Key result
Left ventricular global longitudinal strain has emerged as a feasible instrument for early identification of subtle LV systolic dysfunction in valvular, cardiomyopathic, and COVID-19 diseases.
Why the study?
LV ejection fraction may not truly represent LV systolic function in certain cardiac diseases, prompting the need for myocardial strain to enable early identification of subtle dysfunction.
What are the emerging clinical applications of left ventricular global longitudinal strain in valvular and cardiomyopathic diseases and COVID-19?

Left ventricular global longitudinal strain is a feasible and robust instrument for the early identification of heart disease and subtle LV systolic dysfunction, potentially overcoming the limitations of LV ejection fraction.
There is an increasing prevalence of cardiovascular disease and heart failure. Indices of left ventricular (LV) systolic function such as LV ejection fraction used to identify those at risk of adverse cardiac events such as heart failure may not be truly representative of LV systolic function in certain cardiac diseases. Given that LV ejection fraction reduction may represent more advanced irreversible stages of disease, measures of myocardial strain have emerged as a feasible and robust instrument for the early identification of heart disease and subtle LV systolic dysfunction. The purpose of this review was to provide an overview of emerging clinical applications of LV global longitudinal strain in valvular and cardiomyopathic diseases and coronavirus disease 2019.
