Coronary heart disease (CHD) is a clinical multiple cardiovascular disease that is mainly caused by coronary artery atherosclerosis. The incidence of CHD has recently increased, creating an urgent social and public health problem.
To provide a basis for the evaluation of cardiac function and disease severity in patients with CHD.
To evaluate the value of ultrasonography in the evaluation of cardiac function and lesion degree in patients with CHD.
A total of 106 patients with CHD and 106 healthy individuals were selected for this study. All subjects were examined by ultrasound, and the mitral orifice’s early-to-late diastolic blood flow velocity ratio (E/A), left ventricular end-diastolic volume (LVDd) and left atrial diameter (LAD) were measured. Values were compared between the study group and healthy group, and the correlation between the ultrasonic parameters of patients with different cardiac function grades and the degree of CHD were assessed.
E/A of the study group was smaller than that of the control group (1.88±0.44), while LVDd and LAD were larger. E/A for patients with grade III disease was smaller and LVDd and LAD were larger than those in patients with grade II disease. Patients with grade IV disease had smaller E/A and larger LVDd than patients with grade II and III disease. E/A was negatively correlated with cardiac function classification and disease severity, while LVDd and LAD were positively correlated with cardiac function classification and disease severity.
The ultrasonic parameters of patients with CHD are significantly different in patients with different cardiac function grade, lesion degree and prognosis. They can be used to evaluate the disease’s condition and prognosis, providing an objective reference for disease diagnosis and treatment.
There is a close relationship between CHD and ultrasound parameters, which has a wider clinical application value.
