Abstract:
Objective: Based on scores by number of vessels diseased and age (NVDA), the minimum lumen area (MLA) of left anterior descending (LAD) proximal or middle intermediate lesions were examined by intravascular ultrasound (IVUS) to analyze the clinical characteristics, to ifnd the factors affecting lumen area and to establish a scoring system for predicting MLA in relevant patients.
Methods: A total of 90 patients were enrolled including 58 male and 32 female with the age of (41-77) years. The demographic information, medical history and laboratory results were studied by simple linear regression analysis to screen relevant factors affecting MLA; multi regression analysis was conducted to establish a regression equation for predicting MLA and to calculate the risk factor coefifcient for obtaining relevant scoring system.
Results: NVDA score≤4 was deifned as negative result with speculated MLA≥3.0mm2, while NVDA score>4 was deifned as positive result with speculated MLA<3.0mm2. The sensitivity, speciifcity and negative predictive value of NVDA scoring system for predicting MLA were 83.35%, 75% and 90% respectively.
Conclusion: NVDA scoring system had the better accuracy, sensitivity and speciifcity for predicting MLA in coronary artery intermediate lesions, it had certain value for guiding coronary interventional therapy in relevant patients.
