Risk stratification and outcome assessment in cardiac surgery and transcatheter interventions

There is a steady increase in the number of patients undergoing cardiac surgery in The Netherlands [1]. As can be appreciated from Figure 1, 16,877 adult surgical cardiac procedures were performed in 2008. In addition, the number of transcatheter procedures, including valve and coronary stent implantation, is also growing rapidly. Given the ageing of the population and the increasing number of patients with congenital heart disease that reaches adulthood, the number of surgical and transcatheter interventions is likely to increase even further [2, 3]. The growing population requiring these cardiovascular interventions will lead to an increase in health care expenditure. This calls for a cost-effective approach of health care, with constant attention for the relation between cost-effectiveness and quality of care. Quality assessment is an inherent component of this approach. In addition, by improving the quality of care (including optimizing treatment selection), fewer adverse outcomes are to be expected, with a subsequent restraint of costs

Impact of thrombus burden on long-term clinical outcomes in patients with either anterior or non-anterior ST-segment elevation myocardial infarction

Large thrombus burden (LTB) during ST-segment elevation myocardial infarction (STEMI) could translate into worse clinical outcomes. The impact of a LTB in terms of long-term clinical outcomes on different myocardial infarct territories has not yet been fully evaluated. From April 2002 to December 2004, consecutive patients with STEMI undergoing percutaneous coronary intervention with drug eluting stent were evaluated. The study sample was stratified in two groups: anterior STEMI and non-anterior STEMI. LTB was considered as a thrombus larger than or equal to 2-vessel diameters, and small thrombus burden less than 2-vessel diameters. Major adverse cardiac events (MACE) were evaluated at 10-year and survival data were collected up to 15-year. A total of 812 patients were evaluated, 6 patients were excluded due to inadequate angiographic images, 410 (50.9%) had an anterior STEMI and 396 (49.1%) a non-anterior STEMI. Patients with LTB had higher rates of 10-year mortality (aHR 2.27, 95%CI 1.42–3.63; p = 0.001) and 10-year MACE (aHR 1.46, 95%CI 1.03–2.08; p = 0.033) in anterior STEMI, but not in non-anterior STEMI (aHR 0.78, 95%CI 0.49–1.24; p = 0.298; aHR 0.71, 95%CI 0.50–1.02; p = 0.062). LTB was associated with increased 30-day mortality (aHR 5.60, 95%CI 2.49–12.61; p < 0.001) and 30-day MACE (aHR 2.72, 95%CI 1.45–5.08; p = 0.002) in anterior STEMI, but not in non-anterior STEMI (aHR 0.39, 95%CI 0.15–1.06; p = 0.066; aHR 0.67, 95%CI 0.31–1.46; p = 0.316). Beyond 30-day, LTB had no impact on mortality and MACE in both groups. In anterior STEMI, LTB is associated with worse long-term clinical outcomes, this effect was driven by early events.

Risk stratification for adult congenital heart surgery

Objective: At this moment, no risk stratification models are available for adult congenital cardiac surgery. This study aims to identify a suitable stratification tool for the adult congenital heart surgery population. Pediatric congenital cardiac surgery score models were therefore tested in an adult congenital population. In addition, an age component was added to these models and performance was compared with the original score systems. Methods: The Risk Adjustment in Congenital Heart Surgery (RACHS-1), Basic Aristotle Score, Society of Thoracic Surgeons (STS)-European Association for Cardiothoracic Surgery (EACTS) Score and Comprehensive Aristotle Score were calculated for all adult patients who underwent congenital cardiac surgery between January 1990 and January 2007 in a single center (N = 963). In addition, an age component was added to these models. Discrimination was then tested for all models with and without the age component. Results: Application of the original pediatric risk scores resulted in c-statistics for 30-day mortality of 0.60, 0.60, 0.60, and 0.66 respectively. Combining these models with the age component resulted in significantly higher c-statistics of 0.69, 0.70, 0.69, and 0.76 respectively. Age as a sole predictor already resulted in a c-statistic of 0.67. Comparable results were found for 1-year mortality. Conclusions: The discriminatory power of the pediatric risk scores was suboptimal, but increased when adding age as a score component. The best performance was achieved by the combination of age and the Comprehensive Aristotle Score, for both 30-day and 1-year mortality. (C) 2010 European Association for Cardio-Thoracic Surgery.
