- Abstract
- Background
The purpose of this study is to identify the differences of risk factors and stroke mechanism between early
and late recurrence in patients with long-term antiplatelet therapy for stroke prevention.
Methods
We enrolled 114 consecutive patients with recurrent infarction who had been taking antiplatelet agents
regularly since previous noncardioembolic cerebral infarction. Total 81 patients (49 men and 32 women) were met to the
inclusion criteria through standardized evaluation. Subjects were classified into two groups depending on the
time-to-recurrence after antiplatelet therapy: early antiplatelet failure (within 2 years, n=41, hereafter as “EAF”) and later
antiplatelet failure (after 2 years, n=40, hereafter as “LAF”). We investigated the differences of clinical factors between
two groups using univariate and multivariate analysis.
Results
Family history of stroke (29.3% in EAF vs. 10% in LAF, p=0.029) was more frequent in EAF group. Low
HDL-cholesterol and High total cholesterol/HDL-cholesterol ratio were associated with the LAF group (p=0.042, 0.005
respectively). Multivariate analysis showed that family history of stroke (OR=5.283, 95%CI 1.178-23.699, p=0.030) and
previous infarction classified as large artery atherosclerosis (OR=8.497, 95%CI 1.444?50.015, p=0.018) were significant
predictors for EAF whereas total cholesterol/HDL-cholesterol ratio (OR=2.002, 95%CI 1.183?3.389, p=0.010) was for LAF.
Conclusions
This study suggests that family history of stroke and cerebral infarction due to large artery atherosclerosis
are more responsible for the early recurrence while dyslipidemic condition is more related to the late recurrence during
long-term antiplatelet therapy in patients with previous cerebral infarction. Key Words: Antiplatelet agent, Infarction, Recurrence, Treatment failure
