OBJECTIVE: To investigate the application of antiplatelet drugs on patients with cardiovascular disease during hospitalization in Tianjin

so as to provide references for standardizing rational drug application.METHODS:Inpatients in department of cardiovascular in 10 hospitals in Tianjin from 2017 to 2020 were set as subjects

Epidata software was used to conduct data input

SPSS 26.0 was used for data collecting and analyzing.RESULTS: Totally1 178 patients were involved

of which 499 patients（ 42.4%） with angina pectoris

158 patients（ 13.4%） with acute myocardial infarction

131 patients（ 11.1%） with other types of diseases; the selection rate of antiplatelet drugs from high to low were respectively aspirin

clopidogrel

ticagrelor

tirofiban and cilostazol; the administration route of loading dose combination were mainly with aspirin and clopidogrel

but the loading dose application rate was low; the administration route of maintenance dose combination were mainly with aspirin and clopidogrel; there were differences in the characteristics of the medication behavior of different diseases

while there were also inconsistencies in characteristics of the medication behavior of same disease.CONCLUSIONS: There are differences in the medication behavior of inpatients with cardiovascular diseases in Tianjin in the drug selection

loading dose

maintenance dose and drug combination of antiplatelet drugs

the scientific and standardized treatment strategy still needs to be confirmed by large sample of real-world studies.
