As one with several stents, use this experience as a warning.
I don't want to sound preachy, but if over 40, get a stress test. If you have a bad family history, get one at 35. If you're overweight, lose the weight. If your BP is high, exercise, drop weight, eat better and get the right meds to lower it. Same with cholesterol.
If you have sleep issues, sleep apnea can be a HUGE issue for heart disease. Do a sleep study and if you have apnea, get the CPAP mask.
It's hard to change habits until forced to, but taking the right steps isn't rocket science.
Then, if like me and you have issue's, make sure to stay up to date on checkups.
Good luck and stay healthy!
