Heart Failure
Conditions
Brief summary
The purpose of this study is to refine the classification of the effectiveness of the DASH diet for outpatient heart failure (HF) management, using behavioral, clinical, and laboratory correlative science approaches.
Detailed description
The overall objective of this pilot study is to refine the classification of the effectiveness of the DASH diet for outpatient HF management using behavioral, clinical, and laboratory correlative science approaches. The investigators will integrate the use and evaluation of DASH diet nutrition education in a clinical population using a pragmatic study approach. The investigators will assess dietary behavior change. The investigators will assess the medical effectiveness of the DASH diet to improve patient symptomology and clinical biomarkers. Exploratory investigations will involve metabolomics analyses of plasma samples for biomarker discovery of clinical phenotypes in HF patients, to characterize metabolic profiles related to dietary exposure.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Dietary intake | Dietary intake at baseline | Dietary intake assessed by nutrient analysis of food records |
| Diet score | Dietary intake at baseline | Dietary intake assessed by calculation of DASH diet score (Dietary Approaches to Stop Hypertension diet score). Minimum to Maximum values: 8-40 Higher scores mean better outcome and diet composition. |
| Blood Pressure | Systolic and diastolic Blood Pressure at baseline | Blood Pressure assessed with systolic and diastolic pressure |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Heart Failure clinical marker | proBNP at baseline | proBNP will be assessed as a marker of severity of heart failure |
| Patient report of HF symptoms | KCCQ at baseline | Kansas City Cardiomyopathy Questionnaire (KCCQ) will assess patient report of symptoms. Minimum to Maximum values: 0-100. Higher scores represent better outcome. |
| Patient report of eating habit self efficacy | Eating Habits at Baseline | Eating Habits Questionnaire will assess patient report of self efficacy for behavior change around DASH diet eating habits. Minimum to Maximum values:27-135. Higher value is better outcome. |
