Cardiogenic edema can be relieved by general treatment, drug treatment, etc. General treatment includes low-salt diet, etc. Drug treatment includes the use of furosemide and other diuretics under the guidance of a doctor to treat foot edema. 1. Congestive heart failure: coronary heart disease, hypertension, rheumatic heart valve disease and other heart diseases can lead to increased cardiac preload, congestive heart failure, resulting in circulation stagnation, foot edema. Daily life need to pay attention to low-salt diet, reduce sodium retention, at the same time can be used under the guidance of the doctor furosemide, hydrochlorothiazide and other diuretics to improve the symptoms of foot edema. 2. Pulmonary heart disease: due to long-term pulmonary hypertension, the heart afterload increases, which in turn causes myocardial contractility to weaken, the heart pumping dysfunction, ultimately leading to right heart failure, blood clots in the circulation, edema in the feet. In daily life, we need to pay attention to low-salt diet to reduce sodium retention, and at the same time, we can use furosemide and other diuretics under the guidance of the doctor to improve the symptoms of foot edema.
