BACKGROUND:Impact of plaque composition on late stent malapposition (LSM) after drug-eluting stent (DES) implantation has not been evaluated.
METHODS:We evaluated the relation between plaque components at poststenting peristent area (between external elastic membrane and stent areas) and LSM after DES implantation in 266 patients (314 native lesions; paclitaxel-eluting stent in 205 lesions, sirolimus-eluting stent in 66 lesions, zotarolimus-eluting stent in 32 lesions and everolimus-eluting stent in 11 lesions) in whom virtual-histology intravascular ultrasound was performed at index (poststenting) and follow-up (mean: 11.7 ± 4.8 months).
RESULTS:LSM occurred in 24 patients with 30 lesions (9.6%) and there were no significant differences in the incidences of LSM among 4 DES groups [21/205 (10.2%) in paclitaxel-eluting stent, 6/66 (9.1%) in sirolimus-eluting stent, 2/32 (6.3%) in zotarolimus-eluting stent and 1/11 (9.1%) in everolimus-eluting stent, p=0.5)]. Patients with LSM were presented with more acute myocardial infarction (50% vs. 28%, p=0.026) and were more diabetics (50% vs. 30%, p=0.030) compared with those without LSM. Lesions with LSM had more poststenting peristent %necrotic core (NC) volume compared with those without LSM (25.8 ± 11.1% vs. 21.0 ± 5.7%, p<0.001). Independent predictors of LSM were poststenting peristent %NC volume [odds ratio (OR); 1.216, 95% CI; 1.053-1.405, p=0.008], acute myocardial infarction (OR; 2.897, 95% CI; 1.675-4.118, p=0.029), and diabetes mellitus (OR; 2.413, 95% CI; 1.543-3.996, p=0.038).
CONCLUSIONS: Poststenting peristent NC component especially in patients with acute myocardial infarction and in
