inotropic support
The use of medications to enhance cardiac contractility in patients with heart failure or cardiogenic shock.
Full Definition
Inotropic support refers to the therapeutic use of pharmacological agents that increase myocardial contractility to improve cardiac output in patients with acute or chronic heart failure. Common inotropic agents include dobutamine, milrinone, and dopamine, each with distinct mechanisms of action and hemodynamic profiles. These medications are typically reserved for hospitalized patients with severe systolic dysfunction or cardiogenic shock, as they may increase oxygen demand and arrhythmia risk. Duration and choice of agent depend on clinical scenario, renal function, and hemodynamic goals.
Usage
Usage note: Specify the agent used (e.g., 'dobutamine inotropic support') when possible.
