The aim of the study was to evaluate hemodynamic responses after tilt reversal in familial amyloid polyneuropathy (FAP). Systolic blood pressure (BP) and heart rate variability (HRV) were analyzed in the baseline, 70-degree upright position, and after tilt reversal in 10 patients with FAP and 14 healthy controls. Maximum systolic BP after tilt reversal was increased in FAP as compared to baseline (BP overshoot), whereas controls showed a significantly lower BP overshoot. In all states, all HRV parameters were significantly lower than those of the controls. In a linear regression analysis adjusted for age, we found a significant inverse relation between BP overshoot and HRV in all three states. Five patients presented atrial arrhythmia precluding HRV analysis: four of those presented BP overshoots 12 mmHg. BP overshoot may be a useful marker to assess the progression of cardiac autonomic dysfunction, especially since heart arrhythmia in many patients with FAP prevents HRV analysis.
