New Analysis Hyperlinks COVID-19 An infection – and Vaccination – to a Debilitating Coronary heart Situation
Smidt Coronary heart Institute researchers present the chance of creating postural orthostatic tachycardia syndrome, or POTS, is 5 instances increased after Cedars-Sinai has published research in the journal Nature Cardiovascular Research that confirms a connection between Postural Orthostatic Tachycardia Syndrome (POTS) and both COVID-19 and COVID-19 vaccination.
The study suggests that a small proportion of individuals who have been vaccinated against COVID-19 may develop POTS, which is a debilitating heart condition characterized by an abnormal increase in heart rate upon standing. Furthermore, their findings indicate that people diagnosed with COVID-19 are five times more likely to develop POTS after contracting the virus than after vaccination, emphasizing the importance of receiving the vaccine.
“The main message here is that while we see a potential link between COVID-19 vaccination and POTS, preventing COVID-19 through vaccination is still the best way to reduce your risk of developing POTS,” said Alan C. Kwan, MD, first and corresponding author of the study and a cardiovascular specialist at Cedars-Sinai.
Postural orthostatic tachycardia syndrome is a nervous system-related condition that most commonly affects young women of childbearing age. The most identifiable POTS symptom is a rapid increase in the heartbeat of more than 30 beats per minute or a heart rate that exceeds 120 beats per minute, within 10 minutes of standing.
Other symptoms include fainting, dizziness, and fatigue, although some patients with severe disease may also experience migraine, increased urination, sweaty extremities, anxiety, and tremor.
To validate their findings, the study authors used data from 284,592 vaccinated patients treated within the broader Cedars-Sinai Health System between the years 2020 and 2022, as well as 12,460 Cedars-Sinai patients with COVID-19.
“From this analysis, we found that the odds of developing POTS are higher 90 days after vaccine exposure than the 90 days prior to exposure,” said Kwan. “We also found that the relative odds of POTS were higher than would be explained by increases in visits to physicians after vaccination or infection.”
Kwan emphasizes that despite this finding, the rates of POTS after vaccination were much lower than rates of new POTS diagnosis after COVID-19.
“This knowledge identifies a possible—yet still relatively slim—association between COVID-19 vaccination and POTS,” said Kwan.
Many patients—especially those who developed POTS prior to the COVID-19 pandemic—spent years trying to get properly diagnosed. This is because many healthcare providers are unfamiliar with the disease and its symptoms, which often can be incorrectly attributed to chronic fatigue syndrome or other conditions. However, COVID-19 has expanded the medical field’s understanding of POTS.
“In an unexpected but important way, the COVID-19 pandemic brought a great deal of awareness to POTS—both to patients and providers,” said Peng-Sheng Chen, MD, an expert on the condition who leads one of only a few POTS specialty clinics in the nation. “Given a broader understanding of the disease, many patients can be diagnosed more quickly permitting earlier interventions that can greatly improve their symptoms.”
Many effective interventions involve lifestyle modifications, Chen says, including avoiding triggers such as prolonged standing, extreme heat, extreme cold, and alcoholic beverages. Additional recommended measures may include eating a high-sodium diet and wearing abdominal or lower-body compression garments. Certain medical therapies can also be considered.
Patients treated for POTS at the Smidt Heart Institute often are encouraged to join the cardiac rehabilitation program, which aims to strengthen the body and heart.
While the Nature Cardiovascular Research study sheds important light on vaccinations and POTS, researchers say it has its limitations. The hope, however, is this new knowledge will help improve conversations around COVID-19 and vaccines.
“We recognize as clinicians that side effects from vaccines can vary in type and severity, even if still uncommon overall. We hope that clearer data and improved understanding will eventually enhance medical trust and quality of care as well as communications around vaccines,” said Kwan. “Ultimately, our goal is to optimize vaccine uptake.”
