Hi Janice:
Bare-metal (BM) or drug-eluting stents (DES)
lasts in the coronary artery for the life of the patient. After initially implanted, the stent is gradually incorporated (new tissue grows over and through the struts, drug-eluting somewhat delays this, hence possible blood clot problems) into the vessel wall, essentially becoming a permanent part of it.
The drug contained on a DES, which is gradually released, and the polymer coating that gradually releases it, only lasts for a limited period of time, as is designed to, is intended to do so.
SOMETIMES THOUGH, a problem can occur at the stented site, such as restenosis (renarrowing, in some cases, even with DES), or new or accelerated atherosclerotic plaque buildup, requiring another angioplasty and possible re-stenting or "stent sandwich" (placing a stent within a stent).
The bottom
lineCoronary stents are just a Band-aid or spot treatment, as this
does not address the underlying disease process and what drives the progression.
Most important, coronary artery disease (CAD) is a
lifelong unpredictable (can exhibit periods of stabilization, acceleration, and even some regression)
condition, requiring a continuum of care, as well as good doctor-patient/patient-doctor communication and understanding at
ALL times.
Best of luck to your brother down the road of life.
Take care,

Good to know, for the primary and secondary prevention of heart attack and brain attack/stroke
Epidemiologic studies (EDS) have revealed risk factors for atherosclerosis (typically affecting the coronary, carotid, and peripheral arteries), which includes age, gender, genetics (gene deletion, malfunction, or mutation), diabetes (considered as being the highest risk factor), smoking (includes secondhand), inactivity, obesity (a global epidemic, "globesity") high blood pressure (hypertension), diet high in fat, saturated fat and cholesterol, high LDL, high Lp(a), high ApoB, high Lp-PLA2, high triglycerides, LOW HDL (less than 40 mg/dL, an HDL level of 60/65 mg/dL or more is considered protective against coronary artery disease), high homocysteine, and high C-reactive protein (CRP/hs-CRP).
