Key result
In-stent restenosis is a progressive complication typically occurring 3 to 9 months after percutaneous coronary intervention, presenting as recurrent angina that requires clinical suspicion and specialized treatment.
Why the study?
Stent restenosis is a complex complication that many clinicians may underestimate or be unaware of.
This review highlights that in-stent restenosis should be considered a chronic, progressive stage in the coronary artery disease continuum, requiring clinical vigilance for recurrent angina and appropriate diagnostic workup.
Supports vigilance for recurrent angina 3-9 months post-PCI; leaves open optimal management of this chronic CAD stage.
Mortality rates from acute myocardial infarctions have been declining in the past 4 decades since percutaneous coronary interventions (PCIs) became a valid therapeutical option. PCI is a non-surgical revascularization procedure in which blood flow in an occluded or narrowed epicardial coronary artery is re-established by inflating an angioplasty balloon in order to remove the blockage, followed by the insertion of a stent in order to maintain the patency of the artery. Since the late ‘70s when the first bare metal stents (BMS) became available, progress has been made in developing new types of stents in order to lower the incidence of two important and feared complications: and thrombosis restenosis. While thrombosis is manageable and preventable with antithrombotic therapy, restenosis is a more complex issue of which many clinicians may not be aware or underestimate. The review would like to summarize the current knowledge from the literature on stent restenosis and present to clinicians some tools for recognizing, or at least suspecting, restenosis in their patients.

Munteanu et al. (2020) conducted a review in In-stent restenosis. Percutaneous coronary intervention was evaluated. In-stent restenosis is a progressive complication typically occurring 3 to 9 months after percutaneous coronary intervention, presenting as recurrent angina that requires clinical suspicion and specialized treatment.
