Introduction and background

Stroke remains a significant global health challenge, with ischemic stroke being the most common type of cerebrovascular disorder. It is primarily caused by arterial blockage, leading to significant neurological impairment and imposing a substantial burden on patients, families, and healthcare systems worldwide [1,2]. The global impact of stroke transcends geographic and socioeconomic boundaries, affecting millions annually and straining healthcare resources. Ischemic stroke accounts for the majority of cases, highlighting the urgency for effective prevention and management strategies [3]. Early detection and timely intervention remain critical for reducing mortality and improving recovery outcomes. Recent years have seen significant progress in diagnostic tools, therapeutic approaches, and rehabilitation strategies, reshaping the outlook for stroke patients [4-6].

Advances in diagnostic imaging, such as high-resolution magnetic resonance imaging (MRI) and computed tomography (CT) technologies, have improved the accuracy and speed of identifying ischemic strokes, enabling earlier intervention [7]. Novel biomarkers are enhancing the detection of at-risk patients and helping clinicians tailor treatments more effectively [8,9]. Mobile stroke units (MSUs) and telemedicine have emerged as transformative innovations in stroke care, significantly improving access to timely and specialized treatment, particularly in underserved and remote regions. MSUs are specialized ambulances equipped with advanced imaging technologies, such as portable CT scanners, and staffed by trained healthcare professionals, including neurologists and paramedics. These units enable rapid on-site diagnosis and the initiation of treatment, such as administering clot-busting drugs, long before the patient reaches the hospital. Similarly, telemedicine facilitates real-time consultation with stroke specialists through videoconferencing, allowing immediate guidance for diagnosis and treatment decisions in areas lacking access to neurologists [10]. These advancements embody the principle of "time is brain," a concept emphasizing that every moment counts during a stroke. In ischemic strokes, the brain is deprived of oxygen and nutrients due to a blocked artery, and as a result, approximately 1.9 million neurons are lost every minute without treatment. This rapid neuronal loss underscores the critical importance of minimizing delays in diagnosis and intervention to preserve brain function and improve patient outcomes. MSUs and telemedicine directly address these challenges by reducing pre-hospital delays, ensuring the faster delivery of evidence-based treatments, and improving survival rates and long-term recovery prospects [10,11].

Therapeutic advancements, including refinements in thrombolytic therapy and the expanding use of mechanical thrombectomy, have transformed acute stroke treatment. Extended treatment windows and improved techniques have increased the number of patients eligible for these life-saving interventions [11]. Furthermore, neuroprotective agents and anti-inflammatory therapies are under investigation, offering potential new avenues for treatment [11].

Post-stroke care has embraced personalized rehabilitation strategies, integrating multidisciplinary teams to address physical, cognitive, and emotional recovery. Tele-rehabilitation has emerged as a crucial tool, overcoming geographic barriers and providing continued care for stroke survivors. Patient-centric approaches now emphasize shared decision-making and caregiver involvement, improving overall outcomes and quality of life [9-11]. Emerging technologies such as artificial intelligence (AI) and machine learning hold promise for improving early risk prediction and intervention but require further validation in clinical settings [9-11]. The management of minor strokes and transient ischemic attacks also demands more attention, as these often signal larger vascular risks [11].

In summary, acute ischemic stroke management has entered a transformative era, driven by collaborative efforts across research, technology, and clinical practice. This review highlights the strides made while acknowledging the need for equitable access, ongoing innovation, and a patient-centered approach to care. The journey of stroke management continues, with promising developments on the horizon and a steadfast commitment to improving outcomes for those affected by this life-altering condition.

Developments in diagnosis and early management

Advanced Imaging Techniques

Advancements in imaging technologies over the past decade have significantly improved the early and precise diagnosis of acute ischemic stroke. Both MRI and CT, long-established diagnostic tools, have undergone substantial enhancements in resolution, speed, and functionality, greatly augmenting their utility in stroke management [12-16].

MRI has seen notable improvements in specialized imaging modalities, including high-resolution diffusion-weighted imaging (DWI), which facilitates the early and accurate detection of ischemic strokes by identifying restricted water diffusion in acute infarction areas. Perfusion-weighted imaging (PWI) now provides critical insights into cerebral blood flow, aiding in the identification of salvageable brain tissue (ischemic penumbra) and guiding therapeutic decisions. Susceptibility-weighted imaging (SWI) has advanced the detection of microvascular abnormalities and hemorrhagic transformations, essential for assessing treatment eligibility. Innovations like ultrafast MRI protocols have significantly reduced scan times, making MRI more accessible for emergency settings, while MR angiography (MRA) offers a detailed visualization of vascular occlusions, supporting mechanical thrombectomy planning. Additionally, AI integration has enabled the automated detection of ischemic lesions and enhanced real-time decision-making, further refining MRI's role in acute stroke care [12-14].

Similarly, CT imaging has advanced with improvements in resolution, speed, and functional capabilities. High-resolution CT angiography (CTA) now allows for the rapid identification of large vessel occlusions, crucial for determining eligibility for mechanical thrombectomy. CT perfusion (CTP) imaging provides detailed assessments of cerebral blood flow, cerebral blood volume, and time-to-peak perfusion, enabling the precise identification of the ischemic core and salvageable penumbra, even beyond conventional treatment windows. The adoption of whole-brain CTP techniques offers dynamic, volumetric imaging with unprecedented spatial and temporal resolution, enhancing diagnostic accuracy and supporting extended treatment opportunities. Additionally, ultra-low-dose CT protocols and iterative reconstruction algorithms have reduced radiation exposure while maintaining image quality, making CT imaging safer and more efficient for repeated use. AI integration in CT analysis has further enhanced the speed and accuracy of ischemic lesion detection and patient triage in hyperacute scenarios [12,13,15].

These advancements collectively demonstrate transformative progress in imaging technologies over the past decade, enabling timely interventions, expanding therapeutic opportunities, and ultimately improving patient outcomes in acute ischemic stroke management. By leveraging AI-driven workflows, dynamic imaging techniques, and rapid diagnostic capabilities, modern imaging tools have redefined the standards of stroke care, ensuring more effective and personalized management strategies.

Biomarkers: bridging diagnosis and prognosis

The pursuit of reliable biomarkers in ischemic stroke has evolved in tandem with advancements in imaging technologies. Brain natriuretic peptide (BNP) and glial fibrillary acidic protein (GFAP) have risen as prominent candidates in this field, offering the potential to revolutionize both the early diagnosis and prognostication of ischemic stroke [16-19].

BNP's journey from a marker primarily known for cardiovascular regulation to a significant indicator in neurology underscores its versatility. Its elevated levels post-acute ischemic events highlight a nuanced interplay between cardiac and cerebral health. BNP has shown moderate sensitivity (ranging from 65% to 85%) and specificity (from 60% to 80%) in identifying cardioembolic strokes compared to other subtypes. Elevated BNP levels have been correlated with atrial fibrillation, which is a common cause of cardioembolic strokes, underscoring its role in distinguishing this subtype from other stroke mechanisms. This dual connection between cardiac and cerebral health makes BNP a valuable tool for stratifying stroke etiology, particularly in patients where atrial fibrillation may be undiagnosed. However, BNP is not without limitations. Its levels can be influenced by non-neurological factors such as heart failure, renal dysfunction, and pulmonary hypertension, reducing its specificity for ischemic stroke. Additionally, the overlap in BNP levels among different stroke subtypes and other comorbid conditions may complicate its interpretation in clinical settings. Despite these challenges, BNP remains a promising biomarker when used in conjunction with other diagnostic tools, providing a more comprehensive approach to identifying cardioembolic strokes [20].

GFAP, an intrinsic component of the neural framework, rises to prominence following central nervous system damage, including ischemic strokes. Its presence in bodily fluids such as serum and cerebrospinal fluid sparks hope for its utility in early stroke diagnosis. GFAP has demonstrated high specificity (up to 85-95%) for distinguishing ischemic strokes from hemorrhagic strokes due to its release following astrocyte damage, which is more pronounced in hemorrhagic strokes. Its sensitivity, however, varies depending on the timing of sampling and the severity of the stroke, with reported values ranging from 60% to 80% in the early phases of ischemic events. The temporal dynamics of GFAP release make it particularly useful for early differentiation between stroke subtypes, which is critical for guiding appropriate therapeutic interventions. Despite its promise, GFAP has limitations. Its levels can be influenced by other central nervous system pathologies, such as traumatic brain injuries, infections, or neurodegenerative diseases, which may reduce its specificity in certain clinical scenarios. Additionally, the variability in GFAP levels across individuals and stroke severities highlights the need for standardized cut-off values to improve its diagnostic reliability. Furthermore, GFAP is less effective as a standalone biomarker for ischemic stroke detection and is best utilized in combination with other biomarkers or imaging modalities to enhance diagnostic accuracy [21,22].

Pre-hospital care: revolutionizing early stroke response

The pivotal role of rapid intervention in stroke management has led to transformative changes in pre-hospital care, particularly for acute ischemic stroke [23,24]. The advent of MSUs marks a significant leap forward in this domain. These units, equipped with state-of-the-art diagnostic tools, including CT scanners and telemedicine capabilities, represent more than just ambulances; they are mobile medical units capable of initiating stroke diagnosis and management in the field [25-27].

These units epitomize the principle of "time is brain" by offering rapid, on-site diagnosis and communication with specialized stroke centers. This approach significantly reduces the delay in treatment initiation, which is crucial for effective stroke management [28-30]. The impact of MSUs stretches beyond immediate care; they represent a paradigm shift in how stroke care is delivered, highlighting the importance of integrating advanced medical technology with swift, decentralized medical response.

Thrombolytic therapy, particularly alteplase, continues to be the linchpin of acute ischemic stroke treatment [31]. Recent research has delved deep into optimizing thrombolytic protocols, revealing a landscape rich in innovation and potential [32,33]. This research is not confined to tweaking existing protocols; it involves a comprehensive reassessment of how thrombolytic therapy is administered, including dosing, timing, and patient selection. The aim is to broaden the treatment window, thus including a wider range of patients who can benefit from this therapy, thereby mitigating the risk of long-term neurological deficits [32].

The exploration of novel thrombolytic agents is reshaping the future of stroke treatment. These new agents promise not just improvements in efficacy but also reductions in associated risks, offering hope for safer, more effective stroke interventions. Recent advancements in thrombolytic therapy have led to the development of novel agents that aim to improve efficacy while minimizing associated risks such as bleeding complications. Tenecteplase (TNK-tPA), a genetically modified variant of alteplase, has garnered significant attention due to its longer half-life, allowing for single-bolus administration, and its greater fibrin specificity, which reduces systemic bleeding risk. Clinical trials, including the Tenecteplase Versus Alteplase Before Endovascular Therapy for Ischemic Stroke (EXTEND-IA TNK) and the Norwegian Tenecteplase Stroke Trial (NOR-TEST), have shown promising outcomes, with tenecteplase demonstrating comparable or superior efficacy to alteplase in achieving reperfusion and improving clinical outcomes. Additionally, desmoteplase, derived from bat saliva, has been studied for its high fibrin specificity and low neurotoxicity, making it a potential candidate for extending the therapeutic window for thrombolysis. Although earlier trials like the Desmoteplase in Acute Ischemic Stroke (DIAS) and the Dose Escalation of Desmoteplase for Acute Ischemic Stroke (DEDAS) yielded mixed results, ongoing research is exploring optimal dosing and patient selection to maximize its utility. Emerging agents such as pamiteplase and other thrombolytics designed to target resistant clots or work synergistically with mechanical thrombectomy are also under investigation. These agents aim to broaden the applicability of thrombolysis to patients who were previously ineligible due to time constraints or contraindications [34,35].

Mechanical thrombectomy: the new frontier in stroke care

Mechanical thrombectomy has revolutionized the management of acute ischemic stroke, transforming it into a cornerstone of modern stroke care. Since its FDA approval in 2004, significant advancements have been made, particularly over the past decade, enhancing the precision, efficacy, and applicability of this procedure. The introduction and widespread adoption of stent retrievers, such as Solitaire (Medtronic, Dublin, Ireland) and Trevo (Stryker, Kalamazoo, MI, USA), marked a major breakthrough, offering higher recanalization rates, fewer complications, and faster clot retrieval compared to earlier devices like Merci (Inova, Falls Church, VA, USA). These innovations have significantly improved outcomes for patients with severe cerebral occlusions, opening new avenues of hope for those previously deemed ineligible for treatment [36-38].

Clinical trials conducted since 2013, including the Multicenter Randomized Clinical Trial of Endovascular Treatment of Acute Ischemic Stroke in the Netherlands (MR CLEAN), Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE), Endovascular Revascularization With Solitaire Device vs Best Medical Therapy in Anterior Circulation Stroke Within 8 h (REVASCAT), and Diffusion-Weighted Imaging or CTP Assessment With Clinical Mismatch (DAWN), have demonstrated the efficacy of thrombectomy in extending the treatment window to up to 24 hours for select patients with salvageable brain tissue. This has redefined patient selection criteria, allowing clinicians to leverage advanced imaging techniques, such as CTP and MRI-based penumbra assessments, to better identify candidates who may benefit from the procedure. The integration of AI into imaging analysis has further enhanced procedural planning, enabling faster and more accurate decision-making [36-38].

Technological advancements have also brought aspiration devices and combined techniques (stent retrievers with aspiration catheters) into clinical practice, improving clot retrieval efficiency. The use of balloon guide catheters has optimized flow control, reducing the risk of distal embolization and increasing the success rates of first-pass recanalization. Efforts to refine devices for smaller, distal vessel occlusions are expanding the applicability of thrombectomy to previously untreatable cases [37,38].

The implementation of the "drip-and-ship" model exemplifies the expanded reach of thrombectomy services. By facilitating rapid initial treatment at primary care centers and subsequent transfer to comprehensive stroke centers, this model has effectively bridged the gap between localized healthcare settings and advanced stroke interventions, ensuring timely and equitable access to care for a broader patient population [37,38].

These advancements collectively underscore the transformative progress in mechanical thrombectomy, making it a dynamic and evolving frontier in stroke care. With its ability to provide life-saving intervention and improve long-term outcomes, thrombectomy continues to redefine the landscape of acute ischemic stroke management.

Combination therapies: crafting a synergistic approach

Combination therapies in stroke treatment represent the convergence of thrombolytic and endovascular methods, offering synergistic benefits in acute ischemic stroke management. Approaches such as intravenous thrombolysis with alteplase or tenecteplase followed by mechanical thrombectomy have shown improved reperfusion rates and clinical outcomes, particularly for large vessel occlusions. Bridging therapy, where thrombolytics are administered prior to thrombectomy in a "drip-and-ship" model, ensures timely intervention. Intra-arterial thrombolysis combined with thrombectomy provides localized clot dissolution, reducing systemic bleeding risks. Emerging trends, including dual thrombolytic therapy and the use of neuroprotective agents, aim to optimize clot resolution and protect brain tissue during reperfusion. These advancements exemplify a comprehensive and tailored approach to stroke care [36-38].

The decision-making process in employing combination therapies is increasingly nuanced, informed by a robust evidence base and a deep understanding of individual patient profiles. This personalized approach moves away from a one-size-fits-all methodology, considering factors such as the patient's condition, the type of occlusion, and the timing of intervention.

In conclusion, the current trajectory of acute ischemic stroke treatment is marked by relentless innovation and a commitment to improving patient outcomes. The advancements in thrombolytic therapy and mechanical thrombectomy and the introduction of combination therapies signify a new era in stroke care. These developments are not just expanding the range of therapeutic options but are also reshaping the entire landscape of acute stroke management. As these therapies evolve, they continue to offer new hope and possibilities for patients afflicted.
