Refractory heart failure

Last edited: 4/23/2026

Overview

Refractory heart failure refers to heart failure that persists despite optimal medical therapy, often necessitating advanced support modalities like extracorporeal membrane oxygenation (ECMO) for temporary circulatory or respiratory assistance 12.

Diagnosis

  • Persistent symptoms despite guideline-directed medical therapy
  • Elevated natriuretic peptides (BNP/NT-proBNP)
  • Echocardiographic evidence of systolic or diastolic dysfunction
  • Clinical signs of fluid overload or hypoperfusion 1
  • Management

  • First-line treatments: Optimized medical therapy including ACE inhibitors, beta-blockers, diuretics, and aldosterone antagonists 1
  • Adjunctive therapies: In refractory cases, initiation of ECMO as a bridge to recovery, decision-making, transplant, or further diagnosis 12
  • Specific interventions: Venoarterial ECMO for circulatory support in refractory circulatory failure 2
  • Special Populations

  • Pediatrics: Increased use of ECMO in pediatric intensive care settings without robust randomized controlled trial evidence 1
  • Elderly: No specific details provided in abstracts regarding unique management considerations for elderly patients
  • Comorbidities: No specific guidance provided for managing refractory heart failure in the context of comorbidities 12
  • Key Recommendations

  • Consider ECMO as a supportive measure for patients with refractory cardiac failure to provide temporary circulatory support, serving as a bridge to recovery or other definitive treatments (Evidence: Moderate) 12
  • Evaluate neurological outcomes carefully in long-term survivors post-ECMO, as favorable outcomes are common in those who survive (Evidence: Moderate) 2
  • Implement suprainstitutional networks for remote ECMO support to enhance patient outcomes in refractory circulatory failure, leveraging multidisciplinary expertise (Evidence: Expert opinion) 2
