Cardiogenic Shock: Recent Developments and Significant Knowledge Gaps.

ABSTRACT

PURPOSE OF REVIEW Patients with cardiogenic shock (CS) continue to have high rates of morbidity and mortality. We aimed to describe current principles in the management of CS including coronary revascularization, medical management, mechanical circulatory support, and supportive care. RECENT FINDINGS: Revascularization is still recommended, but trials have not found a benefit in the revascularization of nonculprit artery lesions. New mechanical circulatory support options are available, but optimal use remains uncertain. Overall improvement in outcomes appears to have plateaued. There remain substantial knowledge gaps about the management of CS. The ideal timing and selection criteria for mechanical support remain under-developed. There has been little systematic study to inform medical management or supportive care of this patient population. A more expansive research focus is necessary to improve the care of CS.
