Evaluation of PCI or Thrombolytic Therapy for Patients with Acute ST-segment Elevation Myocardial Infarction

OBJECTIVE:To study clinical efficiency and safety of the choice of PCI and thrombolytic therapy for patients with acute STEMI,and mak e a comparison between them.METHODS:By reviewing the literatures at home and abr oad.RESULTS:Thrombolytic therapy has been an important means of establishing rep erfusion in patients with acute ST-segment elevation myocardial infarction for d ecades.However,there are many limitations to the use of thrombolytic therapy,so primary percutaneous coronary intervention(PCI)has emerged as the preferred repe rfusion strategy.Primary PCI is superior to throm bolysis in reducing death, rein faretion,intracranial bleeding,recurrent ischemia,and reoeclusion of infaret ves sel.When PCI needs to be delayed several hours, thrombolytic therapy may be give n immediately after onset of the ST-segment elevation infaretion,and facilitate early reperfusion of infarct vessel.CONCLUSION:It is hopeful that a complete med ical care system that makes the best therapy available relatively prompt for ind ividuals who experience ST-segment elevation infarct,but prevention remains most important.
