Echocardiography was carried out to determine function of the left ventricle (LV) by an ultrasound-based noninvasive technique (Transthoracic Echocardiography, Visual Sonics Vevo 770 with RMV 710B probe, Toronto, Canada). Animals were anesthetized with 2% isoflurane (Forane; Abbott Laboratories, Queenborough, UK) mixed with room air. Prior to starting the treatment protocol, echocardiography measurements were performed at baseline and then 4 days before and 7 wks after myocardial infarction (MI) or sham operation in anesthetized rats (Figure 1B ). Diastolic and systolic dimensions of left ventricle (LV) were measured during echocardiography evaluation including anterior and posterior wall thickness (AWTd, PWTd, AWTs, PWTs) and LV cavity diameter (LVDd, LVDs). From these dimensions, the following functional echocardiography parameters were derived: fractional shortening (FS) using the formula (LVDd-LVDs)/LVDd*100, systolic thickening of anterior wall (ΔAWT) from the equation (AWTs-AWTd)/AWTd* 100, and relative wall thickness from the equation (AWTd-PWTd)/LVDd*100.

The RMV 710B is a high-frequency ultrasound probe for small animal imaging. It is designed to capture detailed images of anatomical structures in small laboratory animals. The probe operates at a frequency of 40 MHz, enabling high-resolution imaging. Its core function is to provide researchers with a tool for non-invasive visualization and analysis of small animal models.

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.
