I had a heart attack a few years ago while on chemo. I take a baby aspirin a day and blood pressure med. It helps but I’m pretty much resigned to my fate. One thing that aggravates chest pain is caffeine. It’s best to stay off it. I like that tip about unlocking the front door and waiting for the 9/11 response. IF you CAN get to the front door, that is.
I also take a baby aspirin a day and closely monitor my BP. We do not have a history of heart disease, but my mom did have a stroke, so I’m not taking any chances.
