Black People Are More Likely Than Whites to Die of Heart Disease. Here’s One Reason Why.

It’s not just diet and lifestyle that determine your risk for heart disease—race matters, too. About 37 percent of white men and 32 percent of white women develop heart disease, versus 44 percent of black men and 49 percent of black women. Overall, the average life expectancy for African Americans is 3.4 years shorter than it is for white Americans, and researchers attribute most of that disparity to the differences in heart disease rates.

The reasons black Americans have higher rates of cardiovascular problems are complicated—among them, as researchers have pointed to, elevated levels of stress as a result of poverty and racism. But a study published today in the journal JAMA Cardiology sheds light on another possible explanation: African Americans are slightly less likely than Caucasians to be given drugs to control their cholesterol levels—and they’re far less likely to be prescribed the correct doses.

A team of researchers from Duke University Medical Center followed the progress of 5,689 patients who were eligible for treatment with statins, a class of cholesterol drug. About 75 percent of the white patients were prescribed statins, compared with 71 percent of African Americans. But when the team looked at dosages, the disparity was starker: About 44 percent of white patients received therapy that followed the guidelines from the American College of Cardiology and the American Heart Association, compared to 33 percent of black patients.

Why are African Americans less likely to get the correct cholesterol treatment? Researchers documented a few possible reasons. For starters, they’re less likely than white patients to see a cardiologist, so their primary care physicians or other providers may not be familiar with the recommendations. In the study, the researchers found, clinicians who saw the black patients were less likely to use the current guidelines in determining a statin dose. “We really looked deeply into the reasons for the disparity, and what we found were a lot of subtle but important differences,” says lead author Michael Nanna, a cardiology fellow at Duke University,

Another key point: African American patients were less likely than white patients to believe that statins were safe and effective, and they also reported significantly less trust in the drugs than their white counterparts. Doctors whose patients express skepticism about the drugs may be less likely to prescribe them, Nanna says.

Experts in the field of cardiovascular health hailed the new research as an important contribution. “It confirms disparities in the use of potentially life-saving medications, and it isolates that the disparities are related to factors that clinicians don’t often consider or measure,” says Keith C. Ferdinand, a professor of medicine at Tulane University who has written about health disparities. He adds, “The overall disparity is real. It directly impacts longevity.”

Craig Umscheid, an associate professor of medicine and epidemiology at the University of Pennsylvania’s Perelman School of Medicine, suggested that future studies might look more closely at black Americans’ mistrust of statins. “Is this a general belief about medications, or is it specific?” he asks. “You can imagine, given the history of medicine, why that might be.” He believes researchers should ask people the same questions about their trust in clinicians.

Duke’s Nanna points out that doctors are under increasing pressure to see more patients in less time, and shorter appointments won’t do much to make sure clinicians are prescribing appropriately or building trust with their patients. “We need to set up health systems where all patients who need treatment get treated,” he says. “If we raise the quality of care for everyone, then everyone benefits, and maybe we can close these treatment gaps.”

AN IMPORTANT UPDATE

We’re falling behind our online fundraising goals and we can’t sustain coming up short on donations month after month. Perhaps you’ve heard? It is impossibly hard in the news business right now, with layoffs intensifying and fancy new startups and funding going kaput.

The crisis facing journalism and democracy isn’t going away anytime soon. And neither is Mother Jones, our readers, or our unique way of doing in-depth reporting that exists to bring about change.

Which is exactly why, despite the challenges we face, we just took a big gulp and joined forces with the Center for Investigative Reporting, a team of ace journalists who create the amazing podcast and public radio show Reveal.

If you can part with even just a few bucks, please help us pick up the pace of donations. We simply can’t afford to keep falling behind on our fundraising targets month after month.

Editor-in-Chief Clara Jeffery said it well to our team recently, and that team 100 percent includes readers like you who make it all possible: “This is a year to prove that we can pull off this merger, grow our audiences and impact, attract more funding and keep growing. More broadly, it’s a year when the very future of both journalism and democracy is on the line. We have to go for every important story, every reader/listener/viewer, and leave it all on the field. I’m very proud of all the hard work that’s gotten us to this moment, and confident that we can meet it.”

Let’s do this. If you can right now, please support Mother Jones and investigative journalism with an urgently needed donation today.
