Criteria of Cardiogenic Shock

In this article, we will discuss the Criteria of Cardiogenic Shock. So, let’s get started.

Criteria of Cardiogenic Shock

1. Systolic BP <90 mmHg or >60 mmHg fall below baseline level.

2. Cardiac index <2.2 L/min/m2. It is calculated by cardiac output divided by body surface area. Normal cardiac index is 2.6-4.2 (L/min/m2).

3. Left ventricular filling pressure or pulmonary capillary wedge pressure >18 mmHg; and pulmonary edema is usually present.

Transthoracic echocardiography (TTE): It is a non-invasive technique, provides same information as PCWP and CVP. It also differentiate hypovolemic shock (LV filling pressure is low but contractility is preserved) from cardiogenic shock (LV filling pressure is high but contractility is low/decreases). These hemodynamic parameters with clinical evidence of peripheral circulatory failure (e.g. altered mental state, cold clammy skin and oliguria with urine output <20 ml/hr) constitute clinical syndrome of cardiogenic shock.
