ECG at follow-up visits will only be obtained when clinically indicated, such as recurrent chest pain, ischemia, or significant arrhythmias, heart failure or other signs or symptoms of clinical instability. cRoutine follow-up angiography will be recommended at 9 months, but it can be performed at 9 ± 2 --> 9 ± 3 months. Unscheduled angiograms ≥6 months after the index procedure will be considered as the 9-month follow-up angiogram in final analysis. dMeasurement may be made later, before discharge, when the patient is in a fasting state. eFor patients with diagnosed diabetes mellitus. fCardiac enzymes should be followed up for at least 24 hours in patients indicated clinically, such as recurrent chest pain, ischemia, or significant arrhythmias, heart failure or other signs or symptoms of clinical instability. Otherwise the decision is up to the operator. If follow-up is made, enzymes must be followed every 8 hours for at least 24 hours post index procedure.
