Abstract: 【ABSTRACT】Objective: To investigate the brachial ankle pulse wave conduction velocity (baPWV) combined with ultrasound echocardiography the significance of detection of figure in the functional abnormality of the coronary heart disease (CHD) and cardiac remodeling. Methods: 286 patients with CHD were divided into two groups (experimental group, 150 cases) and CHD normal configuration group (control group, 136 cases) according to echocardiography. The two groups of BaPWV and cardiac function parameters were analyzed and compared. Results: Compared with the two groups of patients with basic information and baPWV, baPWV in experimental group was significantly higher than that of control group, arterial stiffness was higher in two groups compared with statistical significance, P ＜0.01; experimental group, left ventricular diastolic final diameter, left ventricular septal thickness, left ventricular relative wall thickness,left ventricular wall thickness, left ventricular mass index (LVMI), mitral diastolic early peak flow velocity of mitral valve, late diastolic peak flow velocity, E / a ratio, left ventricular ejection fraction cardiac function parameters and control group had statistical significance compared, P＜0.05. BaPWV and the parameters of cardiac function relevance. Conclusion: The combined detection of BaPWV and echocardiography plays an important role in the prevention of cardiac dysfunction and cardiac remodeling in patients with CHD. BaPWV is an independent risk factor for cardiac remodeling and cardiac dysfunction in patients with CHD.
