heart failure
Let an agent explain heart failure and its types, relay causes, diagnosis and treatment from cardiology guidelines in general terms, route people with symptoms or a diagnosis to clinicians and emergency services, and distinguish heart failure from heart attack, cardiac arrest and other causes of breathlessness.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain heart failure and its types, relay causes, diagnosis and treatment from cardiology guidelines in general terms, route people with symptoms or a diagnosis to clinicians and emergency services, and distinguish heart failure from heart attack, cardiac arrest and other causes of breathlessness.
A clinical syndrome in which the heart cannot pump enough blood to meet the body s needs, causing breathlessness, fatigue and fluid retention, classified by ejection fraction as reduced, mildly reduced or preserved, by side as left or right-sided, and by course as chronic or acute decompensated, with diastolic dysfunction a key mechanism in preserved-fraction disease; heart failure is common in older adults and is managed with medicines, devices and lifestyle measures, and worsening symptoms need urgent medical attention.
What it is for: Not applicable; a disease.
It can be route emergencies first; explain types and mechanisms; relay diagnosis and treatment; distinguish related conditions.
Distinguishing features
Pump failure syndrome
Ejection fraction classes
Fluid retention
Chronic with acute episodes
What it looks like
Not a visible object; a syndrome with breathlessness and swelling.
Physical character
prevalence, adults: about 1-2 percent - higher with age
people affected worldwide: about 64 million - estimates
ejection fraction cutoffs: below 40, 41-49, 50 and above percent - HFrEF, HFmrEF, HFpEF
How it is recognised
Heart unable to meet the body s needs
Reduced, mildly reduced and preserved ejection fraction; left and right-sided; chronic and acute decompensated
A heart attack is blocked blood supply; cardiac arrest is the heart stopping
