Normal coronary arteries: clinical implications and further classification.

abstract：:Over the past decade there has been a steady proliferation of indices which have been proposed for assessing ventricular function. Many of these indices are based on single measurements and often are insensitive and have limited clinical utility. The present article focuses on the role of wall stress in assessing vent...
