Introduction
Cardiogenic edema generally causes pitting edema in the lower limbs, which is typically symmetrically distributed. The swelling usually appears or worsens in the afternoon and gradually diminishes or disappears after nighttime rest. Chest X-ray examination may reveal cardiac enlargement and pulmonary congestion. When accompanied by bacterial infection, blood tests may show a significant increase in white blood cell count.
Cardiogenic edema is usually caused by cardiac factors and can be diagnosed through clinical symptoms, chest X-ray, complete blood count, and other methods. The specific analysis is as follows:
1. Clinical Symptoms
Cardiogenic edema typically causes pitting edema in the lower limbs, which is characteristically symmetrically distributed. Symptoms often appear or worsen in the afternoon and gradually improve or resolve after nighttime rest. As the condition progresses, generalized edema may develop. Patients may also experience symptoms such as palpitations and coughing up pink frothy sputum.
2. Chest X-ray
Chest X-ray examination may reveal cardiac enlargement and pulmonary congestion. It also helps assess the size of the heart and the detailed condition of the lungs, providing important evidence for disease diagnosis.
3. Complete Blood Count (CBC)
If a bacterial infection is present, CBC results may show a significant increase in white blood cell count.
In addition, MRI can be used to evaluate the size, shape, and function of the ventricles. Specific diagnostic procedures should be carried out at a hospital under the guidance of a physician.
