EF and fs normal values of cardiac color Doppler ultrasound

EF refers to ejection fraction, which is normally between 50% and 75%. FS refers to ventricular short-axis contractility, which is normally between 25% and 45%.

Ejection fraction can reflect the pumping capacity of the heart. If ejection fraction is less than 50%, it is considered to be caused by excessive cardiac pressure load, primary myocardial damage, etc., which is related to coronary atherosclerotic heart disease, myocarditis, acute myocardial infarction, pulmonary hypertension, heart failure and other factors. Ventricular short-axis contractility can reflect left ventricular function. If ventricular short-axis contractility is less than 25%, it indicates impaired left ventricular systolic function.

Patients need to maintain a stable mood, pay more attention to the examination results, and decide the treatment plan according to medical advice.
