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.

Positron emission tomography (PET) nuclear imaging has seen rapid expansion in cardiology and oncology due to its improve accuracy over SPECT and its ability to expand into new areas of cardiovascular imaging. A new review in the American Heart Association journal Stroke outlines another possible use of PET to assess carotid artery atherosclerosis for stroke prevention.

PET holds promise for carotid plaque assessments

PET has already gained significant momentum in recent years. Now, researchers are pointing to another possible use for the popular imaging modality: assessing carotid artery atherosclerosis.

Contego Medical, a North Carolina-based medical device company, has received U.S. Food and Drug Administration (FDA) approval for its new all-in-one carotid stenting offering, the Neuroguard IEP System

Medtronic launches full distribution of new 3-in-1 carotid stent

The device, manufactured by Contego Medical, was designed with rising procedure volumes and stroke risks in mind.

Plant-based diets linked to lower dementia risk for vulnerable heart patients

Adults with a history of CVD, type 2 diabetes and stroke were all associated with a lower dementia risk if they ate a whole food, plant-based diet. The study, published in JACC: Advances, was based on data from more than 71,000 U.K. Biobank participants.

Plant-based diets linked to lower risks of death, heart disease, stroke and diabetes

Diets that prioritize plant-based foods are associated with several health benefits, according to a new study of more than 3.4 million adults. Such diets also show potential to reduce greenhouse gas emissions.

Stroke risk after TAVR still much higher for female patients

Women are associated with a significantly higher rate of in-hospital disabling strokes than men, according to a new study of nearly 380,000 TAVR patients. What can cardiologists do to help limit these complications?
