Stroke

Cardiovascular departments are playing a role in stroke interventions at numerous health systems, working as part of the stroke care team with neurologists, radiology and the emergency department. Stroke first has be be classified as ischemic or hemorrhagic. These have very different care pathways. Ischemic strokes are increasingly being treated with neurological-interventional therapy that includes catheter based mechanical thrombectomy to remove the clot. This is a more aggressive treatment compared to traditional IV administration of tissue plasminogen activator (tPA) thrombolytic therapy to dissolve the clot. Subarachnoid hemorrhage (SAH) and intracerebral hemorrhage (ICH) brain bleeds can also be treated in some cases stent flow diverters and embolization coils.

Effective, but not worth the cost: CEPD use during TAVR fails to make a significant difference
Cerebral embolic protection devices are proven to work. However, according to one cardiologist, they are still not consistently reducing stroke rates.
How the shape, size and location of calcified carotid plaques affect stroke risk
A new analysis provides further insight into factors affecting plaque stability and subsequent ischemic events
A closer look at world’s first TAVR patient treated with new cerebral embolic protection device
The device covers three vessels at once and can be deployed through the patient's TAVR access site. Researchers shared their first-in-human experience in JACC: Case Reports.
Cannabis is bad for the heart—should the risk be taken more seriously?
Use of the drug more than doubles a person's risk of dying from heart disease, according to a new analysis of 24 different studies. In a separate editorial, two physicians shared their concerns and highlighted the importance of discussing these risks with patients.
Extended CTA exams more than triple stroke detection
New research reveals that expanding CT angiography scans of the head and neck to capture the area at least 6 cm below the carina can significantly increase the detection of cardioaortic thrombi.

Black stroke patients hospitalized longer than white patients

Even after adjusting for factors such as income, comorbidities and stroke severity indicators, a prolonged length of stay was more common for Black patients.

An example of artificial intelligence (AI) automated detection of a intracranial hemorrhage (ICH) in. a CT scan used to send alerts to the stroke acute care team before a radiologist even sees the exam. Example shown by TeraRecon at RSNA 2022.

VIDEO: Radiology AI aids acute care and other departments

Sanjay Parekh, PhD, senior market analyst with Signify Research, explains how some radiology AI is being adopted outside of radiology departments to improve care.

Neuroimaging recedes behind other cost compilers in stroke care

Contrary to older research that showed neuroimaging emerging as the single most dominating cost contributor in ischemic stroke care for older Americans, a new study shows treatment and other line items account for bigger slices of the bill.

VIDEO: Role of PFO closure in stroke prevention

John Carroll, MD, director of interventional cardiology and professor of medicine at the University of Colorado, explains the state of transcatheter closure of patent foramen ovale (PFO) to prevent stroke.

Researchers awarded $37M to see if Apple Watch can lower stroke risk among AFib patients

Could wearables help AFib patients take fewer blood-thinning medications and reduce their risk of stroke? The team behind a new seven-year analysis hopes to find out.

Sentinel Boston Scientific PROTECTED TAVR stroke disabling stroke

TAVR embolic protection devices fail to reduce stroke risk, but some cardiologists—and a leading vendor—remain encouraged

The PROTECTED TAVR results presented at TCT 2022 resulted in a mix of reactions. For some cardiologists, the slight reduction in the risk of a disabling stroke after TAVR is a positive result. For others, it was simply not enough.

VIDEO: AI for stroke detection on CT imaging

Bibb Allen, MD, FACR, chief medical officer of the American College of Radiology (ACR) Data Science Institute, explains the trend of using AI for the automated detection of stroke on computed tomography (CT) imaging and the need to include radiologists on the stroke care team.
