(Press-News.org) Amsterdam, Netherlands – 27 Aug 2023: Intravascular imaging-guided percutaneous coronary intervention (PCI) is associated with a lower rate of target lesion failure compared with angiography-guided PCI, according to late breaking research presented in a Hot Line session today at ESC Congress 2023.1
Numerous randomised trials have compared intravascular imaging-guided PCI with angiography-guided PCI. However, most of these prior trials have used intravascular ultrasound (IVUS). Optical coherence tomography (OCT) is a newer intravascular imaging modality that has enhanced resolution compared to IVUS. During Hot Line session 4 at ESC Congress 2023, two randomised trials of OCT-guided versus angiography-guided PCI will be presented for the first time, the ILUMIEN IV trial in high-risk patients with complex lesions and the OCTOBER trial in bifurcation lesions.
The authors of the current study performed a real-time updated network meta-analysis, integrating data from the ILUMIEN IV and OCTOBER trials with prior studies, to examine the effects of intravascular imaging guidance versus angiography guidance. The analysis compared: 1) the overall effects of intravascular imaging (IVUS and OCT) in improving outcomes of the PCI procedure versus angiography; 2) IVUS versus angiography; 3) OCT versus angiography; and 4) IVUS versus OCT.
The analysis incorporated 20 randomised trials of intravascular imaging-guided PCI compared with angiography-guided PCI in 12,428 patients with chronic and acute coronary syndromes. Of those, 7,038 were randomly allocated to intravascular imaging guidance (including 3,120 patients randomised to IVUS guidance, 2,826 patients randomised to OCT guidance, and 1,092 patients randomised to IVUS or OCT guidance), and 5,390 patients were randomly allocated to angiography guidance. Patients were followed for between 6 months and 5 years.
The primary endpoint was target lesion failure, defined as a composite of cardiac death, target vessel myocardial infarction, or target lesion revascularisation. Secondary endpoints included cardiac death, target vessel myocardial infarction, target lesion revascularisation, and stent thrombosis, as well as all-cause death, all myocardial infarction and target vessel revascularisation.
Intravascular imaging (IVUS or OCT) guidance of PCI resulted in reductions in the primary composite outcome of target lesion failure by 31% compared with angiography guidance of PCI. Regarding secondary outcomes, intravascular imaging guidance of PCI resulted in reductions in cardiac death by 46%, target vessel myocardial infarction by 20%, target lesion revascularisation by 29%, and stent thrombosis by 52% compared with angiography guidance of PCI. There were also statistically significant reductions in all-cause death, all myocardial infarction and target vessel revascularisation with intravascular imaging guidance of PCI. The outcomes were similar for OCT-guided PCI and IVUS-guided PCI when compared individually against angiography and when compared to each other.
Principal investigator Dr. Gregg Stone of Icahn School of Medicine at Mount Sinai, New York, US said: “The results of this network meta-analysis emphasise the importance of physicians using intravascular imaging with either OCT or IVUS to optimise stent outcomes and improve the long-term prognosis of their patients.”

Pulsed field ablation is noninferior to thermal ablation in paroxysmal atrial fibrillation
2023-08-28
Amsterdam, Netherlands – 27 Aug 2023: Pulsed field ablation (PFA) is as effective and safe as conventional thermal ablation for the treatment of paroxysmal atrial fibrillation (AF), according to late breaking research presented in a Hot Line session today at ESC Congress 2023.1
ESC guidelines recommend catheter ablation after failure of drug therapy in patients with paroxysmal AF.2 Conventional ablation technology uses thermal energy (either heat/radiofrequency energy or cold/cryothermal energy) to ablate the tissue. Unlike thermal ablation, PFA uses high energy electrical pulses to destroy tissue by a process called electroporation. Preclinical ...

Still separate and unequal: How subsidized housing exacerbates inequality
2023-08-28
For years, scholars, advocates and journalists have highlighted the ongoing racism and segregation in the housing market, yet a segment of the housing market — government-subsidized housing — has been overlooked, until now.
A new study from researchers at Washington University in St. Louis and other institutions is the first in decades to investigate racial inequality in the subsidized housing market. Using restricted 2017 American Housing Survey data provided by the U.S. Department ...

Amsterdam, Netherlands – 27 Aug 2023: A randomised trial involving all hospitals in London, UK, has found no difference in survival at 30 days in patients with resuscitated cardiac arrest in the community who were taken by ambulance to a cardiac arrest centre compared with those delivered to the geographically closest emergency department. That’s the finding of late breaking research presented in a Hot Line session today at ESC Congress 2023.1 The study also found no overall difference in neurological outcomes at discharge and at three months between groups.

Which radio waves disrupt the magnetic sense in migratory birds?
2023-08-28
While radio waves emitted by radio and television broadcasting and CB radio can disrupt the magnetic compass of migratory birds, those used in mobile communication networks do not because the frequencies are too high to affect their sense of orientation. This was the key finding of a new study published in the scientific journal Proceedings of the National Academy of Sciences (PNAS) by a team of researchers led by Professor Dr Henrik Mouritsen of the University of Oldenburg and Professor Dr Peter Hore of the University of Oxford (UK).
This finding also bolsters the researchers' theory that the magnetic compass sense in these birds is based on a quantum-mechanical ...
