About

In 2016, the European Heart Association defined the median ejection fraction heart failure for the first time. More research is needed to improve our understanding of this population, so as to make the best clinical decision and improve the prognosis. In this study, 3D-STI was used to evaluate left ventricular systolic function in heart failure with median ejection fraction.

Full description

As the final manifestation of cardiovascular disease and the main cause of death, heart failure is one of the important challenges threatening human health in the 21st century. In 2016, the European Heart Association proposed a new classification standard for heart failure. In particular, for the first time, heart failure with median ejection fraction has been clearly defined. These patients have received more and more attention, but there are still relatively few studies on them. More research is needed to improve our understanding of this part of the population in order to make the best clinical decisions and improve the prognosis. 3D speckle tracking technology is a new technology developed on the basis of real-time three-dimensional echocardiography and speckle tracking technology. It is gradually recognized in the evaluation of left ventricular systolic and diastolic function, especially in the evaluation of cardiotoxicity of chemotherapy drugs. At present, the application of 3D-STI in the evaluation of left ventricular systolic function in heart failure with median ejection fraction is limited and needs further study.In this study, 3D-STI was used to evaluate left ventricular systolic function in heart failure with median ejection fraction.
