If you spend time on social media, you may have seen the hashtag #DiedSuddenly. It’s often tied to the idea that people are dying off in large numbers because they received the COVID-19 vaccine. Various experts say this is not true. However, they are on to something that is true. There has been an increase in younger people having heart attacks, a trend that started before 2020 and then sped up during the pandemic. A study last year by Cedars-Sinai Medical Center in Los Angeles shows heart attack deaths were up for all age groups in 2020 and 2021. But the largest increase was in the 25-44 age group, a 29% jump during those years. It’s something doctors are now starting to better understand.
