[Optical coherence tomography, delayed stent implantation and primary percutaneous coronary intervention in patients with myocardial infarction and ST segment elevation].
Primary percutaneous coronary intervention (PCI) is an effective treatment for myocardial infarction with ST-segment elevation. However, the stent may slow (slow-flow) or even interrupt the flow (no-reflow) in the infarct-related artery with an increase in short-term and long-term mortality. Due to these limitations there is an effort to search for alternative methods or certain modifications of existing PCI. ⋯ Control angiography and OCT done 9 months after event have revealed insignificant stenosis in all patients. It is plausible that universal medical procedure with stenting is not suitable for all patients with STEMI and especially patients with large thrombus may benefit from the alternative procedure performed by manually trombo-aspiration technique with intensive anticoagulant/antiaggregant therapy. Nevertheless, only randomized trials with sufficiently follow-up may confirm this hypothesis.
