In Parkinson’s disease (PD), cardiovascular dysautonomia accumulates with disease progression, but studies are lacking on the natural history behind each subtype except orthostatic hypotension. This study investigated the early natural history of orthostatic blood pressure (BP) subtypes in PD. Two hundred sixty-seven early PD patients were included. Their cardiovascular functions were assessed by head-up tilt-test and123I-metaiodobenzylguanidine scintigraphy. All patients were classified as having supine hypertension (SH), orthostatic hypertension (OHT), delayed orthostatic hypotension (dOH), or orthostatic hypotension (OH) according to consensus criteria. The patients were assigned to one of three groups: extreme BP dysregulation (BPextreme), mild BP dysregulation (BPmild), and no BP dysregulation (BPnone) according to their orthostatic BP subtypes. The autonomic functions of 237 patients were re-assessed after approximately 3 years. Among initially enrolled subjects, 61.8% of the patients showed orthostatic BP dysregulation: 29.6% in the BPextremegroup and 32.2% in the BPmildgroup. At follow-up, the BPextremegroup increased in number, while the BPmildgroup diminished. Two-thirds of the initial BPextremepatients maintained their initial subtype at follow-up. In comparison, 40.7% of the initial BPmildpatients progressed to the BPextremegroup, and 32.4% and 14.7% of the initial BPnonegroup progressed to BPextremeand BPmildgroups, respectively. Cardiac denervation was most severe in the BPextremegroup, and a linear gradient of impairment was observed across the subtypes. In conclusion, various forms of positional BP dysregulation were observed during the early disease stage. SH and OH increased with disease progression, while OHT and dOH decreased, converting primarily to SH and/or OH.
