Behavior Change in heart failure patients AdetaniaPramanik Durga Kudtarkar Shubhshankar M. Sankachelvi
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
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
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.
Risk Factors Cannot be changed Can be treated
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
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
SRD sodium restricted diet
The Problem • How can we assist HF patients in understanding their appropriate daily • sodium intake and motivate them to • bring about a • behavior change?
