- Abstract
Introduction: Heart rate recovery (HRR) immediately after the exercise stress test is considered a reflection of the vagal reactivation and a marker for autonomic imbalance. Materials and methods: We performed a retrospective analysis on 31 patients with abnormal HRR studying the influence of the most important cardiovascular risk factors: smoking, diabetes, obesity and hypertension as determinants for autonomic imbalance. Results: There was no association between the major risk factors with the ΔHR1, which only seems to be correlated with the maximal load of the stress test. For sub-groups with lower cut-off values for HRR and aged above 75 we obtained several correlations with smoking status, diastolic blood pressure and obesity. Conclusions: Even though our study group is small, our findings still raise the question if we should be more strict when considering the HRR abnormality with a possible cut-off value of 8/9 for each of the minutes of recovery.
