Details and patient eligibility

About

Along with the current clinical trial, the efficacy and safety of 180 mg loading dose of ticagrelor administered within 24 hours of first-ever large-vessel ischemic stroke compared to 200 mg cilostazol were assessed through NIHSS, mRS, and possible adverse effects.

Full description

The investigators conducted a single-blinded randomized controlled trial between December 2022 and February 2024 after approval of the ethics 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 290 patients who received a 180 mg loading dose followed by 90 mg b.i.d from the 2nd to the 90th day), and the cilostazol arm consisting of 290 patients who received (a 200 mg loading dose during the first 24 hours of stroke onset followed by 100 mg twice 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: Echocardiography TTE : in indicated patients 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 Non-contrast CT brain on admission 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). 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) at the seventh day or discharge compared to baseline, the rates of a favorable outcome with (mRS = 0-2) after one week and after 90 days in a face-to-face interview in the outpatient clinic, rates of a 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

Inclusion criteria

  • the investigators included both genders with eligible ages ranging between 18-75 years, with the first-ever presentation with acute large-vessel ischemic stroke who received antiplatelet treatment within the first 24 hours of the onset of ischemic stroke. Patients with previous transient ischemic attacks (TIA) were not excluded from the study. Patients are not eligible for rt-PA treatment

Exclusion criteria

  • he investigators excluded patients who had not been followed up on for 90 days after enrollment, those with NIHSS ≤ 3 or ≥ 25 or who had rapidly resolving symptoms before imaging results, and patients with a known history of persistent or recurrent CNS pathology (e.g., epilepsy, meningioma, multiple sclerosis, history of head trauma with a residual neurological deficit).

the investigators excluded patients who had clinical seizures at the onset of their stroke, as well as those who had symptoms of any major organ failure, active malignancies, or an acute myocardial infarction within the previous six weeks, and those who were on warfarin, regular ticagrelor during the week before admission, or chemotherapy within the previous year.

The investigators excluded patients with active peptic ulcers, GIT surgery, bleeding history within the last year, and those with a history of major surgery within the last three months.

The investigators ruled out of our trial patients who had a known allergy to the study drugs and those with INR > 1.4 or P.T. >18 or blood glucose level < 50 or > 400 mg/DL or blood pressure < 90/60 or > 185/110 mmHg on admission or Platelets < 100,000.

The investigators excluded pregnant and lactating patients and those with stroke due to venous thrombosis and stroke following cardiac arrest or profuse hypotension ineligible for our trial.
