Acute on chronic systolic heart failure

Last edited: 4/10/2026

Overview

Acute on chronic systolic heart failure (ACSH) is a clinical syndrome characterized by a sudden worsening of symptoms in patients with pre-existing systolic heart failure. This exacerbation often leads to increased hospitalizations and mortality.

Diagnosis

  • Invasive hemodynamic testing, including right heart catheterization, is crucial for accurate diagnosis, phenotyping, and management of complex heart failure 1.
  • Hemodynamic assessment may include baseline and provocative testing (e.g., volume challenges, vasodilator challenges) to evaluate response to interventions and assess conditions like pulmonary hypertension 1.
  • Standardization of hemodynamic protocols is needed due to limited consensus on interpretation 1.
  • Management

  • Invasive hemodynamic testing can guide management strategies, including vasodilator challenges to assess pulmonary hypertension reversibility in heart failure 1.
  • Provocative hemodynamic studies, such as volume challenges, can inform management decisions 1.
  • Key Recommendations

  • Invasive hemodynamic testing, including right heart catheterization, is recommended for accurate diagnosis, phenotyping, and management of heart failure 1. (Evidence: Expert opinion)
  • Provocative hemodynamic studies, such as volume challenges and vasodilator challenges, should be considered to guide management decisions in heart failure 1. (Evidence: Expert opinion)
  • Standardization of invasive hemodynamic protocols and interpretation is necessary for consistent and effective patient care 1. (Evidence: Expert opinion)
