[Pathogenic factors and prognosis of non cardiac inpatients with acute myocardial infarction].

Objective: To collect the clinical data of non-cardiac inpatients with coronary heart disease risk factors and analyze the pathogenic factors and prognosis features of these inpatients with acute myocardial infarction.

Methods: Retrospective analyses were performed for 650 cases of consecutive non-cardiac inpatients with coronary heart disease risk factors at Tianjin Union Medical Center between January 2009 and January 2012.They were divided into non myocardial infarction (UnAMI, n = 551) and myocardial infarction groups (AMI, n = 99).

Coronary plaque composition of culprit/target lesions according to the clinical presentation: a virtual histology intravascular ultrasound analysis.

Aims: To evaluate the plaque composition obtained by virtual histology (VH) IVUS according to the clinical presentation and to compare those data to previously published histopathology data.

Methods And Results: VH was performed on 95 de novo significant lesions (>75% stenosis) in 85 patients [28 acute coronary syndrome (ACS) patients, 30 lesions; 57 stable angina pectoris (SAP) patients, 65 lesions]. There were a higher prevalence of positive remodelling (47 vs.
