Clinical signs suggestive of tissue hypoperfusion are [133, 134, 160]: • tachycardia, • hypotension (sBP < 90 mm Hg, MAP < 70 (60) mm Hg, or BP-drop > 40 mm Hg), • oligo-/anuria, • clinical or biological signs of extracellular ﬂuid depletion (ketoacidosis, vomiting, diarrhoea), • delayed capillary reﬁll, • mottled skin, • altered level of consciousness. Menon  strongly recommends a diagnosis of cardiogenic shock (CS) in all patients exhibiting signs of inadequate tissue perfusion in the setting of severe cardiac dysfunction irrespective of the BP.
11]). SV depends decisively on the magnitude of the afterload [3, 51, 102]. Furthermore, an elevated (after) load causes an increase in the LV ﬁlling pressure, producing high LVEDP  and thus aﬀecting the already compromised diastolic properties of the heart, resulting in a further reduction of the LV ﬁlling rate [405, 406]. Afterload is inversely proportional to the stroke volume, SV ^ 1/afterload  and therefore an increase in afterload should result in a fall in SV and ejection fraction (EF) [370, 407].
Kelly established proof that Ea and its changes correlate very well with varying loading and inotropic conditions, reﬂecting relative eﬀects of vasodilation on cardiac performance adequately and, so, predicting eﬀects and beneﬁts of therapy . 5 Afterload c) Afterload in acute heart failure syndromes The fundamental pathophysiological alteration in acute heart failure syndromes is a substantially and inappropriately elevated afterload with a markedly elevated systemic resistance / markedly increased LV outﬂow impedance exerting a high (end-)systolic load on the LV during ventricular ejection [11, 20, 402].
