Introduction
The main reason for using diuretics before cardiac stimulants in left heart failure is to relieve pulmonary compression and reduce the burden on the heart. Patients with heart failure often have impaired cardiac systolic and diastolic function, which can easily lead to pulmonary congestion, dyspnea, lower limb edema, and even generalized edema. Therefore, diuretic medications help increase urine output and eliminate excess fluid.
Left heart failure is treated with diuretics before using cardiac stimulants mainly because this approach helps relieve pulmonary compression and reduce the burden on the heart.
Patients with heart failure often have impaired cardiac systolic and diastolic functions, which can easily lead to pulmonary congestion, dyspnea, lower limb edema, and even generalized swelling. Therefore, using diuretic medications increases urine output, reduces venous return to the heart, and thereby decreases the cardiac load and improves symptoms of congestion in left heart failure, effectively reducing the heart's workload. Additionally, lowering fluid pressure on the lungs can improve the patient's breathing, and diuresis in left heart failure also reduces the total effective blood volume in the body.
During treatment, patients with left heart failure should ensure adequate rest and avoid excessive fatigue. They should keep their bodies warm and prevent upper respiratory tract infections, which could lead to pulmonary infection and hinder recovery. Patients are advised to maintain an optimistic and positive mindset, control their intake of fluids and sodium, and consume more fresh vegetables and fruits in daily life, all of which are beneficial for disease recovery.
