Correlation of Different Indexes of Arterial Elastic Function / 中华高血压杂志

ABSTRACT

Objective To study the correlation of three different indexes of arterial elastic function(PWV, C_ 1 and C_ 2 , AI). Methods 1306 out-patients with hypertension were recruited. Two or three arterial elastic function were measured at the same time. Large and small arterial elastic indexes(C_ 1 and C_ 2 );pulse wave velocity(PWV)and augmentation index (AI) in 428 cases , C_ 1 , C_ 2 and PWV(n=208), C_ 1 , C_ 2 , PWV and AI(n=60). Results C_ 1 was negatively related to PWV and positively related with C_ 2 . No correlation between AI and PWV, AI and C_ 1 and C_ 2 was found. Conclusion PWV, C_ 1 and C_ 2 are consistent for the arterial elastic function measurement. However, little relevance between AI and PWV, AI and C_ 1 and C_ 2 was shown.
