This study determined the long-term effect of moderate renal insufficiency on death and major adverse cardiac events （MACE） after stent based PCI and examined whether drug-eluting stent implantation could favourably influence clinical outcome. Methods Major adverse cardiac events and causes of mortality were determined for 1012 patients undergoing percutaneous intervention from January 1, 2002 to December 31, 2004 at Shanghai Ruijin Hospital. Based on estimated creatinine clearance levels, long term outcomes were compared between patients with estimated creatinine clearance 〈60 ml/min （renal insufficiency group; n=410） and those with estimated creatinine clearance ≥60 ml/min （control group; n=602）. Subgroup analysis was also made for patients with renal insufficiency between drug eluting stent （n=264） and bare metal stent implantation （n=146） during PCI. Results During follow-up （average 17 months） after successful PCI, all causes of death （7.1% vs 2.3%, P〈0.01） and cardiac death （3.4% vs 1.0%, all P〈0.01） were significantly higher in renal insufficiency group than in control group. For patients with moderate renal insufficiency, drug-eluting stent implantation reduced significantly all causes of death （5.3% vs 10.9%, P〈0.05） and occurrence of major cardiac adverse events （15.1% vs 24.6%, P〈0.05） compared with bare metal stents. Conclusions Moderate renal insufficiency is an important clinical factor influencing the mortality after PCI in patients with coronary artery disease and the use of drug-eluting stents should be the preferred therapy for the improvement of long-term outcomes in such patients.展开更多

Methods: In this prospective, non-randomized observational study we identified patients who had undergone either stand-alone XEN<sup>®</sup> implantation (XEN solo) or XEN<sup>®</sup> implantation in combination with phacoemulsification (XEN combi). All patients who had undergone an implantation during the period 01.04.17-31.10.19 at the Department of Ophthalmology, Drammen Hospital, Norway, were asked to participate. Success was defined as IOP between 5 - 18 mmHg and 20% pressure reduction without medications. Qualified success required the same pressure interval and reduction but allowed medications. The procedure was deemed as failure if pressure requirements were not met, vision was reduced to light perception or worse, or if there was a converion to secondary glaucoma surgery. Results: Out of 115 patients and 133 eyes identified, 87 patients and 99 eyes consented to participate. All patients were Caucasians with a mean age of 73.6 years. The study had a mean (range) follow-up of 38.9 (28 - 54) months. The mean medicated baseline (SD) was reduced from 22.6 (7.9) mmHg on 3.2 (1.1) medications to 14.2 (5.6) mmHg on 1.4 (1.6) medications. Success and qualified success were achieved in 22.2% and 21.2%, respectively. Needling was performed in 34 eyes. Conclusion: XEN<sup>®</sup> 45 gel stent implantation is a safe procedure, offering a significantly lower IOP and number of medications in a subset of patients with open angle glaucoma.展开更多
