What does this research mean for the field?

The Takeda TM-2420 ambulatory blood pressure monitor accurately measures diastolic blood pressure but significantly underestimates systolic blood pressure, making it suitable primarily when diastolic pressure is the criterion of interest.

Implication

Caution advised with TM-2420 systolic readings in practice; leaves open need for device-specific validation studies.

Key Points

To evaluate the measurement accuracy of the Takeda TM-2420 ambulatory blood pressure monitor and TM-2020 data recorder against standard noninvasive and direct intra-arterial methods.
Assessed blood pressure readings from the automated TM-2420 device against simultaneous auscultatory measurements.
Compared automated readings against simultaneous direct invasive femoral artery recordings.
Systolic blood pressure was underestimated by the TM-2420 by a mean of 10 mmHg (SD = 6, 95% CI: -13 to -7) versus auscultation and by 23 mmHg (SD = 12, 95% CI: -28 to -18) versus direct femoral artery recordings.
Diastolic blood pressure measurements matched auscultatory values closely and were overestimated by a mean of 5 mmHg (SD = 4, 95% CI: 3.4 to 6.6) compared to direct femoral recordings.
