Abstract:To analyze the clinical characteristics of Danshen Chuanxiongqin injection in the treatment of cerebrovascular diseases in the real world.Methods:Frequency analysis and association rule analysis were performed with the information of 4 400 patients with cerebrovascular diseases from the information systems of 21 grade A tertiary hospitals in China.Results:The patients treated with Danshen Chuanxiongqin injection had an average age of 67.62 years and were mainly male(2 533 patients,accounting for 62.95%).Cerebral infarction was the most common cerebrovascular disease(2 501 patients,49.14%).The main single drugs for combined application with Danshen Chuanxiongqin injection were acetylsalicylic acid(2 479 patients,3.12%),protolysate(1 733 patients,2.18%),and atorvastatin(1 636 patients,2.06%).The main two drugs for combined application were oral preparation of Ginkgo Folium+protolysate.The common combination of single Chinese medicine+single western medicine was the agent for activating blood to remove stasis+blood substitute and perfusion fluid.The common combination of single Chinese medicine+two western medicines was the agent for activating blood to remove stasis+western medicine for heart disease+blood substitute and perfusion fluid.The common combination of single Chinese medicine+three western medicines was the agent for activating blood to remove stasis+western medicine for heart disease+blood substitute and perfusion fluid+western medicine for oral disease.Conclusion:Danshen Chuanxiongqin injection was mainly applicable for the elderly and often combined with the agent for activating blood to remove stasis,blood substitute and perfusion fluid,medicine for heart disease,and medicine for oral disease in clinical practice.The clinical application dosage of Danshen Chuanxiongqin injection was different from the drug instructions,so clinicians should be cautious about it.This study provides a reference for the clinical use of Danshen Chuanxiongqin injection.
