The EIDOS and DoTS descriptions of takotsubo cardiomyopathy due to catecholamines are shown in Figure 1. 

Actions of angiotensin are mimetic of the motor actions of either acetylcholine or catecholamines. As discussed below, such actions are due to a direct effect of the peptide on the effector organ or to an indirect action through stimulation of the motor nerves or liberation of chemical transmitters at nerve endings. A brief description of these actions shall be given here.
