“Objective: We investigated the feasibility
of continuous detection of myocardial ischemia during cardiac surgery with a 3-axis accelerometer.
Methods: Ten patients with significant left anterior descending coronary artery stenosis underwent off-pump coronary artery bypass grafting. A 3-axis accelerometer (11 X 14 X 5 mm) was sutured onto the left anterior descending coronary artery-perfused region of left ventricle. Twenty episodes of ischemia were studied, with 3-minute occlusion of left anterior descending coronary artery at start of surgery and 3-minute occlusion of left internal thoracic artery at end of surgery. Longitudinal, circumferential, and radial accelerations were continuously measured, with epicardial velocities calculated from the signals. During occlusion, accelerometer velocities were compared with anterior left
ventricular longitudinal, circumferential, and radial strains obtained by echocardiography. Ischemia was defined by change in strain greater than 30%.
Results: Ischemia was observed echocardiographically during 7 of 10 left anterior descending coronary artery occlusions
but not during left internal thoracic artery occlusion. During ischemia, there were no significant electrocardiographic ARS-1620 or hemodynamic changes, whereas large and significant changes in accelerometer circumferential peak systolic (P < .01) and isovolumic (P < .01) velocities were observed. During 13 occlusions, no ischemia was demonstrated by strain, nor was any change demonstrated by the accelerometer. A strong correlation was found between circumferential Pexidartinib cell line strain and accelerometer circumferential peak systolic velocity during occlusion (r = 0.76, P < .001).
Conclusions: The epicardial accelerometer detects myocardial ischemia with great accuracy. This novel technique has potential to improve monitoring of myocardial ischemia during cardiac surgery.”
“Testosterone modulates mood and sexual function in women. However, androgen levels decline with age, which may relate to the age-associated change in sexual functioning and the prevalence of mood and anxiety disorders. These effects of testosterone are potentially mediated by the amygdala. In the present study, we investigated whether the age-related decline in androgen levels is associated with reduced amygdala activity, and whether exogenous testosterone can restore amygdala activity.
