Introduction
Cardiac function refers to the heart's ability to pump blood. By performing an ultrasound scan of the heart, one can observe the heart's systolic and diastolic functions. Clinically, evaluations mainly include chest X-rays and pulmonary CT imaging, which allow assessment of the heart's size and轮廓 (contour) based on imaging results. Blood tests can measure levels of biomarkers such as B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP); a significant elevation in these indicators may be observed.
Cardiac function refers to the heart's performance, and its assessment methods include cardiac ultrasound, chest X-ray, blood tests, etc. Specific analyses are as follows:
1. Cardiac Ultrasound
Ultrasound is widely used in clinical practice. By performing an ultrasound scan of the heart, it allows observation of the heart's systolic and diastolic functions, serving as an important indicator for evaluating cardiac function.
2. Chest X-ray
Clinical evaluations mainly include chest radiography and pulmonary CT imaging. These help assess the size and outline of the heart, while also detecting conditions such as pulmonary congestion, edema, or pleural effusion.
3. Blood Tests
Blood tests can measure levels of biomarkers such as B-type natriuretic peptide (BNP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP). A significant increase in these markers indicates the presence of heart failure.
In addition, other tests such as radionuclide imaging and electrocardiography (ECG) may also be performed. If abnormal cardiac function is detected, appropriate treatment strategies should be selected based on the specific clinical situation.
