Differential Diagnosis of Cardiac Structure,Blood Flow Velocity,and Fluctuation Velocity Status of Chronic Heart Failure with Cardiac Ultrasound
Objective To explore and analyze differential diagnostic effect of cardiac color Doppler ultrasound on cardiac structure,blood flow velocity,and fluctuation velocity of patients with chronic heart failure.Methods The paper reviewed and analyzed clinical diagnosis and treatment data of 90 patients with chronic heart failure(observation group)in our hospital from January 2022 to June 2023,and divided them into normal group(n=23 cases)and decreased group(n=67 cases)according to left ventricular ejection fraction;chose patients with physical examination during the same period as control group(n=90 cases),Clinical differential diagnosis effect was explored based on cardiac ultrasound.Results Observation group(chronic heart failure patients)had lower LVEF,but higher LVEDD and LAD than control group(healthy examinees),(P<0.05).Expression level of LVEF in normal group was lower than decreased group,expression levels of LVEDD and LAD were higher than control group(P<0.05).Expression level of LVEF in grade Ⅲ and Ⅳ patients was lower than grade I and Ⅱ patients(P<0.05).Conclusion Cardiac ultrasound can reflect heart tissue,blood flow velocity,and fluctuation velocity of patients with chronic heart failure clearly and intuitively,can provide some certain reference basis for clinical physicians to distinguish diseases and develop personalized diagnosis and treatment methods.
