Systemic blood pressure, arterial stiffness and pulse waveform analysis at altitude.

Abstract:

OBJECTIVES: Systemic arterial pressure rises on acute exposure to high altitude and changes in blood pressure (BP) and endothelial function may be important in the pathogenesis of clinical syndromes occurring at high altitude. METHODS: Arterial BP, stiffness (SI) and tone (RI) were studied over 11 days in 17 subjects (three having mild hypertension) ascending to 3,450m and 4,770m using a non-invasive, finger photoplethysmography technique. RESULTS: At 3,450m BP rose from mean 131/75 mmHg (SD...
