Recommended management strategies for a patient with pleural effusion caused by heart failure include:

  • Confirm diagnosis and assess cardiac function: Use ultrasonography to exclude or confirm pleural effusion and echocardiography to assess cardiac function and guide management .
  • Optimize heart failure treatment: Offer low to medium dose loop diuretics (e.g., furosemide less than 80 mg daily) to control sodium and water retention, relieve breathlessness, and reduce pleural effusion .
  • Titrate diuretics according to symptoms: Adjust the dose based on symptom control and review regularly; if symptoms persist despite maximal doses, seek specialist advice .
  • Review and stop drugs that may worsen heart failure: Ensure medications that exacerbate heart failure are discontinued where appropriate .
  • Consider additional heart failure therapies: Add ACE inhibitors and beta-blockers as tolerated to improve symptoms and prognosis; if ACE inhibitors are not tolerated, use angiotensin-II receptor antagonists .
  • Manage comorbidities and precipitating factors: Optimize treatment of any underlying causes or comorbid conditions contributing to heart failure and pleural effusion .
  • Monitor renal function and fluid status: During diuretic therapy, closely monitor renal function, weight, and urine output to avoid complications .
  • Provide follow-up and care planning: Arrange appropriate follow-up in primary care and ensure a care plan is in place including symptom monitoring and access to specialist heart failure services ,.
