From the Guidelines
The best treatment for cardiogenic shock is a multidisciplinary team-based approach that includes immediate identification and stabilization with inotropic support, typically guided by invasively obtained hemodynamic data, and early consideration of mechanical circulatory support (MCS) as a temporizing strategy to support end-organ perfusion and blood pressure. This approach is supported by the 2022 AHA/ACC/HFSA guideline for the management of heart failure, which emphasizes the importance of team-based management and the use of MCS as a bridge to decision or recovery 1. The choice of inotropic agent is guided by blood pressure, concurrent arrhythmias, and availability of drug, with no clear benefit of one agent over another in cardiogenic shock 1.
Some key considerations in the management of cardiogenic shock include:
- The use of short-term MCS, such as intra-aortic balloon pump or Impella devices, which can provide hemodynamic benefits but also carry risks of vascular, bleeding, and neurologic complications 1
- The importance of understanding a patient's wishes, overall prognosis and trajectory, and assessment of therapeutic risk before proceeding with invasive temporary MCS 1
- The need for early diagnostic workup, including ECG, echocardiography, and cardiac biomarkers, to identify the underlying cause of cardiogenic shock and guide treatment 1
- The importance of careful fluid status assessment and avoidance of excessive fluid administration in most cases 1
The use of a shock team has been associated with improved outcomes, including reduced 30-day all-cause mortality and in-hospital mortality 1. Therefore, a team-based approach that includes early consultation with cardiology and critical care specialists, as well as consideration of MCS and other supportive therapies, is essential for optimal management of cardiogenic shock.
From the FDA Drug Label
Vasopressin injection is indicated to increase blood pressure in adults with vasodilatory shock who remain hypotensive despite fluids and catecholamines. Post-cardiotomy shock: 0.03 to 0.1 units/minute Septic shock: 0.01 to 0.07 units/minute
The best treatment for cardiogenic shock is not directly stated in the provided drug labels. However, for post-cardiotomy shock, which may be related to cardiogenic shock, the recommended dose of vasopressin is 0.03 to 0.1 units/minute [2] [3].
- Key points: + Vasopressin is used to increase blood pressure in adults with vasodilatory shock. + The dose for post-cardiotomy shock is 0.03 to 0.1 units/minute. + Cardiogenic shock treatment is not explicitly mentioned in the labels.
- Main idea: Vasopressin may be used in certain shock cases, but its use in cardiogenic shock is not directly addressed.

Treatment Options for Cardiogenic Shock
The treatment of cardiogenic shock typically involves the use of vasopressors and inotropes to restore adequate tissue perfusion. The choice of agent and dosage depends on the individual patient's pathophysiology and response to treatment 4, 5, 6, 7.
Vasopressor Therapy
- Norepinephrine is generally considered the first-line vasopressor agent due to its minimal adverse effects and association with better outcomes 4, 5, 6, 7.
- Vasopressin may be used as an alternative in patients with tachycardia or pulmonary hypertension 5, 6.
- Epinephrine is associated with an increased risk of refractory shock and death, and its use is generally not recommended as a first-line agent 5, 6.
Inotrope Therapy
- Dobutamine is the first-line inotrope agent, and is used to increase cardiac output and improve tissue perfusion 4, 5, 7.
- Levosimendan is a calcium sensitizer agent that can be used as a second-line agent or in patients who have been previously treated with beta-blockers 5, 7.
- The use of inotropes should be individualized and based on the patient's hemodynamic response 5.
