We are learning more about the long-term effects of COVID
By INTERMOUNTAIN HEALTHCARE
The study found that individuals who tested positive for COVID-19 had a
higher likelihood of experiencing chest pain in the six months to a year
following the infection.
Even patients with mild COVID-19 infections can suffer from health
complications for months, even years, post-infection. Nearly 19% of U.S. adults
who had previously tested positive for COVID-19 report having “Long COVID,”
where they experience signs and symptoms for four weeks or more after the
initial phase of infection.
In an effort to quantify what Long COVID means now, and could mean in the future for these patients, researchers from Intermountain Health in Salt Lake City studied nearly 150,000 patients for cardiovascular symptoms.

“Many COVID-19 patients experience symptoms well beyond the acute phase of infection,” said Heidi T. May, PhD, cardiovascular epidemiologist at Intermountain Health and principal investigator of the study.
“While we didn’t see any significant rates of major
events like heart attack or stroke in patients who had an initial mild initial
infection, we did find chest pains to be a persistent problem, which could be a
sign of future cardiovascular complications.”
Results of the Intermountain study were
presented at the American College of Cardiology’s 2023 Scientific Conference in
New Orleans.
In the large retrospective study,
researchers compared three groups of Intermountain Health patients:
- 148,158 people ages 18 and up who
tested positive for COVID and treated in an outpatient setting from March
2020 to December 31, 2021.
- 148,158 Intermountain COVID
negative patients of about the same age and gender, seen in the same
months, as those who tested positive for COVID-19.
- 148,158 patients seen between
January 1, 2018, and August 31, 2019, as a historical control, to account
for how patients accessed healthcare different during the worst of the
pandemic.
The Intermountain research team found
that at six months and one-year intervals, patients who tested positive for
COVID-19 had significantly higher rates of experiencing chest pain, but saw no
other increases in cardiovascular events.
“As of right now, the symptoms aren’t necessary translating into hard outcomes, but that’s something that will need to be reassessed over time,” Dr. May said.
“It could be that lasting effects of
infection on the cardiovascular system are hard to quantify in terms of
diagnoses or other events in the short-term and won’t be realized until longer
follow up.”
