OBJECTIVETo survey the treatment status and clinical features of hospitalized patients with acute myocardial infarction (AMI) of 13 hospitals in Beijing in 2005.

METHODSUniform questionnaires were used to register AMI patients hospitalized from January 1 to December 31, 2005 in the 13 hospitals including traditional Chinese medicine (TCM) hospitals (n = 6) and western medicine hospitals (WM, n = 7) from Beijing. A total of 1663 AMI patients were registered (1366 cases in WM hospitals and 297 cases in TCM hospitals). An Access database was established and patient information was input, the clinical features and treatment status of hospitalized AMI patients were analyzed.

RESULTSThe mean age was (63.9 +/- 12.8) years old [(62.8 +/- 12.8) years for WM Hospitals and (69.1 +/- 11.8) years for TCM hospitals, P < 0.05], male to female ratio was 2.4:1 (2.7:1 for WM hospitals and 1.6:1 for TCM hospitals, P < 0.05). The median time to hospital was 14 hours in TCM hospitals and 11 hours in WM hospitals (P > 0.05). Incidences of history of cerebrovascular disease, high blood pressure, diabetes, hyperlipidemia and complications such as in-patient arrhythmia, cardiac insufficiency, cardiogenic shock were significantly higher in TCM hospitals than in WM hospitals. The total mortality of 1663 AMI cases was 8.2% (15.8% in TCM hospitals vs. 6.6% in WM hospitals, P < 0.01). The reperfusion rate including emergency PCI and thrombolytic therapy rate was 31.3% in 13 hospitals (33.3% in WM hospitals vs. 21.9% in TCM hospitals, P < 0.05). Percent of guideline recommend drug use for AMI was as follows: aspirin 93.6%, ACEI and ARB 85.1%, beta-blocker 78.7%, low molecular weight heparin 85.4%, statins 74.7%.

CONCLUSIONSReperfusion therapy and guideline recommended drugs were widely used although there was a need for further improvement. The hospitalized mortality showed a downward trend compared with results from five years ago, patients in TCM hospitals had an independent clinical features.
