Correlation Analysis of Pulse Wave Velocity and Severity of Coronary Heart Disease

Objective To investigate the correlation of the pulse wave velocity and severity of coronary heart disease, and evaluate the predictive value. Methods 180 patients with coronary artery disease were enrolled as coronary disease group, which were devided into single-vessel group(n = 119) and multi-vessel group(n = 61) according to the lesion number,and into slight lesion group(n = 132) and severe lesion group(n = 48) according to the severity. 180 healthy people were chosen as healthy group in the corresponding period. The differences of pulse wave velocity between healthy group and coronary disease group, single-vessel group and multi-vessel group, slight lesion group and severe lesion group were analyzed. Res ults The pulse wave velocity of coronary disease group was apparently higher than that of healthy group, and the difference had statistical significance(P 0.05). The pulse wave velocity of multi-vessel group was obviously higher than that of single-vessel group, and the difference had statistical significance(P 0.05). The pulse wave velocity of slight lesion group was much lower than that of severe lesion group, and the difference between them was statistically significant(P 0.05). Conclus ion The pulse wave velocity and the severity of coronary heart disease have a significant correlation, which patients with more severe disease have higher pulse wave velocity.
