Description
Introduction This analysis examines the influence of age on antithrombotic therapy, success rate of percutaneous coronary intervention (PCI) and in-hospital mortality in patients with Acute Coronary Syndrome (ACS) and elective PCI. Methods We analysed data of 26,795 unselected patients with ST-elevation myocardial infarction (STEMI), non-STelevation myocardial infarction (NSTEMI), unstable Angina (UA) and elective PCI from the ALKK-PCI Registry 2006, a German prospective, multicentre registry. Results Elderly patients ([75) with ACS were significantly less often treated with acetylsalicylic acid intravenously and a clopidogrel loading dose of 600 mg. Moreover, the administration of GP IIb/IIIa antagonists was significantly lower in these patients. The rate of successful PCI (indicated as TIMI 3 flow) is comparable in younger and elderly patients with elective PCI, UA and NSTEMI, whereas there were more unsuccessful interventions in elderly patients with STEMI (13.2 vs. 11.0%, p\0,033). In all indications elderly patients showed increased in-hospital mortality. Conclusion In clinical practice, elderly patients with ACS undergoing PCI receive significantly less intensive antithrombotic treatment. In terms of successful PCI, there was no significant difference between the age groups in patients with elective PCI, UA and NSTEMI. The higher in-hospital mortality of the elderly in all patient groups is most likely due to a higher rate of comorbidities.
