To identify clinical characteristics associated with the minimum lumen area (MLA) of proximal or middle intermediate lesions in left anterior descending (LAD) artery, and to develop a model predict MLA.We retrospectively analyzed demographic data, medical history, intravascular ultrasound findings for 90 patients LAD artery. Linear regression was used factors affecting MLA, multiple predicting MLA.Age, number lesions, diabetes mellitus correlated significantly MLA lesions. A (mm(2)) derived from data: 7.00 - 0.05 × (age) 0.50 (number lesions). cut-off value 3.1 mm(2) proposed deciding when perform percutaneous coronary intervention.This artery showed high accuracy, sensitivity, specificity, indicating good diagnostic potential.
