The distinction between cardiogenic edema and nephrogenic edema is mainly made from the following aspects: 1. The nature of edema: cardiogenic edema is generally less mobile and more solid; nephrogenic edema is softer and more active; 4, concomitant symptoms: cardiogenic edema is often accompanied by signs of cardiac insufficiency, such as enlarged heart, heart murmur, hepatomegaly, and elevated venous pressure; nephrogenic edema is often accompanied by hypertension, proteinuria, hematuria, and tubular urine.
