Heart failure is known as heart failure, and advanced heart failure may lead to wasting. Usually, heart failure is caused by aortic stenosis, hypertension, pulmonary hypertension, heart valve closure insufficiency and other factors, resulting in the structure or function of the heart is abnormal, so that the ventricular filling and ejection function is impaired, cardiac blood output is not able to meet the most basic metabolic needs of the body tissues. Heart failure can cause discomfort such as pulmonary and circulatory stasis. If heart failure is not treated as soon as possible, gastrointestinal and hepatic stasis may occur as the disease progresses, causing abdominal distension, loss of appetite, nausea, vomiting, etc., resulting in too little food intake, which does not replenish the nutrients required by the body, and may lead to emaciation. When it is clear that heart failure, it is necessary to reduce sodium intake in daily life, and if necessary, you can follow the doctor’s instructions to choose hydrochlorothiazide, elapril, metoprolol and other drugs, which can inhibit vasoconstriction, improve myocardial remodeling and prognosis, and effectively reduce the symptoms. If symptoms of heart failure appear or cause complications such as wasting, you should go to the hospital in time to avoid delaying the condition. The above drugs need to be used in a standardized manner under the guidance of a doctor.
