Overview
Diagnostic Evaluation
- In clinical trials, particularly the SHOCK trial, cardiogenic shock in patients with acute myocardial infarction has been defined as:[1]
- Presence of ST-segment elevation, Q-wave infarction , new left bundle branch block, or posterior infarction with anterior ST-segment depression, complicated by shock due predominantly to left ventricular dysfunction.
- Hypotension (a systolic blood pressure of <90 mm Hg for at least 30 minutes or the need for supportive measures to maintain a systolic blood pressure of ≥90 mm Hg)
- End-organ hypoperfusion (cool extremities or a urine output of <30 ml per hour, and a heart rate of ≥60 beats per minute)
- Cardiac index of no more than 2.2 liters per minute per square meter of body-surface area
- Pulmonary-capillary wedge pressure of at least 15 mm Hg
Diagnostic Criteria
- Sustained hypotension (SBP <90 mm Hg or MAP 30 mm Hg below baseline in preexisting hypertension for at least 30 minutes)
- Evidence of tissue hypoperfusion (such as oliguria, cyanosis, cool extremities, and altered mental status)
- Presence of myocardial dysfunction after exclusion or correction of non-myocardial factors contributing to tissue hypoperfusion (such as hypovolemia, hypoxia, and acidosis)
- Sustained hypotension (SBP <90 mm Hg or MAP 30 mm Hg below baseline in preexisting hypertension for at least 30 minutes)
- Depressed cardiac index (<1.8 L/min/m2 of BSA without support or <2.0–2.2 L/min/m2 of BSA with support) in the presence of an elevated wedge pressure (>15 mm Hg).
