Summary

Along with the current clinical trial, the efficacy and safety of 180 mg loading dose of ticagrelor administered within the first 24 hours of first-ever ischemic stroke compared to 300 mg clopidogrel were assessed through NIHSS, mRS, duration of hospital stay, and possible adverse effects.

Detailed description

The investigators will conduct a single-blinded randomized controlled trial between October 2022 and December 2023 after approval of the ethical committee of the faculty of medicine at Kafr el-Sheik University. The investigators got written informed consent from all eligible patients or their first order of kin before randomization. The study will be composed of 2 arms ticagrelor arm, which consisted of 450 patients who received a 180 mg loading dose followed by 90 mg b.i.d from the 2nd to the 90th day), and the Clopidogrel arm consisting of 450 patients who received (a 300 mg loading dose during the first 24 hours of stroke onset followed by 75 mg once daily from the 2nd day to the 90th day) Study Procedures: Every patient in our study will undergo: * clinical workup: History, clinical assessment \& NIHSS were recorded on admission, day 7, and the Modified Rankin Scale as a follow-up after one week and 3 months. * Detection of Risk Factors \& Profiles: 1. Echocardiography\& TOE: in indicated patients 2. ECG Monitoring: daily ECG monitoring will be performed in indicated patients. 3- Carotid Duplex: carotid duplex in indicated patients. 4- ESR \& Lipid Profile\& liver functions: All will be tested routinely for all patients. * Imaging Follow UP 1. Non-contrast CT brain on admission 2. Day 2 MRI: after 2 days of admission, all the patients in this study will have a brain MRI (stroke protocol; T1W, T2W, FLAIR, DWI, T2 Echo Gradient, MRA of all intra-cerebral vessels). 3. CT brain: Any patient with unexplained clinical deterioration at any time throughout his/her hospital stay will be urgently imaged by CT. * Primary End Point: The primary efficacy outcome was the rate of new ischemic stroke at 90 days, and the primary safety outcome was the rate of drug hemorrhagic complications using the PLATO bleeding definition. • Secondary End Point: the secondary efficacy outcomes were to evaluate the rates of patients who achieved a significant reduction in NIHSS (decrease of four points or more) (21) at the seventh day or discharge compared to baseline, the rates of a favourable outcome with (mRS = 0-2) (19,20) after one week and after 90 days in a face-to-face interview in the outpatient clinic, rates of composite of recurrent stroke, myocardial infarction and death due to vascular events after 90 days of follow-up, while the secondary safety outcome was the rate of treatment-related adverse effects assessed by a follow-up questionnaire.
