Key result
A novel noninvasive method for measuring central aortic systolic pressure closely approximated invasive central intra-aortic recordings, with DP/DT values correlating strongly (r = 0.83).
Why the study?
Does a novel noninvasive device accurately measure central aortic systolic pressure compared to invasive central intra-aortic recordings in human subjects?

Effect estimate: r = 0.83
A novel noninvasive method using brachial artery occlusive pressure and ECG timing provides a close approximation of central aortic systolic pressure.
Marmor et al. (1987) reported an observational. Noninvasive measurement of central aortic systolic pressure vs. Invasive central intra-aortic pressure measurement was evaluated on Correlation of DP/DT values between noninvasive and invasive central aortic recordings (r = 0.83). A novel noninvasive method for measuring central aortic systolic pressure closely approximated invasive central intra-aortic recordings, with DP/DT values correlating strongly (r = 0.83).
