ObjectivesTo evaluate the risk of aortic aneurysm in patients with giant cell arteritis (GCA) compared with age-, gender- and location-matched controls.MethodsA UK General Practice Research Database (GPRD) parallel cohort study of 6999 patients with GCA and 41 994 controls, matched on location, age and gender, was carried out. A competing risk model using aortic aneurysm as the primary outcome and non-aortic-aneurysm-related death as the competing risk was used to determine the relative risk (subhazard ratio) between non-GCA and GCA subjects, after adjustment for cardiovascular risk factors.ResultsComparing the GCA cohort with the non-GCA cohort, the adjusted subhazard ratio (95% CI) for aortic aneurysm was 1.92 (1.52 to 2.41). Significant predictors of aortic aneurysm were being an ex-smoker (2.64 (2.03 to 3.43)) or a current smoker (3.37 (2.61 to 4.37)), previously taking antihypertensive drugs (1.57 (1.23 to 2.01)) and a history of diabetes (0.32 (0.19 to 0.56)) or cardiovascular disease (1.98 (1.50 to 2.63)). In a multivariate model of the GCA cohort, male gender (2.10 (1.38 to 3.19)), ex-smoker (2.20 (1.22 to 3.98)), current smoker (3.79 (2.20 to 6.53)), previous antihypertensive drugs (1.62 (1.00 to 2.61)) and diabetes (0.19 (0.05 to 0.77)) were significant predictors of aortic aneurysm.ConclusionsPatients with GCA have a twofold increased risk of aortic aneurysm, and this should be considered within the range of other risk factors including male gender, age and smoking. A separate screening programme is not indicated. The protective effect of diabetes in the development of aortic aneurysms in patients with GCA is also demonstrated.
AimsHeart transplantation (HTx) is limited by the scarcity of suitable donor hearts. Consequently, more patients with advanced heart failure require a ventricular assist device (VAD). We report UK activity, trends, and outcome for longterm VAD support as a bridging therapy to HTx. Overall, 46 patients received a first-generation device, 80 a second-generation device, and 121 a third-generation device. Use of third-generation devices increased from ,6% in E1 to 78% in E3. Median duration of LVAD support increased from 141 days in E1 to 578 days in E3 (P , 0.001). Overall survival to 1 year after LVAD implant rose from 58.3% [95% confidence interval (CI) 40.7-72.4%] in E1 to 72.5% (95% CI 63.3-79.8%) in E3 (P ¼ 0.21), and improved significantly with device generation; at 1 year, 50% of patients with first-generation devices were alive compared with 68.1% and 76.9% of patients with second-and third-generation devices, respectively (P ¼ 0.002). These differences remained after risk adjustment. HTx following LVAD implant reduced over time (P , 0.001).

Patients
ConclusionVAD activity and duration of support have increased. There has been a shift from first-and second-to third-generation devices, and an associated improvement in survival.--
