Researchers at University of Arizona Health Sciences and Northwestern University sought to answer the question as to the promise of wearable technology for blood pressure monitoring.   The research effort is titled “Relation between blood pressure and pulse wave velocity for human arteries.”

Only about 50 percent of those in the United States that have been diagnosed with blood pressure have it in control. The investigators are pursuing an important effort as commercializing an economical and efficient way to monitor blood pressure would be of tremendous help in mitigating cardiovascular disease risk.

According to the Centers for Disease Control (CDC), high blood pressure is deadly. For example, approximately 75 million American adults have high blood pressure—that equates to 1 in 3 adults. Moreover almost 1 in 3 adults has prehypertension—blood pressure numbers higher than normal. Research evidences that only about half of the American population diagnosed with high blood pressure have it in control. 1,100 people die daily in America due to high blood pressure-related disease. High blood pressure financially impacts the United States in the order of $48.6 billion annually.

The researchers found that “pulse wave velocity” (PWV)— the speed by which the impulse or blood moving away from the heart moves down the arteries represents promise as a measurement to monitor blood levels lead researcher Marvin J. Slepian, MD reported(see investigator profile below). The researchers conclude that a continuous and non-invasive blood pressure monitoring—derived from the measurement of the pulse wave velocity—is a promising approach for non-invasive measurements. A big opportunity exists if this approach could be somehow tested in rigorous, FDA controlled clinical trials and thereafter commercialized.
