Abstract
AIM To investigate the association between medication use and long-term all-cause mortality in a Brazilian stroke cohort. METHODS Both ischemic and hemorrhagic stroke were evaluated. Medication use was assessed as: never, only pre-stroke, only post-stroke, and continuous use. We evaluated anti-hypertensives, anti-diabetics, lipid-lowering drugs, anti-platelets, and anti-coagulants. Cox regression models were adjusted for sociodemographic and cardiovascular risk factors. RESULTS Among 1173 incident stroke cases (median age: 68; 86.8% were ischemic, 70% first-ever stroke), medication use was low (overall: 17.5% pre-stroke, 26.4% post-stroke, and 40% were under continuous use). Anti-hypertensives and anti-platelets (aspirin) were the continuous cardiovascular medications used most often, at 83.5% and 72%, respectively, while statins (39.7%) and anti-diabetics (31.3%) were the least used. Medication use (pre-stroke, post-stroke and continuous use) was associated with a reduction in all-cause mortality risk, particularly among those under continuous use (multivariable hazard ratio, 0.52; 95% confidence interval (CI), 0.46-0.66) compared with never-users. Among ischemic stroke patients, this effect was similar (multivariable hazard ratio, 0.52; 95% CI, 0.40-0.68). No significant associations were evident among hemorrhagic stroke patients. CONCLUSIONS The risk of all-cause mortality was reduced by 48% among those with ischemic stroke under continuous use of medications. Secondary prevention should be emphasized more strongly in clinical practice. Geriatr Gerontol Int 2022; ••: ••-••.

Abstract
Introduction Metabolic syndrome (MetS) is defined as a syndrome of truncal obesity, insulin resistance, hypertension, hypertriglyceridemia, and dyslipidemia. It is well known that MetS increases the risk of cardiovascular disease and adverse events. Each of its components is associated with an increased risk of cardiovascular disease, but data on the association with ischemic stroke are scarce. At the international level, a significant body of research has been conducted on this issue, but the situation is very different in Pakistan. Very little data are present on the subject matter. This study is an endeavor in this direction, generating data, that can be used in early identification and developing treatment services for patients with ischemic stroke having MetS. Aims To determine the frequency of MetS in ischemic stroke patients admitted to a tertiary care hospital in Karachi, Pakistan. Methods This six-month observational and cross-sectional study was conducted at Medical Unit I, Jinnah Postgraduate Medical Centre from July 1, 2019, to December 31, 2019. Patients with a diagnosis of acute ischemic stroke were enrolled. Detailed history, physical examination, and biochemical measurements were noted. The presence of MetS was defined in accordance with the National Cholesterol Education Program (NCEP) Adult Treatment Panel III (ATP III)/American Heart Association (AHA) guidelines. Results A total of 224 patients fulfilling the inclusion criteria were inducted into this study. The mean age of presentation was 61.04 ± 14.72 years, and more than two-thirds of the patients were ≥60 years of age. A total of 150 (66.96%) patients with ischemic stroke also had MetS. The male-to-female ratio in this group was 2:1. The most common variables constituting the MetS were truncal obesity, hypertension, and dyslipidemia. The median MetS score was 3. Conclusions MetS is highly prevalent in patients presenting with ischemic stroke irrespective of age or gender. The three most deranged and common components of MetS in these patients are truncal obesity, hypertension, and dyslipidemia.

Abstract
Introduction Stroke is a leading cause of chronic disability and death in both developing and developed countries. A significant proportion of stroke patients are human immunodeficiency virus (HIV) positive. About half of the HIV patients experience some sort of neurological deficit in their lifetimes. The exact reason for the occurrence of stroke in HIV infected patients is poorly understood. The purpose of our study is to determine the frequency of HIV among patients admitted with acute stroke. Materials and methods This cross-sectional study is conducted at a major metropolitan hospital in Karachi for six months. A total of 130 patients of stroke between the ages of 30 and 70 years of either gender were included in this study. A complete history was taken and a physical examination was performed. Each patient underwent a battery of tests that included HIV serology, lipid profile, electrocardiography (ECG), chest X-ray (posteroanterior (PA) view), and computed tomography (CT) scan of the brain. Carotid Doppler ultrasonography to assess carotid artery stenosis was also ordered. The means and standard deviations of age and cluster of differentiation 4 (CD4) cell count were calculated. The frequencies and proportions of gender, diabetes mellitus (DM), hypertension (HTN), smoking, obesity, dyslipidemia, carotid artery stenosis, and HIV status were calculated. Stratification was done by applying the chi-square test and assuming p-value ≤0.05 as significant. This helped analyze the association of age, gender, DM, HTN, smoking, obesity, dyslipidemia, and carotid artery stenosis to the frequency of HIV. Results The mean age of the study population was 55.54 ± 11.166 years. There were 39 (30%) patients <50 years of age while 91 (70%) patients were ≥50 years of age. Gender distribution showed that 86 (66.15%) patients were male, and 44 (33.85%) patients were female. Furthermore, 71 (54.62%) patients were hypertensive, 53 (40.77%) were diabetic, 62 (47.69%) were smokers, 49 (37.69%) were obese, 52 (40%) had dyslipidemia, and 77 (59.23%) had carotid artery stenosis. The frequency of HIV was noted at 24 (18.46%). The mean CD4 count was estimated at 241 ± 103.295 cells/mm3. Stratification showed a significant relationship between the frequency of HIV with only gender (p=0.01) and dyslipidemia (p=0.037). Conclusion HIV infection in patients with stroke is not uncommon. Patients who are male, younger in age, have dyslipidemia, belong to a low socioeconomic class, or have a bad sexual history are more likely to have HIV as an underlying cause of stroke. The exact pathogenesis of such a stroke and the role of antiretroviral therapy in the prevention and treatment of this group of stroke are not completely understood and need further analysis.

Abstract
Statins are effective cholesterol-lowering drugs for reducing the risks of mortality and morbidity of cardiovascular diseases. Increasing evidence has shown that statin use is associated with a significant beneficial effect in patients with ischemic stroke. Both pre-stroke and post-stroke statin use has been found to be beneficial in ischemic stroke. Furthermore, good adherence is associated with a better clinical outcome, and statin withdrawal is associated with a poor functional outcome in patients with ischemic stroke. High-intensity statin therapy is advocated for the treatment of ischemic stroke. However, there are concerns regarding the adverse effects associated with statin use in ischemic stroke such as intracranial hemorrhage. In this review, we summarize the beneficial effect of statin use in ischemic stroke and discuss the potential risks associated with statin therapy.

Abstract
BACKGROUND Acute stroke is the third leading cause of death in Taiwan. Although statin therapy is widely recommended for stroke prevention, little is known about the epidemiology of statin therapy after acute ischemic stroke (AIS) in Taiwan. To investigate the effects of statin therapy on recurrent stroke, intracranial hemorrhage (ICH), coronary artery disease (CAD), cost of hospitalization and mortality, we conducted a nationwide population-based epidemiologic study. METHODS Cases of AIS were identified from the annual hospitalization discharge diagnoses of the National Health Insurance Research Database with the corresponding International Classification of Diseases, ninth revision codes from January 2001 to December 2010. We divided the AIS patients into three groups: non-statin, pre-stroke statin and post-stroke statin. RESULTS A total of 422 671 patients with AIS (including 365 419 cases in the non-statin group, 22 716 cases in the pre-stroke statin group and 34 536 cases in the post-stroke statin group) were identified. When compared to the non-statin group, both statin groups had a lower recurrent stroke risk [pre-stroke statin: odds ratio (OR) = 0.84; 95% confidence interval (CI) = 0.82-0.87; P < 0.0001; post-stroke statin: OR = 0.89; 95% CI = 0.86-0.91; P < 0.0001], lower ICH risk (pre-statin: OR = 0.75; 95% CI = 0.69-0.82; P < 0.0001; post-stroke statin: OR = 0.75; 95% CI = 0.71-0.81; P < 0.0001), and a lower mortality rate (pre-stroke statin: OR = 0.56; 95% CI = 0.53-0.59; P < 0.0001; post-stroke statin: OR = 0.51; 95% CI = 0.48-0.53; P < 0.0001). In terms of CAD, only the post-statin group had a lower risk (OR = 0.81; 95% CI = 0.79-0.84; P < 0.0001) than the non-statin group. The post-statin group had the lowest 1-year medical costs after index discharge among the three groups. CONCLUSIONS Statin therapy reduced the risks of recurrent stroke, CAD, ICH and the first year mortality in patients after AIS. Treatment with statin therapy after AIS is a cost-effective strategy in Taiwan.

Abstract
OBJECTIVE Whether statins increase the risk of intracerebral haemorrhage (ICH) in patients with a previous stroke remains uncertain. This study addresses the evidence of statin therapy on ICH and other clinical outcomes in patients with previous ischaemic stroke (IS) or ICH. METHODS A systematic literature review and meta-analysis was performed in conformity with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to assess observational and randomised studies comparing statin therapy with control (placebo or no treatment) in patients with a previous ICH or IS. The risk ratios (RR) for the primary outcome (ICH) and secondary outcomes (IS, any stroke, mortality and function) were pooled using random effects meta-analysis according to stroke subtype. RESULTS Forty-three studies with a combined total of 317 291 patient-years of follow-up were included. In patients with previous ICH, statins had no significant impact on the pooled RR for recurrent ICH (1.04, 95% CI 0.86 to 1.25; n=23 695); however, statins were associated with significant reductions in mortality (RR 0.49, 95% CI 0.36 to 0.67; n=89 976) and poor functional outcome (RR 0.71, 95% CI 0.67 to 0.75; n=9113). In patients with previous IS, statins were associated with a non-significant increase in ICH (RR 1.36, 95% CI 0.96 to 1.91; n=103 525), but significantly lower risks of recurrent IS (RR 0.74, 95% CI 0.66 to 0.83; n=53 162), any stroke (RR 0.82, 95% CI 0.67 to 0.99; n=55 260), mortality (RR 0.68, 95% CI 0.50 to 0.92; n=74 648) and poor functional outcome (RR 0.83, 95% CI 0.76 to 0.91; n=34 700). CONCLUSIONS Irrespective of stroke subtype, there were non-significant trends towards future ICH with statins. However, this risk was overshadowed by substantial and significant improvements in mortality and functional outcome among statin users. TRIAL REGISTRATION NUMBER CRD42017079863.

Abstract
The contribution of lipids, including low- and high-density lipoprotein cholesterol (LDL-C and HDL-C, respectively) and triglycerides (TG), to stroke outcomes is still debated. We sought to determine the impact of LDL-C concentrations on the outcome of patients with ischemic stroke in the anterior circulation who received treatment with endovascular thrombectomy (EVT). We performed a retrospective analysis of consecutive patients with acute ischemic stroke treated at a tertiary center between 2012 and 2016. Patients treated with EVT for large artery occlusion in the anterior circulation were selected. The primary endpoint was functional outcome at 3 months as measured with the modified Rankin Scale (mRS). Secondary outcome measures included hospital death and final infarct volume (FIV). Blood lipid levels were determined in a fasting state, 1 day after admission. We studied a total of 174 patients (44.8% men) with a median age of 74 years (interquartile range [IQR] 61–82) and median National Institutes of Health Stroke Scale at admission of 18 (14–22). Bridging therapy with intravenous tissue-plasminogen activator (t-PA) was administered in 122 (70.5%). The median LDL-C was 90 mg/dl (72–115). LDL-C demonstrated a U-type relationship with FIV (p = 0.036). Eighty-three (50.0%) patients had an mRS of 0–2 at 3 months. This favorable outcome was independently associated with younger age (OR 0.944, 95% CI 0.90–0.99, p = 0.012), thrombolysis in cerebral infarction 2b-3 reperfusion (OR 5.12, 95% CI 1.01–25.80, p = 0.015), smaller FIV (0.97 per cm3, 95% CI 0.97–0.99, p < 0.001), good leptomeningeal collaterals (OR 5.29, 95% CI 1.48–18.9, p = 0.011), and LDL-C more than 77 mg/dl (OR 0.179, 95% CI 0.04–0.74, p = 0.018). A higher LDL-C concentration early in the course of a stroke caused by large artery occlusion in the anterior circulation is independently associated with a favorable clinical outcome at 3 months. Further studies into the pathophysiological mechanisms underlying this observation are warranted.

Abstract
The risk of cardiovascular disease in elderly is significantly higher than in young subjects; paradoxically some treatments that have proven their efficacy in reducing cardiovascular risk are often under prescribed in this age group. The benefits of statins in secondary cardiovascular prevention are well established in patients <80 years. In primary prevention, these drugs reduce the risk of myocardial infarction and stroke, but their effects on cardiovascular mortality remain uncertain. In very elderly patients, there are no randomized trials relative to the impact of statins on morbi-mortality in primary prevention as well in secondary prevention. Adverse effects in the elderly seem to be statistically similar to those occurring in young people , but the prescription in very old people should be individualized, taking into account the life expectancy, the life quality, the comorbidities, and especially the risk of drug interactions.

Hong KS, Lee JS. Statins in Acute Ischemic Stroke: A Systematic Review. J Stroke 2015; 17:282-301. [PMID: 26437994 PMCID: PMC4635713 DOI: 10.5853/jos.2015.17.3.282] [Citation(s) in RCA: 103] [Impact Index Per Article: 11.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2015] [Revised: 04/02/2015] [Accepted: 04/04/2015] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND AND PURPOSE Statins have pleiotropic effects of potential neuroprotection. However, because of lack of large randomized clinical trials, current guidelines do not provide specific recommendations on statin initiation in acute ischemic stroke (AIS). The current study aims to systematically review the statin effect in AIS. METHODS From literature review, we identified articles exploring prestroke and immediate post-stroke statin effect on imaging surrogate markers, initial stroke severity, functional outcome, and short-term mortality in human AIS. We summarized descriptive overview. In addition, for subjects with available data from publications, we conducted meta-analysis to provide pooled estimates. RESULTS In total, we identified 70 relevant articles including 6 meta-analyses. Surrogate imaging marker studies suggested that statin might enhance collaterals and reperfusion. Our updated meta-analysis indicated that prestroke statin use was associated with milder initial stroke severity (odds ratio [OR] [95% confidence interval], 1.24 [1.05-1.48]; P=0.013), good functional outcome (1.50 [1.29-1.75]; P<0.001), and lower mortality (0.42 [0.21-0.82]; P=0.0108). In-hospital statin use was associated with good functional outcome (1.31 [1.12-1.53]; P=0.001), and lower mortality (0.41 [0.29-0.58]; P<0.001). In contrast, statin withdrawal was associated with poor functional outcome (1.83 [1.01-3.30]; P=0.045). In patients treated with thrombolysis, statin was associated with good functional outcome (1.44 [1.10-1.89]; P=0.001), despite an increased risk of symptomatic hemorrhagic transformation (1.63 [1.04-2.56]; P=0.035). CONCLUSIONS The current study findings support the use of statin in AIS. However, the findings were mostly driven by observational studies at risk of bias, and thereby large randomized clinical trials would provide confirmatory evidence.

Comparative effects of more versus less aggressive treatment with statins on the long-term outcome of patients with acute ischemic stroke. Atherosclerosis 2015; 243:65-70. [PMID: 26355807 DOI: 10.1016/j.atherosclerosis.2015.08.043] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/28/2015] [Revised: 08/24/2015] [Accepted: 08/31/2015] [Indexed: 11/20/2022]
Abstract
BACKGROUND AND AIMS There are no studies that compared the effects of different intensities of statin treatment on the long-term outcome of patients with recent ischemic stroke. We aimed to evaluate these effects. METHODS We prospectively studied 436 consecutive patients who were discharged after acute ischemic stroke (39.2% males, age 78.6 ± 6.7 years). Statin treatment was categorized in equipotent doses of atorvastatin. One year after discharge, the functional status was assessed with the modified Rankin scale (mRS). Adverse outcome was defined as mRS between 2 and 6. The occurrence of ischemic stroke, myocardial infarction and death was recorded. RESULT Adverse outcome rates were lower in patients treated with atorvastatin 20 mg/day or more potent doses of statins than in patients treated with atorvastatin 10 mg/day (63.5, 38.2 and 48.2%, respectively; p = 0.004). In binary logistic regression analysis, independent predictors of adverse outcome were the mRS at discharge (relative risk (RR) 2.33, 95% confidence interval (CI) 1.77-3.07, p < 0.001) whereas more aggressive treatment with statins independently predicted favorable outcome (atorvastatin 20 vs. 10 mg/day, RR 0.30, 95% CI 0.11-0.87, p = 0.026; atorvastatin 40 mg/day or more potent dose of statins vs. atorvastatin 10 mg/day, RR 1.66, 95% CI 0.62-4.44, p = NS). The incidence of cardiovascular events and all-cause mortality showed a trend for being lower in patients treated with atorvastatin 40-80 mg/day or rosuvastatin 10-40 mg/day than in those treated with less potent doses of statins. CONCLUSION More aggressive statin treatment improves the long-term functional outcome of patients with acute ischemic stroke more than less aggressive treatment.

Abstract
BACKGROUND There are numerous potential treatments assessed for acute cerebral ischemia using animal models. This study aimed to assess the effect of these treatments in terms of infarct size and neurobehavioral change. This meta-analysis was conducted to determine if any of these treatments provide a superior benefit so that they might be used on humans. METHODS A systematic search was conducted using several electronic databases for controlled animal studies using only nonsurgical interventions for acute cerebral ischemia. A random-effects model was used. RESULTS After an extensive literature search, 145 studies were included in the analysis. These studies included 1408 treated animals and 1362 control animals. Treatments that had the most significant effect on neurobehavioral scales included insulin, various antagonists, including N-methyl-D-aspartate (NMDA) receptor antagonist ACEA1021, calmodulin antagonist DY-9760e, and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor antagonist YM872, and antiviral agents. Treatments providing the greatest effect on infarct size included statins, sphingosine-1-phosphate agonist (fingolimod), alcohol, angiotensin, and leukotrienes. Treatments offering the greatest reduction in brain water content included various agonists, including sphingosine-1-phosphate agonist fingolimod, statins, and peroxisome proliferator-activated receptor gamma (PPAR-γ). Treatment groups with more than one study all had high heterogeneity (I2 > 80%), however, using meta-regression we determined several sources of heterogeneity including sample size of the treatment and control groups, the occlusion time, but not the year when the study was conducted. CONCLUSIONS Some treatments stand out when compared to others for acute cerebral ischemia in animals. Greater replication of treatment studies is required before any treatments are selected for future human trials.

Clinical factors associated with statins prescription in acute ischemic stroke patients: findings from the Lombardia Stroke Registry. BMC Neurol 2014; 14:53.

Abstract
BACKGROUND Statins, due to their well-established pleiotropic effects, have noteworthy benefits in stroke prevention. Despite this, a significant proportion of high-risk patients still do not receive the recommended therapeutic regimens, and many others discontinue treatment after being started on them. The causes of non-adherence to current guidelines are multifactorial, and depend on both physicians and patients. The aim of this study is to identify the factors influencing statin prescription at Stroke Unit (SU) discharge. METHODS This study included 12,750 patients enrolled on the web-based Lombardia Stroke Registry (LRS) from July 2009 to April 2012 and discharged alive, with a diagnosis of ischemic stroke or transient ischemic attack (TIA) and without contra-indication to statin therapy. By logistic regression analysis and classification trees, we evaluated the impact of demographic data, risk factors, tPA treatment, in-hospital procedures and complications on statin prescription rate at discharge. RESULTS We observed a slight increase in statins prescription during the study period (from 39.1 to 43.9%). Lower age, lower stroke severity and prestroke disability, the presence of atherothrombotic/lacunar risk factors, a diagnosis of non-cardioembolic stroke, tPA treatment, the absence of in-hospital complications, with the sole exception of hypertensive fits and hyperglycemia, were the patient-related predictors of adherence to guidelines by physicians. Overall, dyslipidemia appears as the leading factor, while TOAST classification does not reach statistical significance. CONCLUSIONS In our region, Lombardia, adherence to guidelines in statin prescription at Stroke Unit discharge is very different from international goals. The presence of dyslipidemia remains the main factor influencing statin prescription, while the presence of well-defined atherosclerotic etiopathogenesis of stroke does not enhance statin prescription. Some uncertainties about the risk/benefit of statin therapy in stroke etiology subtypes (cardioembolism, other or undetermined causes) may partially justify the underuse of statin in ischemic stroke. The differences that exist between current international guidelines may prevent a more widespread use of statin and should be clarified in a consensus.

Abstract
Pre-exposure to 3-hydroxy-3-methylgutaryl-coenzyne A reductase inhibitors (statins) appears to improve outcomes in patients with acute ischemic stroke (AIS). Whether this extends to patients over 80 is not known. Patients ≥80 years of age with AIS were retrospectively reviewed from the stroke registry of a tertiary stroke center. Pre-admission statin use, demographics, vascular risk factors, and comorbid conditions were assessed. Primary outcomes were admission National Institutes of Health Stroke Scale (NIHSS) scores and in-hospital mortality/discharge to hospice, and secondary outcomes included subsequent intracerebral hemorrhage (ICH) and modified Barthel index (mBI) at 3 months. Multivariable logistic regression was used to evaluate the association between pre-admission statin use and outcomes among elderly patients. Among 804 patients ≥80, those taking statins prior to AIS admission were overall younger, were more likely to have hypertension, coronary artery disease, diabetes, hyperlipidemia, and were more likely to be on an antiplatelet, but less likely to receive treatment with IV tissue plasminogen activator (tPA). Patients on statin had lower stroke severity (NIHSS>16: 21.9% vs. 27.6%) and in-hospital mortality/discharge to hospice (22.8% vs. 27.6%), but neither was significant. There was no difference in ICH (1.2% vs. 1.9%), and patients on statins had a non-significant trend toward less disability on mBI (27.5% vs. 35.7%). Pre-admission statin use did not show a statistical difference in either outcome, but it did show a trend toward lower stroke severity and improved short-term outcomes. In addition, our study suggests that statins may be safe in elderly stroke patients and may not increase the risk of ICH.
