Abstract

Background: Idiopathic hypotension is not uncommon among young individuals, yet it is not well studied. Hypotension affects quality of life because symptoms are often accompanied by anxiety, depression, and low motivation. The aim of this study was to assess the effectiveness of the new Inferum NBP-050 device in correcting blood pressure in symptomatic hypotensive patients.
Results: The study included 43 symptomatic hypotensive patients. Demographics, symptom analysis and risk factors as well as office and ambulatory blood pressure measurements were assessed at baseline. Patients were instructed to use the Inferum device at home on the dorsal surface of their left wrist for 6 minutes, twice daily for 14 consecutive days. Symptoms and blood pressure were reassessed after 14 days and then after 3 months of using the device. At 14-days follow up, the median baseline office systolic and diastolic blood pressures had increased from 85 to 104.5 mmHg (P<0.001) and from 52 to 66.5 mmHg (P<0.001) respectively and the median baseline 24-hours ambulatory systolic and diastolic blood pressures had increased from 88 to 103 mmHg (P<0.001) and from 51 to 66 mmHg (P<0.001) respectively. Most patients (88.4%) claimed marked improvement or even disappearance of symptoms after 14 days of device use. Follow up after 3 months showed comparable results to the 14-days follow up visit.
Conclusions: The new device Inferum NBP-050 was effective in improving low blood pressure in symptomatic patients with idiopathic hypotension. The effect was apparent after 14 days of device use and it persisted for 3 months thereafter.
