Variabilidade da frequência cardíaca em pacientes com anemia ferropriva

background: heart rate variability (hrv) is associated with increased cardiac risk factor in several conditions. the iron status of an individual may play an important role in cardiovascular health. objective: to evaluate heart rate variability in patients with iron deficiency anemia. methods: twenty-three patients with iron deficiency anemia (mean hemoglobin (hb) 8.6±2.2 g/dl) and 10 healthy people (mean hb 13.9±1.2 g/dl) were assessed with 24-hour ambulatory holter recordings during in hospital course having limited physical activity. results: although mean heart rate was significantly higher in patients with anemia, there was no significant difference regarding hrv parameters compared to the healthy group. conclusion: there was no significant difference in hrv parameters between patients with iron deficiency anemia with limited physical activity and healthy ambulatory people.
