Why the study?

Which standard cardiovascular autonomic reflex tests and indices are most useful for assessing autonomic function in elderly subjects?

Structured PICO

Which standard cardiovascular autonomic reflex tests and indices are most useful for assessing autonomic function in elderly subjects?

Population

273 subjects, comprising 224 healthy controls and 49 aged diabetic patients (age ≥ 50 years)

Intervention

Standard cardiovascular autonomic reflex tests (Valsalva manoeuvre, active orthostatic test, deep breathing test, isometric handgrip test)

Outcome

Usefulness of various autonomic indices based on age-related reference valuessurrogate

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Standard cardiovascular autonomic reflex tests can be used in the elderly, but indices based on heart rate differences are preferred over R/R interval ratios.
