Statin Therapy in Ischemic Stroke Models: A Meta-Analysis

AbstractStatins, drugs known for lipid lowering capabilities and reduction of cardiovascular disease, have demonstrated neuroprotective effects following ischemic stroke in retrospective clinical and animal studies. However, dosing (methods, time, type of statin, and quantity) varies across studies, limiting the clinical applicability of these findings. Furthermore, a comprehensive review of statins in edema and blood-brain barrier (BBB) breakdown is needed to provide insight on diverse, less explored neuroprotective effects. In the present study, we conduct a meta-analysis of publications evaluating statin administration in animal models of ischemic stroke. We review statins ’ most effective dosing regimen in four outcomes—infarct, edema, BBB breakdown, and functional outcome—to characterize several parameters of benefit associated with statin administration. A search term was constructed to identify experimental murine studies exploring statin use after transient middle cerebral artery occlusion (tMCAO) in PubMed, Web of Science, and Embase. Extracted data included statin type, dose, time and method of administration, and the four predetermined outcomes (functional outcome, edema, BBB breakdown, and infarction). A meta-analysis and stratified meta-regressio n were conducted using the standardized mean difference (SMD) method for continuous measurements. Included publications were assessed for bias using SYRCLE’s RoB tool for animal studies. A total o...

This study assessed the safety and usefulness of pretreatment using a high-dose strong statin (HDSS) to reduce the periprocedural ischemic complications of CAS. We analyzed 117 carotid lesions treated by CAS that were evaluated with magnetic resonance imaging (MRI) within 48  h after the procedure. For 67 lesions, an HDSS (rosuvastatin 20 mg or atorvastatin 40 mg daily) were prescribed from at least 14 days before CAS to at least 14 days after procedure (HDSS group). Clinical and angiographic data, as well as in-hospital outcomes, of the HDSS group were retrospecti vely compared with 50 lesions wit...

AbstractPurpose of reviewHyperlipidemia is a key therapeutic target for stroke risk modification. The goal of this review is to highlight available treatment options and review their efficacy in the setting of general cardiovascular disease and after most subtypes of ischemic stroke and hemorrhagic stroke.Recent findingsStatins remain first-line in the management of hyperlipidemia to prevent stroke. In recent trials of patients with pre-existing atherosclerotic vascular disease, new agents, most notably PCSK9 inhibitors and ezetimibe, added additional stroke risk reduction when combined with statins.SummaryRisk of stroke c...

Authors: Chen Z, Jiang C, Qu H, Liang S, Yang J, Wu H, He C, Wang X Abstract Introduction: The aim of the current study was to evaluate the association between lipoprotein(a) [Lp(a)] and major adverse cardiovascular events (MACEs) in patients with percutaneous coronary intervention (PCI) treatment. Material and methods: This was a retrospective study. The demographics, prior medical histories, comorbidities and laboratory parameters were collected from the electronic health record. All participants were followed up for 1 year after the indexed PCI. Studied end points were a composite of MACEs including all-caus...

AbstractPurpose of ReviewTo review randomized interventional clinical and imaging trials that support lower targeted atherogenic lipoprotein cholesterol goals in “extreme” and “very high” atherosclerotic cardiovascular disease (ASCVD) risk settings. Major atherosclerotic cardiovascular event (MACE) prevention among the highest risk patients with ASCVD requires aggressive management of global risks, including lowering of the fundamental atherogenic ap olipoprotein B-associated lipoprotein cholesterol particles [i.e., triglyceride-rich lipoprotein remnant cholesterol, low-density lipoprotein cholester...

ConclusionBoth neurologic and medical complications were common in majority of stroke patients. But the management protocol for stroke patients was sub-optimal and lagging behind the recommended guidelines due to lack of skilled personnel, appropriate treatment and diagnostic agents. The clinical team involved in the care of stroke patients should make preparations to take preventive measures that will save a lot of lives.

The treatment options for stroke (thrombolysis or thrombectomy) are restricted to a small subset of patients with acute ischemic stroke because of the limited time for an efficacious response and the strict criteria applied to minimize the risk of cerebral hemorrhage. Attempts to develop new treatments, such as neuroprotectants, for acute ischemic stroke have been costly and tim...
