Exploring the Barriers and Enablers to Implementing a 16-Week Low-Carbohydrate Diet for Patients With Diabetic Cardiomyopathy.

AIMS

Cardiac dysfunction in patients with diabetes, referred to as diabetic cardiomyopathy, is primarily precipitated by dysregulations in glucose and lipid metabolism. Diet and lifestyle changes are considered crucial for successful heart failure and diabetes management and are often difficult to achieve. Low-carbohydrate diets (LCDs) have gained popularity for the management of metabolic diseases. Although quantitative research in this field is evolving, little is known about the personal experience of patients with diabetic cardiomyopathy on specific diets. The aim of this qualitative study was to identify enablers and barriers of patients with diabetic cardiomyopathy who engage in an LCD. It further explored patients' perception of dietary education and dietary support received while in hospital.

METHODS AND RESULTS

Participants who previously consented to a 16-week LCD trial were invited to share their experiences. Nine patients agreed to be interviewed. Semistructured interviews and a focus group interview were conducted, which were transcribed verbatim. Data were analyzed by using the 6-step approach for thematic analysis. Four themes were identified: (1) nutrition literacy (2) disease-related health benefits, (3) balancing commitments, and (4) availability of resources and support.

CONCLUSION

Improvements in disease-related symptoms acted as strong enablers to engage in an LCD. Barriers such as access to resources and time constraints were identified. These challenges may be overcome with efficient communication and ongoing dietary support. More research exploring the experience of patients with diabetic cardiomyopathy on an LCD are warranted.
