NCT ID: NCT05044208 Recruiting - Atrial Fibrillation Clinical Trials

Echocardiographic Predictors of Atrial Fibrillation

EPAF-7
Start date: January 1, 2021
Phase:
Study type: Observational

This prospective study aims to identify the diagnostic accuracy of echocardiographic predictors of atrial fibrillation in patients with ESUS (embolic stroke of undetermined source) or TIA (transient ischemic attack).

NCT ID: NCT03158259 Recruiting - Hemorrhagic Stroke Clinical Trials

Prehospital Advanced Diagnostics and Treatment of Acute Stroke

Treat-NASPP
Start date: May 15, 2017
Phase: N/A
Study type: Interventional

The objective of this study is to investigate the effectiveness of prehospital diagnosis and, when appropriate, of intravenous thrombolytic treatment of ischemic stroke. At the same time, we will take the opportunity to do an explorative study with the aim to further improve the intervention by biomarkers, and outcome measures volumetric measured by MRI images. The intervention study aim to: - Determine the time from symptom onset to thrombolytic treatment in the Mobila Stroke Unit (MSU) compared to the conventional model - Determine the number of patients receiving thrombolytic treatment within the 4.5 hrs window in the MSU compared to the conventional model - Determine if thrombolytic treatment in the MSU, when adjusted for time, results in better mRS- and Barthel outcome compared to treatment in the conventional model The explorative study aim to - Determine if final IS infarction volume estimated by MRI, is independently correlated with time from symptom onset to thrombolytic treatment - Define cut-off values for GFAP and RBP4 combined that with sufficient specificity and sensitivity can distinguish ICH from IS - Determine the influence of time to treatment on pro-inflammatory markers after stroke Hypothesis Intervention study I. The Treat - NASPP MSU model is feasible and reduces onset to treatment time less than 15 min II. The number of patient treated with thrombolysis within 4.5 hrs of symptom onset is significantly increased in the Treat-NASPP MSU model III. Treatment in the Treat-NASPP MSU model does not result in increased day 90 mRS and Barthel as compared to the conventional model when adjusted for time IV. Prehospital thrombolytic treatment of stroke does not increase the risk of secondary cerebral bleeding as compared to in-hospital thrombolytic treatment of stroke (cerebral bleeding worsening within 36 hrs less than 4 per cent, Norsk hjerneslagregister) Explorative study V. The final infarct volume, estimated by MRI, is significantly reduced when thrombolytic treatment is initiated already in the MSU VI. Biomarkers is a valid tool in the hyper acute phase of cerebral illness to exclude contraindication to thrombolysis VII. Reduced onset to treatment time results in lower levels of selected pro-inflammatory molecules
