The study covered in this summary was published on as a preprint and has not yet been peer-reviewed.

Key Takeaways

  • More than 40% of participants with COVID-19 reported cardiac-related postacute sequelae SARS-CoV-2 infection (PASC) symptoms over a mean of 12 months.

  • The prevalence of new cardiovascular (CV) risk factors and cardiac conditions after COVID-19 infection was 27%.

Why This Matters

  • This study demonstrates an association between COVID-19 infection with a worsening prognosis of existing CV risk factors and increased risk for CV complications.

  • There is a need to improve access to care and awareness of cardiac-related PASC symptoms in patients with a history of COVID-19.

Study Design

  • A cross-sectional analysis assessed adults who tested positive for COVID-19 and were in the Johns Hopkins COVID-19 HOPE registry as of November 2021. Outcomes were self-reported cardiac-related PASC.

  • Exclusion criteria include pregnancy and the inability to provide informed consent.

  • Stepwise multivariable logistic regression was conducted to assess the association between risk factors (existing cardiovascular disease [CVD], pre-existing conditions, days since positive test, COVID hospitalization, age, sex, education, income) and cardiac-related PASC.

Key Results

  • The analysis involved 442 adults (mean age, 45.4 years; 71% female), of whom 13% identified as Black, 46% reported pre-existing conditions, 23% had CV risk factors, and 4% had CVD.

  • The median time since infection was 12.4 months, about 10.5% of participants were unvaccinated, and 12.0% reported being hospitalized for COVID-19.

  • The prevalence of persistent cardiac-related symptoms and newly diagnosed cardiac conditions was 43.0% and 26.9%, respectively.

  • Heart palpitations was the most commonly reported cardiac-related symptom at enrollment, compared with the 2 weeks postacute COVID (22.6% vs 14.5%; P < .05), followed by tachycardia (20.6% vs 12.9%; P < .05).

  • Of the newly diagnosed cardiac conditions, 24% were tachycardia, 20% were hypertension, and 13% were postural orthostatic tachycardia syndrome.

  • The adjusted odds for cardiac-related PASC were 2.01 higher (95% CI, 1.27 – 3.17) in participants with underlying CV risk factors and CVD.

  • The adjusted odds for cardiac-related PASC were also higher among participants with underlying pre-existing conditions (odds ratio [OR], 2.00; 95% CI, 1.28 – 3.10) and those who were hospitalized (OR, 3.03; 95% CI, 1.58 – 5.83).


  • Causal inference cannot be determined because of lack of temporality.

  • Data are based on self-report, with nonascertainment of reported CVD diagnosis or symptoms through EMR chart review.

  • Most of the participants were never hospitalized for COVID-19 and have not addressed their conditions through health systems.


  • Funding was supplied in part by the National Heart, Lung, and Blood Institute, as part of the NIH Community Engagement Alliance Against COVID-19 Disparities.

  • The authors declared no competing interests.
