Stenting is a relatively safe procedure. Once implanted than stent remain part of body forever. However in normal stents there is a chance of restenosis in first 6 months (depending upon length of lesions etc ranging from 8 - 60%). If the heart is totally revascularised than whatever heart muscle has to regain gains in first 3-6 months time. He should be evaluated for EF by 2D Echo Doppler. Risk to life in later recovery of heart attack may be due to arrhythmia in low ejection fraction cases. He should control his risk factors optimally and should follow a stress free life style. He should also get evaluated again at 6 months time (with stress test etc) even if he is asymptomatic.
