Conclusions
CMD
In conclusion, our study suggests that direct stenting, aspiration thrombectomy, and intracoronary injection of glycoprotein IIb/IIIa inhibitors each is associated with a lower prevalence of CMD at 3 months and lower incidence of MACE at 12 months when compared with balloon pre-dilatation before stenting. Further research is needed to confirm our results in larger, randomized trials conducted across multiple institutions.
