Here is a quick tip about stress echocardiography. During stress echocardiography, both left ventricular dilatation and decline in global systolic function are indicative for severe coronary artery disease. Both are less common to occur with dobutamine stress echo rather than exercise echocardiography. However, hypotension is also a marker of severe coronary artery disease that is more likely to occur during dobutamine stress echocardiography. his may be due to the vasodialtor effect of dobutamine or due to dynamic left ventricular outflow tract obstruction with increased contractility.
