Nonsignificant difference in Segmental Left Ventricular Dysfuncion between triple 50 and a single 75 Stenosis of the same Coronary Artery

摘要

We have been stressing the importance and the influence of a single 50% coronary artery stenosis on segmental left ventricular wall (LVW) systolic and diastolic dysfunctions. In this study the influence of multiple 50% stenosis of the same coconary artery on segmental LVW systolic and diastolic functions were analyzed. Total 288 coronary arteries were enrolled. There were significant difference of segmental LVW systolic and diastolic functions between normal and single 50% coronary artery stenosis (CAS), single and double 50% CAS, and double and triple 50% CAS. But there was no significant difference between triple 50% stenosis and single 75% stenosis.
