According to a US cross-sectional study, every fifth hospital patient with a respiratory syncytial virus (RSV) infection develops an acute cardiovascular event. For patients with a preexisting cardiovascular condition, an acute cardiovascular event occurs in every third patient, as shown by data published in JAMA Internal Medicine.
RSV attacks the respiratory tract, especially the mucous membranes of the upper airways and the ciliated epithelium of the trachea and bronchi. It is not the first respiratory virus with devastating consequences for the cardiovascular system.
“In the COVID-19 pandemic, we painfully learned that patients with preexisting cardiovascular conditions have significantly higher mortality rates and that cardiovascular causes are essential in COVID-19 mortality,” said Stephan Baldus, MD, director of Clinic III for Internal Medicine at the Heart Center of the University Hospital Cologne in Cologne, Germany.
“A direct link between the virus and the development of acute coronary events has also been demonstrated for influenza. Studies have shown that in the early days of an influenza infection, the rates of heart attacks and subsequent deaths increase significantly,” Dr. Baldus added. “And now, this study shows that patients with cardiovascular diseases have a critically increased risk for an acute cardiovascular event during an RSV infection.”
RSV Surveillance
Rebecca C. Woodruff, PhD, of the Centers for Disease Control and Prevention in Atlanta, and her colleagues analyzed data from an RSV surveillance program involving hospitals in 12 US states. The data covered hospitalized adults aged 50 years and older from five RSV seasons (from 2014/2015 to 2017/2018 and 2022/2023).
The 6248 patients were hospitalized for various reasons. They had a mean age of 73 years, and 60% of them were women. RSV infection was detected through a physician-ordered test within 14 days of admission. Slightly more than half (56.4%) of the patients had a preexisting cardiovascular condition that did not necessitate hospital treatment.
The researchers reported that more than a fifth (22.4%) of the patients with RSV had an acute cardiovascular event. Acute heart failure was most common (15.8%), but there were also acute ischemic heart disease in 7.5%, hypertensive crisis in 1.3%, ventricular tachycardia in 1.1%, and cardiogenic shock in 0.6%.
Acute Cardiovascular Events
Among the study population, 8.5% had no documented cardiovascular preexisting conditions. However, the risk was particularly elevated in patients with cardiovascular preexisting conditions. Overall, 33.0% of them had an acute cardiovascular event during the RSV infection.
Patients with acute cardiovascular events were almost twice as likely to have a severe course as those without acute cardiovascular events. The researchers considered treatment in the intensive care unit, the need for invasive mechanical ventilation, or the patient’s death in the hospital as severe outcomes.
Of all hospitalized patients with RSV, 18.6% required intensive care unit treatment, and 4.9% died during hospitalization. Compared with those without acute cardiovascular events, those with acute cardiovascular events had a significantly higher risk for intensive care treatment (25.8% vs 16.5%) and death in the hospital (8.1% vs 4.0%).
Although the analysis is not a prospective controlled study, according to Dr. Baldus, the results strongly suggest that RSV has cardiovascular effects. “When one in five hospitalized patients develops a cardiovascular event, that’s very suggestive,” he said.
More Testing Needed?
The results add to the evidence that RSV infections in older patients are associated with considerable morbidity and mortality. Unlike for COVID-19 and influenza, however, there is hardly any surveillance for RSV infections. RSV testing in hospitals is rare. Many doctors opt against testing for RSV because they are not aware of the importance of RSV as a pathogen in adults, but also because the diagnosis of RSV has no therapeutic consequences, wrote Dr. Woodruff and her colleagues.
Because there is no targeted therapy for an RSV infection, the detection of RSV can only be used as a marker for a risk for the development of an acute cardiovascular event, according to Dr. Baldus. Even considering the new study data, he emphasized, “Not every patient with a cardiovascular preexisting condition needs to be tested for RSV.”
The crucial factor is the clinical presentation. “If there is a clinical indication of pulmonary impairment (shortness of breath, tachypnea, subfebrile temperatures, or a diminished general condition) it would be desirable to perform an RSV test. This is especially true for patients requiring intensive care who need respiratory support,” said Dr. Baldus.
Benefits of Vaccination
The results highlight the basic epidemiology of potential cardiovascular complications of RSV infections, but before RSV vaccination became available, wrote Dr. Woodruff and her colleagues.
In 2023, the first RSV vaccine for adults aged 60 years and older was approved. “Here, a door to additional possibilities opens,” said Dr. Baldus. Although there are currently no official vaccination recommendations from Germany’s Standing Vaccination Commission, medical societies of oncologists and pulmonologists recommend vaccination against RSV. “Given the relevance of cardiovascular diseases for the prognosis of patients, but also for the occurrence of an acute cardiovascular event upon detection of RSV, the corresponding recommendation is expected to come,” said Dr. Baldus.
