Patients who did not adhere to the SRD of less than 3 g
sodium intake per day had a greater symptom burden and
were approximately twice as likely to experience cardiac
events during a 12-month follow-up period. These findings
could be used by health care providers to help patients
better understand the rationale for an SRD to prevent worsening HF symptoms and unnecessary cardiac events. It
is recommended that patient education should focus on
continuous monitoring for the amount of dietary sodium
intake as well as aggravation of HF symptoms at home.
Randomised controlled trials and prospective studies would
be suggested to establish evidence-based guidelines on an
SRD in clinical area. Also, research-based strategies of
patient education specific to an SRD would be modifiable
and applicable to warrant preventable cardiac events in
clinical practice.
