This paper was designed to determine vascular restoration in HBR patients by coronary angioscopy and optical coherence tomography. We prospectively reviewed 38 HBR patients with coronary artery disease who underwent coronary artery disease treatment by everolimus-eluting stent implantation or drug-coated stent implantation. According to CAS results, mean yellow color grade was significantly higher with EES than with DCS. The frequency of uncovered struts was much lower with EES than with DCS, but malapposed struts were significantly higher with EES than with DCS, although the frequency of struts was significantly higher with EES than with DCS.

Myocardial infarction culprit lesions in ST-segment elevation myocardial infarction culprit lesions are uncertain, especially in myocardial infarction culprit lesions. In STEMI patients, durable polymer-coated everolimus-eluting stents and BP-EES were compared early and mid-term arterial recovery. The mean percentage of covered struts on FD-OCT 2 weeks post-PCI was the primary endpoint of this research. 84% in BP-EES and 72. 3 percent in DP-EES, respectively, with the lower end of one-sided 95% confidence interval u2212 5. 6; P _non-inferiority = 0. 0756] The primary endpoint of %covered struts at 2 weeks was 74% and 73% in DP-EES [risk difference u2212 5. 6] has been 0. 04 percent, lower limit of one-sided 94%, u2212 5. 7; P u2203212 u2212 BP-EES had a significantly higher average neointimal area with a significantly lower average intra-stent tissue unevenness score than DP-EES at 12 months, indicating more uniform neointimal coverage with BP-EES at 12 months. The significantly improved arterial recovery with BP-EES at 12 months provides a more realistic picture of STEMI culprit lesions.
