Management of Multivessel Disease and Cardiogenic Shock.

Cardiogenic shock represents a state of low cardiac output and systemic hypoperfusion resulting in insufficient end-organ perfusion and consequent multiorgan failure. The main cause of this complication in the context of acute ST-elevation myocardial infarction is left ventricular dysfunction secondary to poor myocardial perfusion. In over 50% of cardiogenic shock cases, there is evidence of significant coronary stenosis within noninfarct-related arteries. Persistent ischemia in the noninfarct territory may contribute to ongoing hypotension. Currently, ESC and ACC/AHA/SCAI guidelines advocate complete revascularization in the context of multivessel coronary artery disease in the context of cardiogenic shock, although the evidence is weak.
