Abstract:

Objective To observe aspirin & clopidogrel resistance-related gene polymorphisms, and to explore their relations with recurrent cerebral infarction. Methods A total of 98 cerebral infarction patients were selected from the Department of Neurology in our hospital from April 2019 to December 2020, and the relations between aspirin & clopidogrel resistance-related gene polymorphisms and gender & recurrent cerebral infarction were retrospectively analyzed. Results In patients suffering from cerebral infarction, patients severely resistant to aspirin were more likely to have recurrent cerebral infarction on standard anti-platelet therapy than sensitive patients (P<0.05); the patients suffering from the moderate/severe resistance to aspirin with medium/slow metabolism of clopidogrel complicated were more likely to have recurrent cerebral infarction than aspirin sensitivity and (or) fast metabolism of clopidogrel (P<0.05). The difference in the proportion of different clopidogrel drug-related gene phenotypes wasn’t statistically significant (P>0.05); and the difference in the distribution of aspirin & clopidogrel resistance-related phenotypes with different genders wasn’t statistically significant (P>0.05). Conclusion It is crucial to test aspirin & clopidogrel resistance-related phenotypes in the treatment of cerebral infarction, and it is necessary to appropriately adjust the therapeutic regimen according to test results to improve the therapeutic effects on cerebral infarction.
