title: [Current status of medical therapy of chronic stable angina pectoris in mainland of China: the second survey].
abstract: OBJECTIVE
  To investigate the current status of medical treatments for patients with chronic stable angina pectoris (SA) and the gaps between clinical practice and guidelines in mainland of China.
  
  
  METHODS
  This was a multicenter cross-sectional survey. Each investigator enrolled at least 50 consecutive outpatients with SA who were diagnosed and treated for at least one month. A standardized questionnaire including information on patients characteristics, risk factors, complicating diseases and current medication was filled out by investigator for each individual patient.
  
  
  RESULTS
  One thousand eight hundred and thirty questionnaires were collected from 29 hospitals and 1809 intact records were used for final analysis. Mild and moderate angina (CCS I or II) were still present in 79.6% patients, 91.3% patients were treated with aspirin, 37.4% with clopidogrel, 64.6% with β blocker, 50.3% with angiotensin-converting enzyme inhibitor (ACEI), 20.1% with angiotensin II receptor blocker (ARB), and 65.3% with statin.
  
  
  CONCLUSIONS
  In general, guidelines were followed in the medical treatments of SA in the mainland of China and improved compared with the survey data obtained 10 years ago; however, there are still gaps between current clinical practice and guidelines, the insufficient use of β-blocker and statin for SA patients is especially significant.
