SRD Significance

sodium restricted diet

  • 25% of heart failure (HF) related patients were readmitted

  • Limiting sodium intake is one of the ways of readmission prevention for HF patients.

  • However, it is difficult for patients to understand how to manage and change their daily sodium intake


Behavior change

Background

Heart Failure

  • Most common cause HF: coronary artery disease (narrowing the blood vessels that supply the heart)

  • Conditions that contribute to HF: obesity, diabetes, smoking, hypercholesterolemia, hypertension,…

  • Is a progressive, chronic disease


Behavior change

Background

  • Functional classification(NYHA):

  • Four stages of HF(ACC / AHA):

  • Class I: no limitation is experienced in any activities; there are no symptoms from ordinary activities.

  • Stage A: high risk for HF but no functional or structural heart disorder

  • Class II: slight, mild limitation of activity; the patient is comfortable at rest or with mild exertion.

  • Stage B: a structural heart disorder but no symptoms at any stage

  • Class III: marked limitation of any activity; the patient is comfortable only at rest.

  • Stage C: an underlying structural heart problem, but managed with medical treatment

  • Stage C: an underlying structural heart problem, but managed with medical

  • Class IV: any physical activity brings on discomfort and symptoms occur at rest.

  • Stage D: hospital-based support, a heart transplant or palliative care.

Treatment Plan

Nutritional Diet

  • Sodium intake < 3,000 mg/day

  • Lesser HF symptoms

  • What does 1500, 2300 or 3000 mg/day mean?

  • Low salt doesn’t mean low sodium


Behavior change

SRD

sodium restricted diet

  • Understanding sodium content of food

  • Lack of food selection

  • Food preparation habits

  • Fast foods and convenience products

  • Understanding the symptoms of HF

  • Literacy

  • Co-morbidities

  • Depression: worse self-care & poorer prognosis
