Treatment of Right Heart Failure

Initial Assessment and Management

The European Society of Cardiology recommends monitoring heart rate, rhythm, blood pressure, and oxygen saturation continuously for at least the first 24 hours of admission 1
Maintaining oxygen saturation above 90% at all times is recommended 2

The European Heart Society suggests that diuretics are essential for symptomatic treatment when fluid overload is present (pulmonary congestion or peripheral edema) 3, 4
Loop diuretics (e.g., furosemide) are first-line therapy for managing fluid retention, according to the European Heart Journal 1
Consider doubling the dose of loop diuretic up to equivalent of furosemide 500 mg if no initial response, as recommended by the European Heart Journal 1
The American College of Cardiology recommends ACE inhibitors as first-line therapy in patients with reduced left ventricular systolic function who also have right heart failure 3

Dobutamine at 2.5-5.0 μg/kg/min can improve right ventricular output, according to the American Journal of Obstetrics and Gynecology 5
Consider milrinone (0.25-0.75 μg/kg/min) as an alternative inotrope, particularly for its additional pulmonary vasodilatory effects, but monitor for hypotension, as recommended by the American Journal of Obstetrics and Gynecology 5

Sildenafil (20 mg three times daily) may be considered for right heart failure associated with pulmonary hypertension, according to the American Journal of Obstetrics and Gynecology 5
Inhaled nitric oxide (5-40 ppm) may be considered for right heart failure associated with pulmonary hypertension, according to the American Journal of Obstetrics and Gynecology 5

Consider intra-aortic balloon pump or other mechanical circulatory support in patients without contraindications, as recommended by the European Heart Journal 1

Pulmonary artery catheterization should be considered in patients who are refractory to pharmacological treatment, persistently hypotensive, or have uncertain left ventricular filling pressure, according to the European Heart Journal 1

In right ventricular infarction, volume loading with normal saline (500-ml bolus, followed by 500 ml/h) is recommended unless there are signs of left heart volume overload, according to the Journal of the American College of Cardiology 6
Avoid excessive fluid administration in patients with a massively dilated right ventricle as this may increase right ventricular distention and compromise left ventricular filling, as recommended by the American Journal of Obstetrics and Gynecology 5

Before discharge, ensure the acute episode of heart failure has resolved, congestion is absent, and a stable oral diuretic regimen has been established for at least 48 hours, according to the European Heart Journal 1
Optimize long-term disease-modifying therapy and provide appropriate patient education, as recommended by the European Heart Journal and the European Journal of Heart Failure 1, 3

Right heart failure requires a fundamentally different approach than left heart failure, with cautious use of diuretics and vasodilators to avoid compromising right ventricular filling, while addressing the underlying cause—particularly pulmonary hypertension or acute coronary syndrome, as recommended by the European Society of Cardiology 7
Identify the underlying etiology immediately, as management differs dramatically based on cause, according to the European Heart Journal 7
Progressive isolated RV failure should be suspected to be caused by pulmonary hypertension, as stated in the European Heart Journal 7

Pulmonary vasodilators are the cornerstone of treatment for pulmonary hypertension-related RV failure, including type V phosphodiesterase inhibitors, endothelin antagonists, and prostacyclin analogues, as recommended by the European Heart Journal 7
Urgent coronary angiography and revascularization are recommended for acute coronary syndrome with RV involvement, as stated in the European Heart Journal 7
Diuretics and vasodilators should be used cautiously or avoided in isolated RV failure to prevent reducing RV filling pressure, as warned by the European Heart Journal 7
Certain medications such as NSAIDs, COX-2 inhibitors, class I antiarrhythmic agents, calcium antagonists, tricyclic antidepressants, and corticosteroids should be avoided or used with extreme caution, as advised by the European Heart Journal 8, 9

Before discharge, ensure the acute episode has resolved completely, congestion is absent, a stable oral diuretic regimen has been established, long-term disease-modifying therapy is optimized, and appropriate patient and family education has been provided, as recommended by the European Heart Journal 7
Monitor renal function, electrolytes, potassium, and sodium daily during IV therapy and when adjusting renin-angiotensin-aldosterone system antagonists, as suggested by the European Heart Journal 7
