cody,
Thanks for the post.
The simple answer is yes, a successful angioplasty can last forever. There is always risk of progression of the coronary disease even in areas that werent stented. However, in the absence of any changes in your stress testing or the presence of symptoms, I wouldnt try to change the imaging techniques or worry too much about the stent.
We know that statins and lifestyle modifications can have significant impact to slow or even halt the progression of coronary disease.
Continue everything you are doing, it has great impact on why youve done so well this far.
good luck
Keep it UP - Good Job..
