Abstract

Cardiogenic shock is characterized by a decrease in myocardial contractility, and presents a high mortality rate. Inotropic and vasopressor agents have been recommended and used for several years in the treatment of patients in shock, but they remain controversial. Despite its beneficial effect on myocardial contractility, the side effects of inotropic therapy (arrhythmias and increased myocardial oxygen consumption) may be associated with increased mortality. The pharmacodynamics of different inotropic agents suggest benefits in specific situations, but these differences have not been reflected in reduced mortality in most studies, making it difficult to formulate recommendations. This review integrates data from different studies on the use of inotropes and vasopressors in patients with cardiogenic shock, proposing a therapeutic scheme for the pharmacological treatment of patients in cardiogenic shock according to the patient's hemodynamic profile.

Keywords: Cardiogenic shock; Choque cardiogénico; Inotropes; Inotrópicos; Vasopressores; Vasopressors.
