ABSTRACT

El shock cardiogénico (SC) es un síndrome heterogéneo con elevada mortalidad y creciente incidencia. Se trata de una situación en la que existe un desequilibrio entre las necesidades tisulares de oxígeno y la capacidad del sistema cardiovascular para satisfacerlas debido a una disfunción cardiaca aguda. Históricamente, los síndromes coronarios agudos han sido la causa principal de SC; sin embargo, los casos no isquémicos han aumentado en incidencia. Su fisiopatología implica el daño isquémico del miocardio, una respuesta tanto simpática como del sistema renina-angiotensina-aldosterona e inflamatoria, que perpetúan la situación de hipoperfusión tisular conduciendo finalmente a la disfunción multiorgánica. La caracterización de los pacientes con SC mediante una valoración triaxial y la universalización de la escala SCAI ha permitido una estandarización de la estratificación de la gravedad del SC que, sumada a la detección precoz y el enfoque Hub and Spoke, podrían contribuir a mejorar el pronóstico de los pacientes en SC.

Cardiogenic shock (CS) is a heterogeneous syndrome with high mortality and increasing incidence. It is a condition where there is an imbalance between tissue oxygen demands and the cardiovascular system's capacity to meet them due to acute cardiac dysfunction. Historically, acute coronary syndromes have been the primary cause of CS; however, non-ischemic cases have seen a rise in incidence. Its pathophysiology involves myocardial ischemic damage, a sympathetic, renin–angiotensin–aldosterone system, and inflammatory response, perpetuating the situation of tissue hypoperfusion, ultimately leading to multiorgan dysfunction. Characterizing CS patients through a triaxial assessment and the widespread use of the SCAI scale has allowed standardization of CS severity stratification, which, coupled with early detection and the “Hub and Spoke” approach, could contribute to improve the prognosis of CS patients.

ABSTRACT

Cardiogenic shock (CS) is a heterogeneous syndrome with high mortality and a growing incidence. It is characterized by an imbalance between the tissue oxygen demands and the capacity of the cardiovascular system to meet these demands, due to acute cardiac dysfunction. Historically, acute coronary syndromes have been the primary cause of CS. However, non-ischemic cases have seen a rise in incidence. The pathophysiology involves ischemic damage of the myocardium and a sympathetic, renin-angiotensin-aldosterone system and inflammatory response, perpetuating the situation of tissue hypoperfusion and ultimately leading to multiorgan dysfunction. The characterization of CS patients through a triaxial assessment and the widespread use of the Society for Cardiovascular Angiography and Interventions (SCAI) scale has allowed standardization of the severity stratification of CS; this, coupled with early detection and the "hub and spoke" approach, could contribute to improving the prognosis of these patients.

ABSTRACT

La complejidad de los procedimientos quirúrgicos, así como la comorbilidad de los pacientes sometidos a cirugía cardiaca, van en aumento. La detección y el tratamiento precoz de las complicaciones posquirúrgicas son parte del éxito en la reducción de la morbimortalidad. La introducción de la técnica ecográfica ha sido fundamental en la valoración cardiopulmonar, hemodinámica y etiológica del paciente crítico, aportando información inmediata, fiable y a veces concluyente, permitiendo aclarar muchas situaciones clínicas sin respuesta terapéutica aceptable, por lo que se trata de una herramienta diagnóstica esencial. En este capítulo nos centraremos, fundamentalmente, en la valoración funcional y hemodinámica, y en la detección de las complicaciones cardiológicas más frecuentes en el postoperatorio de cirugía cardiaca.

Surgical complexity as well as comorbidities in patients undergoing cardiac surgery is increasing. Early detection and management of post-surgical complications are key points to reduce morbidity and mortality. Ultrasound technique plays a main rol in cardiopulmonary, hemodynamic and etiological assessment of the critically ill, providing immediate, reliable and, sometimes, conclusive information, clarifying many clinical situations with an inappropriate therapeutic response. For all these reasons ultrasound is an essential diagnostic tool. In this chapter we will focus, mainly, on functional and hemodynamic assessment and on the detection of most common cardiological complications in the postoperative period after cardiac surgery.
