Participate in a clinical cardiovascular research trial

Ride the cutting edge of healthcare 

Our clinical cardiovascular research program, developed in 2006, has a state-inspected and approved research center based at Northern Arizona Healthcare’s Verde Valley Medical Center in Cottonwood, but our studies are held at multiple sites throughout the world. Studies focus on heart disease; heart attacks; peripheral arterial disease, or PAD; high blood pressure; cholesterol management; and diabetes. This work often involves teaming up with universities such as Harvard, Duke and Oxford; the National Institutes of Health; and other institutions on the cutting edge of research.

Our award-winning program is recognized by study sponsors for high recruitment and retention. In North America (the United States and Canada), our program has been ranked as the sixth highest enroller out of 168 REVEAL study sites.  Our site randomized 93 subjects compared to the average of 36 subjects at other North American sites. We have also been recognized as a top enroller and leadership site in the ACCLERATE trial and ARTEMIS study, and named one of the top 10 overall enrolling sites in the CIRT study. In five years, our program has grown from 100 to more than 300 study participants and has maintained a 99 percent retention rate of participants throughout the entire length of a study.
