The importance of regular immunizations for heart health

While most parents are good at keeping track of vaccines their kids need to stay healthy, many adults don’t realize there are immunizations important for keeping themselves heart-healthy, as well.

Adults, especially those with a history of heart disease or stroke, should take steps to stay up-to-date on preventive vaccines, particularly for the flu and COVID-19.

Influenza – While many experience just a few days of aches and chills, the flu can be deadly for some, including young children, the elderly and those with chronic conditions like heart disease, stroke and diabetes. There has also been research linking flu infection to cardiovascular disease (CVD). Getting a flu shot can not only prevent the flu, it may also reduce the risk of having a heart attack or stroke.

In fact, a study published in “Stroke” found that, among a group of people hospitalized for various reasons, those who experienced a flu-like illness within a month of their hospitalization were 38% more likely to have a stroke. Receiving the flu vaccine within a year prior to hospitalization lowered a person’s stroke risk to 11%.

A study from the registry published in “Circulation: Arrhythmia and Electrophysiology” found new-onset atrial fibrillation in 1 in 20 patients hospitalized with COVID-19.

The pneumococcal vaccination protects against a common cause of severe pneumonia and is especially important for people 65 and older, and others with certain underlying medical conditions. This type of pneumonia can be deadly, especially for people already at high risk for health complications, including CVD.

Shingles, a viral infection caused by the chickenpox virus, has been linked to an increased risk of stroke. More than 99% of people age 40 or older in the United States may carry the dormant chickenpox virus, also known as the varicella-zoster virus, and not even realize it.
