Primary percutaneous coronary intervention for unprotected left main disease in patients with acute ST-segment elevation myocardial infarction the AMIS (Acute Myocardial Infarction in Switzerland) plus registry experience.
This study sought to assess outcomes in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention (PCI) for unprotected left main (LM) disease. ⋯ Emergent LM PCI in the context of acute myocardial infarction, even including 12% cardiogenic shock, appears to have a remarkably high (89%) in-hospital survival. Concurrent LM and non-LM PCI has worse outcomes than isolated LM PCI.

Randomized Controlled TrialComparison of titanium-nitride-oxide-coated stents with zotarolimus-eluting stents for coronary revascularization a randomized controlled trial.
This study sought to compare the efficacy of passive stent coating with titanium-nitride-oxide (TiNO) with drug-eluting stents releasing zotarolimus (ZES) (Endeavor, Medtronic, Minneapolis, Minnesota). ⋯ Compared with TiNO, ZES was superior with regard to late loss and binary restenosis. The concept of passive stent coating with TiNO remains inferior to drug-eluting stent technology in reducing restenosis. ([TIDE] Randomized Trial Comparing Titan Stent With Zotarolimus-Eluting Stent: NCT00492908).

Multicenter StudyPercutaneous coronary intervention of unprotected left main coronary artery disease as culprit lesion in patients with acute myocardial infarction.
This study sought to evaluate short- and long-term outcomes of patients undergoing emergency percutaneous coronary intervention (PCI) for acute myocardial infarction due to a culprit lesion in an unprotected left main coronary artery. ⋯ Patients with acute myocardial infarction and thrombosis of the unprotected left main coronary artery are a high-risk subgroup with a substantial mortality, particularly if they present in cardiogenic shock. We demonstrate that in these patients, PCI is a feasible treatment option associated with reasonably good outcomes. Long-term prognosis is excellent in hospital survivors with an 89.5% survival rate at 1 year.

Randomized Controlled Trial Multicenter StudyRandomized comparison of pre-hospital-initiated facilitated percutaneous coronary intervention versus primary percutaneous coronary intervention in acute myocardial infarction very early after symptom onset: the LIPSIA-STEMI trial (Leipzig immediate prehospital facilitated angioplasty in ST-segment myocardial infarction).
This multicenter trial sought to assess the merits of facilitated percutaneous coronary intervention (PCI) versus primary PCI in an ST-segment elevation myocardial infarction (STEMI) network with long transfer distances in patients presenting early after symptom onset. ⋯ In STEMI patients presenting early after symptom onset with relatively long transfer times, a fibrinolytic-based facilitated PCI approach with optimal antiplatelet comedication does not offer a benefit over primary PCI with respect to infarct size and tissue perfusion. ([LIPSIA-STEMI] The Leipzig Immediate Prehospital Facilitated Angioplasty in ST-Segment Myocardial Infarction; NCT00359918).

Impact of bleeding on mortality after percutaneous coronary intervention results from a patient-level pooled analysis of the REPLACE-2 (randomized evaluation of PCI linking angiomax to reduced clinical events), ACUITY (acute catheterization and urgent intervention triage strategy), and HORIZONS-AMI (harmonizing outcomes with revascularization and stents in acute myocardial infarction) trials.
This study sought to develop a risk score predictive of bleeding in patients undergoing percutaneous coronary intervention (PCI) and to investigate the impact of bleeding on subsequent mortality. ⋯ Non-CABG-related bleeding within 30 days is strongly associated with an increased risk of subsequent mortality at 1 year in patients undergoing PCI for all indications. A risk score was established to calculate the bleeding risk for patients undergoing PCI, allowing therapeutic decision making to minimize the incidence of bleeding.
