Electrocardiographic lead aVR is usually ignored in patients with chest pain. ST segment elevation in aVR may have diagnostic value in patients with acute coronary syndrome (ACS) and significant stenosis or obstruction of the left main coronary artery (LMCAS), especially when accompanied by ST segment elevation in lead V(1). ⋯ The assessment of lead aVR in patients with ACS may indicate LMCAS. Additional analysis of lead V(1) does not improve diagnostic accuracy.

The majority of studies demonstrating the diagnostic potential of three-dimensional (3D) echocardiography have been conducted on selected series of patients in research laboratories. ⋯ RT 3D TTE may be used in clinical settings with high feasibility rate and provides additional, clinically relevant qualitative information. The lack of on-board quantitative analysis tools is the main limitation of the currently available system.

Comparative Study
Primary coronary angioplasty in patients with ST segment elevation acute myocardial infarction and diabetes.
Subjects with diabetes constitute 13-25% of patients with ST segment elevation acute myocardial infarction (STEMI). In spite of the introduction of thrombolytic therapy, patients with STEMI and diabetes continue to have worse prognosis than those without diabetes. Primary percutaneous coronary intervention (PCI) has been shown in recent years to be the most effective therapy in patients with STEMI. ⋯ Primary PCI-achieved epicardial and myocardial reperfusion rate is lower in STEMI patients with rather than without diabetes. The presence of diabetes almost doubles the risk of MACE during a six-month follow-up.
