If they were obstructive, you would already need bypass surgery.
With aggressive medical management and lifestyle change you may get away with a stent or 2 later down the road...
Most likely though they’ll have to break your chest open at some point. It’s pretty serious. I’d make as many lifestyle changes and comply with instructions are carefully as possible. Stay in frequent communication with your doctor and don’t ignore chest pain. It’s pretty serious.
It’s perfectly ok to be stressed in this scenario.
I would recommend that you actually seek out a therapist or behavioral health professional to see as well. Stress can make the problem worse and they can often help you come to terms with what you’re going through
All sorts of people, myself included, see such counselors just to get some advice about life issues (ie to cope with the stress of working in cardiac catheterization or electrophysiology all day).
I would also recommend that you use that stress.. channel it in to becoming this biggest health nut the world has ever seen.
Often times these sorts of “wake up calls” are just what an individual needs to look back at some of their past medical decisions (drinking, smoking, diet etc) and realize the error of their ways a bit.
This may or may not be you. A big factor here is genetics and lots of patients with healthy lifestyles find themselves in the same boat.
This all said; you really do need to take this seriously. Yes. You can die from this. You can get a bypass surgery as a result of this.
If you like being alive, you will make your health and compliance with any and all instructions a priority.
If you take the medicines and do the absolute best you can to lead to healthiest lifestyle possible I think you got a good chance moving forward!
