Concomitant Use of Clopidogrel With Atorvastatin or Rosuvastatin in Patients With Small Vessel Stroke

Concomitant Use of Clopidogrel With Atorvastatin or Rosuvastatin in Patients With Small Vessel Stroke, a Randomized Controlled Single-blinded Trial

Along with the current clinical trial, the impact of adding atorvastatin or rosuvastatin in the first 24 hours on the clinical outcomes of first-ever small vessel stroke patients treated with clopidogrel and aspirin assessed through NIHSS, mRS, and possible adverse effects.

Study Overview

• Status: Recruiting
• Conditions: Ischemic Stroke
• Intervention / Treatment: Drug: Rosuvastatin 20mg; Drug: Atorvastatin 40mg

Detailed Description

The investigators will conduct a randomized controlled trial between April 2024 and April 2025 after the ethics committee of the faculty of medicine at Kafr el-Sheik University approves.

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 atorvastatin arm, which consisted of 300 patients who received 40 mg daily atorvastatin for 3 months, and the rosuvastatin arm consisted of 300 patients who received 20 mg rosuvastatin daily for 3 months, All the patients in the two groups received open-label clopidogrel at a loading dose of 300 mg and then 75 mg daily till the end of the 3 months.

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& TOE: in indicated patients ECG Monitoring: daily ECG monitoring will be performed in indicated patients. - 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 stroke at 90 days

• 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 the 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 acute liver injury assessed by ALT, AST test at 90 days, statin-induced myopathy assessed by CPK at 90 days and other adverse effects assessed by a follow-up questionnaire.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
the rate of new stroke at 90 days	Rates of new ischemic stroke occur within three months of treatment. The investigators will perform follow-ups of the patient during visits to the outpatient clinic, and brain CT and/ or MRI will be done if there is suspicion of recurrence of ischemic stroke.	90 days

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
rate of drug adverse effects	Drug adverse effects: all side effects related to the drugs of our study will be reported	90 days
Value of National Institute of Health Stroke Scale (NIHSS) after one week	NIHSS is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke and aid in planning post-acute care disposition. It ranges from 0 to 42; the lower the score, the better the stroke condition. The improvement will be counted only if there is a decrease in NIHSS score by four points or more within one week of stroke onset.	7 days
value of Modified Rankin Scale (mRS) at one week	mRS Measures the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability its value ranges from 0 to 6; the lower the score, the better the stroke outcome favorable stroke outcome is considered with mRS value equals two or less.	7 days
value of Modified Rankin Scale(mRS) at three months	mRS Measures the degree of disability or dependence in the daily activities of people who have suffered a stroke or other causes of neurological disability its value ranges from 0 to 6; the lower the score, the better the stroke outcome favorable stroke outcome is considered with mRS value equals two or less.	3 months
rate of composite recurrent stroke, myocardial infarction, and death due to vascular events	rates of new ischemic stroke, TIA, myocardial infarction, or death from vascular events within three months of treatment the investigators will perform follow-ups of the patient during visits to the outpatient clinic and perform needed investigations such as brain imaging, Electrocardiography, arterial and venous duplex ultrasound imaging.	3 months
Drug adverse effects: all side effects related to the drugs of our study will be reported	the rate of drug hemorrhagic complications which was evaluated using the PLATO bleeding definition which classified hemorrhagic complications into three types as follows: Major bleeding which had one or more of the following criteria: fatal bleeding, intracranial, intrapericardial, bleeding associated with reduction of hemoglobin > 3-5 g/dl, bleeding required transfusion of two to four units whole blood or PRBCs, bleeding produced hypovolemic shock or severe hypotension that required pressor or surgery; Minor bleeding that required medical intervention to stop or treat bleeding: Minimal bleeding: any bleeding that did not require intervention or treatment such as bruising, bleeding gums, oozing from injection sites.	90 days
