Cardiogenic edema

Introduction Cardiac edema is caused by edema caused by cardiac dysfunction, heart disease caused by various causes, and edema occurs when heart failure occurs. The characteristics of cardiogenic edema are as follows: 1. The edema gradually forms. Firstly, the urine volume is reduced, the limbs are heavy, the body weight is increased, and then the lower limbs and systemic edema gradually appear. 2. Edema starts from the sagging part of the body and gradually develops into systemic edema. In general, the lower extremity can be depressed edema, which is most obvious. 3. Other symptoms and signs associated with right heart failure and elevated venous pressure, such as palpitations, asthma, jugular vein engorgement, hepatomegaly, and even chest and ascites.

Cause

Cause:

Acute muscle disease caused by genetic factors, characterized by progressive and atrophic edema of varying degrees and distribution of skeletal muscle, first manifested as decreased urine output, heavy limbs, weight gain, and then gradually appear lower extremities and systemic edema . Beginning with the sagging part of the body, it gradually develops into systemic edema with other symptoms and signs of right heart failure and elevated venous pressure, such as palpitations, asthma, jugular vein engorgement, hepatomegaly, and even chest and ascites.

Differential diagnosis

Classification of edema

According to their causes can be divided into the following categories:

(1) Cardiogenic edema: common in congestive heart failure, acute or chronic pericarditis.

(2) Nephrogenic edema: common in glomerulonephritis, pyelonephritis and nephrotic syndrome.

(3) Hepatogenic edema: common in viral hepatitis, cirrhosis and so on.

(4) dystrophic edema: common in hypoproteinemia, vitamin B1 deficiency and so on.

(5) Edema caused by connective tissue disease: common in lupus erythematosus, scleroderma and dermatomyositis.

(6) allergic edema: such as serum disease.

(7) Endocrine edema: common in Xi Han disease, hypothyroidism and Cushing's syndrome.

(8) idiopathic edema: such as functional edema.

(9) Others: anemia edema, toxic edema in pregnancy.
