Key result
Echocardiographic evaluation should extend beyond simple ejection fraction to include parameters like left ventricular filling pressure, left atrial volume, and global longitudinal strain to better detect subclinical myocardial dysfunction.
Why the study?
Although left ventricular ejection fraction is the most frequently used parameter for clinical decision-making, echocardiography offers additional invaluable parameters that should be evaluated in patients suspected of having myocardial disease.
Highlights the importance of evaluating echocardiographic parameters beyond just left ventricular ejection fraction in patients with suspected myocardial disease.
Left ventricular ejection fraction (LVEF) is the most frequently used echocardiographic parameter. LVEF based heart failure classification, timely intervention in a patient with valvular disease (e.g. aortic stenosis, mitral regurgitation), deterioration of myocardial function in a patient treated with chemotherapy; all need a simple LVEF value for decision-making process. An echocardiographic examination also contains several parameters with invaluable importance. Measurement and evaluation of these parameters should be made in every patient suspected of having myocardial disease.

Baysan et al. (2019) conducted a review in Myocardial disease. Advanced echocardiographic parameters (LV-GLS, LAVi, E/e') vs. Left ventricular ejection fraction (LVEF) alone was evaluated. Echocardiographic evaluation should extend beyond simple ejection fraction to include parameters like left ventricular filling pressure, left atrial volume, and global longitudinal strain to better detect subclinical myocardial dysfunction.
