Chronotropic incompetence across heart failure categories
Key result
Chronotropic incompetence links to worse HF prognosis, but beta-blocker withdrawal is discouraged in HFrEF.
Why the study?
Chronotropic incompetence in heart failure is associated with worse outcomes, but definitions vary, pharmacological therapies complicate its assessment, and management strategies remain debated.
What is the clinical impact of chronotropic incompetence in heart failure and what are the potential therapeutic strategies?

Implication
May support maintaining beta-blockers in HFrEF; leaves open optimal management of chronotropic incompetence.
Structured PICO
What is the clinical impact of chronotropic incompetence in heart failure and what are the potential therapeutic strategies?
P
Population
Patients with heart failure and chronotropic incompetence
E
Exposure
Pharmacological (e.g., beta-blockers) and non-pharmacological (e.g., rate-adapting pacing) therapeutic strategies
O
Outcome
Exercise capacity and prognosis
This review highlights that chronotropic incompetence in heart failure worsens prognosis and exercise capacity, but beta-blockers should still be maintained in HFrEF/HFmrEF.
Cite This Study
Magrì et al. (2024) conducted a review in Heart failure and chronotropic incompetence. Chronotropic incompetence was evaluated. Chronotropic incompetence in heart failure is associated with reduced exercise capacity and a worse prognosis, while beta-blocker withdrawal should be avoided in reduced ejection fraction.
