IndyCar Series star Danica Patrick, who will drive the number 7 Chevrolet in a limited NASCAR schedule in 2010, has recently joined on as a spokesperson for DRIVE4COPD, a public health initiative aimed at alerting million of Americans about the need for early detection of Chronic Obstructive Pulmonary Disease (COPD).

Patrick was drawn to the cause due to the close relationship that she had with her grandmother, who passed away in her mid 60’s after suffering from emphysema, one of the two forms of COPD, according to USA Today.

“Being a popular person followed by a lot of fans gives me a platform I can use for good things,” said Patrick, while participating in a photo shoot for the organization with fellow celebs Jim Belushi, Bruce Jenner, Patty Loveless and Michael Strahan. “I want to use my celebrity to make a difference.”

Meanwhile, NASCAR has also decided to partner with DRIVE4COPD, which will be the title sponsor for the season-opening Nationwide Series race at Daytona Motor Speedway.

COPD currently affects approximately 24 million people, half of whom are undiagnosed, says Steve Phelps, senior vice president and chief marketing officer for NASCAR.
