class	content of evidence	The evidence level	Recommended level
Multidisciplinary teamwork	1. Multidisciplinary teamwork in chronic heart distress patients should include: attending doctors with specialist heart failure training, heart distress specialist nurses, and healthcare professionals with expertise in prescribing heart failure specialists.	IIIa	B
Multidisciplinary teamwork	2. Educational programs involving multidisciplinary teams can improve treatment dependency and self-care capacity among patients with chronic cardiac distress and caregivers.	Ib	B
Health education	3. Patients were educated to self-manage diuretic and fluid intake and to monitor body quality and urine volume. If the body mass is found to increase continuously (such as 2 kg on 3 days), it indicates that the volume overload urine capacity and body mass can directly reflect the changes of the condition, identify the symptoms of heart failure and the manifestations of acute aggravation, and go to the hospital as soon as possible.

Health education	4. Health education for patients and caregivers with chronic heart failure to improve treatment dependence and self-care can help to improve patient quality of life [4] .	IIa	B
	5. Health education for CHF patients and caregivers may improve their quality of life and physical and mental well-being.	IIb	B
Capacity management measures	6. It is necessary to dynamically evaluate the capacity management status and change the capacity management objectives in time [5] [6] .	Ia	A
Capacity management measures	7. Patients with chronic stage D heart failure can control their fluid intake at 1.5 - 2.0 L/d or set fluid intake based on body mass at 30 mL/kg for patients with body mass < 85 kg and 35 mL/kg for patients with body mass > 85 kg/mouth.	IIa	A
	8. Avoid excessive salt and sauces, such as soy sauce, chili sauce, pickled meat, noodles, pickles, biscuits, etc.	IIa	B
	9. Patients with chronic heart failure should use diuretics in the early stages of fluid retention. Usually from small dose application, gradually increase the dose to congestion symptoms and signs, for disease control (lung rale disappear, edema subsided, the body mass stability), namely with the minimum effective amount for a long time, and according to the dose at any time, the goal is to maintain the lowest effective diuretic dose “dry body mass”.	IIa	A
Follow-up	10. A heart failure follow-up system should be established to provide structured telephone follow-up and non-invasive remote monitoring for home-based CHF patients [7] .	IIb	B
Follow-up	11. Establish a follow-up system for heart failure. Recommend follow-up once every 2 weeks, and adjust to follow-up once every 1 - 2 months after the condition is stable.	IIIa	B
