title: [Complication rates and secondary interventions after coronary procedures in clinical routine: 1-year follow-up based on routine data of a German health insurance company].
abstract: BACKGROUND
  Data on 1-year complication and follow-up intervention rates after coronary angiography (CA) and percutaneous coronary intervention (PCI) in German clinical routine are sparse. This analysis aims to determine these rates.
  
  
  METHODS
  The analysis uses 2009 AOK claims data. Patients were divided into 3 groups (CA, without cardiac surgery and without acute myocardial infarction (AMI) n=116.071; PCI with stenting, without AMI: n=36.685; PCI with stenting and with AMI: n=32.707). The frequency of the endpoints MACCE (mortality, AMI, stroke, TIA), CABG, PCI and CA was recorded for up to one year.
  
  
  RESULTS
  1-year MACCE rates were 8.1 % (CA), 9.9 % (PCI without AMI) and 17.9 % (PCI with AMI). Quality-relevant follow-up intervention rates in the CA group were 2.5 % for CABG (after 31-365 days), 1.7 % for PCI within 90 days and 3.5 % for follow-up CA within 1 year. In the PCI groups, the frequencies were 1.6 % (without AMI) and 2.7 % (with AMI) for CABG (after 31-365 days), and 10.2 % (without AMI) and 10.1 % (with AMI) for PCI after 91-365 days.
  
  
  CONCLUSIONS
  This is the first cross-sectoral routine analysis of cardiac catheters and sequential events up to one year in Germany. The actual medical care situation revealed information particularly with regard to the second and follow-up inventions, which cannot be derived directly from medical guidelines. Beyond clinical trials, knowledge can be gained which is important both for medicine as well as the politics of health services.
