29

Results

FMD in brachial artery was similar between at baseline and after 6 months in the control group. In contrast, FMD significantly increased from baseline to 7 after 6 months in the cilostazol group ( p = 0.019).

Baseline Characteristics

This study was conducted at the Tokyo Women's Medical University Hospital from December 2014 to March 2017. We selected the patients taking clopidogrel enrolled in the CSPS.com study in our hospital. They were randomly assigned to two group; cilostazol plus clopidogrel (CIL group), and clopidogrel without cilostazol (control group) centrally through a web-based registration system. The eligibility criteria of CSPS.com study was a non-cardioembolic ischemic stroke between 8 days and 180 days since stroke onset. They were required to take either aspirin or clopidogrel alone and meet at least one of the following three criteria: at least 50% stenosis of a major intracranial artery, at least 50% stenosis of an extracranial artery, and two or more vascular risk factors.

Participant flow

Endothelial function was assessed by measuring FMD of the brachial artery in response to hyperemia according to methods previously described. FMD was shown to be related to several vascular risk factors such as blood pressure level and a significant predictor of cardiovascular events. The subjects were studied in a quiet and temperature-controlled room, from 9 to 11 AM. The extent of FMD in the brachial artery was measured by ultrasonography using a high-resolution ultrasound system equipped with a 10-MHz linear array transducer. The subjects were placed in the sitting position with their right arms in a comfortable position for the examination. A segment with clear anterior and posterior intimal interfaces between the lumen and vessel wall was selected for continuous 2D grayscale imaging at rest. Thereafter, arterial occlusion was created by forearm-cuff inflation to at least 50 mmHg above systolic blood pressure for 5 min before release. After deflation of the cuff, the diastolic diameter of the brachial artery was semi-automatically recorded continuously for 3 min. FMD is defined as the maximal percent change in brachial artery diameter after reactive hyperemia compared with the baseline. FMD was performed at baseline and at 6 months after randomization.
