Clinical research needs you

Women & minorities are underrepresented in clinical research

Why you should participate in a cardiovascular device trial

Clinical research should reflect the population it intends to treat

By participating you can help in the development of lifesaving treatments

Play a part in advancing innovation in medical devices

Gender and ethnic differences matter in treatment of heart valve disease

52% of women surveyed experienced heart valve disease symptoms1

Low-income patients receive less care2

Women are less likely than men to receive treatment for symptomatic severe aortic stenosis (AS)3

Different risk profiles.
Different treatment outcomes.

With your help participating in Clinical Trials, we can explore whether a treatment approach or device is safe and effective. Data show that women are getting referred later than men4, and increasing female participation is critical to improving our understanding about the effects of new treatments for women and saving lives.

We need you.

Have similar Aortic Stenosis severity with less valve calcification More severe exertional dyspnea Higher frailty
different risks infographic Women5-7
Women scheduled for Aortic Valve replacement were significantly older Smaller body size.
Smaller valve size
More severe AS

Effectiveness and safety may differ among population subgroups depending on intrinsic/extrinsic factors, including:

Did you know?

More ethnic minority participation is needed in clinical trials

With your help we can do better...

Representation across 178 cardiovascular clinical trials9

White 73%
Hispanic or Latino 11%
Asian 10%
Black or African American 4%
Other 2%

Although Edwards has increased diverse ethnic participation in the PARTNER series clinical trials from 2007-2017, there is still more progress to be made.
