Objectives We investigated the effectiveness of clopidogrel loading (CL) treatment compared with usual clopidogrel non-loading (NL) treatment for acute ischemic cerebrovascular disease. Methods We screened consecutive 1072 patients with ischemic cerebrovascular disease within 48 hours of symptom onset admitted to our hospital. Eligible patients were divided into the CL group (300 mg on day 1, followed by 50-75 mg once daily) and NL group (50-75 mg once daily). The incidence proportion of neurologic deterioration during hospitalization was compared between the 2 groups using logistic regression analysis. Results A total of 224 patients, 39 in CL group and 185 in NL group, were enrolled. The frequency of neurologic deterioration did not significantly differ between the 2 groups (risk ratio [95% confidence interval]: 1.47 [.88-2.46]). On the preset subgroup analysis according to stroke subtype, the frequency of neurologic deterioration in CL group was significantly higher in branch atheromatous disease (risk ratio: 2.44 [1.67-3.55]) and was not different statistically in transient ischemic attack (risk ratio: 0). The analysis adjusted by several confounders showed that the incidence proportion of neurologic deterioration was not significantly different in large artery atherosclerosis (adjusted odds ratio: 1.06 [.23-4.84]) as crude analysis. The incidence proportion of adverse events was not significantly different between the 2 groups. Conclusions The effect of CL therapy differed by stroke subtypes in preventing neurologic deterioration. CL therapy appeared to be ineffective in branch atheromatous disease. Therefore, the choice of CL therapy should carefully be made according to stroke subtypes.
