Viral Infections Dramatically Increase Cardiovascular Risks in Older Adults, Study Shows

A meta-study highlights how viral infections like flu and COVID-19 significantly elevate heart attack and stroke risks in older adults, urging vaccination for prevention.

    Key details

  • • A meta-study finds flu infection increases stroke risk fivefold and heart attack risk fourfold within four weeks.
  • • COVID-19 raises heart attack risk by 3.1 times and stroke risk by 2.9 times compared to uninfected people.
  • • Viral immune responses cause inflammation, blood clotting, and vessel damage, intensifying risks in older adults.
  • • Vaccinations are vital as they prevent infections and reduce cardiovascular strain, especially for seniors over 60.

Recent research reveals a significant rise in the risk of heart attacks and strokes following viral infections such as influenza and COVID-19, particularly among older adults. A meta-study conducted by the University of California in Los Angeles shows that within four weeks of contracting the flu, the risk of stroke increases fivefold and the risk of heart attack quadruples. Similarly, those infected with COVID-19 face a 3.1 times higher risk of heart attacks and a 2.9 times higher risk of strokes compared to uninfected individuals.

These increased risks are linked to the body's immune response to viral infections, which produces inflammatory substances that can cause blood clotting and damage to blood vessels. This effect is especially concerning for older individuals whose blood vessels naturally lose elasticity with age. Beyond influenza and COVID-19, other viruses such as HIV, hepatitis, and shingles also raise cardiovascular risks.

Health authorities emphasize vaccination as a critical preventive measure. Vaccinations not only prevent infection but also reduce the cardiovascular strain on the body. Seniors over the age of 60 are encouraged to take advantage of free vaccinations against flu, COVID-19, and shingles to mitigate the chance of severe health events and hospitalizations.

Overall, this research highlights the crucial need for older adults to protect their heart health through regular vaccinations and maintaining healthy lifestyle choices, given the substantial cardiovascular threat posed by viral infections.
