Clinical Trials

There are over 60 CV Medicine Faculty  engaged in a wide variety of clinical research protocols investigating new approaches to preventing and treating conditions and diseases in cardiac patients.   Our clinicians are recognized internationally for research programs in cardiology, cardiovascular interventional procedures, regenerative medicine, structural heart disease, women’s health, arrhythmias, heart failure, hypertension and amyloidosis to name a few.  These trials are conducted in close collaboration with scientists and physicians from many areas of expertise across Stanford University.

The CV Medicine Clinical Research Program supports Faculty to  Enhance the ability to conduct clinical research.

The Program provide resources, expertise and best practices to facilitate proficient, compliant and ethical study conduct and management from protocol development to trial facilitation and post-trial assessment and reporting.

What Is a Clinical Trial?

Clinical trials are tests of drugs or medical devices to determine if they are safe to be used on humans and whether they are effective. The government requires clinical trials be conducted and evaluated before drugs are approved for human use. Before any drug or device can be administered or used by anyone, the sponsor must provide the FDA with the results of laboratory and animal research. Once approval is given the clinical trial process can begin.

Clinical trials are at the heart of all medical advances. They represent hope and the latest advancements in Cardiovascular Medicine treatment. In CV Medicine, we conduct more than 100 active clinical trials every year; from drug and device treatments to digital health solutions.


If you or your loved ones have been diagnosed with a Cardiovascular disease, you deserve to know about the latest in care. For that, we have developed a Research Registry that will allow you find active clinical trials that match your needs.

Patients will be randomized to either completing a patient-reported outcome survey each visit that is shown to their heart failure clinician, or usual care in which the clinician performs the standard interview without the questionnaire. The standardized questionnaire is the Kansas City Cardiomyopathy Questionnaire (KCCQ), a 12-question multiple-choice survey. This instrument has been shown to capture heart failure symptom severity and predict prognosis. We will evaluate whether using the KCCQ-12 during routine clinic visits impacts health status or treatment patterns at 1 year.
