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.

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.

30-day readmissions after coronary artery bypass graft surgery in New York State.
The aim of this study was to identify reasons for and predictors of readmission. ⋯ The 30-day readmission rate for CABG surgery remains high, despite decreases in short-term mortality. Patients with any of the numerous risk factors for readmission should be closely monitored. Hospital readmission rates are not highly correlated with mortality rates and might serve as an independent quality measure.

The relationship between volumetric plaque components and classical cardiovascular risk factors and the metabolic syndrome a 3-vessel coronary artery virtual histology-intravascular ultrasound analysis.
The aim of this study was to analyze volumetric plaque composition of the coronary arterial tree according to the classical cardiovascular risk factors and metabolic syndrome (MS) using virtual histology-intravascular ultrasound (VH-IVUS). ⋯ Three-vessel VH-IVUS analysis showed that DM and MS patients, compared to patients without DM or MS, had a larger plaque-plus-media burden, larger amount of NC, and more frequent VH-IVUS-derived thin-cap fibroatheromas in coronary arterial trees, implying greater plaque vulnerability in DM and MS patients.
