Cardiac insufficiency in pregnancy is manifested by pulmonary abandonment, acute pulmonary edema, and right heart failure. Heart disease during pregnancy can be divided into two main categories. The first category is pre-existing heart disease, mostly rheumatic and congenital heart disease, while hypertensive heart disease, mitral valve prolapse and hypertrophic heart disease are rare. The second category is pregnancy-induced heart disease, such as hyperemesis gravidarum and perinatal heart disease. So what are the screening tests for pulmonary abandonment of blood? Here is a brief introduction. Routine tests for pulmonary abandonment include: Doppler echocardiography, electrocardiogram, cardiovascular angiography (ERNA), etc. 1.Routine for ECG: Cardiac function monitoring includes clinical observation, auxiliary examinations such as ambulatory blood pressure monitoring, electrocardiogram, etc., as well as the detection of relevant blood biochemical indicators. 2.Echocardiography: A group of non-invasive examination methods that apply ultrasonic echo to probe the heart and large blood vessels to obtain relevant information. It includes M-type ultrasound, two-dimensional ultrasound, pulsed Doppler, continuous Doppler and color Doppler flow imaging, which helps to confirm the diagnosis of pulmonary hypertension and congenital heart disease categories. 3.X-ray: It should be used with caution for pregnant women. Images of pulmonary stasis, thickened pulmonary artery shadow, large right atrium and right ventricle may be seen. A good prognosis for pulmonary abandonment depends on effective cardiac volume, the presence of other complications that cause further cardiac burden, and the effectiveness of drug therapy. The prognosis is different if detected early, managed promptly, and monitored appropriately. Therefore, patients are advised to go to a regular hospital for systematic examination and treatment as soon as suspected symptoms are detected to avoid delays.
