I am 63, I have multiple blockages more than double what you have, and I also know what it is like to wonder whether my next "event" might prove to be my last by ending in a fatal heart attack. However, this past month on a completely-oil-free and plant-based-only diet with no meat or dairy of any kind at all has begun convincing me that my own condition can be reversed without having to use bypass surgery or even stents to merely "manage the disease" while it is actually being treated via diet and certain supplements related to endothelial function. I do not want to break any rules here by posting links or appearing to solicit for anyone or promote anything, so I will just suggest a web search for "coronary diet" such as where I began.
