    Optical coherence tomography in ST-elevation myocardial infarction treated with novel drug-eluting stent: preprocedural, post implant and 2-month follow-up findings
    The use of drug-eluting stents (DES) allowed the reduction in the need for repeat revascularization. At the culprit site in acute myocardial infarction patients treated with first-generation DES, the interaction between the eluted drug and the underlying necrotic core may generate different patterns of pathologic vessel response and delayed healing. A new generation DES intrepide elutes trapidil. Its modes of action are neither cytotoxic nor cytostatic, and may promote normal re-endothelialization. Due to its high resolution, optical coherence tomography (OCT) allows accurate detection of thrombus deposition and stent strut coverage at follow-up. Intravascular ultrasound (IVUS) has enhanced tissue penetration and ...
