ReviewThe changing face of cardiogenic shock: definitions, epidemiology, and severity assessment.
Cardiogenic shock (CS) has been recognized for >50 years, most commonly in the setting of myocardial infarction. This review covers recent advances in the definitions, epidemiology and severity assessment of cardiogenic shock. ⋯ Cardiogenic shock mortality has not changed in a significant way in many years. Recent advances such as more granular assessment of shock severity have the potential to improve outcomes by allowing research to separate the patient groups which may respond differently to various therapies.

ReviewIs there a role for ketones as alternative fuel in critical illness?
The evidence base advocating ketones as an alternative substrate for critically ill patients is expanding. We discuss the rationale for investigating alternatives to the traditional metabolic substrates (glucose, fatty acids and amino acids), consider evidence relating to ketone-based nutrition in a variety of contexts, and suggest the necessary future steps. ⋯ Whilst ketones provide an attractive nutritional option, further research is required to determine whether the proposed benefits are translatable to critically unwell patients.

There is emerging evidence on the role of the multimodality imaging in the setting of cardiogenic shock. The utility of different imaging modalities, along with their pitfalls and limitations, and their integration in a multiparametric approach are discussed in the current review. ⋯ Although validation of the integrated approaches and single parameters are needed, the physiopathological-driven approach using ultrasound in patients with cardiogenic shock on top of the clinical and biochemical evaluation, may aid to a quicker and more detailed evaluation of patient's phenotype.
