Choque cardiogênico e suas repercussões no metabolismo energético em cães.

Abstract

The cardiogenic shock is a syndrome caused by cardiac disorders whose main characteristics are deficit in cardiac output and systemic tissue hypoperfusion and results from systolic or diastolic dysfunction, valve involvement, decreased heart filling or severe arrhythmia. It can be diagnosed clinically by means of signs of hypoperfusion, hypotension and pulmonary congestion, the latter being characteristic of this shock modality. Radiographic, electrocardiographic, echocardiographic and biochemical tests also help in the diagnosis. Metabolically, cardiogenic shock causes scarcity of oxygen, which causes numerous biochemical changes in the animal, mainly the exacerbated lactate production, resulting in acidosis. The treatment of this syndrome is directed at the underlying disease, and rapid therapeutic intervention and hemodynamic monitoring are extremely important for success. This study aimed to explain the main aspects of cardiogenic shock and its clinical andmetabolic changes, through a literature review.
