Impact of time past from stemi onset to primary pci on periprocedural and short term results

摘要

We made retrospective analysis of 107 patients with ST segment elevation myo-cardial infarction (STEMI) admitted to our hospital from June 2007 to January 2009. The aim was to evaluate impact of time past between onset of symptoms and coronary intervention on efficacy of primary percutaneous coronary intervention (PCI) in these patients. The patients were divided into two groups depending to time past after onset of acute myocardial infarction (AMI): 1st group - 60 patients (56%) admitted during first 6 hrs and 2nd group - 47 patients (44%) admitted from 6 to 12hrs. The study revealed that primary PCI is especially effective when performed during first few hours after onset of AMI. Primary PCI performed after more than 6hrs after onset of symptoms may be related with more peri- or postprocedural complications and poorer prognosis.
