Yes, but by what percentage? Does it match up to the actual deaths? The answer is no, it does not. Also you can look at historical data from when we had summers that were 100F average temperatures and find that heart attacks did not rise by the percentages we are seeing now.
Also when people die of heart attacks now, they are pulling massive blood clots out the size of fists that look like trees (branching veins and arteries). Please explain in more detail.
