Deferred Stenting After Infarct-artery Opening May Limit MI Size
Holding off stent implantation for several days after patients have undergone thrombectomy, balloon angioplasty or both to open STEMI-related arteries may be safe and beneficial, especially in those with anterior-wall MI, suggests new research. The INNOVATION trial of 104 Korean patients showed that those who were randomly assigned to stenting three to seven days after their initial procedure for STEMI "had a strong tendency" toward reduction in infarct size (the primary end point) a month later, as well as reduced microvascular obstruction versus those who had received immediate stenting.
