 0.67, 95% CI 0.46-0.98) and lower odds of having LDL≥100mg/dL (OR 0.72, 95% CI 0.58-0.89), compared to statin users with inadequate WG intake. A subgroup analysis restricted to those with prevalent CVD yielded similar results. CONCLUSIONS In this community based sample of middle-aged adults, only one in four statin users had adequate whole grain intake. Statin users with adequate WG intake had statistically and clinically significant lower levels of blood total- and LDL-cholesterol.

Pravastatin improves risk factors but not ischaemic tolerance in obese rats. Eur J Pharmacol 2018; 826:148-157. [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.

Abstract
PURPOSE OF REVIEW Cardiovascular diseases account for nearly one third of all deaths globally. Improving exercise capacity and cardiorespiratory fitness (CRF) has been an important target to reduce cardiovascular events. In addition, the American Heart Association defined decreased physical activity as the fourth risk factor for coronary artery disease. Multiple large cohort studies have evaluated the impact of CRF on outcomes. In this review, we will discuss the role of CRF in reducing cardiovascular morbidity and mortality. RECENT FINDINGS Recent data suggest that CRF has an important role in reducing not only cardiovascular and all-cause mortality, but also incident myocardial infarction, hypertension, diabetes, atrial fibrillation, heart failure, and stroke. Most recently, its role in cancer prevention started to emerge. CRF protective effects have also been seen in patients with prior comorbidities like prior coronary artery disease, heart failure, depression, end-stage renal disease, and stroke. The prognostic value of CRF has been demonstrated in various patient populations and cardiovascular conditions. Higher CRF is associated with improved survival and decreased incidence of cardiovascular diseases (CVD) and other comorbidities including hypertension, diabetes, heart failure, and atrial fibrillation.

Abstract
Sedentary behavior has emerged as an independent cardiovascular disease risk factor. Uncertainty exists about the behaviors of statin users, who may exhibit either a healthy adherer or a false reassurance effect. We conducted this study in order to assess and compare TV viewing among statin users and nonusers. We used data from a cross-sectional study of 12,754 participants, from south-east Poland, age 45 to 64 years in 2010–11. Statin use during last 30 days was recorded by trained nurses. Participants reported time spent viewing TV/week. There were 1728 (13.5%) statin users of which 628 (36.34%) had cardiovascular diseases. The prevalence of viewing TV ≥ 21 h/week was higher among statin users (29.72%) compared to non-users (23.10%) and remained 15% higher after adjusting for age, sex, education, smoking, chronic obstructive pulmonary disease and other chronic diseases (prevalence ratio, PR 1.15, 95% CI 1.06 to 1.25). We found a similar pattern in both those with and without prevalent cardiovascular disease. In conclusion, we found a higher prevalence of prolonged TV-viewing among statin users than non-users. Future studies are needed to explore innovative behavioral interventions and patient counseling strategies to reduce TV viewing among statin users. Sedentary behavior is considered an independent cardiovascular disease risk factor. Statin users are recommended to have an active lifestyle. We found that more statin users than nonusers watch TV > 21 h/week. Novel behavioral interventions are needed to reduce sedentary among statin users.

Combining Potent Statin Therapy with Other Drugs to Optimize Simultaneous Cardiovascular and Metabolic Benefits while Minimizing Adverse Events. Korean Circ J 2017; 47:432-439.

Abstract
Hypercholesterolemia and hypertension are among the most important risk factors for cardiovascular (CV) disease. They are also important contributors to metabolic diseases including diabetes that further increase CV risk. Updated guidelines emphasize targeted reduction of overall CV risks but do not explicitly incorporate potential adverse metabolic outcomes that also influence CV health. Hypercholesterolemia and hypertension have synergistic deleterious effects on interrelated insulin resistance and endothelial dysfunction. Dysregulation of the renin-angiotensin system is an important pathophysiological mechanism linking insulin resistance and endothelial dysfunction to atherogenesis. Statins are the reference standard treatment to prevent CV disease in patients with hypercholesterolemia. Statins work best for secondary CV prevention. Unfortunately, most statin therapies dose-dependently cause insulin resistance, increase new onset diabetes risk and exacerbate existing type 2 diabetes mellitus. Pravastatin is often too weak to achieve target low-density lipoprotein cholesterol levels despite having beneficial metabolic actions. Renin-angiotensin system inhibitors improve both endothelial dysfunction and insulin resistance in addition to controlling blood pressure. In this regard, combined statin-based and renin-angiotensin system (RAS) inhibitor therapies demonstrate additive/synergistic beneficial effects on endothelial dysfunction, insulin resistance, and other metabolic parameters in addition to lowering both cholesterol levels and blood pressure. This combined therapy simultaneously reduces CV events when compared to either drug type used as monotherapy. This is mediated by both separate and interrelated mechanisms. Therefore, statin-based therapy combined with RAS inhibitors is important for developing optimal management strategies in patients with hypertension, hypercholesterolemia, diabetes, metabolic syndrome, or obesity. This combined therapy can help prevent or treat CV disease while minimizing adverse metabolic consequences.

The effects of statins on exercise and physical activity. J Clin Lipidol 2017; 11:1134-1144.

Abstract
OBJECTIVE We sought to review studies examining the effect of statins on symptoms of exercise tolerance, markers of muscle injury and activity levels in physical active individuals. BACKGROUND Statin therapy reduces atherosclerotic cardiovascular disease (CVD) events. Regular physical activity is also associated with reduced CVD events, but statin therapy can produce muscle complaints, which may be more frequent in physically active individuals. We reviewed the literature to determine the effects of statins on symptoms, exercise performance and activity levels in physically active individuals. METHODS We performed a PubMed search to identify English language articles reporting on statins and their effect on athletic/exercise performance, and symptoms in active individuals. RESULTS We identified 65 articles, 32 of which provided sufficient information to be included in this review. Seventeen of the 32 studies examined the incidence of myalgia while exercising on statins, and showed that myalgia was increased in 8 of the 17 (47%) of these studies. Of the 17 studies examining the effects of statin therapy on muscle injury, 6 (35%) studies reported that statins augment the increase in creatine kinase (CK) produced by exercise. There were 10 studies that examined statin effects on aerobic exercise performance, only 3 of which (33%) concluded that statins decreased performance. Two (25%) of the 8 studies examined the effects of statins on muscular strength and suggested that statins decreased muscular strength, whereas 2 (25%) reported increased strength. Statins did not consistently affect physical activity levels since statins were associated with an increase in activity in 3 of the 5 studies examining habitual exercise. None of the studies showed a relationship between statins use and exercise and an increase in myalgia or a decrease in exercise performance. There was also no correlation between intensity of statin therapy and an effect on these variables. CONCLUSION Statins may increase the incidence of exercise-related muscle complaints and in some studies augment the exercise-induced rise in muscle enzymes, but statins do not consistently reduce muscle strength, endurance, overall exercise performance or physical activity.

Abstract
Multiple medication use, or polypharmacy, is common in people undergoing rehabilitation. Polypharmacy is also common in older people, where it has the potential to impact on habitual physical activity. Despite this, the interactions between medication, disease, activity, and rehabilitation outcomes are insufficiently researched. In this review, we consider common classes of medications that can affect physical activity levels and outcomes of rehabilitation. We consider medications that improve disease processes and improve limiting symptoms (eg, breathlessness in heart failure and lung disease, pain in arthritis), unwanted side effects of medications (eg, central slowing caused by opioids and hypnotics), and also medication classes that might have the ability to improve activity and rehabilitation outcomes via beneficial effects on neuromuscular function (eg, angiotensin-converting enzyme inhibitors). We conclude by giving practical advice on how to review and optimise medication use to support habitual physical activity and ensure the best results from rehabilitation.

Abstract
Background Exercise and statins reduce cardiovascular disease (CVD). Exercise capacity may be assessed using cardiopulmonary exercise testing (CPET). Whether statin medication is associated with CPET parameters is unclear. We investigated if statins are related with exercise capacity during CPET in the general population. Methods Cross-sectional data of two independent cohorts of the Study of Health in Pomerania (SHIP) were merged (n = 3,500; 50% males). Oxygen consumption (VO2) at peak exercise (VO2peak) and anaerobic threshold (VO2@AT) was assessed during symptom-limited CPET. Two linear regression models related VO2peak with statin usage were calculated. Model 1 adjusted for age, sex, previous myocardial infarction, and physical inactivity and model 2 additionally for body mass index, smoking, hypertension, diabetes and estimated glomerular filtration rate. Propensity score matching was used for validation. Results Statin usage was associated with lower VO2peak (no statin: 2336; 95%-confidence interval [CI]: 2287–2,385 vs. statin 2090; 95%-CI: 2,031–2149 ml/min; P < .0001) and VO2@AT (no statin: 1,172; 95%-CI: 1,142–1,202 vs. statin: 1,111; 95%-CI: 1,075–1,147 ml/min; P = .0061) in males but not females (VO2peak: no statin: 1,467; 95%-CI: 1,417–1,517 vs. statin: 1,503; 95%-CI: 1,426–1,579 ml/min; P = 1.00 and VO2@AT: no statin: 854; 95%-CI: 824–885 vs. statin 864; 95%-CI: 817–911 ml/min; P = 1.00). Model 2 revealed similar results. Propensity scores analysis confirmed the results. Conclusion In the general population present statin medication was related with impaired exercise capacity in males but not females. Sex specific effects of statins on cardiopulmonary exercise capacity deserve further research.

Abstract
Cardiac rehabilitation (CR) improves exercise capacity (EC), but not all CR participants achieve such improvements. Our primary aim was to develop a tool to identify those with suboptimal improvement in EC after CR. We retrospectively analyzed 541 patients enrolled in a phase-II CR program after a cardiac event or intervention from 2003 to 2014. EC was assessed with the 6-minute walk test. We developed a multivariate linear regression model and corresponding nomogram to predict EC after CR. The predictors included in the final model were age, gender, baseline EC, primary referral diagnosis, body mass index, systolic blood pressure at rest, triglycerides, low-density lipoprotein cholesterol, lipid-lowering medication use, and an interaction term of low-density lipoprotein cholesterol with lipid-lowering therapy. The prediction model was internally validated using bootstrap methods, and a nomogram was created for ease of use. In conclusion, this tool helps to identify those patients with suboptimal improvement in EC who could be targeted for individualized interventions to increase their performance.

Abstract
OBJECTIVES There are little data on the potential benefits and adverse events of statins among physically fit individuals. Our objective was to examine the associations of statin use with beneficial cardiovascular outcomes and adverse events in active duty military (a surrogate for high level of physical fitness). DESIGN This is a retrospective propensity score-matched cohort study of healthy active duty military (fiscal years [FY] 2002-2011). METHODS Statin-users received statins during FY 2005 as their only prescription medication. FY 2002-2004 was used to describe baseline characteristics; and FY 2006-2011were used to capture outcomes. Study outcomes included major acute cardiovascular events (MACE), diabetes mellitus and its complications, kidney diseases, musculoskeletal diseases, obesity, and malignancy. RESULTS We propensity score matched 837 statin-users to 2488 nonusers. During follow-up, 1.6% statin-users and 1.5% nonusers were diagnosed with MACE (odds ratio [OR] 1.05, 95% confidence interval [CI] 0.55-1.98), 12.5% of statin-users and 5.8% of nonusers were diagnosed with diabetes (OR 2.34, 95% CI 1.79-3.04), and 1.7% statin- users and 0.7% nonusers were diagnosed with diabetes with complication (OR 2.47, 95% CI 1.21-5.04). There were no differences in rates of other adverse events. CONCLUSIONS Among healthy physically active individuals, statin use was associated with doubled the odds of diabetes and diabetic complications without countervailing cardiovascular benefits.

Abstract
Background Lifestyle and dietary advice typically precedes or accompanies the prescription of statin medications. However, evidence for adherence to this advice is sparse. The objective was to compare saturated fat intake, exercise, alcohol consumption and smoking between statin users and non-users in Australia. Methods Data were analysed for 4614 participants aged ≥37 years in the Australian Diabetes, Obesity and Lifestyle study in 2011-2012. Statin use, smoking status and physical activity were self-reported. Saturated fat and alcohol intake were measured via a food frequency questionnaire. Multinomial logistic regression was used to compute adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the associations between statin use and the four lifestyle factors. All models were adjusted for age, sex, education, number of general practitioner visits, body mass index, hypertension, diabetes and prior cardiovascular diseases. Results In total 1108 (24%) participants used a statin. Statin users were 29% less likely to be within the highest quartile versus the lowest quartile of daily saturated fat intake compared to non-users (OR 0.71, 95% CI 0.54-0.94). There were no statistically significant associations between statin use and smoking, physical activity or alcohol consumption. Conclusions Smoking status, alcohol consumption and exercise level did not differ between users and non-users of statins. However, statin users were less likely to consume high levels of saturated fat than non-users. We found no evidence that people took statins to compensate for a poor diet or lifestyle.

Relation of Statin Use and Mortality in Community-Dwelling Frail Older Patients With Coronary Artery Disease. Am J Cardiol 2016; 118:1624-1630.

Abstract
Clinical decision-making for statin treatment in older patients with coronary artery disease (CAD) is under debate, particularly in community-dwelling frail patients at high risk of death. In this retrospective observational study on 2,597 community-dwelling patients aged ≥65 years with a previous hospitalization for CAD, we estimated mortality risk assessed with the Multidimensional Prognostic Index (MPI), based on the Standardized Multidimensional Assessment Schedule for Adults and Aged Persons (SVaMA), used to determine accessibility to homecare services/nursing home admission in 2005 to 2013 in the Padua Health District, Veneto, Italy. Participants were categorized as having mild (MPI-SVaMA-1), moderate (MPI-SVaMA-2), and high (MPI-SVaMA-3) baseline mortality risk, and propensity score-adjusted hazard ratios (HRs) of 3-year mortality rate were calculated according to statin treatment in these subgroups. Greater MPI-SVaMA scores were associated with lower rates of statin treatment and higher 3-year mortality rate (MPI-SVaMA-1 = 23.4%; MPI-SVaMA-2 = 39.1%; MPI-SVaMA-3 = 76.2%). After adjusting for propensity score quintiles, statin treatment was associated with lower 3-year mortality risk irrespective of MPI-SVaMA group (HRs [95% confidence intervals] 0.45 [0.37 to 0.55], 0.44 [0.36 to 0.53], and 0.28 [0.21 to 0.39] in MPI-SVaMA-1, -2, and -3 groups, respectively [interaction test p = 0.202]). Subgroup analyses showed that statin treatment was also beneficial irrespective of age (HRs [95% confidence intervals] 0.38 [0.27 to 0.53], 0.45 [0.38 to 0.54], and 0.44 [0.37 to 0.54] in 65 to 74, 75 to 84, and ≥85 year age groups, respectively [interaction test p = 0.597]). In conclusion, in community-dwelling frail older patients with CAD, statin treatment was significantly associated with reduced 3-year mortality rate irrespective of age and multidimensional impairment, although the frailest patients were less likely to be treated with statins.

Correlates of Achieving Statin Therapy Goals in Children and Adolescents with Dyslipidemia. J Pediatr 2016; 178:149-155.e9. [PMID: 27592099 PMCID: PMC5085848 DOI: 10.1016/j.jpeds.2016.08.003] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2016] [Revised: 06/30/2016] [Accepted: 08/02/2016] [Indexed: 12/23/2022]
Abstract
OBJECTIVE To determine the real-world effectiveness of statins and impact of baseline factors on low-density lipoprotein cholesterol (LDL-C) reduction among children and adolescents. STUDY DESIGN We analyzed data prospectively collected from a quality improvement initiative in the Boston Children's Hospital Preventive Cardiology Program. We included patients ≤21 years of age initiated on statins between September 2010 and March 2014. The primary outcome was first achieving goal LDL-C, defined as <130 mg/dL, or <100 mg/dL with high-level risk factors (eg, diabetes, etc). Cox proportional hazards models were used to assess the impact of baseline clinical and lifestyle factors. RESULTS Among the 1521 pediatric patients evaluated in 3813 clinical encounters over 3.5 years, 97 patients (6.3%) were started on statin therapy and had follow-up data (median age 14 [IQR 7] years, 54% were female, and 24% obese, 62% with at least one lifestyle risk factor). The median baseline LDL-C was 215 (IQR 78) mg/dL, and median follow-up after starting statin was 1 (IQR 1.3) year. The cumulative probability of achieving LDL-C goal within 1 year was 60% (95% CI 47-69). A lower probability of achieving LDL-C goals was associated with male sex (HR 0.5 [95% CI 0.3-0.8]) and higher baseline LDL-C (HR 0.92 [95% CI 0.87-0.98] per 10 mg/dL), but not age, body mass index percentile, lifestyle factors, or family history. CONCLUSIONS The majority of pediatric patients started on statins reached LDL-C treatment goals within 1 year. Male patients and those with greater baseline LDL-C were less likely to be successful and may require increased support.

Abstract
PURPOSE Statin therapy can result in muscle pain, cramps, and weakness that may limit physical activity, although reports are mixed. We conducted a randomized control trial to examine the effect of atorvastatin on habitual physical activity levels in a large sample of healthy adults. METHODS Participants (n = 418) were statin-naive adults (44.0 ± 16.1 yr (mean ± SD)) who were randomized and double-blinded to 80 mg · d(-1) of atorvastatin or placebo for 6 months. Accelerometers were worn for 96 h before and after drug treatment. Repeated-measures analysis tested physical activity levels after versus those before drug treatment among groups with age and VO2max as covariates. RESULTS In the total sample, sedentary behavior increased (19.5 ± 5.1 min · d(-1)), whereas light-intensity (9.1 ± 3.0 min · d(-1)) and moderate-intensity (9.7 ± 2.8 min · d(-1)) physical activity decreased, as did total activity counts (17.8 ± 6.3 d × 10(-3)) over 6 months (P < 0.01), with no differences between groups. The atorvastatin group increased sedentary behavior (19.8 ± 7.4 min · d(-1)) and decreased light-intensity (10.7 ± 4.3 min · d(-1)) and moderate-intensity (8.5 ± 4.0 min · d(-1)) physical activity (P < 0.05). On the other hand, the placebo group increased sedentary behavior (19.2 ± 7.1 min · d(-1)) and decreased moderate-intensity (11.0 ± 3.8 min · d(-1)) and total physical activity counts (-23.8 ± 8.8 × 10(-3) d(-1)) (P < 0.05). CONCLUSIONS Time being sedentary increased and physical activity levels decreased in the total sample over 6 months of drug treatment, independent of group assignment. Our results suggest that statins do not influence physical activity levels any differently from placebo, and the lack of inclusion of a placebo condition may provide insight into inconsistencies in the literature.

Association of statins with diabetes mellitus and diabetic complications: role of confounders during follow-up. J Investig Med 2016; 65:32-42.

Abstract
Studies have associated statin use with increased risk of diabetes and diabetic complications. These studies often ensure comparability of statin users and non-users at baseline; however, most studies neglect to consider confounders that occur during follow-up. Failure to consider these confounders, such as new medications or procedures, may result in identification of a spurious association between statins and outcomes. The objective of this study was to examine the association of statins with diabetes mellitus and diabetic complications; and to examine potential confounders during the follow-up period that might affect this relationship. We conducted a retrospective cohort study using Tricare data (from October 1, 2003 to March 31, 2012). We propensity score-matched statin users and non-users on 115 baseline characteristics before starting statins; these characteristics would be potentially associated with the use of statins or the outcomes of interest. Outcomes included the risk of diabetes mellitus and diabetic complications. Out of 60,455 patients (10,910 statin users and 49,545 non-users), we propensity score-matched 6728 statin users to 6728 non-users. Statin users had higher ORs for diabetes (OR 1.34, 95% CI 1.24 to 1.44) and diabetes with complications (OR 1.28, 95% CI 1.16 to 1.42). Adjustment for potential confounders that occurred during the follow-up period did not explain or diminish the association between statins and adverse outcomes. Statin users in comparison to similar non-users were more commonly diagnosed with diabetes and diabetic complications, even after adjustment for potential confounders that occurred during the follow-up period.
