Acute Myocardial Infarction in Chinese Medicine Hospitals in China from 2006 to 2013: An Analysis of 2311 Patients from Hospital Data / 中国结合医学杂志

ABSTRACT

OBJECTIVE@#To assess the trends in characteristics, treatments, and outcomes of acute myocardial infarction (AMI) patients in tertiary Chinese medicine (CM) hospitals in China between 2006 and 2013.@*METHODS@#This retrospective study was based on two nationwide epidemiological surveys of AMI in tertiary CM hospitals during 2 years (2006 and 2013). Patients admitted to the hospital for AMI were enrolled. Hospital records were used as the data source. Case data were derived regarding baseline characteristics, treatments, and outcomes of patients to assess changes from 2006 to 2013. Logistic regression was used to analyze the relationship between prognosis, general influencing factors of disease, and various treatment measures.@*RESULTS@#Totally 26 tertiary CM hospitals in 2006 and 29 tertiary CM hospitals in 2013 (18 were repetitive) were surveyed. A total of 2,311 patients with AMI were enrolled (1,094 cases in 2006 and 1,217 cases in 2013). From 2006 to 2013, the mean age did not significantly change, but the proportion of patients younger than 65 years increased. The prevalence of risk factors such as hypertension, diabetes, and hyperlipidemia also increased. Significant increases were observed in primary percutaneous coronary intervention [20.48% (2006) vs. 24.90% (2013)] and revascularization [36.11% (2006) vs. 52.42% (2013)]. In-hospital mortality decreased from 11.15% in 2006 to 10.60% in 2013. A mortality logistic regression analysis identified reperfusion therapy [odds ratio (OR), 0.222; 95% confidence interval (CI), 0.106-0.464], Chinese patent medicines (OR, 0.394; 95% CI, 0.213-0.727), and CM decoctions (OR, 0.196; 95% CI, 0.109-0.353) as protective factors.@*CONCLUSION@#Reperfusion and revascularization capabilities of tertiary CM hospitals have improved significantly, but in-hospital mortality has not significantly decreased. Efforts are needed to improve medical awareness of AMI and expand the use of CM to reduce in-hospital mortality in China.
