Key result
Pulmonary system abnormalities directly drive exercise intolerance in chronic heart failure.
Why the study?
To propose that pulmonary system abnormalities contribute significantly to exertional dyspnea and exercise intolerance in patients with chronic heart failure.
Understanding the pulmonary mechanisms of exercise intolerance in heart failure highlights potential therapeutic targets, such as inspiratory muscle training and reducing pulmonary congestion.
Pulmonary abnormalities merit consideration in HF dyspnea assessment; leaves open whether targeted interventions improve exercise capacity in trials.
We propose that abnormalities of the pulmonary system contribute significantly to the exertional dyspnea and exercise intolerance observed in patients with chronic heart failure. Interventions designed to address the deleterious pulmonary manifestations of heart failure may, therefore, yield promising improvements in exercise tolerance in this population.

Lalande et al. (2019) conducted a review in Chronic heart failure. Pulmonary system abnormalities was evaluated. Abnormalities of the pulmonary system, including bronchial engorgement, ventilatory inefficiency, and pulmonary hypertension, are central determinants of exercise intolerance in chronic heart failure.
