What are the differences in treatment between left heart failure and right heart failure?

The differences in treatment between left-sided heart failure and right-sided heart failure include variations in treatment goals, treatment priorities, and specific therapeutic measures.

1. Treatment goals: The goal of treating left-sided heart failure is to prevent or reverse cardiac remodeling and improve symptoms and quality of life; the goal of treating right-sided heart failure is to enhance myocardial contractility and reduce both preload and afterload on the right ventricle.

2. Treatment priorities: The focus in managing left-sided heart failure lies in actively treating underlying diseases and eliminating precipitating factors, with common underlying conditions including hypertension, diabetes, and coronary artery disease. In contrast, the management of right-sided heart failure emphasizes aggressive treatment of primary diseases such as congenital heart disease and valvular heart disease.

3. Specific treatment measures: Specific interventions for left-sided heart failure include placing the patient in a sitting position to reduce cardiac workload, administering high-flow oxygen, rapid diuresis, and repeated use of morphine. For right-sided heart failure, specific measures involve actively managing the primary disease causing the condition, reducing myocardial load, enhancing myocardial contractile function, and preventing complications.
