Echocardiography was performed by an experienced sonographer who had received advanced training and certification in echocardiographic imaging, according to the guidelines of the American Society of Echocardiography (ASE). M-mode echocardiography was used to measure LA dimensions, and the LVEF was calculated with Simpson’s method. Doppler echocardiography assessed early (E) and late (A) diastolic mitral inflow velocities and the E/A ratio.30 (link),31 (link)

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
