I haven't found the numbers behind this. It's from https://www.cedars-sinai.org/newsroom/covid-19-surges-linked-to-spike-in-heart-attacks/ . I find the article but not the raw numbers, so I can't give you that, other than "In the year before the pandemic, there were 143,787 heart attack deaths; within the first year of the pandemic, this number had increased by 14% to 164,096." But I don't have the breakdown based on age.
