Circulatory Failure Overview

Circulatory Failure

• Circulatory failure is caused by primary cardiac dysfunction, peripheral circulatory disorders, vascular tone disturbances, combined heart and blood vessel dysfunction, hypovolemia, and compensatory myocardial hypertrophy.
• Chronic circulatory failure (CCF) can be categorized into degrees (I, IIA, IIB, and III). Each degree presents different symptoms.
• Tachycardia and shortness of breath are common symptoms associated with circulatory failure.
• Heart failure is characterized by decreased myocardial contractility, decreased stroke volume, reduced cardiac output, and decreased residual systolic blood volume.
• Myocardial infarction, cardiosclerosis, acute myocarditis, acute decompensation of hypertrophied myocardium, and attacks of paroxysmal tachycardia are among the causes of acute heart failure.
• Arterial hypertension of the systemic circulation, and arterial hypertension of the pulmonary circulation, and infarction of the left ventricle are causes of right ventricular failure.

Right Ventricular Failure

• Right ventricular failure is often characterized by ascites, swelling of jugular veins, swelling of lower extremities, hepatomegaly, and pulmonary edema.

Cardiogenic Pulmonary Edema

• Cardiogenic pulmonary edema develops due to either right or left ventricular failure.
• Left ventricular failure can be caused by mitral valve insufficiency, infarction of the left ventricle, and pulmonary hypertension.
• The causes of left ventricular failure often include mitral valve insufficiency, anterior wall infarction of the left ventricle, and pulmonary artery hypertension.
