Old ‘NSTEMI’ A history of coronary artery disease and a stent to the same territory further increases pre-test likelihood of acute coronary occlusion, including in-stent thrombosis. The patient had a history of ‘NSTEMI’ a decade prior, with an RCA stent. Does this change your interpretation?

Introduction:Subacute stent thrombosis (ST) is related to high rates of cardiac reinfarction. The patient’s chest pain (CP) was not alleviated with initial revascularization of his left circumflex (LCx) ST, requiring PCI to his right coronary artery (RCA) chronic total occlusion (CTO).

You can easily imagine this patient getting one of several diagnoses -- vasospasm, MINOCA , pericarditis, or maybe even no diagnosis at all beyond "non-obstructive coronary artery disease." The operator documented thoughtful consideration of risks and benefits of stent placement.

Stone, MD Mount Sinai Health System tim.hodson Wed, 04/02/2025 - 15:26 March 31, 2025 Using intravascular imaging (IVI) to guide stent implantation during complex stenting procedures is safer and more effective for patients with severely calcified coronary artery disease than conventional angiography, the more commonly used technique.

Background Bioresorbable vascular scaffolds (BVS) were designed to reduce the rate of late adverse events observed in conventional drug-eluting stents (DES) by dissolving once they have restored lasting patency.

If the FFR normalizes after stenting, the restenosis rates at six months is less than 5%. Since the FFR wire can be used for guiding balloon catheters and stents, it is easy to make post procedure measurements without any additional effort. Routine FFR measurement probably lead to more judicious use of stents and improved outcomes.

In the early years of percutaneous coronary intervention (PCI), studies indicated a heightened risk of major adverse cardiac events (MACE) in patients with reduced left ventricular ejection fraction (LVEF), involving outcomes such as death, Q-wave myocardial infarction (MI), stent thrombosis, and repeat revascularization.

The primary non-inferiority endpoint was MACCE (a composite of cardiac death, MI, ischaemic stroke, stent thrombosis, or target vessel revascularisation). The results advocate for considering PCI as a treatment option for such plaques, potentially expanding the indications for PCI in coronary artery disease management.

After stent deployment, we often see improvement in the ST-T within seconds or minutes. Note the pressure on the arterial line, estimated at 45/25 mm Hg.
