St Elevation Myocardial Infarction

CHICAGO — In the RIVAWAR trial, patients hospitalized for a heart attack who were treated with rivaroxaban for left ventricular thrombus had comparable outcomes at 3 months to patients treated with warfarin.

PHILADELPHIA — An artificial intelligence-enabled ECG was associated with shorter time from ECG to catheterization laboratory entry in patients with suspected STEMI, according the results of the ARISE study.

SAN FRANCISCO — A biodegradable polymer sirolimus-eluting stent remained superior to a durable polymer everolimus-eluting stent for treating STEMI at 5 years, a difference driven by lower rates of ischemia-driven repeat revascularizations.

Immediate PCI of nonculprit lesions during index hospitalization for STEMI was shown to be noninferior with fewer adverse events vs. a staged strategy addressing the nonculprit lesions after successful primary PCI, a speaker reported.

Among patients admitted for acute MI, intermediate- or high-risk frailty is associated with lower utilization of PCI, greater length of stays, greater total costs and higher 30-day readmissions, researchers reported.

Adults with HF after hospitalization for STEMI have lower serum iron levels compared with those without HF after STEMI, data from a retrospective case-control study show.

Treatment effect of the PCSK9 inhibitor alirocumab (Praluent, Sanofi/Regeneron) vs. sham control on LDL in patients with STEMI referred for primary PCI.

CHICAGO — A drug derived from traditional Chinese medicine as an adjunct to guideline-directed therapy improved CV outcomes at 30 days and 1 year compared with placebo after revascularization, with no excess bleeding risk, a speaker reported.

BOSTON — PCSK9 inhibition before primary PCI for STEMI, on top of standard statin therapy, significantly lowered LDL at 6 weeks compared with sham control, according to the results of the EPIC-STEMI trial presented at TCT 2022.

BOSTON — In the Healio video exclusive, Roxana Mehran, MD, discussed late-breaking research presented at TCT 2022, as well as the benefits of convening the meeting in person following the COVID-19 pandemic.
