Statins during Anticoagulation for Emergency Life-Threatening Venous Thromboembolism: A Review. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1240. [PMID: 39202521 PMCID: PMC11356097 DOI: 10.3390/medicina60081240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 06/18/2024] [Revised: 07/15/2024] [Accepted: 07/29/2024] [Indexed: 09/03/2024]
Abstract
Venous thromboembolism (VTE) is the leading cause of morbidity and death worldwide, after cancer and cardiovascular diseases. VTE is defined to include pulmonary embolism (PE) and/or deep vein thrombosis (DVT). Approximately 25% of PE patients experience sudden death as an initial symptom of VTE, and between 10% and 30% of patients die within the first month after diagnosis. Currently, the only drugs approved for the treatment of both acute and chronic VTE are vitamin K antagonists (VKAs) and direct oral anticoagulants (DOACs). However, their effectiveness is limited due to their associated risk of bleeding. Ideally, therapy should be able to treat VTE and limit the risk of VTE recurrence without increasing the risk of bleeding. Several studies have shown that the use of statins during anticoagulation for VTE reduces the risk of death and VTE recurrence. However, to date, there are conflicting data on the impact of statins during anticoagulation for VTE. A biological protective function of statins during anticoagulation has also been reported. Statins affect D-dimer levels; tissue factor (TF) gene expression; and VIII, VII, and Von Willebrand clotting factors-the major clotting factors they are able to affect. However, the usefulness of statins for the treatment and prevention of VTE is currently under debate, and they should not be substituted for guideline-recommended VTE prophylaxis or anticoagulation treatment. In this review of the literature, we illustrate the advances on this topic, including data on the role of statins in primary VTE prevention and secondary VTE prevention, related biological mechanisms, the risk of bleeding during their use, and their ability to reduce the risk of death.

Abstract
Prenatal alcohol exposure (PAE) impairs recovery from cerebrovascular ischemic stroke in adult rodents. Since the gut becomes dysbiotic following stroke, we assessed links between PAE and enteric portal inflammation. Adult control and PAE rat offspring received a unilateral endothelin-1-induced occlusion of the middle cerebral artery. Post-stroke behavioral disabilities and brain cytokines were assessed. Mesenteric adipose and liver transcriptomes were assessed from stroke-exposed and stroke-naive offspring. We identified, in the liver of stroke-naive animals, a moderate correlation between PAE and a gene network for inflammatory necroptosis. PAE inhibited the acute-phase brain inflammatory cytokine response to stroke. Post-stroke neurological function was correlated with an adipose gene network associated with B-lymphocyte differentiation and nuclear factor κB (NF-κB) signaling and with a liver pro-inflammatory gene network. Collectively, PAE inhibits brain inflammation but results in an inflammatory signature in enteric portal tissues after stroke, suggesting that PAE persistently and adversely impacts the gut-brain axis following adult-onset disease.

J Evid Based Med 2022; 15:373-384. [PMID: 36510635 DOI: 10.1111/jebm.12507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2022] [Accepted: 11/30/2022] [Indexed: 12/15/2022]
Abstract
AIMS Statins had been used as a cornerstone in the primary and secondary prevention of cardiovascular disease. Widespread attention had been given to the risk of bleeding, especially intracranial hemorrhage (ICH) in patients receiving statins therapy. This study aimed to determine whether statins treatment was associated with the risk of bleeding and ICH in randomized controlled trials (RCTs). MATERIALS AND METHODS Electronic databases were searched for studies up to September 8, 2022. Articles from RCTs were included in the meta-analysis if they reported the bleeding events associated with the treatment of statins or placebo/nonstatin treatment. The risk ratios (RR) of total bleeding and ICH were pooled from the number of patients with each outcome in the statins and control groups from the included studies. RESULTS Twenty-nine studies comprising 145,929 individuals (2437 incident bleeding cases) were included in the meta-analysis. After a median follow-up duration of 3.65 years, statins treatment was not associated with the risk of all bleeding (RR = 1.03, 95% CI 0.93-1.15). Furthermore, in 26 studies comprising 144,177 participants, after a median follow-up duration of 3.95 years, statins treatment was not associated with the risk of ICH (RR = 1.05, 95% CI 0.84-1.31). Although in the subgroup analysis with patients with prior stroke, statins treatment showed an increased risk of ICH (RR = 1.47, 95% CI 1.07-2.01), sensitivity analysis showed that the result was unstable, which may be mainly driven by the SPARCL study. CONCLUSIONS Statins therapy is not associated with the risk of all bleeding and ICH. Although a mildly increased risk of ICH in patients with prior stroke is observed, which may be caused by chance finding and warrant further documentation.

Abstract
PURPOSE For ischemic stroke patients, thrombolysis therapy combined statins might have a better benefit. But difference studies had a debate. The meta-analysis wants to make clear about whether statins could increase effect of therapy or decrease side effect for these patients. METHODS OBJECTIVES To evaluate the effect and safety about using statins in ischemic stroke patients receiving thrombolysis. DATA SOURCES Databases including PubMed, Web of Science, Embase and Cochrane Library. Eligibility criteria: original observational cohort studies. PARTICIPANTS ischemic stroke patients receiving thrombolysis. INTERVENTIONS pretreatment statins. Appraisal and synthesis methods: forest plot to show pooled results; I-squared test to evaluate the heterogeneity. RESULTS Of 87 selected, 8 were eligible. The 8 studies included 10,344 patients (with statins: 2048; without statins: 8296). For clinical recovery at 24 h, pooled OR (odds ratios) was 1.82 (95% CI: 1.49-2.21). For excellent outcome, pooled OR was 1.03 (95% CI: 0.80-1.12). For favorable outcome, pooled OR was 0.99 (95% CI: 0.85-1.16). For ICH (intracranial hemorrhage), pooled OR was 1.16 (95% CI: 0.97-1.40). For sICH (symptomatic intracranial hemorrhage), pooled OR was 1.40 (95% CI: 1.02-1.91). For mortality, overall pooled OR was 0.96 (95% CI: 0.74-1.25). CONCLUSION In conclusion, the meta-analysis found that for ischemic stroke patients receiving thrombolysis, pretreatment statins were related to a better clinical recovery and a lower short-term mortality. Pretreatment statins had no significant relationship with mRS at 90 days and ICH. Pretreatment high dose statins may be related to the occurrence of sICH.

Abstract
Stroke is the second most common cause of death worldwide. The rates of stroke are increasing in less affluent countries predominantly because of a high prevalence of modifiable risk factors. The Lipid Association of India (LAI) has provided a risk stratification algorithm for patients with ischaemic stroke and recommended low density lipoprotein cholesterol (LDL-C) goals for those in a very high risk group and extreme risk group (category A) of <50 mg/dl (1.3 mmol/l) while the LDL-C goal for extreme risk group (category B) is ≤30 mg/dl (0.8 mmol/l). High intensity statins are the first-line lipid lowering therapy. Non-statin therapy like ezetimibe and proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors may be added as an adjunct to statins in patients who do not achieve LDL-C goals statins alone. In acute ischaemic stroke, high intensity statin therapy improves neurological and functional outcomes regardless of thrombolytic therapy. Although conflicting data exist regarding increased risk of intracerebral haemorrhage (ICH) with statin use, the overall benefit risk ratio favors long-term statin therapy necessitating detailed discussion with the patient. Patients who have statins withdrawn while being on prior statin therapy at the time of acute ischaemic stroke have worse functional outcomes and increased mortality. LAI recommends that statins be continued in such patients. In patients presenting with ICH, statins should not be started in the acute phase but should be continued in patients who are already taking statins. ICH patients, once stable, need risk stratification for atherosclerotic cardiovascular disease (ASCVD).

Abstract
Background: The data on the relationship between statin use and clinical outcomes after intravenous thrombolysis (IVT) for acute ischemic stroke (AIS) are in controversy. Objective: This systematic review and meta-analysis aimed to evaluate the safety and efficacy of statins administered prior to onset and during hospitalization in patients with AIS treated with IVT. Methods: We searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials from inception until June 8, 2021. Comparative studies investigating statin effect on intracranial hemorrhage (ICH), functional outcomes, and mortality in adults with AIS treated with IVT were screened. Random-effect meta-analyses of odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were performed. The protocol was registered in PROSPERO (CRD42021254919). Results: Twenty-two observational studies were included, which involved 17,554 patients. The pooled estimates showed that pre-stroke statin use was associated with a higher likelihood of symptomatic ICH (OR 1.31; 95% CI 1.07–1.59; p = 0.008) and any ICH (OR 1.21; 95% CI 1.03–1.43; p = 0.02). However, the pre-stroke statin use was not significantly associated with the 3-month mortality, 3-month favorable functional outcome (FFO, modified Rankin Scale [mRS] score 0–1), and 3-month functional independence (FI; mRS score 0–2). However, in-hospital statin use was associated with a reduced risk of symptomatic ICH (OR 0.46; 95% CI 0.21–1.00; p = 0.045), any ICH (OR 0.51; 95% CI 0.27–0.98; p = 0.04), and 3-month mortality (OR 0.42; 95% CI 0.29–0.62; p < 0.001) and an increased probability of 3-month FFO (OR 1.33; 95% CI 1.02–1.744; p = 0.04) and 3-month FI (OR 1.41; 95% C, 1.11–1.80; p = 0.005). Conclusions: The present systematic review and meta-analysis suggests that in-hospital statin use after IVT may be safe and may have a favorable impact on clinical outcomes, a finding not observed in studies restricted to patients with pre-stroke statin use.

Core Results and Subanalyses on the Effects of Ezetimibe Added to Statin Therapy Related to Age, Gender and Selected Chronic Diseases (Kidney Disease, Diabetes Mellitus and Non-Alcoholic Fatty Liver Disease). Curr Vasc Pharmacol 2021; 19:451-468. [DOI: 10.2174/1570161118999200727224946] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2020] [Revised: 06/23/2020] [Accepted: 07/03/2020] [Indexed: 11/22/2022]
Abstract
IMPROVE-IT (IMProved Reduction of Outcomes: Vytorin Efficacy International Trial) was
a randomized clinical trial (including 18,144 patients) that evaluated the efficacy of the combination of
ezetimibe with simvastatin vs. simvastatin monotherapy in patients with acute coronary syndrome
(ACS) and moderately increased low-density lipoprotein cholesterol (LDL-C) levels (of up to 2.6-3.2
mmol/L; 100-120 mg/dL). After 7 years of follow-up, combination therapy resulted in an additional
LDL-C decrease [to 1.8 mmol/L, or 70 mg/dL, within the simvastatin (40 mg/day) monotherapy arm
and to 1.4 mmol/L, or 53 mg/dL for simvastatin (40 mg/day) + ezetimibe (10 mg/day)] and showed an
incremental clinical benefit [composite of cardiovascular death, nonfatal myocardial infarction, unstable
angina requiring rehospitalization, coronary revascularization (≥30 days after randomization), or nonfatal
stroke; hazard ratio (HR) of 0.936, and 95% CI 0.887-0.996, p=0.016]. Therefore, for very high cardiovascular
risk patients “even lower is even better” regarding LDL-C, independently of the LDL-C
reducing strategy. These findings confirm ezetimibe as an option to treat very-high-risk patients who
cannot achieve LDL-C targets with statin monotherapy. Additional analyses of the IMPROVE-IT (both
prespecified and post-hoc) include specific very-high-risk subgroups of patients (those with previous
acute events and/or coronary revascularization, older than 75 years, as well as patients with diabetes
mellitus, chronic kidney disease or non-alcoholic fatty liver disease). The data from IMPROVE-IT also
provide reassurance regarding longer-term safety and efficacy of the intensification of lipid-lowering
therapy in very-high-risk patients resulting in very low LDL-C levels. We comment on the results of
several (sub) analyses of IMPROVE-IT.

Abstract
Background: The association between the premorbid use of statin and the early outcomes of acute ischemic stroke (AIS) after intravenous thrombolysis (IVT) remains uncertain. We performed a meta-analysis of observational studies to evaluate the influence of the premorbid use of statin on functional outcome and symptomatic intracranial hemorrhage (SIH) in AIS after IVT. Methods: Relevant studies were identified by search of PubMed, Embase, and Cochrane's Library databases. Only studies with multivariate analyses were included. A random-effect model, incorporating inter-study heterogeneity, was used to pool the results. Results: Twenty observational studies with 20,752 AIS patients who were treated with IVT were included. The pooled results showed that the premorbid use of statin was not associated with improved 3-month favorable functional outcome [odds ratio (OR): 1.05, 95% confidence interval (CI): 0.87-1.26, p = 0.60, I 2 = 52%), 3-month functional independence (OR: 1.13, 95% CI: 0.96-1.33, p = 0.15, I 2 = 52%), or 3-month mortality (OR: 1.12, 95% CI: 0.94-1.34, p = 0.20, I 2 = 20%). Moreover, the premorbid use of statin was associated with an increased risk of SIH in AIS after IVT (OR: 1.48, 95% CI: 1.12-1.95, p = 0.006, I 2 = 60%). Subgroup analyses according to study design, adjustment of baseline low-density lipoprotein cholesterol, and definitions of SIH showed consistent results (p-values for subgroup difference all >0.05). Conclusions: The premorbid use of statin is not associated with improved functional outcomes or mortality but is associated with a higher risk of SIH in AIS patients after IVT.
