Details and patient eligibility

About

  1. Clopidogrel resistance is common in patients of ischemic cerebrovascular disease.
  2. Genetic polymorphisms are the most important factors to clopidogrel resistance.
  3. The purpose of this study is to find the genes which are the related to clopidogrel resistance.
  4. Through gene sequencing, we can filter patient of clopidogrel resistance, so another drug maybe used to avoid the undesired efficacy.
