Well I have one narrow artery, but it was borderline to get a stent, and due to my age they left me and monitored me closely, that was 9 years ago, and I no longer see the specialist every 6 months, my physiological health is as it is, having had a heart attack part of the heart that was starved of oxygen dies, it won't repair itself, it is what it is.
As for drugs I am on, aspirin to thin my blood a bit, valsartan to help keep blood pressure low, but I have never had high blood pressure anyway, even during the heart attack my blood pressure was fine, I am also on a statin for cholesterol but again that has always been fine, and lastly I am on some meds to help stop heart burn (acid reflux) that the other meds cause.
