Risk predictors for adverse outcomes after percutaneous coronary interventions and their related costs.

Objectives: During recent years, numerous clinical and procedural risk factors for adverse outcomes after percutaneous coronary interventions (PCI) have been identified. Due to the high economic pressure in many national health care systems, it is of some interest whether these predictors of clinical risks represent also the main cost drivers.

Methods: Data of 770 patients undergoing PCI were retrospectively analyzed.

Impact of haemoglobin concentration and chronic kidney disease in patients with coronary heart disease undergoing percutaneous coronary interventions.

Background: A few recent studies suggested that anaemia has a marked impact on the survival of patients with coronary heart disease (CHD). However, all of these analyses did not take into consideration that chronic kidney disease (CKD) plays an important role in erythropoiesis and anaemia. Therefore, we assessed in this study whether anaemia is an independent predictor of mortality or if its impact was confounded by CKD, which is known to have itself a marked impact on outcomes of patients with CHD.
