Flashcards

High-output heart failure

Heart failure caused by conditions requiring increased cardiac output (CO), such as hyperthyroidism, infection, or anemia, when increased blood flow can't meet oxygen demand.

Acute heart failure

Sudden reduction in cardiac function, often triggered by events like a heart attack (myocardial infarction).

Chronic heart failure

Progressive worsening of heart function, often associated with conditions like cardiomyopathy, valve problems, or coronary artery disease.

Pulmonary edema (cardiogenic)

Fluid buildup in the lungs due to impaired left ventricle function, causing elevated pressure in the pulmonary blood vessels.
