Revisiting the Efficacy and Safety of Bivalirudin in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Percutaneous Coronary Intervention: Insights From a Mixed Treatment Comparison Meta-Analysis of Randomized Trials.

Background: Randomized trials of bivalirudin in patients with ST elevation myocardial infarction (STEMI) have yielded heterogeneous results.

Aims: Our aim was to evaluate the efficacy and safety of four antithrombin regimens-unfractionated heparin (UFH), bivalirudin (stopped soon after percutaneous coronary intervention [PCI]), extended bivalirudin (continued for a few hours after PCI), and combined UFH and a Gp2b3a inhibitors (GPI) in patients who present with STEMI.

Methods: A PubMed, EMBASE, and clinicaltrials.

Novel approach to stenting the left anterior descending coronary artery through a retrograde approach via the left internal mammary artery graft in a patient with occlusion of the coronary ostium from a prior aortic valve replacement.

Total occlusion of both coronary ostia is a rare and potentially life-threatening complication following surgical aortic valve replacement. This report presents a case of a patient with known total occlusion of both coronary artery ostia following combined coronary artery bypass graft surgery and aortic valve replacement who underwent successful percutaneous coronary intervention through a retrograde approach.

Major Adverse Cardiovascular Events After Colchicine Administration Before Percutaneous Coronary Intervention: Follow-Up of the Colchicine-PCI Trial.

Periprocedural inflammation is associated with major adverse cardiovascular events in patients who undergo percutaneous coronary intervention (PCI). In the contemporary era, 5% to 10% of patients develop restenosis, and in the acute coronary syndrome cohort, there remains a 20% major adverse cardiovascular events rate at 3 years, half of which are culprit-lesion related. In patients at risk of restenosis, colchicine has been shown to reduce restenosis when started within 24 hours of PCI and continued for 6 months thereafter, compared with placebo.

In-hospital Outcomes of Patients With and Without Previous Coronary Artery Bypass Graft Surgery Who Present With a Non-ST-Segment Elevation Myocardial Infarction.

The clinical course of patients with a previous coronary artery bypass graft surgery (CABG) presenting with non-ST-elevation myocardial infarction (NSTEMI) is not well defined. We aimed to compare the management and outcomes of patients with and without previous CABG who present with an NSTEMI. Patients hospitalized with an NSTEMI between 2002 and 2018 were identified from the National Inpatient Sample.

Toward Personalized DAPT: Is There an Inter-Manufacturer Difference in Generic Clopidogrel Response?

Objective: To compare rates of clopidogrel response among patients receiving medication produced by 2 different manufacturers after acute coronary syndrome (ACS) and/or percutaneous coronary intervention.

Methods: This quality-improvement project included 515 adult patients receiving clopidogrel for ACS or ischemic heart disease and referred for coronary angiography/ percutaneous coronary intervention. The project was divided into 2 phases: (1) retrospective collection of baseline data (April 2019-October 2020); and (2) two 12-week, prospective phases in which all clopidogrel in the hospital was restricted to a single manufacturer at a time (November 2020-May 2021).
