Speaking from my own experience, I think this has a lot to do with most heart attacks not requiring hospitalization at all. I was fine. Shaky and weak but mending myself just fine. When you have a heart attack there is an elevation of an enzyme called troponin, and upon finding it in your blood, you are swept from the ER to wherever cardiologists can assess whether you need a stent or a bypass or whatever. If you're not on your ass, you don't really need anything. Your body will rebuild a blood supply around a blocked artery by itself and stents are not proving to be improving outcomes for heart disease patients. They're pretty much only improving the sense of helplessness for doctors and patients.
In other words: there are a lot of not really that necessary hospitalizations being interrupted by coronavirus.

What I'm trying to say is that there aren't any fewer heart attacks, just fewer of them going to hospital beds.
pipe up any time....
