Does left atrial reservoir strain improve diagnostic accuracy beyond conventional echocardiographic measures in discriminating HFpEF from non-cardiac dyspnea?
Left atrial reservoir strain is a promising echocardiographic marker for differentiating HFpEF from non-cardiac dyspnea, though further validation is needed.
Left atrial reservoir strain may provide enhanced diagnostic accuracy beyond conventional echocardiographic measures to discriminate HFpEF from NCD. Further study is required to verify the diagnostic utility of LA strain.
Reddy et al. (2019) studied this question.
