Stroke: 5 New Findings
Here: 5 new things to know about stroke -- its link with perioperative A-fib; the danger of cocaine; rehab possibilities with an Alzheimer drug; reducing stroke risk with potassium; and a potential screen for occult A-fib after cryptogenic stroke.
In the 5 slides that follow, you’ll summaries of key findings from 5 recent articles about stroke. Among the highlights:1 Perioperative A-fib” confers a long-term increase in ischemic stroke risk.2. Cocaine can spell cardio/cerebrovascular danger--regardless of route of ingestion.3. An Alzheimer drug appears to have promise for stroke victims.4. In older women, potassium can reduce stroke risk.5. Monitoring of the radial artery pulse may be a useful means of screening for occult A-fib in patients with cryptogenic stroke.Â
The following 5 slides highlight key findings from 5 recent articles about stroke. These include: 1. Perioperative A-fib” confers higher long-term risk of ischemic stroke. 2. Cocaine use can spell cardio/cerebrovascular danger-- regardless of route of ingestion. 3. An Alzheimer drug appears to have promise for stroke victims. 4. In older women, potassium can reduce stroke risk. 5. Radial artery pulse monitoring may help screen for occult A-fib after cryptogenic stroke.
A large study has established that perioperative AF associated with non-cardiac surgery is a risk factor for ischemic stroke. Whether to anticoagulate in the presence of AF remains to be studied. Click Here
Regardless of the route by which cocaine is administered, toxic amounts can be absorbed leading to acute cardiovascular or cerebrovascular emergencies, and seizures. Click Here
The Alzheimer drug, memantine, which blocks the neurotransmitter glutamate--specifically at the NMDA receptor-- could aid in recovery from stroke. Motor behavior improved in memantine-treated animals, and sensory mapping seemed to reestablish in the cerebral cortex. Click Here
This study found an inverse association between dietary potassium intake and the incidence of ischemic stroke as well as all-cause mortality in older women. Click Here
Kallmunzer and colleagues found convincing preliminary evidence that measurement of the peripheral pulse (MPP) at the radial artery can detect occult AF after a cryptogenic stroke. Click Here
