Hypothesis
Does the single bare metal stent (BMS) have similar efficacy and safety compared to the single drug eluting stent (DES) in nondiabetic patients with a simple de novo lesion in the middle and large vessel?
Conclusion
The single BMS has similar efficacy and safety to single DES in nondiabetic patients with a simple de novo lesion in the middle and large vessel at short- and long-term follow-up.
Supporting Evidence
- BMS group had lower hypercholesteremia rate (22.0% vs 38.8%) than DES group.
- Both groups had similar stent length and diameter after the procedure.
- No significant differences in TLR and Re-MI rates between the two groups at 1- and 3-year follow-up.
Takeaway
This study looked at two types of heart stents and found that one type is just as good as the other for patients without diabetes.
Methodology
Two hundred and thirty-five consecutive patients were treated with BMS or DES and followed up for outcomes at 6 months, 1 year, and 3 years.
Potential Biases
The BMS group had a lower hypercholesteremia rate than the DES group, which may introduce bias.
Limitations
The study was not a randomized controlled trial and had a small population from a single medical center.
Participant Demographics
Nondiabetic patients with a simple de novo lesion in the middle and large vessel.
