Abstract Objective: To evaluate the left ventricular function and hemodynamic characteristics of patients with hypertensive heart disease based on echocardiography. Method: One hundred and ten patients with hypertensive heart disease who were treated in Taizhou Third People's Hospital from June 2019 to March 2022 were randomly selected as the study group. At the same time, one hundred and ten healthy people who underwent echocardiography examination in author's hospital during the same period were selected as the control group, and the echocardiography test results of the two groups of subjects were recorded. According to the examination results, the left atrial function related index parameters of the two groups of subjects include left atrial diamete (LAD), left atrial diameter index (LADI), left ventricular end systolic diameter (LVESD), left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), related parameters of hemodynamic characteristic indexes include cardiac output (CO), cardiac output index (CI), stroke volume (SV), stroke volume index (SVI), and related parameters of left ventricular function and hemodynamic characteristics in patients with different hypertension grades were compared and analyzed. Result: Compared with the control group, the index parameters of LAD, LADI, LVESD and LVEDD in the study group were significantly increased, and the index parameters of LVEF was significantly decreased (P<0.05). Compared with the control group, the index parameters of CO, CI, SV and SVI in the study group decreased significantly (P<0.05). The LAD, LADI, LVESD and LVEDD parameters of grade Ⅲ hypertension patients were significantly higher than those of grade Ⅰ and Ⅱ, and the LVEF parameters were significantly lower than those of grade Ⅰ and Ⅱ (P<0.05). The LAD, LADI, LVESD and LVEDD parameters of grade Ⅱ hypertension patients were significantly higher than those of grade Ⅰ, and the LVEF parameters was significantly lower than those of grade Ⅰ (P<0.05). The parameters of CO, CI, SV and SVI in patients with grade Ⅲ hypertension were significantly lower than those of grade Ⅰ and Ⅱ, with statistical significances (P<0.05). The parameters of CO, CI, SV and SVI in patients with grade Ⅱ hypertension were significantly lower than those of grade Ⅰ, with statistical significances (P<0.05). Conclusion: Echocardiography can effectively evaluate the left ventricular function and hemodynamics of patients, and has certain clinical application value.
