چکیده انگلیسی
The difference in the intraluminal intensity of blood speckle (IBS) on integrated backscatter-intravascular ultrasound (IB-IVUS) across a coronary artery stenosis (i.e., ÎIBS) has previously shown a negative correlation with fractional flow reserve, reflecting an impaired coronary blood flow. Periprocedural myocardial injury (PMI) after coronary stenting has also been associated with coronary circulatory dysfunction. The aim of this study was to investigate the relation between ÎIBS after coronary stenting and PMI. A total of 180 patients who underwent elective coronary stenting under IVUS guidance for a single lesion were included. Intraluminal IBS was measured using IB-IVUS in cross sections at the ostium of the target vessel and at the distal reference of the stent. ÎIBS was calculated as (distal IBS value)âââ(ostium IBS value). PMI was defined as an elevation of troponin I >5 times the 99th percentile upper reference limit (>0.45âng/ml) within 24 hours after the procedure. The mean ÎIBS after coronary stenting was 6.52â±â5.71. There was a significantly greater use of the rotational atherectomy, the number of stents, the total stent length, and ÎIBS in patients with PMI than those without. In the receiver operating characteristic curve analysis, ÎIBS significantly predicted PMI (area under the curve 0.64, best cut-off value 7.88, pâ=â0.001). Multiple logistic regression analysis determined that the total stent length, the use of rotational atherectomy, and ÎIBS were independent predictors of PMI. In conclusion, greater ÎIBS assessed by IB-IVUS was significantly associated with PMI after coronary stenting in patients with a stable coronary artery disease.
