Ischemic stroke incidence following COVID-19 bivalent booster vaccination in adults 65 years and older

A retrospective cohort study examined ischemic stroke and transient ischemic attack cases within 21 days of COVID-19 bivalent Pfizer vaccination in Kaiser Permanente patients aged 65+, finding an incidence of 34.3 per 100,000. While a safety signal was detected requiring further investigation, the authors appropriately note that validation of any causal association between vaccination and stroke risk is needed before conclusions can be drawn.

Preventability of Ischemic Stroke and Transient Ischemic Attack in a Tertiary Care Center in Argentina

This retrospective study evaluated patients with acute ischemic stroke or transient ischemic attack to assess how many cases could have been prevented through better management of vascular risk factors such as hypertension, dyslipidemia, atrial fibrillation, and smoking. The researchers developed a 10-point preventability scale to classify the degree to which each event was avoidable based on the optimization of modifiable risk factors at presentation.

Statins' Effect on Quality of Life and Functioning in Older Stroke Patients: Systematic Review and Meta-Analysis

This systematic review evaluated 6 randomized controlled trials and 16 cohort studies (66,273 patients, mean age 65-79) examining statin use for secondary prevention after ischemic stroke or transient ischemic attack. Meta-analysis of cohort studies showed a positive association between statins and improved functioning, though individual trials had mixed results regarding quality of life, with significant methodological limitations noted across included studies.

Left Atrial Reservoir Strain as a Predictor of Cardioembolic Ischemic Stroke and Atrial Fibrillation

This retrospective study evaluated left atrial reservoir strain using echocardiography in 79 stroke/TIA patients without prior atrial fibrillation history to identify cardiac sources of emboli. Reduced reservoir strain was associated with cardioembolic stroke mechanisms and atrial fibrillation occurrence, suggesting it may aid in stroke risk stratification and AF detection.

Cerebrovascular Events and Associated Risk Factors in Cervical Fibromuscular Dysplasia: A Systematic Review and Meta-Analysis

This systematic review and meta-analysis examines the incidence and risk factors for cerebrovascular events (including stroke) in patients with cervical fibromuscular dysplasia, a non-atherosclerotic vascular condition affecting arterial walls. The study synthesizes evidence to characterize stroke risk and associated factors in this patient population.
