AI Article Synopsis
- The study analyzed the relationship between the use of nonsteroidal anti-inflammatory drugs (NSAIDs) and stroke risk in a large population over more than nine years.
- Current users of nonselective and COX-2-selective NSAIDs were found to have a significantly higher risk of stroke compared to non-users, while COX-1-selective NSAIDs showed no increased risk.
- Specific NSAIDs like naproxen and rofecoxib were linked to a notably greater risk of stroke, highlighting the need for caution in prescribing these medications.
Article Abstract
Background: In clinical trials, cyclooxygenase (COX)-2-selective nonsteroidal anti-inflammatory drugs (NSAIDs) were associated with an increased risk of thromboembolic events. We studied the association between NSAID use and risk of stroke in the prospective, population-based Rotterdam Study.
Methods: We followed 7636 persons free of stroke at baseline (1991-1993) for incident stroke until September 2004. Data on all filled prescriptions came from pharmacy records. With Cox regression models, we calculated crude and adjusted hazard ratios (HRs) of stroke for time-dependent current use, compared with never use, of NSAIDs grouped according to COX selectivity (COX-1 selective, nonselective, and COX-2 selective) and individual NSAIDs.
Results: At baseline, the mean age of the study sample was 70.2 years, and 61.3% were female. During 70 063 person-years of follow-up (mean, 9.2 years), 807 persons developed a stroke (460 ischemic, 74 hemorrhagic, and 273 unspecified). Current users of nonselective (HR, 1.72; 95% confidence interval [CI], 1.22-2.44) and COX-2-selective (HR, 2.75; 95% CI, 1.28-5.95) NSAIDs had a greater risk of stroke, but not users of COX-1-selective NSAIDs (HR, 1.10; 95% CI, 0.41-2.97). Hazard ratios (95% CIs) for ischemic stroke were 1.68 (1.05-2.69) for nonselective and 4.54 (2.06-9.98) for COX-2-selective NSAIDs. For individual NSAIDs, current use of the nonselective naproxen (HR, 2.63; 95% CI, 1.47-4.72) and the COX-2-selective rofecoxib (HR, 3.38; 95% CI, 1.48-7.74) was associated with a greater risk of stroke. Hazard ratios (95% CIs) for diclofenac (1.60 [1.00-2.57]), ibuprofen (1.47 [0.73-3.00]), and celecoxib (3.79 [0.52-27.6]) were greater than 1.00 but were not statistically significant.
Conclusions: In the general population, we found a greater risk of stroke with current use of nonselective and COX-2-selective NSAIDs. The risk of stroke was not limited to the use of COX-2-selective NSAIDs.

Tenecteplase for the Treatment of Pediatric Arterial Ischemic Stroke: A Safety Surveillance Report.
Neurology
February 2025
Department of Neurology, Washington University School of Medicine, St. Louis, MO.
Objectives: Intravenous tenecteplase (TNK) is increasingly used to treat adult patients with acute arterial ischemic stroke, but the risk profile of TNK in childhood stroke is unknown. This study aims to prospectively gather safety data regarding TNK administration in children.
Methods: Since December 2023, a monthly email survey was sent to participants recruited from the International Pediatric Stroke Study and Pediatric Neurocritical Care Research Group querying recent experience with TNK in childhood stroke.
Arterial Input Function Dispersal on Acute Brain CT Perfusion Scan in Patients With Acute Stroke and an Intracardiac Thrombus.
Neurology
February 2025
Department of Neurology, John Hunter Hospital, Newcastle, Australia.
Article Synopsis
- Hyperacute cardiac CT is more effective than transthoracic echocardiography in detecting intracardiac thrombus, but its routine use is limited due to costs and risks.
- A study of 1,136 ischemic stroke or TIA patients found that longer arterial input function (AIF) dispersal times correlate with the presence of thrombus and worse outcomes, with a specific cutoff of 33 seconds indicating higher risk.
- The findings support using AIF dispersal measurements to help identify patients who may benefit from cardiac imaging, potentially optimizing resource use in stroke management.
Intra-Arterial Tenecteplase Following Endovascular Reperfusion for Large Vessel Occlusion Acute Ischemic Stroke: The POST-TNK Randomized Clinical Trial.
JAMA

Department of Neurology, Xinqiao Hospital and The Second Affiliated Hospital, Army Medical University (Third Military Medical University), Chongqing, China.
Importance: The impact of adjunctive intra-arterial tenecteplase administration following near-complete to complete reperfusion by endovascular thrombectomy (EVT) for acute ischemic stroke is unknown.
Objective: To assess the efficacy and adverse events of adjunctive intra-arterial tenecteplase in patients with large vessel occlusion stroke who had achieved near-complete to complete reperfusion (defined as a score on the expanded Thrombolysis in Cerebral Infarction [eTICI] scale of 2c to 3) after EVT.
Design, Setting, And Participants: Investigator-initiated, randomized, open-label, blinded outcome assessment trial implemented at 34 hospitals in China among 540 patients with stroke due to proximal intracranial large vessel occlusion within 24 hours of the time they were last known to be well, with an eTICI score of 2c to 3 after EVT, and without prior intravenous thrombolysis.

JAMA

Department of Neurology, Xinqiao Hospital and The Second Affiliated Hospital, Army Medical University (Third Military Medical University), Chongqing, China.
Importance: Persisting or new thrombi in the distal arteries and the microcirculation have been reported to limit the benefits of successful endovascular thrombectomy for patients with acute ischemic stroke. It remains uncertain whether intra-arterial thrombolysis by urokinase following near-complete to complete reperfusion by thrombectomy improves outcomes among patients with ischemic stroke due to large vessel occlusion.
Objective: To assess the efficacy and adverse events of intra-arterial urokinase after near-complete to complete reperfusion by thrombectomy for acute ischemic stroke due to large vessel occlusion.

Clonal haematopoiesis of indeterminate potential (CHIP) is associated with macrovascular diseases, including coronary artery disease and stroke. However, the effects of CHIP on microvascular complication have not been evaluated in individuals with type 2 diabetes (T2D). This study included 20,712 T2D participants without prevalent diabetic microvascular complication (DMCs) and hematologic malignancy at baseline.
