Acute ischemic stroke (AIS) - Epidemiology Forecast - 2032

Key Highlights

• The incidence of ischemic stroke has been increasing in younger adults, largely driven by a rise in diabetes, obesity, and metabolic syndrome in this age group. A sedentary lifestyle is one of the major risk factors for an ischemic stroke.
• Misdiagnosis and delayed diagnosis continue to be challenging for ischemic stroke patients and might lead to a rise in mortality rate.
• The 7MM accounted for over 1.5 million cases of acute ischemic stroke in 2022. The US reported the highest number of cases of acute ischemic stroke, with more than 700,000 in 2022, owing to the long-term psychological, physical, and social consequences.
• The risk of acute ischemic stroke is similar in men and women in the US. However, in EU4 and the UK, and Japan, it has been found that men are at a higher risk than women.
• Assessments showed that the US accounted for less than 600,000 acute ischemic stroke cases in both males and females in 2022. While in Japan, males were affected more, accounting for nearly 100,000 cases compared to females (around 90,000 cases).

DelveInsight's'Acute Ischemic Stroke (AIS) - Epidemiology Forecast - 2032' report delivers an in-depth understanding of the historical and forecasted epidemiology of acute ischemic stroke (AIS) in the United States, EU4 (Germany, France, Italy, and Spain) and the UK, and Japan.

Acute Ischemic Stroke (AIS) Overview

Acute ischemic stroke (AIS) occurs due to the blockage in the artery resulting in reduced blood flow to the brain that damages and interrupts the brain functions. Every year around 5.5 million people die from stroke, making it the world's second leading cause of death. Moreover, a high burden of morbidity is also seen in stroke patients leaving nearly 50% of stroke survivors disabled. Of total stroke cases, approximately 70-85% of cases are attributed to ischemic stroke. Common signs and symptoms in patients with acute stroke include hemiparesis, sensory deficits, diplopia, dysarthria, and facial droop. Additionally, the symptoms commonly attributed to increased intracranial pressure, such as nausea, vomiting, headache, and blurred or double vision, may also provide evidence supporting a stroke. Based on the etiology, AIS is divided into four subtypes: 20% cardioembolic, 20% atherosclerosis (large artery disease), 25% lacunar (small vessel disease), and 5% other causes.

Acute Ischemic Stroke (AIS) Diagnosis

For the diagnosis of acute ischemic stroke (AIS), detection is emphasized by the term "time is brain" as the delay in diagnosis can impact the treatment choice. The diagnosis is based on clinical features and data collected by tests such as brain imaging (computed tomography/MRI), cardiac imaging (echocardiography, among others), duplex imaging of extracranial arteries, arteriography, and laboratory assessments for a prothrombotic state. Additionally, the National Institutes of Health Stroke Scale (NIHSS) is widely used to assess the neurological severity of acute ischemic stroke. However, early stroke detection is still critical in rural areas and small clinics due to the unavailability of costly diagnostic tools. Also, the delay in diagnosis can worsen stroke and hamper treatment.

Further, atypical presenting symptoms associated with brain stem and cerebellar-posterior circulation can cause over, under, and misdiagnosis of stroke. Additionally, misdiagnosis can be a risk in young patients with ischemic stroke, leading to delayed recognition, preventing thrombolytic therapy, and increasing morbidity and mortality. Hence, misdiagnosis limits the opportunities for a better treatment outcome.

Nevertheless, the advances in diagnostic tools and equipment, continuous efforts in discovering blood-based biomarkers, and improving diagnosis would drive the growth of the acute ischemic stroke market. Heart and stroke screenings in developed countries will also contribute to market growth.

Acute Ischemic Stroke (AIS) Epidemiology

As the market is derived using a patient-based model, the acute ischemic stroke (AIS) epidemiology chapter in the report provides historical as well as forecasted epidemiology segmented by total diagnosed incidence cases of acute ischemic stroke, gender-specific cases of acute ischemic stroke, age-specific cases of acute ischemic stroke, type-specific cases of acute ischemic stroke in the 7MM covering the United States, EU4 countries (Germany, France, Italy, and Spain), United Kingdom, and Japan from 2019 to 2032.

• Among the 7MM, the US accounted for the highest number of cases of acute ischemic stroke, with more than 700,000 cases, in 2022, owing to the long-term psychological, physical, and social consequences among the population.
• Among the EU4 and the UK, Germany accounted for the highest number of acute ischemic stroke cases (around 250,000). On the contrary, Spain accounted for the least cases in 2022.
• Assessments showed that the US accounted for less than 600,000 acute ischemic stroke cases in both males and females in 2022. While in Japan, more males were affected by acute ischemic stroke accounting for nearly 100,000 cases, and females for around 90,000 cases in 2022.
• In Japan, there were around 60,000 cases of large artery, 58,000 cases of small artery occlusions, 77,000 cases of cardioembolism, and 35,000 cases of other/undetermined types in 2022.
