My cousin that died two years ago at 60 was very healthy and biked to work 10 miles per day... Suddenly collapsed with a heart attack...
They contributed it to him using his asthma inhaler his whole life and it is hard on your heart, that's why I try to lean toward using my nebulizer at home whenever I can instead of the inhaler...
However, I'm nowhere close to using an inhaler for 45 or more years like he did, so I have lots of time before the inhaler takes me out... I just started with the asthma inhaler last year, but it doesn't hurt to be as careful as you can...
