Black Patients Fare Worse After Angioplasty

MONDAY, July 6, 2020 (HealthDay News) — Even after undergoing the artery-clearing procedure angioplasty, Black patients with heart disease are more likely than whites to suffer a heart attack or die within the next several years.
That’s the conclusion of a new analysis of 10 clinical trials: On balance, both Black and Hispanic patients fared worse after angioplasty, versus white patients. And that was particularly true for Black patients, whose risk of dying within five years of the procedure was elevated.
The findings are no surprise. For years, U.S. studies have turned up racial disparities in heart disease — including in the risk of dying from it.
The new results “reaffirm” that the racial gap exists, and highlight the need to find solutions, according to senior researcher Dr. Gregg Stone.
He’s a professor of cardiology at Mount Sinai’s Icahn School of Medicine in New York City.
Stone said the study could not weed out the reasons for the worse outcomes among minority patients.
Among Hispanic patients, much of the disparity seemed to be related to higher rates of heart disease risk factors, like diabetes and high blood pressure. But Stone cautioned that might not be the whole story — partly because there were so few Hispanic patients involved in the trials.
Meanwhile, higher rates of risk factors did not account for Black patients’ worse prognosis.
“This is a tremendously complex issue,” Stone said. Many factors could be at work, he explained, from differences in health insurance and financial resources to disparities in patients’ care before or after the angioplasty.
“We need to be able to better understand the causes,” Stone said.
And it’s likely a complicated mix of things, agreed Dr. Michael Nanna, a cardiology fellow at Duke University Medical Center in Durham, N.C.
“Racial disparities, unfortunately, have been documented for decades, and the solution to closing these gaps isn’t straightforward,” said Nanna, who co-wrote an editorial published with the study.
It will require a “multipronged” approach, he said. That means tackling economic disparities that make people more vulnerable to heart disease; lack of health insurance; and unequal access to high-quality health care, to name a few issues.
