Clinical Research

The University of Arizona Sarver Heart Center is enrolling patients for several clinical research trials to improve patient care for several cardiovascular diseases. Please complete a Cardiology Research Registry Information Form to learn about new clinical research studies for which you may be eligible.

What is a Clinical Trial?

Patient care advances rely on good clinical research. Clinical trials are research studies that explore whether a medical strategy, treatment or device is safe and effective for humans. These studies also may show which medical approaches work best for certain illnesses or groups of people. Clinical trials produce the best evidence to guide health care decisions.

The National Heart, Lung and Blood Institute, part of the National Institutes of Health, is an important funding source for heart research in the United States. Below is information from their website, which provides additional information on who sponsors clinical trials, how they work and what people should expect when they participate in a clinical trial.

Be Part of Something Big to Help Beat Heart Disease

Thanks to a great response from the community, Sarver Heart Center has enrolled more than the 200 participants in its Cardiac Biorepository. Please help us reach our goal of enrolling100 people each year.

"These blood samples will help scientists better understand heart disease to improve care and treatment now and in the future," said Nancy Sweitzer, MD, PhD, director of the Sarver Heart Center and principal investigator of the biorepository research program.

Most of the enrollment process for the Biorepository will be done online to align with Covid-19 precautions. However, a blood draw will be scheduled to coincide with a clinically necessary visit.

To participate, you'll complete a questionnaire, sign an informed consent form that allows researchers to view your electronic medical record, and donate about 3 tablespoons of blood. Click on the Cardiology Research Registry link to complete the form.

An Institutional Review Board responsible for human subjects research at The University of Arizona reviewed this research project and found it to be acceptable, according to applicable state and federal regulations and University policies designed to protect the rights and welfare of participants in research.

This won’t take much – just three tablespoons of your blood, about the amount taken during a standard blood draw. This small amount will help us ask bigger questions and get better answers as we move toward a future free of heart disease and stroke. You don’t have to have heart disease to be part of this big venture. You just need to be at least 18 years old. Learn more.
