Q: I have been reading about a device (FDA approved) called Cardio Beam Meridian DPA. Literature states that it is an arterial scan and measures the loss of arterial compliance. Is this non-invasive product of value?
A: Digital Pulse Analyzers are thought to be able to predict a future heart attack or stroke by measuring the elasticity of large and small arteries. If irregularities in the arteries are picked up early, therapeutic measures could be taken that might prevent future disease. Whether or not this technology will prove to be both cost effective and improve long-term outcomes remains to be seen.
