Cost-effectiveness of percutaneous coronary intervention with drug-eluting stents in patients with multivessel coronary artery disease compared to coronary artery bypass surgery five-years after intervention

Cost‐effectiveness of percutaneous coronary intervention (PCI) using drug‐eluting stents (DES), and coronary artery bypass surgery (CABG) was analyzed in patients with multivessel coronary artery disease over a 5‐year follow‐up.

Outcome after Elective Percutaneous Coronary Intervention Depends on Age in Patients with Stable Coronary Artery Disease - An Analysis of Relative Survival in a Multicenter Cohort and an OCT Substudy.

Background Age is a strong predictor of survival in patients with coronary artery disease. In elder patients with increasing co-morbidities percutaneous coronary intervention (PCI) is associated with more complications and worse outcome. The calculation of relative survival rates adjusts for the “background” mortality in the general population by correcting for age and gender. We analyzed if elder patients after elective PCI have a worse relative survival compared to younger patient groups. Methods A total of 8,342 patients who underwent elective PCI at two high volume centers between 1998 and 2009 were analyzed. Results The survival of our patients after PCI (observed survival) was slightly lower compared to the general population (expected survival) resulting in a slightly decreasing relative survival curve. In a multivariate Cox regression model age amongst others was a strong predictor of survival. Stratifying patients according to their age the relative survival curves of younger patients (Quartile 1: <58 years; 2,046 patients), elder patients (Quartile 3: 66–73 years; 2,090 patients) and very old patients (Quartile 4: >73 years; 2,307 patients) were similar. The relative survival of mid-aged patients (Quartile 2: 58–65 years; 1,899 patients) was better than that of all other patient groups. The profile of cardiovascular risk factors differs between the various groups resulting in different composition and burden of coronary plaques in an optical coherence tomography sub-study. Conclusion Patients after elective PCI have a slightly worse long-term survival compared to the age- and sex-matched general population. This is also true for different groups of age except for mid-aged patients between 58 and 63 years. Elder patients between 66 and 73 years and above 73 years have a similar relative survival compared to younger patients below 58 years, and might therefore have similar benefit from elective PCI.

THE COURSE OF NT-PROBNP IN REAL-LIFE PATIENTS UNDERGOING TRANSFEMORAL AORTIC VALVE IMPLANTATION

NT-proBNP has been reported as predictor of survival in severe aortic stenosis (AS). Aim of this study was to examine the change in NT-proBNP levels over time and its value as predictor of outcome after treatment with transfemoral aortic valve implantation (TAVI). From May 2007 until June 2013, 142

COST-EFFECTIVENESS OF PERCUTANEOUS CORONARY INTERVENTION WITH TAXUS STENTS IN PATIENTS WITH MULTIVESSEL CORONARY ARTERY DISEASE COMPARED WITH AORTOCORONARY BYPASS SURGERY 5 YEARS AFTER INTERVENTION

Cost-effectiveness of percutaneous coronary intervention (PCI) using drug-eluting stents (DES) was compared to the costs of coronary artery bypass surgery (CABG) in patients with multivessel coronary artery disease in the first 5 years follow-up (FUP). 199 patients with multivessel DES-PCI (n=114,
