vasometrix is to blood pressure monitoring as the iphone is to telephony: making phone calls is not its top treasured talent.

Dr. Lutz E. Kraushaar

"A man is as old as his arteries."

Thomas Sydenham, 1624 - 1689

The Problem

Atherosclerotic disease goes hand in glove with a progressive decline of vascular function.

But so does aging.

To differentiate between the two is beyond the capability of clinical practice.

The result: underestimation of future cardiovascular morbidity and mortality in young adults, overestimation of risk in older adults, and poor efficiency in preventing CV disease mortality (Wald, Simmonds, & Morris, 2011).

"…traditional risk factors fail to predict future CVD in up to 50% of cases."

Prof. Dick H.J. Thijssen, J. Physiol 594.8

The Challenge

To develop a non-invasive assessment of all the parameters that define vascular function (Pereira, 2016; D. H. Thijssen, Carter, & Green, 2015).

Because the two surrogates that we have (pulse wave velocity, PWV; and flow mediated vasodilatation, FMD) correlate poorly with what they are supposed to measure

(Lutz E. Kraushaar, Dressel, & Massmann, 2018).

Functionomics is to aging what genomics is to inheritance. With one fascinating difference: You can change your functionome.

The Solution

…vasometrix, with its 3 strategies​:

  1. "functionomic" profiling for all relevant physical parameters of global vascular function.

  2. translating the functionomic profile into vascular biological age.

  3. doing number 1 & 2 "on the cheap": that is, by using conventional blood pressure monitoring (BPM) devices to extract functionomic data and BioAge.

Which makes for an attractively cost effective, user-friendly  and scalable solution.

In a nutshell:

vasometrix equips conventional  BPM devices with cutting-edge diagnostics for cardiovascular risk, function and age.

The Benefits.

  • For pharmaceuticals and clinical research: substantial reductions in costs and durations of phase III and other clinical trials.

  • For BPM device manufacturers: a unique competitive selling point.

  • For public health: low-cost scalability and the resulting prospect of substantial reductions in CVD morbidity and mortality.

How it works


your digital "avatar".

You "feed" him a recording of your pulse pressure wave, he replicates it, and returns a precise analysis of your vascular function.

I helped conceive and test this avatar and I named it "arteroid", a 721-element Windkessel electronic replication of the human arterial tree.


Arteroid's (digital) DNA: the electric-hydraulic analogy.


It states that each and every parameter of the tree's hemodynamic function has an exact electronic equivalent.

Once you know either one, you automatically know the other.

  • resistance = resistance,

  • arterial compliance = capacitance,

  • pressure = voltage,

  • flow = current,

  • inertia = inductance.

Why it is so accurate

Using evolutionary algorithms, the arteroid manipulates these electronic equivalents to replicate a person's non-invasively acquired pulse pressure curve with high fidelity (typically >99%).

The resulting electronic parameters represent their hemodynamic equivalents. 

That's how to uncover the functional profile of a person's arterial vasculature.


For a detailed description refer to appendix 1 of (Lutz E. Kraushaar, Dressel, & Massmann, 2018).


It's the functional equivalent of genomics: a person's individual functionome.

arteroid's strength is its greatest weakness

Arteroid's handicap: the required computing time and the hardware cost.

They make it too slow and too expensive for routine clinical practice.


That's why I conceived of vasometrix.

Think of vasometrix as the arteroid's clone:


A proprietary algorithm that replicates the arteroid's capabilities.


But at a fraction of arteroid's cost and time, and,…

…better still,…


…vasometrix can be calibrated to the pulse pressure wave recordings of ANY conventional BPM device.
