Ethoxyquin, a Lipid Peroxidation Inhibitor, Has Protective Effects against White Matter Lesions in a Mouse Model of Chronic Cerebral Hypoperfusion.

White matter lesions induced by chronic cerebral hypoperfusion can cause vascular dementia; however, no appropriate treatments are currently available for these diseases. In this study, we investigated lipid peroxidation, which has recently been pointed out to be associated with cerebrovascular disease and vascular dementia, as a therapeutic target for chronic cerebral hypoperfusion. We used ethoxyquin, a lipid-soluble antioxidant, in a neuronal cell line and mouse model of the disease. The cytoprotective effect of ethoxyquin on glutamate-stimulated HT-22 cells, a mouse hippocampal cell line, was comparable to that of a ferroptosis inhibitor. In addition, the administration of ethoxyquin to bilateral common carotid artery stenosis model mice suppressed white matter lesions, blood-brain barrier disruption, and glial cell activation. Taken together, we propose that the inhibition of lipid peroxidation may be a useful therapeutic approach for chronic cerebrovascular disease and the resulting white matter lesions.

Role of glucagon-like peptide-1 receptor agonists in the treatment of obesity, cardiovascular disease, and cerebrovascular disease.

Worldwide prevalence of obesity is increasing dramatically, imposing a significant economic burden on our society. Treatment of obesity is challenging, potentially due to different disease phenotypes. Taking into consideration "obesities" rather than "obesity," and thus aiming to understand different pathophysiologic mechanisms of individual phenotypes, might help identify more tailored treatment strategies. Glucagon­like peptide­1 receptor agonists (GLP­1RAs), for example, dulaglutide and semaglutide, are routinely prescribed for the treatment of type 2 diabetes mellitus (T2DM) in patients with obesity or those at a high cardiovascular (CV) risk. Indeed, despite having been developed for T2DM, GLP­1RAs are being increasingly often recognized as antiobesity medications due to their weight loss effects. Furthermore, recent evidence has shown that the extent of CV prevention offered by these drugs goes beyond that associated with their weight loss and pleiotropic effects. For instance, they exert anti­inflammatory effects on vessels, enhance atherosclerotic plaque stability, reduce local advanced glycation end product receptor expression, lower monocyte­macrophage adhesion, and antagonize the effect of angiotensin II. In the heart, GLP­1RAs ameliorate cardiomyocyte survival and myocardial contractility, reduce cardiac hypertrophy, and are one of few drugs that can reduce epicardial fat thickness. In this review, we summarize recent evidence concerning the effects of GLP­1RAs on obesity / dysmetabolism and on cardio- / cerebrovascular health. We further highlight the possible role of GLP­1RAs in the treatment of obesity­related CV diseases by describing the principal molecular mechanisms reported in the current literature.

Protective mechanism of Paeonol on central nervous system.

Cerebrovascular diseases involve neuronal damage, resulting in degenerative neuropathy and posing a serious threat to human health. The discovery of effective drug components from natural plants and the study of their mechanism are a research idea different from chemical synthetic medicines. Paeonol is the main active component of traditional Chinese medicine Paeonia lactiflora Pall. It widely exists in many medicinal plants and has pharmacological effects such as anti-atherosclerosis, antiplatelet aggregation, anti-oxidation, and anti-inflammatory, which keeps generally used in the treatment of cardiovascular and cerebrovascular diseases. Based on the therapeutic effects of Paeonol for cardiovascular and cerebrovascular diseases, this article reviewed the pharmacological effects of Paeonol in Alzheimer's disease, Parkinson's disease, stroke, epilepsy, diabetes encephalopathy, and other neurological diseases, providing a reference for the research of the mechanism of Paeonol in central nervous system diseases.

[Features of pharmacotherapy of vascular cognitive impairment in the elderly]. / Osobennosti farmakoterapii sosudistykh kognitivnykh narushenii u lits pozhilogo vozrasta.

The problem of pharmacotherapy of elderly and senile people is currently extremely relevant due to the aging of the population and the increase in the prevalence of cardiovascular diseases. One of the most serious problems of the elderly is the development of cognitive decline due to cerebrovascular pathology. However, elderly patients often have a large number of comorbid diseases, which leads to difficulties in diagnosing and managing these patients, and often to the development of polypharmacy, which can lead to deterioration in functional status, cognitive impairment, adverse reactions and drug interactions. In addition, in elderly patients, there may be changes in pharmacokinetics and pharmacodynamics due to anatomical and physiological involutive processes. At the same time, the number of drugs whose clinical efficacy and tolerability were evaluated specifically in elderly and senile patients is relatively small. In a randomized clinical trial of sequential parenteral and oral therapy with Mexidol in patients with mild vascular cognitive impairment syndrome, a positive effect of this therapy on various domains (cognitive, emotional, autonomic, motor) of chronic cerebrovascular disease was confirmed compared with placebo, which allows us to recommend it for use in elderly and senile patients.

[Risk factors and adherence to treatment of patients with cerebrovascular diseases]. / Faktory riska i priverzhennost' lecheniyu patsientov s tserebrovaskulyarnymi zabolevaniyami.

OBJECTIVE: To assess the representation of risk factors and treatment adherence in patients with cerebrovascular diseases. MATERIAL AND METHODS: A single-stage cross-sectional non-comparable study was conducted, which included 492 patients, of whom 133 had an ischemic stroke/transient ischemic attack (main group, MG), 344 had chronic cerebrovascular pathology (comparison group, CG). The representation of risk factors, the state of cognitive functions, the severity of anxiety and depression were evaluated. RESULTS: MG respondents visit specialized specialists more often than CG (p<0.001), are more committed to taking antiplatelet agents (p<0.003), statins (p<0.005), antihypertensive drugs (p<0.005). Regular intake of antithrombotic drugs was associated with the history of ischemic stroke (r=0.483; p<0.01), type 2 diabetes (r=0.637; p<0.011), atrial fibrillation (r=0.481; p<0.001), living in a family (r=0.493; p<0.03). An inverse correlation was established between the systematic intake of antiplatelet drugs and the age of the respondents (r=-0.637; p<0.002), cognitive impairment (r=-0.433; p<0.05), the history of the gastrointestinal tract diseases (gastric ulcer and duodenal ulcer) (r=-0.563; p<0.001). Irregular medication intake was observed in patients aged over 60 years compared with younger (17.3% and 6.4%, respectively, p=0.001), patients living in a family compared with single (85.6% and 65.1%, p=0.032). The history of ischemic stroke or myocardial infarction is associated with increased adherence to regular medication. CONCLUSION: The study of risk factors and the assessment of treatment adherence can ensure the formation of an effective strategy for primary and secondary prevention of cerebrovascular diseases.

Genotype-guided dual antiplatelet therapy in cerebrovascular disease: assessing the risk and benefits for ethnic populations.

INTRODUCTION: Cerebrovascular disease is a leading cause of morbidity and mortality in the world and antiplatelet therapy is a main pharmacologic means of secondary prevention. Clinical information has accumulated about benefit of dual antiplatelet therapy in certain clinical scenarios, genetic causes of antiplatelet resistance and its effect on clinical outcomes, and ethnic and geographic distributions of genetic polymorphisms. AREAS COVERED: This review covers literature related to the pharmacogenomics of antiplatelet agents with a focus on ethnic variability, antiplatelet resistance, and dual antiplatelet therapy in cerebrovascular disease. EXPERT OPINION: Selecting patients for dual antiplatelet therapy and specific agents require consideration of multiple factors. Ethnic factors should be considered in certain circumstances, but additional research is needed to determine the generalizability of the findings.

Association Between Migraine and Ischemic Cardio-Cerebrovascular Disease (CCVD) and Effects of Triptans and Ergotamine on the Risk of Ischemic CCVD in Patients with Migraine in the Korean NHIS-HEALS Cohort.

BACKGROUND AND OBJECTIVES: Triptans and ergotamine are commonly used to treat migraine, a risk factor for ischemic stroke. This study aimed to investigate the association between migraine and ischemic cardio-cerebrovascular disease (CCVD). Further analyses were performed to examine whether symptom-relieving treatment of migraine with triptans and ergotamine reduces ischemic CCVD in migraineurs. METHODS: Participants from the Korean NHIS-HEALS cohort database were divided into patients reporting headache without migraine (HA), migraineurs who received at least one prescription for triptans or ergotamine (TE), and migraineurs who were prescribed neither triptans nor ergotamine (NTNE). Ischemic CCVDs comprised ischemic cerebrovascular diseases and cardiovascular diseases. Using cox proportional hazards regression models, primary and secondary analysis for risk of ischemic CCVDs was compared. RESULTS: Among 62,272 patients diagnosed with migraine or HA, men with migraine or HA numbered 14,747 and 8935, respectively, while the numbers of women were 27,836 and 10,754, respectively. The median follow-up was 6.65 years. The overall incidence rate of CCVDs was 4728/38,590 (12.25%) in females and 3158/23,682 (13.33%) in males. Compared with the HA group, the hazard ratios (HRs) (95% CIs) of the TE and NTNE groups for ischemic CCVDs were 1.18 (1.01-1.39) and 1.39 (1.28-1.50), respectively, in males, and 1.22 (1.09-1.37) and 1.53 (1.42-1.65), respectively, in females, after full adjustment for confounding variables. Compared with the NTNE group, the HRs (95% CIs) of the TE group for ischemic CCVDs were 0.86 (0.73-0.999) in males and 0.80 (0.72-0.88) in females. CONCLUSIONS: Migraine increased the risk of ischemic CCVDs in both sexes, and migraineurs treated with triptans and ergotamine were at lower risk of ischemic CCVDs than migraineurs who did not take those medications, especially in women.

[Efficacy of Mexidol in the correction of postcovid syndrome in patients with chronic cerebrovascular diseases]. / Effektivnost' preparata Meksidol v korrektsii postkovidnogo sindroma u patsientov s khronicheskimi tserebrovaskulyarnymi zabolevaniyami.

OBJECTIVE: To evaluate the effectiveness of sequential therapy with Mexidol and Mexidol FORTE 250 in the correction of postcovoid syndrome (PKS) in patients with chronic cerebrovascular diseases (CVD). MATERIAL AND METHODS: The analysis of the results of examination and treatment of 110 patients with CVD who underwent COVID-19 was carried out. Patients of the main group (OH, n=55) received Mexidol (5 ml IV drip for 14 days, followed by the transition to the tablet form of Mexidol FORTE 250 1 table 3 times/day for 2 months); 55 patients of the comparison group (GS) did not receive antioxidants. All patients included in the study were conducted MRI examination and extensive neuropsychological testing. RESULTS: There was a significant improvement in the state of cognitive functions, regression of symptoms of asthenia, improvement of night sleep in patients with OG. The differences were statistically significant both in comparison with the baseline level and the HS. CONCLUSION: The administration of the drug does not require age-related dose adjustment and is well combined with basic therapy. The recommended regimen for the use of Mexidol: 14 days of 5 ml i/v or i/m, then taking the drug Mexidol FORTE 250 at a dose of 1 table 3 times/day for 2 months.

VEGFA Isoforms as Pro-Angiogenic Therapeutics for Cerebrovascular Diseases.

Therapeutic angiogenesis has long been considered a viable treatment for vasculature disruptions, including cerebral vasculature diseases. One widely-discussed treatment method to increase angiogenesis is vascular endothelial growth factor (VEGF) A. In animal models, treatment with VEGFA proved beneficial, resulting in increased angiogenesis, increased neuronal density, and improved outcome. However, VEGFA administration in clinical trials has thus far failed to replicate the promising results seen in animal models. The lack of beneficial effects in humans and the difficulty in medicinal translation may be due in part to administration methods and VEGFA's ability to increase vascular permeability. One solution to mitigate the side effects of VEGFA may be found in the VEGFA isoforms. VEGFA is able to produce several different isoforms through alternative splicing. Each VEGFA isoform interacts differently with both the cellular components and the VEGF receptors. Because of the different biological effects elicited, VEGFA isoforms may hold promise as a tangible potential therapeutic for cerebrovascular diseases.

Disparities in PCSK9 Initiation Among US Veterans with Peripheral Arterial Disease or Cerebrovascular Disease.

BACKGROUND: Effective lipid lowering is essential in patients with peripheral arterial disease (PAD) and cerebrovascular disease (CeVD). Proprotein convertase subtilsin/kexin type 9 inhibitors (PCSK9i) efficiently lower low-density lipoprotein (LDL) levels; however, use in PAD and CeVD patients is limited. Therefore, our aim was to evaluate the use of PCSK9i among US Veterans and compare rates between patients with PAD, CeVD, and coronary artery disease (CAD). METHODS: We evaluated PCSK9i initiation (2016-2019) in US Veterans with CAD, PAD, or CeVD treated at 124 Veterans Affairs (VA) hospitals. We fit a hierarchical logistic regression model to evaluate the association of the patient's primary diagnosis, baseline low-density lipoprotein cholesterol (LDL-C) levels, socioeconomic indicators, and the Department of Veterans Affairs medical center enrollment with PCSK9i initiation. RESULTS: Of 519,566 patients with atherosclerotic vascular disease, 337,766 (65%), 79,926 (15%) and 101,874 (20%) had CAD, PAD, and CeVD, respectively. Among 2115/519,566 (0.4%) initiated on PCSK9i therapy, 84.3% had CAD, while only 7.2% and 8.5% had PAD and CeVD, respectively. Compared with CAD patients, PAD {odds ratio [OR] 0.50 (0.36-0.70)} and CeVD [OR 0.24 (0.15-0.37)] patients were less likely to receive PCSK9i. Relative to under $40K per year, PCSK9i initiation was higher if earning $40,000-$80,000 [OR 1.13 (1.01-1.27)] or > $80,000 [OR 1.41 (1.14-1.75)]. Even moderate community deprivation [OR 0.87 (0.77-0.97)] was associated with lower PCSK9i therapy. CONCLUSIONS: Adjusted for LDL-C levels, PAD and CeVD patients are much less likely to receive PCSK9i therapy. Despite low co-pay, PCSK9i initiation rates among US veterans, nationwide, is low, with household income and community deprivation appearing to predict PCSK9i use.

Comparison between clevidipine and nicardipine in cerebrovascular diseases: A systematic review and meta-analysis.

PURPOSE: The term "cerebrovascular diseases (CVDs)" refers to a broad category of diseases that affect the brain's blood vessels and cerebral circulation. Controlling acute hypertension (HTN) by antihypertensive drugs such as clevidipine and nicardipine can be a highly efficient method of lowering the incidence of CVDs. METHODS: This is a systematic review and meta-analysis study. The PubMed, Scopus, and Web of Science online databases and a gray literature search were performed to identify potentially eligible studies. The included studies were observational studies that compared adult patients receiving clevidipine or nicardipine for controlling HTN in the setting of CVD. RESULTS: We reviewed 5 final included articles, including 546 patients. The pooled standardized mean difference (SMD) for time to goal SBP was - 0.04 (95 % CI: [-0.66; 0.58], p-value: 0.86, I2: 79.0 %, pooled MD: -12.90 min), meaning that the clevidipine group had a shorter time to goal systolic blood pressure (SBP) than the nicardipine group. The pooled SMD for total volume infusion was - 0.52 (95 % CI: [-0.93; -0.12], p-value: 0.03, I2: 0.0 %, pooled MD: -1118.81 mL), showing a notably lower total volume infused into patients in the clevidipine group. CONCLUSIONS: We found that clevidipine reaches the SBP goal faster than nicardipine; however, there was no statistically significant difference between the two drugs. The total volume infused to achieve the goal SBP was significantly lower in the clevidipine group. Further prospective studies are needed to compare clevidipine and nicardipine in CVD patients on a large scale.

Xanthine oxidase mediates chronic stress-induced cerebrovascular dysfunction and cognitive impairment.

Xanthine oxidase (XO) mediates vascular function. Chronic stress impairs cerebrovascular function and increases the risk of stroke and cognitive decline. Our study determined the role of XO on stress-induced cerebrovascular dysfunction and cognitive decline. We measured middle cerebral artery (MCA) function, free radical formation, and working memory in 6-month-old C57BL/6 mice who underwent 8 weeks of control conditions or unpredictable chronic mild stress (UCMS) with or without febuxostat (50 mg/L), a XO inhibitor. UCMS mice had an impaired MCA dilation to acetylcholine vs. controls (p < 0.0001), and increased total free radical formation, XOR protein levels, and hydrogen peroxide production in the liver compared to controls. UCMS increased hydrogen peroxide production in the brain and cerebrovasculature compared to controls. Working memory, using the y-maze test, was impaired (p < 0.05) in UCMS mice compared to control mice. However, blocking XO using febuxostat prevented the UCMS-induced impaired MCA response, while free radical production and hydrogen peroxide levels were similar to controls in the liver and brain of UCMS mice treated with febuxostat. Further, UCMS + Feb mice did not have a significant reduction in working memory. These data suggest that the cerebrovascular dysfunction associated with chronic stress may be driven by XO, which leads to a reduction in working memory.

How low should blood pressure be in patients with chronic coronary and cerebrovascular diseases.

Over the last three decades, there are an increasing number of investigators and meta-analyses focusing on the fact that lowering blood pressure levels below a critical point is no longer beneficial and possibly even deleterious. In recent years, several trials and meta-analyses assessing intensive blood pressure (BP) lowering found that intensive treatment and lower blood pressure levels are associated with a reduction in CV events and mortality. However, a careful examination of the results shows that current data are not easily applicable to the general hypertensive population. In addition, recommendations of different guidelines since 2017 so far suggest different BP levels regarding the systolic and diastolic thresholds to be achieved and maintained, particularly in specific clinical situations such as patients with coronary artery disease and stroke. The challenge is to better define the limits of intervention and to define phenotypes of patients who are particularly vulnerable to over-aggressive lowering of blood pressure. This article reviews the evidence, controversies and current state of knowledge regarding intensive BP lowering and the lower thresholds of BP to be achieved in patients with chronic coronary or cerebrovascular diseases.

Vitamin D as therapeutic modulator in cerebrovascular diseases: a mechanistic perspectives.

Vitamin D deficiency has been linked to several major chronic diseases, such as cardiovascular and neurodegenerative diseases, diabetes, and cancer, linked to oxidative stress, inflammation, and aging. Vitamin D deficiency appears to be particularly harmful to the cardiovascular system, as it can cause endothelial dysfunctioning and vascular abnormalities through the modulation of various downstream mechanisms. As a result, new research indicates that therapeutic approaches targeting vitamin D inadequacies or its significant downstream effects, such as impaired autophagy, abnormal pro-inflammatory and pro-oxidant reactions, may delay the onset and severity of major cerebrovascular disorders such as stroke and neurologic malformations. Vitamin D modulates the various molecular pathways, i.e., Nitric Oxide, PI3K-Akt Pathway, cAMP pathway, NF-kB Pathway, Sirtuin 1, Nrf2, FOXO, in cerebrovascular disorder. The current review shows evidence for vitamin D's mitigating or slowing the progression of these cerebrovascular disorders, which are significant causes of disability and death worldwide.

Nanozyme-Enabled Treatment of Cardio- and Cerebrovascular Diseases.

Cardio- and cerebrovascular diseases are two major vascular-related diseases that lead to death worldwide. Reactive oxygen species (ROS) play a vital role in the occurrence and exacerbation of diseases. Excessive ROS induce cellular context damage and lead to tissue dysfunction. Nanozymes, as emerging enzyme mimics, offer a unique perspective for therapy through multifunctional activities, achieving essential results in the treatment of ROS-related cardio- and cerebrovascular diseases by directly scavenging excess ROS or regulating pathologically related molecules. This review first introduces nanozyme-enabled therapeutic mechanisms at the cellular level. Then, the therapies for several typical cardio- and cerebrovascular diseases with nanozymes are discussed, mainly including cardiovascular diseases, ischemia reperfusion injury, and neurological disorders. Finally, the challenges and outlooks for the application of nanozymes are also presented. This review will provide some instructive perspectives on nanozymes and promote the development of enzyme-mimicking strategies in cardio- and cerebrovascular disease therapy.

[Research progress in pharmacological effectsand mechanism of Fel Ursi against cardiovascular and cerebrovascular diseases].

Fel Ursi is a dried product obtained from the gallbladder of Ursidae animals, such as Selenarctos thibetanus or Ursus arctos, through gallbladder surgery for bile drainage. It is one of the rare animal medicinal materials in China and is known for its therapeutic effects, including clearing heat, removing toxins, extinguishing wind, relieving spasms, clearing the liver, and improving vision. Research has also found that Fel Ursi has pharmacological effects against cardiovascular and cerebrovascular diseases, such as anti-inflammatory, anti-apoptotic, and antioxidant stress properties. Recently, numerous studies have confirmed the close relationship between cardiovascular and cerebrovascular diseases and the gut microbiota as well as gut metabolites. Fel Ursi contains bile acid components that may have bidirectional regulatory effects on the gut microbiota and gut metabolites. This aspect could represent a potential therapeutic pathway for Fel Ursi in the treatment of cardiovascular and cerebrovascular diseases. This article comprehensively summarized relevant literature in China and abroad, reviewed the research progress on the pharmacological effects of Fel Ursi against cardiovascular and cerebrovascular diseases, and explored the impact of Fel Ursi on gut microbiota and gut metabolites, thereby aiming to provide references for further in-depth research and clinical application of Fel Ursi.

Relationship Between Calcium Channel Blockers Therapy and Cognitive Function Improvement in Cognitive Decline Patients with Cerebrovascular Disease.

INTRODUCTION: Amlodipine belongs to a class of calcium channel blockers that relax blood vessels to allow easier flow of blood. Higher blood pressure (BP) is associated with cerebrovascular disease and is an important contributor to cognitive decline and dementia. AIM: This study aimed to evaluate the effect of 24 weeks of S-amlodipine besylate therapy on cognitive function in patients with hypertension and cerebrovascular disease. METHODS: The data were obtained from a study of post-market surveillance of S-amlodipine besylate. RESULTS: A total of 545 subjects (mean age 67 ± 9.68 years) with hypertension and ischemic cerebrovascular disease were enrolled. Patients with a baseline Mini-Mental State Examination (MMSE) score above 26 were assigned to the cognitive normal (CN) (n = 294) group, and those with MMSE score less than 26 were in the cognitive decline (CD) (n = 251) group. After 24 weeks of treatment with S-amlodipine besylate 5 mg, MMSE and Global Deterioration Scale (GDS) were evaluated again. Changes in MMSE were compared in the target BP reached (TBPR) and non-reached (NTBPR) groups and for CN and CD groups. Treatment with 5 mg of S-amlodipine besylate for 24 weeks improved MMSE and GDS scores (p < 0.001). The CD group showed improvement in MMSE score regardless of whether target BP was obtained (TBPR: p < 0.001, NTBPR: p < 0.01). However, the CN classification was not significant for either TBPR or NTBPR groups. CONCLUSIONS: S-amlodipine besylate improved cognition of the CD group with hypertension and cerebrovascular disease regardless of obtaining target BP.

Insights into the Explicit Protective Activity of Herbals in Management of Neurodegenerative and Cerebrovascular Disorders.

The longstanding progressive neurodegenerative conditions of the central nervous system arise mainly due to deterioration, degradation and eventual neuronal cell loss. As an individual ages, the irreversible neurodegenerative disorders associated with aging also begin to develop, and these have become exceedingly prominent and pose a significant burden mentally, socially and economically on both the individual and their family. These disorders express several symptoms, such as tremors, dystonia, loss of cognitive functions, impairment of motor activity leading to immobility, loss of memory and many more which worsen with time. The treatment employed in management of these debilitating neurodegenerative disorders, such as Parkinson's disease (which mainly involves the loss of dopaminergic neurons in the nigrostriatal region), Alzheimer's disease (which arises due to accumulation of Tau proteins causing diffusive atrophy in the brain), Huntington's disease (which involves damage of striatal and spinal neurons, etc.), have several adverse effects, leading to exploration of several lead targets and molecules existing in herbal drugs. The current review highlights the mechanistic role of natural products in the treatment of several neurodegenerative and cerebrovascular diseases such as Parkinson's disease, Alzheimer's disease, ischemic stroke and depression.

Clinical Effect of Digital Subtraction Angiography Combined with Neurointerventional Thrombolysis for Acute Ischemic Cerebrovascular Disease and Its Influence on Vascular Endothelial Function and Oxidative Stress.

Objective: Ischemic cerebrovascular disease is a commonly seen vascular disorder in clinical practice. Given the difficulty of drug therapy to achieve ideal curative effects, interventional therapy has gradually become the preferred treatment for the disease. This research primarily discusses the short-term efficacy of digital subtraction angiography- (DSA-) guided neurointerventional thrombolysis for acute ischemic cerebrovascular disease (AICVD) and its influence on vascular endothelial function (VEF) and oxidative stress (OS). Methods: All the clinical data of 162 patients diagnosed with AICVD and treated between June 2019 and December 2021 were collected and analyzed retrospectively. They were assigned to two cohorts according to the difference in interventional methods: a conventional group (CG) given recombinant tissue plasminogen activator (rt-PA) therapy and an observation group (OG) intervened by DSA-guided neurointerventional thrombolysis. The two groups were compared with respect to short-term treatment efficacy, the National Institutes of Health Stroke Scale (NIHSS) score, cerebral hemodynamics, and VEF and OS indexes. Results: The short-term efficacy was better in OG (93.98%) than in CG (82.28%). After treatment, the NIHSS score decreased in both cohorts with obvious differences within the group at different time points, and the posttreatment NIHSS score was lower in OG as compared to CG. OG had higher Q m and V m while lower W v, Z cv, and R v than CG. Higher endothelial-dependent flow-mediated dilatation (FMD) was observed in OG, as well as lower ankle-brachial index (ABI) and pulse wave velocity (PWV). And the posttreatment MDA was lower while SOD, GSH-Px, and TAC were higher in OG compared with those on CG. All the above differences were of statistical significance (P < 0.05). Conclusions: DSA-guided neurointerventional thrombolysis is highly effective in the treatment of AICVD, which can not only effectively improve patients' neurological function and cerebral hemodynamics but also mitigate VEF injury and help to alleviate patients' OS.
