Chest X-ray manifestations of cor pulmonale

The heart is the largest hematopoietic organ in the human body, and when some organs around the heart become pathological, it will also affect the health of the heart. Among them, cor pulmonale is a heart disease caused by pulmonary bronchitis, and most of the time cor pulmonale is quite serious, so patients with cor pulmonale must go to the hospital for a comprehensive examination in time. What are the chest X-ray manifestations of cor pulmonale?

Chest X-ray findings of cor pulmonale include:

1.X-ray examination. In addition to the characteristics of underlying lung and chest diseases and acute lung infection, there may also be signs of pulmonary hypertension, such as dilatation of the right lower pulmonary artery trunk, with a transverse diameter ≥15mm; the ratio of its transverse diameter to the transverse diameter of the trachea ≥1.07; obvious protrusion of the pulmonary artery segment or its height ≥3mm; and signs of right ventricular enlargement, all of which are the main basis for diagnosing cor pulmonale. .

2. Electrocardiogram examination. The main manifestations include changes in right ventricular hypertrophy, such as right axis deviation, average axis in the frontal plane ≥+90°, severe clockwise rotation, Rv1+Sv5≥1.05mV and pulmonary type P wave. Right bundle branch block and low voltage patterns may also be seen, which can be used as reference conditions for diagnosing cor pulmonale. In V1, V2, and even extending to V3, a QS wave resembling the pattern of a paroxysmal myocardial infarction may appear.

3. Echocardiography. Cor pulmonale is diagnosed by measuring the inner diameter of the right ventricular outflow tract (≥30mm), the inner diameter of the right ventricle (≥20mm), the thickness of the anterior wall of the right ventricle, the ratio of the inner diameters of the left and right ventricles (<2), the inner diameter of the right pulmonary artery or the enlargement of the pulmonary artery trunk and right atrium.

Due to chronic hypoxia and infection, patients with cor pulmonale have very low tolerance to digitalis drugs and are prone to digitalis poisoning, so digitalis drugs should be used with caution. The dosage of cardiotonic drugs should be small, and cardiotonic drugs with fast action and rapid excretion should be selected, such as scutellaria baicalensis K 0.125-0.25 mg, or scutellaria baicalensis C 0.2-0.4 mg, and used under the guidance of a doctor.

Therefore, the chest X-ray manifestations of cor pulmonale can be understood based on the above introduction, and patients can also consult a doctor and learn more with the doctor's introduction.
