Clinical Scorecard: Decreased heart rate variability as a predictor of new-onset diabetic polyneuropathy

At a Glance

Key Highlights

• CAN prevalence was 16.3% among participants with DM.
• Low HRV indices were found in 18.6–40.2% of participants.
• Baseline CAN independently predicted incident DSPN with adjusted HRs ranging from 3.30 to 7.33.
• Incident DSPN rates were 8.4, 5.7, and 3.3 per 100 person-years across different definitions.
• Reduced HRV provides a practical marker for identifying individuals at risk for DSPN.

Guideline-Based Recommendations

Diagnosis

• Utilize cardiovascular autonomic reflex tests and HRV indices for assessing risk of DSPN.

Management

• No specific therapy exists to reverse DSPN; focus on early identification of high-risk individuals.

Monitoring & Follow-up

• Follow-up assessments for HRV and CAN in individuals with DM to predict DSPN development.

Risks

• Older age, poor glycaemic control, adiposity, longer diabetes duration, and increased urinary albumin excretion are associated with both CAN and DSPN.

Patient & Prescribing Data

Individuals with type 1 and type 2 diabetes mellitus.

Screening for CAN and HRV may aid in identifying patients at risk for DSPN.

Clinical Best Practices

• Incorporate HRV assessments in routine evaluations for patients with diabetes.
• Educate patients on the importance of monitoring for symptoms of DSPN.
