Organ dysfunction is a key feature of cardiogenic shock. Active revascularization and contemporary management in intensive care has improved prognosis in cardiogenic shock, but mortality is still unacceptably high. This review will discuss the prevalence, manifestation, management and clinical impact of kidney and liver dysfunction in cardiogenic shock. ⋯ Monitoring renal and hepatic function and identifying injury and dysfunction of these organs is essential for the management and mortality risk assessment of patients in cardiogenic shock.

ReviewBone metabolism and fracture risk during and after critical illness.
There is growing evidence that bone health is impacted during and after critical illness in multiple ways. In this review, we provide a practical update on postcritical care bone loss with an insight on identification of persons at risk, prevention and treatment strategies. ⋯ A history of critical illness should be considered as a strong risk factor for osteopenia and osteoporosis. ICU-related bone loss should be part of the postintensive care syndrome, and should be targeted by prevention and treatment strategies. Optimized and individualized protein and micronutrient provision (with specific attention to calcium, vitamin D and selenium), associated with physiotherapy and muscle training, should be implemented early after ICU admission and continued after ICU discharge. Antiresorptive agents such as biphosphonates should be considered on an individualized basis.

ReviewThe best recipe: fat-based, protein-based, single amino acids?
Instead of comparing iso versus low energy or high versus low protein intake, the proportions between nutrients and the effects of specific amino or fatty acids may yield promising benefits for the nutritional therapy of critically ill patients. ⋯ The nutritional therapy should take into account the fact that lipids are more oxidized. Intravenous lipid emulsions containing olive and fish oil are preferred, improving morbidity significantly in a recent meta-analysis. Enteral protein should be selected carefully according to protein source, origin and amount. Hydrolyzed whey protein improves nitrogen balance. The ultimate goal is to preserve muscle mass and muscle function. β-Hydroxy-β-methylbutyrate may improve muscle strength.

Cardiogenic shock is a multifactorial and diverse entity in which inotropes are the cornerstone therapy. Although published clinical trials have focused on pharmacologic treatment of cardiogenic shock, there is lack of an established and widely accepted decision-making algorithm on the use of inotropic agents in cardiogenic shock. ⋯ Finally, proposes an algorithm of inotropes and vasopressors use and their potential combinations based on the clinical stage of cardiogenic shock. This algorithm can be used as a guide during the initial management of cardiogenic shock while underlying cause investigation is underway.

Cardiogenic shock is a severe complication with mortality rates of ∼50% that requires a rapid and complex management to aid and identify the highest and lowest risk patients. To that end, novel cardiogenic shock biomarkers are needed to improve risk stratification and to personalize therapy. ⋯ A new wave of research focused on novel proteomic and molecular techniques, is providing new candidates that promise to aid clinical decision-making and patient stratification in cardiogenic shock. The CS4P score is emerging as the most robust, yet it requires prospective validation in cardiogenic shock patients managed with circulatory and ventricular assist devices.
