Cerebral amyloid angiopathy (CAA) is an increasingly recognized cause of cognitive decline and lobar intracerebral hemorrhage in older adults. Recent research highlights that neuropsychiatric symptoms (NPSs)—including depression, anxiety, apathy, and irritability—are highly prevalent in CAA, often emerging prior to overt cognitive impairment or major vascular events. Compared to other cerebrovascular diseases, CAA presents a distinctive and multifaceted NPS profile, with symptoms closely linked to disease severity and neuroimaging biomarkers such as white matter hyperintensities and microbleeds. Critically, NPSs in CAA can complicate cognitive assessment and predict worse functional outcomes, yet remain underappreciated in clinical and research contexts. Management is complicated by pharmacologic risks—including heightened bleeding risk associated with SSRIs and novel anti-amyloid therapies—underscoring the need for individualized and multidisciplinary approaches. We highlight the urgent need for standardized NPS assessment, targeted research into mechanisms and treatment, and greater integration of neuropsychiatric evaluation into CAA care. We suggest that recognizing NPSs as core clinical features—not secondary complications—of CAA is essential to improving both patient outcomes and scientific understanding. Future studies should focus on longitudinal analyses, the development of tailored interventions, and robust comparative research to clarify the pathophysiology, clinical trajectory, and optimal management of NPSs in CAA.

Background/Objectives: Tick-borne diseases (TBDs) are increasingly recognized as causes of both systemic and neurologic illness. While their impact on vascular health is established, their role in cerebrovascular disease remains underexplored. This review aims to synthesize clinical evidence linking TBDs with cerebrovascular events, focusing on mechanisms of injury, pathogen-specific associations, and treatment outcomes. Methods: A narrative review was conducted using Boolean keyword searches across PubMed, Scopus, EMBASE, and Web of Science. Relevant literature on ischemic and hemorrhagic stroke, cerebral vasculitis, and stroke mimics associated with TBDs was examined. The review included case reports, observational studies, and mechanistic research. Pathogen-specific data and disease characteristics were extracted and summarized. Results: Several tick-borne pathogens were associated with cerebrovascular complications. Borrelia burgdorferi was most commonly implicated and typically presented with large-vessel vasculitis. Rickettsia, Ehrlichia, and Anaplasma species caused endothelial injury through immune-mediated inflammation. Powassan virus and Crimean–Congo hemorrhagic fever virus exhibited central nervous system involvement and hemorrhagic potential. Babesia species contributed to vascular injury through thrombocytopenia and embolic complications. Neuroimaging frequently demonstrated multifocal stenoses and vessel wall inflammation. Antimicrobial treatment, particularly with doxycycline or ceftriaxone, was often effective, especially when administered early. Supportive care for stroke symptoms varied by presentation and underlying pathogen. Conclusions: Cerebrovascular disease caused by tick-borne pathogens is an underrecognized but potentially reversible condition. Despite diverse etiologies, most pathogens share a final common pathway of endothelial dysfunction. Early recognition and targeted antimicrobial therapy, combined with supportive stroke care, are essential to improving patient outcomes. Full article

Blood–brain barrier (BBB) deterioration with increasing age is an important factor contributing to vascular dementia. Previous studies show that endothelial nitric oxide synthase (eNOS) facilitates vascular endothelial growth factor-mediated angiogenesis and increased vascular permeability. In contrast, recent work has shown that aged hemi-deficient hemizygous eNOS^+/− mice manifest BBB disruption in association with increased incidence of thromboembolic events in the brain. To unravel whether eNOS contributes to or protects against hypoxia-induced cerebrovascular damage, we compared chronic mild hypoxia (CMH)-induced cerebrovascular angiogenic remodeling and BBB breakdown in aged (20 months old) eNOS^+/− and wild-type (WT) mice. This revealed that CMH strongly enhanced eNOS expression in cerebral blood vessels with much lower levels in eNOS^+/− mice. eNOS hemi-deficiency resulted in greater CMH-induced BBB disruption, but unexpectedly, had no effect on endothelial proliferation. eNOS^+/− mice also displayed enhanced endothelial expression of the endothelial activation markers MECA-32, VCAM-1, and β3 integrin in cerebral blood vessels, indicating greater vascular inflammation, and this correlated with increased levels of microglial activation and demyelination. Taken together, our results support the concept that eNOS plays an important protective function in the aged brain by suppressing endothelial activation and maintaining cerebrovascular health.

Background/Objectives: This cohort study aimed to elucidate the real-world treatment course of patients receiving low-dose olanzapine (<2.5 mg), to assess its efficacy, and to examine its metabolic side effects. This study was a cohort study using a clinical registry. Methods: The primary efficacy endpoint was effective medication adherence and appropriate dosing. The primary safety endpoint was the incidence of metabolic adverse events, including diabetes mellitus, dyslipidemia, cardiovascular events, and cerebrovascular events. Cox proportional hazards models were used to compare outcomes between groups. Results: A total of 9565 patients were prescribed olanzapine at Samsung Medical Center from 2002 to 2023, and 1629 (17%) were in the low-dose group. The median maintenance period for low-dose olanzapine was 142 days (IQR, 30–551 days), and 95.5% of patients received low-dose olanzapine with either gradual tapering or gradual dose escalation. During follow-up, the risk of diabetes mellitus (HR = 0.32, 95% CI = 0.17–0.62), dyslipidemia (HR = 0.59, 95% CI = 0.42–0.82), cardiovascular disease (HR = 0.88, 95% CI = 0.51–1.49), and cerebrovascular events (HR = 0.75, 95% CI = 0.41–1.36) was lower in the low-dose group than in the regular-dose group. Conclusions: Low doses of olanzapine have clinical benefits in providing appropriate dosing and a reduced incidence of metabolic side effects. These findings support personalized antipsychotic treatment strategies, particularly in populations with heightened metabolic vulnerability, by informing dose selection based on individual risk–benefit profiles.

Background: The optimal revascularization strategy for patients with left main coronary artery (LMCA) disease has been repeatedly addressed in randomized controlled trials (RCTs), although outcomes from real-life clinical studies are still poorly investigated. Objectives: This retrospective study aimed to assess the complete 5-year outcomes for individuals with multivessel coronary artery disease (MVD) involving LMCA disease treated with coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) as recommended by a local HT. Methods: From 2016 to 2019, 176 Heart Team (HT) meetings were held. Primary and secondary endpoints of 267 patients with MVD involving LMCA disease qualified either for CABG or PCI (109 and 158 patients, respectively) with subsequent optimal medical therapy (OMT) were assessed. The primary endpoint of the study was as an overall mortality, while secondary endpoints contained major adverse cardiac and cerebrovascular events (MACCE)—specifically, stroke, myocardial infarction (MI), repeat revascularization (RR), and the individual components of MACCE. Results: At 5 years, we found no significant difference in overall mortality between the both cohorts (22.9%-CABG vs. 24.7%-PCI, p = 0.74). The rate of MI was higher in patients treated percutaneously (7.3% vs. 15.8% for PCI, p = 0.04), while the incidence of stroke was higher in patients who underwent CABG (3.8% vs. 11.0% for CABG, p = 0.02). A MACCE occurrence was higher in PCI cohort (77.2% vs. 55.0%, p < 0.001), mainly driven by higher rates of RR was higher in patients treated percutaneously (32.9% vs. 13.8%, p < 0.001). Conclusions: For patients with LMCA disease, neither CABG nor PCI following HT decisions showed overwhelming superiority in real-life clinical practice: occurrence of all-cause death was similar, rates of MACCE, MI, and repeat revascularization advocated CABG, while incidence of strokes favored PCI.

Introduction: Previous studies have reported sex differences in stroke. There are few Asian studies. This study was performed to investigate sex differences in stroke risk factors and mechanisms in a multi-ethnic Asian population. Methods: Data on patients admitted to Raffles Hospital for stroke were analysed. Data were extracted on sex, age, hypertension, diabetes mellitus (DM), hyperlipidaemia, smoking, heart disease, and prior cerebrovascular events (pCeVD). Stroke was subtyped into haemorrhagic stroke (HS) or ischaemic stroke (IS) based on brain scan. IS mechanism was categorised using Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification, while the clinical syndrome by Oxfordshire Community Stroke Project (OCSP) classification. Results: Data were collected on 1165 patients, mean age 65.6 ± 12.9 yr; 47.4% female, 83.0% Chinese, with hypertension (63.5%) and hyperlipidaemia (60.3%) being the most common risk factors. HS comprised 23.5%. On regression analysis, compared to males, females had older age (OR 1.03, 95%CI 1.02–10.4) and DM (OR 1.60, 95%CI 1.11–2.30), but less smoking (OR 0.09, 95%CI 0.07–0.13), pCeVD (OR 0.67, 95%CI 0.49–0.93), and HS (OR 0.71, 95%CI 0.51–0.98). There were no differences in HS mechanisms, or IS mechanisms or syndromes. Sex–ethnic differences were found (p < 0.001), with more Chinese and fewer Indians among females compared to males. Conclusions: This study corroborates previous studies of significantly older age and more diabetes mellitus, but less smoking and haemorrhagic stroke among female stroke patients compared to males; differences in HS and IS mechanisms were not found. Novel in this study is that sex–ethnicity differences were found. Future studies should prospectively validate these sex/ethnic differences. Full article

Tumor necrosis factor (TNF) receptor-associated factor 7 (TRAF7) is a signal transducer in the TNF receptor superfamily. TRAF7 is unique among its superfamily in that it does not contain a TRAF-C domain but does contain WD-40 domains. TRAF7 interacts with mitogen-activated protein kinases (MAPK), which are known regulators of inflammation and shear stress response. Notably, these molecular interactions have profound implications for the function of brain endothelial cells (ECs), which are pivotal for sustaining the integrity of the blood–brain barrier (BBB), orchestrating neurovascular coupling (NVC), and modulating the vascular architecture. By directly influencing MAPK signaling pathways, particularly the shear stress-responsive MAPK kinase kinase 3 (MEKK3)–MAPK kinase 5 (MEK5)–extracellular-regulated protein kinase 5 (ERK5) cascade, TRAF7 contributes to vascular homeostasis, as exemplified by its role in phosphorylating ERK5. Such molecular events underpin the capacity of brain ECs to regulate substance exchange, adjust blood flow in response to neural activity, and maintain efficient cerebral perfusion, all of which are essential for preserving brain health and cognitive performance. By synthesizing the current evidence regarding TRAF7’s molecular functions and its impact on brain endothelial integrity, cerebrovascular aging, and exploring implications for therapeutic strategies targeting vascular dysfunction in the aging brain, this review fills a crucial gap in the literature. Given the limited number of original studies directly addressing these contexts, the review will integrate broader insights from related literature to provide a foundational overview for future research in this developing field. The culmination of this literature will provide a rationale for the development of novel TRAF7-targeted therapies to restore vascular integrity in the context of aging, which could maintain cognitive health. Although TRAF7 has been implicated in regulating endothelial permeability during inflammation, its precise functions in brain ECs and the subsequent effects on cerebrovascular structure and cognitive function remain to be fully elucidated.

Background/Objectives: Inflammation plays a key role in acute coronary syndromes (ACS). The systemic immune-inflammation index (SII), which integrates immune and inflammatory markers, may serve as a valuable prognostic tool. This study aimed to evaluate the utility of SII as a short-term predictor of mortality and major adverse cardiovascular and cerebral events (MACCE) in ACS patients. Methods: A retrospective analysis was conducted on 964 ACS patients admitted in 2023. SII was calculated from admission hematological parameters. Primary and secondary outcomes were 30-day mortality and MACCE, respectively. Results: SII levels differed significantly across ACS subtypes (p < 0.001), highest in ST-segment elevation myocardial infarction (STEMI) and lowest in unstable angina. SII was markedly higher in deceased patients (2003.79 ± 1601.17) vs. survivors (722.04 ± 837.25; p < 0.001) and remained an independent predictor of mortality (OR = 1.038, p < 0.001). Similarly, SII was elevated in MACCE cases (1717 ± 1611.32) vs. non-MACCE (664.68 ± 713.11; p < 0.001) and remained predictive in multivariate analysis (OR = 1.080, p < 0.001). Predictive accuracy for MACCE was moderate (AUC = 0.762), improved when combined with GRACE 2, especially in specificity (p = 0.07). In STEMI, SII had excellent accuracy (AUC = 0.874), outperforming neutrophil–lymphocyte ratio and C-reactive protein. SII rose at 24 h and declined at 48 h in STEMI, with a slower decline in MACCE patients. Conclusions: SII proved to be a cost-effective biomarker reflecting inflammation, immunity, and thrombosis. Elevated SII predicted short-term MACCE and mortality in ACS, with improved prognostic power when combined with GRACE 2. Persistent elevation may signal ongoing inflammation and increased MACCE risk.

Sleep disorders and stroke are intricately linked through a complex, bidirectional relationship. Sleep disturbances such as obstructive sleep apnea (OSA), insomnia, and restless legs syndrome (RLS) not only increase the risk of stroke but also frequently emerge as consequences of cerebrovascular events. OSA, in particular, is associated with a two- to three-fold increased risk of incident stroke, primarily through mechanisms involving intermittent hypoxia, systemic inflammation, endothelial dysfunction, and autonomic dysregulation. Conversely, stroke can disrupt sleep architecture and trigger or exacerbate sleep disorders, including insomnia, hypersomnia, circadian rhythm disturbances, and breathing-related sleep disorders. These post-stroke sleep disturbances are common and significantly impair rehabilitation, cognitive recovery, and quality of life, yet they remain underdiagnosed and undertreated. Early identification and management of sleep disorders in stroke patients are essential to optimize recovery and reduce the risk of recurrence. Therapeutic strategies include lifestyle modifications, pharmacological treatments, medical devices such as continuous positive airway pressure (CPAP), and emerging alternatives for CPAP-intolerant individuals. Despite growing awareness, significant knowledge gaps persist, particularly regarding non-OSA sleep disorders and their impact on stroke outcomes. Improved diagnostic tools, broader screening protocols, and greater integration of sleep assessments into stroke care are urgently needed. This narrative review synthesizes current evidence on the interplay between sleep and stroke, emphasizing the importance of personalized, multidisciplinary approaches to diagnosis and treatment. Advancing research in this field holds promise for reducing the global burden of stroke and improving long-term outcomes through targeted sleep interventions. Full article

Background: Clinical outcomes among older adults hospitalized with heart failure with preserved ejection fraction (HFpEF) in the setting of metabolically healthy obesity (MHO) remain insufficiently explored. This study aimed to evaluate whether MHO status is associated with different rates of major adverse cardiac and cerebrovascular events (MACCEs) during HFpEF-related hospitalizations compared to patients without MHO. Methods: Data from the 2019 National Inpatient Sample (NIS) database was analyzed using relevant ICD-10 codes to identify HFpEF admissions in older adults. Propensity score matching (1:1) was applied to generate balanced cohorts of patients with and without MHO. Multivariable adjustments were performed to assess primary outcomes, including MACCEs, all-cause mortality (ACM), acute myocardial infarction (AMI), dysrhythmia, cardiac arrest (CA), and stroke. Statistical significance was set at p < 0.05. Results: Each MHO cohort included 22,405 patients with a median age of 75 years. The MHO+ group demonstrated a significantly higher risk of dysrhythmia (OR 1.32, 95% CI 1.21–1.43, p < 0.001). Interestingly, an “obesity paradox” was observed, as the MHO+ cohort had lower odds of MACCEs (OR 0.70, 95% CI 0.61–0.81, p < 0.001), ACM (OR 0.66, 95% CI 0.54–0.82, p < 0.001), and AMI (OR 0.71, 95% CI 0.59–0.86, p = 0.001) compared to MHO−. No significant differences were found for CA or stroke between the groups. Conclusions: Although the MHO+ group had an elevated risk of dysrhythmia, they exhibited more favorable outcomes in terms of MACCEs, ACM, and AMI—supporting the concept of an “obesity paradox.” Further research is needed to better understand the role of MHO as a comorbid condition in patients with HFpEF.

Background: Coronary heart disease (CHD) remains the most prevalent pathology within the circulatory system. Among its chronic complications, ischemic mitral valve regurgitation (IMR) is observed in approximately 15% of patients with sustained myocardial ischemia. The presence of this complex valvular defect significantly increases both overall mortality and the incidence of adverse cardiovascular events. Notably, the presence of moderate to severe mitral regurgitation in patients undergoing surgical revascularization has been shown to double the risk of death. Despite the well-established etiology of IMR, data regarding the efficacy of surgical interventions and the determinants of postoperative outcomes remain inconclusive. Methods: The objective of the present study was to evaluate both early and long-term outcomes of surgical treatment of mitral regurgitation in patients undergoing coronary artery bypass grafting (CABG) due to ischemic heart disease. Particular attention was given to the influence of the severity of regurgitation, left ventricular ejection fraction (LVEF), and the dimensions of the left atrium (LA) and left ventricle (LV) on the postoperative prognosis. An additional aim was to identify preoperative risk factors associated with increased postoperative mortality and morbidity. A retrospective analysis was conducted on 421 patients diagnosed with ischemic mitral regurgitation who underwent concomitant mitral valve surgery and CABG. Exclusion criteria included emergent and urgent procedures as well as non-ischemic etiologies of mitral valve dysfunction. Results: The study cohort comprised 34.9% women and 65.1% men, with the mean age of 65.7 years (±7.57). A substantial proportion (76.7%) of patients were aged over 60 years. More than half (51.5%) presented with severe heart failure symptoms, classified as NYHA class III or IV, while over 70% were categorized as CCS class II or III. Among the surgical procedures performed, 344 patients underwent mitral valve repair, and 77 patients required mitral valve replacement. Additionally, 119 individuals underwent concomitant tricuspid valve repair. Short-term survival was significantly affected by the presence of hypertension, prior cerebrovascular events, and chronic kidney disease. In contrast, hypertension and chronic obstructive pulmonary disease were identified as significant predictors of adverse late-term outcomes. Conclusions: Interestingly, neither the preoperative severity of mitral regurgitation nor the echocardiographic measurements of LA and LV dimensions were found to significantly influence surgical outcomes. The perioperative risk, as assessed by the EuroSCORE II (average score: 10.0%), corresponded closely with observed mortality rates following mitral valve repair (9.9%) and replacement (10.4%). Notably, the need for concomitant tricuspid valve surgery was associated with an elevated mortality rate (12.4%). Furthermore, the preoperative echocardiographic evaluation of LA regurgitation severity, as well as LA and LV dimensions, did not exhibit a statistically significant impact on either early or long-term surgical outcomes. However, a reduced LVEF was correlated with increased long-term mortality. The presence of advanced clinical symptoms and the necessity for tricuspid valve repair were independently associated with a poorer late-term prognosis. Importantly, the annual mortality rate observed in the late-term follow-up of patients who underwent surgical treatment of ischemic mitral regurgitation was lower than rates reported in the literature for patients managed conservatively. The EuroSCORE II scale proved to be a reliable and precise tool in predicting surgical risk and outcomes in this patient population. Full article

Background/Objectives: Immature platelet fraction (IPF) and reticulated platelets (RPs) are biomarkers reflecting the youngest and most metabolically active platelets in circulation. RPs, a subset of immature platelets, contain residual RNA and have been associated with increased thrombotic potential. Elevated IPF levels indicate enhanced platelet production, commonly observed during elevated platelet turnover, such as in autoimmune reactions, consumption, and thrombotic events. This systematic review aims to evaluate the potential role of IPF and RPs in the context of cerebrovascular events, specifically ischemic and hemorrhagic stroke, as well as transient ischemic attacks (TIAs), and to assess their clinical utility in stroke monitoring and management. Methods: A comprehensive literature search was conducted in PubMed, Scopus, Cochrane Library, and Web of Science for studies published between 2000 and 2024, which focused on IPF and RPs in human subjects with cerebrovascular events. Results: Six studies met the inclusion criteria. Findings suggest that elevated levels of IPF and RP are associated with the acute and chronic phases of ischemic stroke and TIA and may reflect increased platelet turnover and thrombotic activity. Some evidence supports their role in predicting stroke severity, recurrence, and underlying etiology, although results are not yet consistent across all studies. Conclusions: IPF and RPs are emerging biomarkers with potential applications in acute ischemic stroke and risk stratification. While current evidence is promising, further research is needed to standardize measurement techniques and validate their routine use in clinical practice. Full article

Background/Objectives: Patients with peripheral artery disease (PAD) have a heightened risk of major adverse cardiovascular events (MACE), including myocardial infarction, stroke, and death. Despite this, limited progress has been made in identifying reliable biomarkers to prognosticate such outcomes. Circulating growth factors, known to influence endothelial function and the progression of atherosclerosis, may hold prognostic value in this context. The objective of this research was to evaluate a broad range of blood-based growth factors to investigate their potential as predictors of MACE in patients diagnosed with PAD. Methods: A total of 465 patients with PAD were enrolled in a prospective cohort study. Baseline plasma levels of five different growth factors were measured, and participants were monitored over a two-year period. The primary outcome was the occurrence of MACE within those two years. Comparative analysis of protein levels between patients who did and did not experience MACE was performed using the Mann–Whitney U test. To assess the individual prognostic significance of each protein for predicting MACE within two years, Cox proportional hazards regression was performed, adjusting for clinical and demographic factors including a history of coronary and cerebrovascular disease. Subgroup analysis was performed to assess the prognostic value of these proteins in females, who may be at higher risk of PAD-related adverse events. Net reclassification improvement (NRI), integrated discrimination improvement (IDI), and area under the receiver operating characteristic curve (AUROC) were calculated to assess the added value of significant biomarkers to model performance for predicting 2-year MACE when compared to using demographic/clinical features alone. Kaplan–Meier curves stratified by IGFBP-1 tertiles compared using log-rank tests and Cox proportional hazards analysis were used to assess 2-year MACE risk trajectory based on plasma protein levels. Results: The average participant age was 71 years (SD 10); 31.1% were female and 47.2% had diabetes. By the end of the two-year follow-up, 18.1% (n = 84) had experienced MACE. Of all proteins studied, only insulin-like growth factor-binding protein 1 (IGFBP-1) showed a significant elevation among patients who suffered MACE versus those who remained event-free (20.66 [SD 3.91] vs. 13.94 [SD 3.80] pg/mL; p = 0.012). IGFBP-1 remained a significant independent predictor of 2-year MACE occurrence in the multivariable Cox analysis (adjusted hazard ratio [HR] 1.57, 95% CI 1.21–1.97; p = 0.012). Subgroup analyses revealed that IGFBP-1 was significantly associated with 2-year MACE occurrence in both females (adjusted HR 1.52, 95% CI 1.16–1.97; p = 0.015) and males (adjusted HR 1.04, 95% CI 1.02–1.22; p = 0.045). Incorporating IGFBP-1 into the clinical risk prediction model significantly enhanced its predictive performance, with an increase in the AUROC from 0.73 (95% CI 0.71–0.75) to 0.79 (95% CI 0.77–0.81; p = 0.01), an NRI of 0.21 (95% CI 0.07–0.36; p = 0.014), and an IDI of 0.041 (95% CI 0.015–0.066; p = 0.008), highlighting the prognostic value of IGFBP-1. Kaplan–Meier analysis showed an increase in the cumulative incidence of 2-year MACE across IGFBP-1 tertiles. Patients in the highest IGFBP-1 tertile experienced a significantly higher event rate compared to those in the lowest tertile (log-rank p = 0.008). In the Cox proportional hazards analysis, the highest tertile of IGFBP-1 was associated with increased 2-year MACE risk compared to the lowest tertile (adjusted HR 1.81; 95% CI: 1.31–2.65; p = 0.001). Conclusions: Among the growth factors analyzed, IGFBP-1 emerged as the sole biomarker independently linked to the development of MACE over a two-year span in both female and male PAD patients. The addition of IGFBP-1 to clinical features significantly improved model predictive performance for 2-year MACE. Measuring IGFBP-1 levels may enhance risk stratification and guide the intensity of therapeutic interventions and referrals to cardiovascular specialists, ultimately supporting more personalized and effective management strategies for patients with PAD to reduce systemic vascular risk.

Carotid stenosis is a common pathology in clinical practice and unfortunately carries a high risk of serious cerebrovascular events. The early recognition of carotid plaque and, consequently, a careful analysis by means of multimodal imaging are the necessary steps to undertake a correct management pathway, aimed at preventing or, if not possible, reducing the risk of atherogenic phenomena responsible for cerebral infarction. In particular, the presence or absence of clinical symptoms, understood as the occurrence of events such as TIAs in the last 6 months, non-disabling strokes or repeated episodes of amaurosis fugax, and the degree of carotid stenosis, are certainly the most studied parameters, and as reported by several international guidelines, can lead to the best therapeutic strategy: whether to rely on conservative medical therapy or to resort to mechanical revascularization of the carotid stenosis. According to the recommendations of the European Society of Vascular Surgery, mechanical revascularization is recommended for stenosis > 50% in symptomatic patients and stenosis > 60% in asymptomatic patients. In contrast, the latest findings on plaque vulnerability have focused attention on individual patient characteristics and clinical comorbidities that may be responsible for plaque inflammation and should therefore be taken into consideration to decide if revascularization treatment is needed even in those subjects who present stenosis with less degree than reported as critical value. Moreover, further radiological investigations are fundamental to finding the presence of entities such as plaque ulceration, plaque neo-vascularization, fibrous caps, and intraplaque lipid core that are responsible for increased vulnerability. Medical therapy involves interventions aimed at eliminating cardiovascular risk factors by administering drugs that control the comorbidities responsible for worsening carotid stenosis. Recent studies are also evaluating the effectiveness of new plaque-modifying drugs or targeted anti-inflammatory agents in reducing the risk of plaque development and complications. Revascularization therapies, on the other hand, include surgery (CEA), the endovascular technique (CAS), and a new hybrid technique (TCAR): they are all valid alternatives for the treatment of carotid stenosis, each with specific technical difficulties, but on the whole with comparable safety profiles and risk rates of postoperative complications, although some recent emergencies have focused attention on possible short- and long-term gender-dependent outcome differences. The aim of this manuscript is to present the state of the art in the management of patients with carotid stenosis and to take a closer look at revascularization options. In our opinion, the choice of one strategy over another should therefore depend on gender, anatomical features of the patient, preoperative comorbidities, and last but not least, the experience of the center and the multidisciplinary team involved in the management of the patient.
