Association of direct oral anticoagulation management strategies with clinical outcomes for adults with atrial fibrillation.
This study investigated the impact of an anticoagulation management service (AMS) on clinical outcomes of adults with atrial fibrillation (AF). This retrospective cohort study was conducted in 3 Kaiser Permanente regions, with each region taking a slightly different approach to direct oral anticoagulant (DOAC) care. These approaches included (1) usual care (UC) by the prescribing clinician, (2) UC plus an automated population management tool (PMT), or (3) pharmacist-managed AMS care. The study included 44,746 adults with a diagnosis of AF who initiated DOAC or warfarin between August 2016 and January 1, 2020, 6182 in the UC model, 33,624 in the UC plus PMT care model, and 4939 in the AMS care model. Baseline characteristics (mean age, 73.1 years, 56.1% male, 67.2% non-Hispanic White, median CHA2DS2-VASc [congestive heart failure, hypertension, age ≥75 years, diabetes, stroke, vascular disease, age 65-74 years, female sex] score of 3 [IQR, 2-5]) were well balanced after inverse probability of treatment weighting (IPTW). The cohort was followed over a median of 2 years, and patients who received the UC plus PMT or AMS care model did not have significantly better outcomes than those who received only UC.

Distal embolic protection use during transfemoral carotid artery stenting is associated with improved in-hospital outcomes.
Researchers sought to assess in-hospital outcomes in patients who had undergone transfemoral carotid artery stenting (tfCAS) with and without embolic protection using a distal filter. Patients undergoing tfCAS were identified in the Vascular Quality Initiative and those who received proximal embolic balloon protection were excluded. Outcomes of interest were stroke, death, composite stroke/death, myocardial infarction, transient ischemic attack, and hyperperfusion syndrome. Results indicated that tfCAS performed without attempted distal embolic protection was associated with higher risk of in-hospital stroke and death; tfCAS after a failed attempt at filter placement had equivalent stroke/death to patients with no filter attempted, but higher risk of stroke/death compared with those with successfully placed filters. The researchers concluded that these findings support current Society for Vascular Surgery guidelines and, if a filter cannot be safely placed, alternative approaches to carotid revascularization should be considered.

Statin therapy is associated with improved perioperative outcomes and long-term mortality following carotid revascularization in the Vascular Quality Initiative.
This study evaluated the outcomes of carotid artery stenosis (CAS) patients using statin therapy before undergoing carotid revascularization in the Vascular Quality Initiative registry. The authors identified all patients who underwent carotid endarterectomy (CEA), transfemoral carotid artery stenting (tfCAS), or transcarotid artery revascularization (TCAR) in the Vascular Quality Initiative registry from January 2016 to September 2021. Compared with statin use, no statin use was associated with a higher risk of in-hospital stroke or death and 5-year mortality among CEA and tfCAS patients, although there was no significant difference in outcomes among TCAR patients.
