SRD Significancesodium 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
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
BackgroundFunctional classification (NYHA): Four stages of HF(ACC / AHA):
Class I: no limitation is experienced in any activities; there are no symptoms from ordinary activities.
Class II: slight, mild limitation of activity; the patient is comfortable at rest or with mild exertion.
Class III: marked limitation of any activity; the patient is comfortable only at rest.
Class IV: any physical activity brings on discomfort and symptoms occur at rest.
Stage A: high risk for HF but no functional or structural heart disorder
Stage B: a structural heart disorder but no symptoms at any stage
Stage C: an underlying structural heart problem, but managed with medical treatment
Stage C: an underlying structural heart problem, but managed with medical
Stage D: hospital-based support, a heart transplant or palliative care.
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
SRDsodium 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
