Heart ******** is rampant in parts of the rural South. Researchers are hitting the road to learn why

Darrell Dixon’s father was just 25 when he had a major heart ******* in the rural Mississippi Delta. By his early 40s, a series of additional attacks had left his heart muscle too weak to pump enough blood to his body. He ***** in 2013 at the age of 49.

“It was a big jolt for our family,” Dixon, 36, recalled. “For myself, personally, it also got me thinking about heredity. I just wondered whether I was next.”

The ****** spurred Dixon to get involved in an unusual and ambitious new health study.

Public health experts from some of the nation’s leading research institutions have deployed a massive medical trailer to rural parts of the South to test and survey thousands of local residents. The goal: to understand why the rates of heart and lung ******** are dramatically higher there than in other parts of the U.S.

“This rural health disadvantage, it doesn’t matter whether you’re white or ******, it hurts you,” said Dr. Vasan Ramachandran, a leader of the project who used to oversee the

— the nation’s longest-running study of heart ********. “No race is spared, although people of ****** fare worse.”

The researchers aim to test the heart and lung function of roughly 4,600 residents of 10 counties and parishes in Alabama, Kentucky, Louisiana and Mississippi while collecting information about their environments, health history and lifestyles. They are also giving participants a fitness tracker and plan to survey them repeatedly for years to check for any major medical events.

Ramachandran, now dean of the University of Texas School of Public Health in San Antonio, said rural populations in the U.S. rarely receive such personal, long-term attention from epidemiologists. More than a dozen institutions are helping with the study, including Johns Hopkins University, the University of California, Berkeley, and Duke University.

The 52-foot-long (16-meter-long), 27-ton trailer is outfitted with instruments that examine calcium in the arteries, the structure of the heart, lung capacity and other, more common health indicators such as blood pressure and weight. The initial exam can take more than three hours.

“They’re reaching out and going out into the community in ways that I have not seen before,” said Lynn Spruill, the mayor of Starkville, Mississippi, in Oktibbeha County, where the trailer arrived in 2022 and medical staff tested more than 700 people.

and have lower life expectancy than Americans in urban areas. The health disparity is even greater in the South, where mortality rates from heart ******** — the leading cause of ****** in the U.S. — for people 35 and older are more than twice the national average in some rural communities. Lung conditions such as chronic obstructive pulmonary ********, or COPD, which the study is also examining, are also more prevalent in the South.

Researchers have multiple theories for the disparity. Hospital closures and physician shortages have left many rural residents with limited access to care. Healthy food, fitness opportunities and public transit are often scarcer. ******** rates are higher, and fewer people receive health coverage through their employers. In the rural South, ******** rates and the share of people without health insurance are even greater.

, according to 2019 data from the U.S. Centers for ******** Control and Prevention. Obesity is another factor. In 2022, self-reported height and weight put between 38% and 40% of adults in the

in the obese body mass index category.

By closely examining local residents and their environments, the rural study seeks clearer answers about what’s driving the additional health burden in the South. Researchers also want to understand what makes some rural counties there much healthier than others.

“We’re interested in both the risk, but also the resilience piece of it,” said Lindsay Pool, an epidemiologist with the National Heart Lung and Blood Institute, which has awarded more than $40 million for the study.

To accomplish that goal, researchers are also visiting rural areas with low risk for heart and lung ******** in three of the states — Louisiana, Mississippi and Kentucky — despite similar demographics.

Oktibbeha County, home to Mississippi State University, in the eastern part of Mississippi near the Alabama border, is the low-risk location. The researchers are contrasting it with Panola County in northern Mississippi about 60 miles (97 kilometers) south of Memphis, Tennessee.

Both counties have ******** rates that exceed 20% and a similar and sizeable share of people under 65 without health insurance. But between 2019 and 2021, the ****** rate from heart ******** for those 35 and over was 647 per 100,000 people in Panola County compared to 395 per 100,000 in Oktibbeha County, according to

.

In more urban Rankin County, Mississippi, part of the Jackson metro area, the figure was 331. The U.S. average over the same ******* was 326.

Dixon, who works in Panola County for a regional development organization and serves as a consultant for the heart and lung study, helped recruit more than 600 Panola County residents for the project. Heart conditions are so prevalent there that it’s common to hear people discussing their medications and side effects at local shops and churches, he said.

Dixon’s father, Darrell Dixon Sr., lived in Clarksdale, about 40 miles (64 kilometers) west of Panola County. He long suffered from high blood pressure and had a strong family history of heart ********.

He had an additional major heart ******* after an inmate he had grown close to as chaplain of the Mississippi State Penitentiary was *********, Dixon said, and then spent the last years of his life in and out of the hospital with congestive heart ********.

“He really suffered,” Dixon said. He hopes the study will shed light on any unseen environmental factors that may have played a role in his dad’s ****** and raise awareness among local residents about “how to live better.”

The trailer is now in Louisiana’s northeastern Franklin Parish, where the ****** rate from heart ******** between 2019 and 2021 was a whopping 859 per 100,000 people for those 35 and over, according to the CDC data. About 200 miles (322 kilometers) south in New Orleans, it was 340.

The National Heart, Lung and Blood Institute plans to extend the study to 2031, and researchers hope to examine all the participants in person again.

“The longer you can follow people, the more you can understand ******** development and progression,” Pool, the epidemiologist, said.
