Left-Sided Heart Failure vs Right-Sided Heart Failure Pathophysiology Nursing NCLEX Review
RegisteredNurseRN・2 minutes read
Left-sided and right-sided heart failure have distinct symptoms and causes, with right-sided failure leading to venous congestion and left-sided failure causing pulmonary congestion. Ejection fraction monitoring is vital for determining severity, highlighting the importance of recognizing and managing symptoms accordingly.
Insights
- Right-sided heart failure leads to venous congestion, causing symptoms like leg swelling, abdominal distention, and jugular vein distention.
- Left-sided heart failure results in pulmonary congestion, manifesting in breathing difficulties, increased heart rate, and nocturnal dyspnea. Monitoring ejection fraction is key to assessing heart failure severity accurately.

Recent questions
What are the differences between left and right-sided heart failure?
Left-sided heart failure causes congestion in pulmonary circulation due to the heart's inability to pump properly, while right-sided heart failure results in congestion in venous circulation. Left-sided heart failure can be categorized as systolic (reduced ejection fraction) or diastolic (preserved ejection fraction), impacting blood filling or contraction, respectively.
What are the signs of right-sided heart failure?
Signs of right-sided heart failure include swelling in legs, feet, and abdomen, weight gain, pitting edema, jugular venous distention, lethargy, irregular heartbeat, nausea, and increased abdominal girth. These symptoms are a result of congestion in venous circulation leading to various manifestations in the body.
How does left-sided heart failure affect the body?
Left-sided heart failure causes congestion in pulmonary circulation due to the heart's inability to pump properly. This can result in difficulty breathing, crackles in the lungs, orthopnea, weakness, nocturnal dyspnea, increased heart rate, nagging cough, and weight gain. These symptoms are indicative of the heart's inability to effectively pump blood to the rest of the body.
Why is monitoring ejection fraction important in heart failure?
Monitoring ejection fraction is crucial for understanding heart failure severity. Systolic dysfunction results in a low ejection fraction, impacting contraction, while diastolic dysfunction involves a stiff ventricle hindering normal blood filling. By monitoring ejection fraction, healthcare providers can assess the heart's ability to pump blood effectively and tailor treatment accordingly.
How can one effectively manage left and right-sided heart failure symptoms?
Understanding the distinctions between left and right-sided heart failure is essential for recognizing and managing the associated signs and symptoms effectively. Treatment may involve medications to improve heart function, lifestyle changes such as a low-sodium diet, regular exercise, and monitoring fluid intake. In severe cases, interventions like implantable devices or heart transplant may be necessary. Early detection and management are key in improving outcomes for individuals with heart failure.
