OBJECTIVE: To investigate the potentially inappropriate medication（ PIM） and influencing factors in elderly patients in cardiology

and to explore the medication crisis management measures for elderly patients in cardiology. METHODS: A total of 300 elderly patients were randomly selected from the cardiology department of General Hospital of Eastern Theater Command of Chinese People’s Liberation Army from Aug. 2019 to Nov. 2020.PIM was evaluated according to STOPP/START criteria（ 2014 Edition）

and the influencing factors of PIM in elderly patients in cardiology were analyzed by Logistic regression. RESULTS: Among the 300 patients

there were 235 cases of PIM

104 case-times with STOPP criteria and 271 case-times with START criteria

and there were cases of PIM combined with multiple STOPP/START criteria. Univariate analysis showed that age

number of diseases

drug combination

history of cardiovascular diseases and antithrombotic therapy were correlated with the occurrence of PIM in elderly patients in cardiology（ P <0. 05）. Logistic regression analysis showed that atrial fibrillation

stable angina

coronary atherosclerosis

drug combination and antithrombotic therapy were risk factors for PIM（ P < 0. 05）.CONCLUSIONS: The influencing factors of PIM in elderly patients in cardiology mainly include atrial fibrillation

stable angina

coronary atherosclerosis

drug combination（ from 11 to 21） and antithrombotic therapy. Medication crisis management measures such as standardizing the classification and storage of drugs

improving cardiology medication according to STOPP/START criteria

and standardizing the cardiology medication process are of positive significance in reducing the risk of PIM in elderly patients in cardiology.
