I admit that I didn’t dive deep into the appendices; but the summary seemed practically deliberate in not providing the information you’d need to say whether this is a good thing or not.
Specifically, it looked at mortality from one source or the other, among various demographics; but I couldn’t find anything on age-at-time-of-death, which is what you’d really want to know in order to distinguish between the more or less positive “Heart disease is substantially preventable and has some decent treatment options, and we’ve finally seen that paying off” and the much less happy “we are seeing a lot of cancers killing people before heart disease has a chance to”.
Off the cuff, I’d assume that it’s mostly the former(though if you live in a location referred to as ‘cancer alley’ your mileage may vary); but the data as presented were less than helpful in trying to determine one way or the other.
