Why the study?
Does measurement of left atrial compliance during exercise improve the diagnosis of HFpEF compared to exercise E/e' ratio or resting LA compliance in patients with dyspnoea?
Does measurement of left atrial compliance during exercise improve the diagnosis of HFpEF compared to exercise E/e' ratio or resting LA compliance in patients with dyspnoea?
Measuring left atrial compliance during exercise may improve the diagnostic accuracy for HFpEF in patients presenting with dyspnea compared to traditional resting measures or exercise E/e'.
Exercise LA compliance may aid HFpEF diagnosis in dyspnoea; hypothesis-generating and requires prospective validation before practice change.
Left atrial compliance during exercise demonstrated superior diagnostic ability to exercise E/e' ratio, with incremental diagnostic value over the resting LA compliance. Exercise LA compliance may enhance the diagnosis of HFpEF among patients with dyspnoea.
