A cardiac ultrasound EF value of 75% is on the high side, which may be normal or due to certain diseases, and needs to be combined with relevant tests for further diagnosis.
The EF value of cardiac ultrasound represents the ejection fraction of the heart, which is the percentage of the blood injected into the blood vessels with each beat of the heart and the end-diastolic volume of the left ventricle, and is used to reflect the function of the heart.
The normal range for clinical reference is 50-70%; an EF value of less than 50% suggests cardiac insufficiency and reduced myocardial contractility. An EF greater than 70% suggests an increase in myocardial contractility, which can be physiologic or pathologic. For example, some athletes, after long-term training, cardiopulmonary function is higher than normal, in this case the EF value is high, may not need further treatment. However, some patients with hyperthyroidism or anemia may also have increased EF values, which need to be further diagnosed by perfecting the thyroid function, blood tests and other laboratory tests.
