About this episode

Dr. Tariq Ahmad discusses the inconclusive evidence surrounding sodium restriction in heart failure and the need for more personalized dietary guidance.

Is sodium restriction in heart failure evidence-based—or just tradition? Dr. Tariq Ahmad explains why inpatient and outpatient data remain inconclusive, why a VA review found no support for restricting sodium in hospitalized HF patients, and how the field can move toward pragmatic trials and more personalized guidance. The conversation also highlights the risk of overemphasizing diet while underemphasizing proven therapies like GDMT.
