Some winter viruses could trigger heart complications, experts warn

As health officials report a surge of winter viruses, health experts are warning that heart disease symptoms can sometimes mimic respiratory illnesses. The U.S. is currently facing a concerning situation with four viruses circulating, including respiratory syncytial virus (RSV), influenza, COVID-19, and norovirus, leading to fears of a possible “quademic.”
The American Heart Association (AHA) has confirmed that certain viruses have been linked to an increased risk of heart attack and stroke. According to the AHA, the highest risk of heart-related complications is within three days of infection but can remain heightened for up to 90 days.
Dr. Johanna Contreras, a cardiologist at Mount Sinai Fuster Heart Hospital in New York City, has observed cases where patients mistake virus symptoms for serious heart issues. Symptoms such as shortness of breath, wheezing, coughing, swelling, and palpitations could be signs of heart failure rather than a common cold.
Other symptoms like weakness, fever, dizziness, and chest pain could also mask potentially life-threatening conditions such as pulmonary embolism, heart attack, pericarditis, heart failure, or viral myocarditis. It is crucial for individuals to be aware of these possibilities and seek medical attention if they experience such symptoms.
Viruses can trigger an inflammatory response in the body, which can exacerbate cardiac conditions. Dr. Icilma Fergus, director of cardiovascular disparities at the Mount Sinai Health System, explains that viruses that promote a hypercoagulable state are particularly dangerous and can lead to complications like atrial fibrillation, coronary heart disease, or heart failure.
Dr. Anuradha Lala, another cardiologist at Mount Sinai, emphasizes that individuals with pre-existing heart conditions are at higher risk of experiencing exacerbations due to viral infections. The body’s immune response to fighting off viruses can inadvertently harm cardiac tissue, leading to complications.
It is important for individuals to pay attention to post-virus symptoms, especially if they are in high-risk groups. Symptoms like persistent chest pain, palpitations, difficulty breathing, or swelling of the legs should not be ignored and should prompt a visit to a healthcare professional.
Preventive measures such as frequent handwashing, avoiding close contact with sick individuals, staying home when experiencing symptoms, disinfecting surfaces, and covering coughs and sneezes can help reduce the risk of contracting winter illnesses. Vaccination for vulnerable groups is also recommended to protect against viruses.
As heart disease remains the leading cause of death in the U.S., it is crucial for individuals to be vigilant about their health, especially during the winter months when viruses are more prevalent. By following preventive measures and seeking medical attention when necessary, individuals can protect themselves from potential cardiac complications associated with winter viruses.
