6 %) experienced sudden death and 13 (3.0 %) required implantation of a pacemaker. On univariate analysis, adverse events were associated with advancing age, prolongation of the PR, QRS and corrected QT (QTc) intervals, as well as the degree of neuromuscular impairment. No such relationship was found with the extent of genetic anomaly (number of cytosine-thymine-guanine repeats). However, multivariate analysis using Cox proportional hazards models showed that only baseline PR and QTc
intervals were significantly linked to the LY3023414 nmr end points of sudden death or pacemaker implantation; the age-adjusted RR was 3.7 (95 % CI 1.5 to 8.6) if baseline PR was 200 ms or longer (P=0.003), and 3.0 (95 % CI 1.0 to 8.8) if selleck the baseline QTc was 450 ms or longer (P=0.047).CONCLUSIONS:
In a large unselected cohort of 428 patients with DM1, the cumulative incidence of sudden death was relatively low, and the delayed conduction on surface electrocardiogram was found to be potentially helpful for identifying patients at risk for sudden death or pacemaker implantation.”
“Background: A well-established method to preserve failing synthetic arteriovenous grafts
(AVGs) dialysis accesses is percutaneous transluminal angioplasty (PTA). Nevertheless, the one-year primary patency rate following PTA is approximately 25%. This study was designed to compare the angiographic and clinical outcomes following stent-graft insertion versus angioplasty and/or bare metal stenting (BMS) of recurrently failing AVGs, because of anastomotic and/or venous outflow stenoses.
Methods: Self-expanding stent-grafts were deployed for the treatment of failing AVGs in case of recurrent stenosis after treatment with conventional angioplasty or bail-out BMS. Regular angiographic follow-up was scheduled every two months the first six months and every three
months thereafter. Data from previous procedures on the same treatment site were retrieved from our database. Primary patency was defined as a functioning graft with a patent treatment site without angiographic restenosis >50% and without any subsequent repeat procedures. Outcome data were analyzed by Kaplan-Meier analysis.
Results: In total, 35 patients previously treated with angioplasty and/or BMS for the treatment Compound C concentration of recurrent significant AVG stenosis (group PTA), underwent stent-graft placement of the same treatment site (group SG). Of those, 20 patients had undergone angioplasty and 15 bail-out BMS. Mean lesion length was 4.8 +/- 1.7cm. Primary patency was significantly improved in the SG group (Hazard Ratio [HR] = 0.2 [95% CI= 0.11-0.36], P=.0001) by log-rank test. The estimated six and 12-month patency rates were 76.9% vs. 25.7%, and 61.4% vs. 8.6% for groups SG and PTA respectively, (P<.0001).
Conclusions: Stent-graft placement significantly improves primary patency of anastomotic and venous outflow stenoses in recurrently failing prosthetic arteriovenous grafts.
