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. Limited demographic, safety, and outcome data were collected in a secure REDCap database. Detailed clinical data were not collected.
Results: Eleven children were reported to have received TNK between February 2023 and January 2024. Ten were adolescents (13-17 years old), and 1 was between 5 and 12 years old. TNK was given at an outside facility before transfer to the reporting facility in 7 cases. Final diagnosis was stroke in 8 cases and stroke mimic in 3 cases. No major safety concerns or TNK-related intracranial hemorrhages on follow-up imaging were reported.
Discussion: Our initial data suggest that TNK may be safe in childhood arterial ischemic stroke. Strategically designed prospective studies are needed to further define safety, optimal dosage, and efficacy of TNK in acute pediatric stroke.

Objective: To describe the characteristics of patients diagnosed with acute heart failure (AHF) in emergency departments (EDs) who develop cardiogenic shock (CS) not associated with ST-segment elevation acute coronary syndrome (STACS).
Methods: Information for patients diagnosed with AHF in 23 Spanish EDs and registered between 2009 and 2019 were included for analysis if the patients developed symptoms consistent with CS. We described baseline clinical characteristics related to cardiac decompensation and CS, as well as 30-day mortality.
Ischemia during exercise stress testing, an indication of coronary vasomotor dysfunction?

Background: Recently it has been suggested that coronary microvascular dysfunction (CMD) may explain the high false-positive rate of exercise electrocardiographic stress testing (EST). However, patients with angina but non-obstructive coronary artery disease (ANOCA) present with a broader spectrum of coronary vasomotor dysfunction (CVDys), namely coronary artery spasm (CAS), CMD or a combination of both. We aim to investigate the diagnostic value of EST for the entire CVDys spectrum.

Background: A minimum threshold activated clotting time (ACT) to guide heparin dosing during percutaneous coronary intervention (PCI) is associated with lower ischemic complications. However, data are variable regarding the risk of high ACT levels. The aim of this study was to assess the impact of peak procedural ACT on complications and mortality for transfemoral and transradial access PCI.

Introduction: Ischaemic heart disease (IHD) and cerebrovascular disease are leading causes of morbidity and mortality worldwide. Cerebral small vessel disease (CSVD) is a leading cause of dementia and stroke. While coronary small vessel disease (coronary microvascular dysfunction) causes microvascular angina and is associated with increased morbidity and mortality.

The brain is composed of a dense and ramified vascular network of arteries, veins and capillaries of various sizes. One way to assess the risk of cerebrovascular pathologies is to use computational models to predict the physiological effects of reduced blood supply and correlate these responses with observations of brain damage. Therefore, it is crucial to establish a detailed 3D organization of the brain vasculature, which could be used to develop more accurate in silico models.
