Understanding the risks of winter viruses
As the winter months roll in, a surge of respiratory viruses like RSV, influenza, COVID-19, and norovirus are making headlines. These viruses are not just causing sniffles and coughs; they can also pose serious risks to heart health.
According to the American Heart Association (AHA), certain viral infections can increase the risk of heart attacks and strokes, particularly within the first three days of infection. This heightened risk can persist for up to 90 days, making it essential for everyone, especially those with pre-existing heart conditions, to stay vigilant.
Symptoms to watch for
Many people may mistake the symptoms of these winter viruses for typical cold or flu symptoms. However, signs like shortness of breath, wheezing, and palpitations could indicate something more serious, such as heart failure. Dr. Johanna Contreras, a cardiologist at Mount Sinai, emphasizes that patients often overlook these symptoms, assuming they are just dealing with a respiratory illness.
Symptoms like chest pain, dizziness, and extreme fatigue should not be ignored, as they could mask life-threatening conditions like pulmonary embolism or myocarditis.
The inflammatory response and heart health
When the body fights off a viral infection, it triggers an inflammatory response.
While this is a natural defense mechanism, it can inadvertently harm cardiac tissue, especially in individuals with existing heart issues. Dr. Icilma Fergus notes that the immune response can exacerbate conditions like atrial fibrillation or coronary heart disease. Therefore, anyone with a known heart condition should be particularly cautious during this virus-heavy season.
It’s crucial to discuss any post-viral symptoms with a healthcare professional, especially if they persist after recovering from a cold or flu.
Precautions to take this winter
To minimize the risk of contracting winter viruses, the AHA recommends several precautions.
Staying updated on vaccinations, practicing good hygiene, and avoiding close contact with sick individuals can significantly reduce your chances of getting infected. If you do fall ill, it’s vital to monitor your symptoms closely and seek medical attention if you experience chest pain, difficulty breathing, or severe fatigue. Remember, early intervention can make a significant difference in outcomes, especially for those at higher risk.
