Heart failure patients with swollen limbs can be treated by general treatment such as bed rest, application of diuretics such as furosemide, and treatment for primary diseases. 1. General treatment: absolute bed rest, reasonable rest, avoiding excessive activity to increase the burden on the heart, strictly limiting water intake, and reducing the intake of food with high water content. 2. Drug therapy: including renin angiotensin system inhibitors such as ACEI class captopril, ARB class of chlorosartan; β-blockers such as bisoprolol; aldosterone receptor antagonists such as spironolactone; and SGLT2i such as dagliflozin. Specific medications should be prescribed by the doctor. 3. Etiological treatment: When acute coronary syndrome causes severe myocardial ischemia and heart failure due to reduced ventricular systolic function, it is necessary to perform percutaneous coronary intervention in a timely manner by placing a coronary stent; when atrial fibrillation, supraventricular tachycardia, ventricular tachycardia and other arrhythmias lead to heart failure, it is necessary to comply with the doctor’s instructions to use anti-arrhythmic drugs such as lidocaine, amiodarone, propafenone, etc, or radiofrequency ablation and other forms of treatment. Heart failure patients should go to the hospital in time and follow the doctor’s instructions to avoid delays. Pay attention to the use of medication under the guidance of a physician.
