Behavior Change in heart failure patients Adetania Pramanik 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. 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.
