Abstract:【Objective】 To investigate the relationship of carotid artery ultrasound parameters with left ventricular diastolic function in patients with coronary heart disease.【Methods】 From January 2019 to March 2020, 24 patients with myocardial infarction treated in our hospital were included in the group A, and 30 patients with unstable angina and 26 patients with stable angina treated in the hospital in the same period were enrolled in the group B and group C, respectively. All patients in three groups received carotid ultrasound examination and left ventricular diastolic function measurement. The carotid artery ultrasound parameters [Common carotid artery stiffness (β), carotid artery compliance (AC), elastic coefficient (EP), pulse wave velocity (PEVβ)] and left ventricular diastolic function [Mitral valve E peak/Tissue Doppler E peak (E/Em), Mitral valve E peak/Left ventricular blood flow velocity (E/Vp), Mitral valve E peak/A peak (E/A), pulmonary venous reflux velocity (PVAR), E peak linear velocity time (DT)] of patients in the three groups were compared to analyze the relationship between carotid ultrasound parameters and left ventricular diastolic function. 【Results】 The β, AC, EP, PEVβ, IMT, E/Em, E/A, DT, E/Vp and PVAR values of group A were higher than those of group B and C (P<0.05), while the above parameter values of group B were higher than those of group C (P<0.05).The correlation test results showed that there was a positive correlation between the carotid ultrasound parameters and the levels of left ventricular diastolic function in patients with coronary heart disease (P<0.05). 【Conclusion】 The carotid ultrasound parameters of patients with coronary heart disease are correlated with left ventricular diastolic function. The higher the carotid ultrasound parameters, the worse the left ventricular diastolic function. Clinically, the changes of left ventricular diastolic function in patients with coronary heart disease can be predicted based on the changes of various parameters of the carotid artery, which may be of positive significance for guiding early left ventricular diastolic function evaluation and formulation of treatment plan.
