This study looks at how quickly stroke patients receive treatment after arriving at Gonesse Hospital and whether this affects their recovery. Researchers will measure the time between a patient's arrival and the start of clot-busting treatment (called Door-to-Needle Time), as well as the time from symptom onset to hospital arrival (Home-Time). The goal is to see if treatment delays impact recovery, and to find ways to improve stroke care in the hospital.

Inclusion Criteria:

• Patients aged 18 years or older
• Confirmed diagnosis of acute ischemic stroke on imaging
• Initial acute stroke care provided at Gonesse Hospital during the study period (3 months)
• Intravenous thrombolysis (r-tPA) initiated at the hospital
• Availability of clinical and timing data to calculate Door-to-Needle Time (DNT)

Exclusion Criteria:

• Patients with hemorrhagic stroke or subarachnoid hemorrhage (SAH)
• Thrombolysis initiated before hospital arrival
• Missing, incomplete, or unusable timing data for DNT calculation

The study population will consist of adult patients (aged 18 and over) admitted to the Gonesse Hospital for acute ischemic stroke. All participants must have received intravenous thrombolysis (r-tPA) initiated at the hospital during the 3-month study period. Only patients with complete clinical and time-tracking data enabling the calculation of Door-to-Needle Time will be included.
