Market Dynamics

The transient ischemic attack market is experiencing steady growth, driven by the increasing awareness of transient ischemic attack as a warning sign of stroke and the subsequent push for early diagnosis and preventive treatment. Advances in neuroimaging and diagnostic technologies are enabling faster and more accurate identification of transient ischemic attack, leading to timely interventions and improved patient outcomes. Growing investments in public health initiatives and stroke prevention programs are also contributing to the market expansion.

Pharmacological advancements, particularly in anti-platelet agents, anticoagulants, and statins, are enhancing therapeutic outcomes and reducing the risk of recurrent attacks. The preference for oral administration and non-invasive pharmacological treatments supports the market growth, particularly in outpatient care settings.

In July 2024, the American Heart Association awarded a consortium grant to pool and share neuroimaging data from its Get with the Guidelines–Stroke registry (9.6 million cases). This effort aims to train AI tools that support the faster and more accurate identification of transient ischemic attack risk and outcomes.

Additionally, the rise in aging populations globally, coupled with increasing prevalence of risk factors such as hypertension, diabetes, and atrial fibrillation, is fueling demand for transient ischemic attack therapies. Emerging markets in Asia Pacific and Latin America are witnessing improved healthcare infrastructure and rising patient access, further accelerating market penetration.

Market Trends

• Shift Toward Outpatient & Rapid‑Access Transient Ischemic Attack Clinics

Healthcare systems are increasingly adopting outpatient care models and rapid-access clinics for managing low-risk transient ischemic attack patients, aiming to improve care efficiency and reduce hospital admissions. These clinics provide same-day neuroimaging, vascular assessments, and neurology consultations, allowing for timely diagnosis and initiation of preventive therapies.

In December 2023, at Massachusetts General Hospital, the RAVEN (Rapid Access Vascular Evaluation–Neurology) protocol enabled low-risk transient ischemic attack and minor stroke patients to avoid hospital admission by shifting to a rapid-access stroke clinic. Between April and September 2020, this approach reduced emergency department stays by 44% (13.7 hours vs. 24.4 hours), minimized duplicative imaging, and ensured that 89% of patients were seen within five business days. Clinical outcomes remained comparable to inpatient care, with a 90-day recurrence rate of just 1% versus 2%.

• Rise in Point-of-Care & Portable Diagnostic Technologies

The transient ischemic attack market is witnessing the growing adoption of point-of-care and portable diagnostic tools aimed at improving early detection and access to care, especially in remote or underserved areas. These innovations are streamlining diagnostics and reducing delays in clinical decision-making.

In July 2024, Bracco Imaging partnered with BURL Concepts to integrate Bracco’s microbubble contrast agent with BURL’s SONAS portable, battery-powered ultrasound system, aimed at assessing cerebral perfusion non-invasively. This CE-marked device has been tested in clinical settings—including transient ischemic attack and stroke patients—and is under FDA trial submission, with early studies showing its potential to facilitate diagnostic evaluations outside traditional imaging suites, particularly in pre-hospital or bedside scenarios.

Market Opportunities

• Expansion of AI-Powered Imaging Platforms for Early Transient Ischemic Attack Detection

The growing integration of artificial intelligence (AI) in neuroimaging presents a major opportunity for enhancing the early diagnosis of transient ischemic attacks. AI algorithms are increasingly being used to detect subtle cerebral ischemic changes that may be missed by traditional imaging. In April 2025, a deep learning-based multi-channel MRI model demonstrated diagnostic accuracies above 99% for both cerebral infarction and transient ischemic attack, significantly outperforming manual readings.

This trend creates opportunities for radiology vendors and health systems to deploy AI-enabled triage tools in emergency and outpatient settings, improving time-to-treatment and reducing recurrence risks. The demand is robust in stroke centers and teleneurology networks, where fast and precise diagnosis is critical. Startups and imaging companies developing explainable, real-time AI solutions are well-positioned to capture this unmet need for diagnostic precision in transient ischemic attack care pathways.

• Growing Adoption of Dual Antiplatelet Therapy (DAPT) in High-Risk Transient Ischemic Attack Patients

Emerging clinical evidence supporting the use of dual antiplatelet therapy (DAPT) is opening new opportunities in the pharmacological management of transient ischemic attack. In October 2024, the INSPIRES trial demonstrated that initiating DAPT (aspirin plus clopidogrel) within 72 hours of a high-risk transient ischemic attack significantly reduced recurrent events without increasing the risk of major bleeding over 21 days.

This clinical shift is prompting pharmaceutical companies to optimize fixed-dose DAPT combinations, improve compliance-focused oral regimens, and explore newer agents like ticagrelor in transient ischemic attack prevention. With guideline bodies increasingly recommending short-term DAPT in acute transient ischemic attack management, drug manufacturers and generics developers have an opportunity to expand their cardiovascular portfolios with targeted secondary prevention therapies for high-risk patients.
