Aim: to assess safety and efficacy of single stage complete revascularization by multivessel stenting as primary percutaneous coronary intervention (pPCI) in elderly and middle aged patients with acute ST-elevation myocardial infarction (STEMI).
Material and methods: We included in this analysis data on 327 of 1690 STEMI patients who had undergone pPCI from 2009 to 2013. Age of 103 patients was more or equal 65 and of 224 less or equal 64 years. Multivessel stenting (MS) during pPCI was carried out in 26 and 65, while strategy of staged revascularization (SR) was implemented in 77 and 129 individuals among older and younger patients, respectively. During follow-up for 12 months we registered deaths, myocardial infarctions, and unplanned target vessel revascularizations.
Results: In each age group ( more or equal 65 and less or equal 64 years) there were no significant differences in clinical and demographic characteristics between subgroups of patients subjected to MS and SR. MS appeared to be safe and effective irrespective of age. Mortality during first 30-days was higher among patients aged more or equal 65 years. However, within each age group there were no significant differences in 1 year results between MS and SR subgroups.
