Key result
Exercise-induced E/Ea ratio >13 predicts elevated LVFP to reveal latent diastolic heart failure.
Why the study?
Does exercise echocardiography accurately diagnose latent diastolic heart failure by predicting increased left ventricular filling pressure?
Does exercise echocardiography accurately diagnose latent diastolic heart failure by predicting increased left ventricular filling pressure?
Exercise echocardiography using the E/Ea ratio shows promise for diagnosing latent diastolic heart failure, but requires further validation due to small and inconsistent studies.
May support latent diastolic heart failure diagnosis; leaves open routine use pending prospective validation.

Jaroslav Meluzı́n (2010) conducted a review in Heart failure with preserved left ventricular ejection fraction (primary diastolic heart failure). Exercise echocardiography was evaluated. Exercise echocardiography reveals latent diastolic heart failure, as an exercise-induced E/Ea ratio > 13 predicts elevated left ventricular filling pressure with 73% sensitivity and 96% specificity.
