Gaubert M, et al. - Authors gauged if adenosine A2A receptors lead to vasodilation and positive inotropic function under stimulation and whether they play a role in controlling blood pressure in patients with cardiogenic shock. In patients with cardiogenic shock, they noted high adenosine plasma level and low A_2A receptor expression at admission vs acute heart failure or acute myocardial infarction. Findings suggested a probable contribution of this in the physiopathology of cardiogenic shock.
