P086 Characteristics and Socioeconomic Status of Patients undergoing Percutaneous Coronary Intervention with Stent Choice based on Patients' Willingness-to-Pay

Objective: To investigate peripheral arterial elasticity and wave intensity (WI) changes in patients with coronary artery disease (CAD). Methods: 26 cases of CAD patients with heart failure (HF group); 42 cases of non-heart failure patients (NHF group) and 40 healthy volunteers (control group) were involved in this study. ALOKA prosound a10 was employed to measure the indexes of the common carotid artery, including the first peak of carotid arterial (W1), the second peak (W2), the negative area of WI between the first and second peaks (NA), interval between the R wave of the ECG and the first peak (R-1st), interval between the first and second peaks (1st–2nd), Elasticity modulus (Ep), Stiffness parameter (b), Arterial Compliance (AC), Augmentation index (AI) and Pulse wave velocity (PWV). Comparison among the groups used the analysis of variance (ANOVA). Results: Elasticity of the carotid arteries in the NHF group and HF group were decreased. Compared with the control group, Ep, b and PWV were lower, AC was higher, and the differences were statistically significant (p 0.05). Conclusion: WI is a noninvasively obtained, clinically useful parameter for the evaluation of LV systolic and early diastolic performance, and WI reflected impaired cardiovascular function in CAD patients with a new perspective.
