Preoperative anaemia and outcome after elective cardiac surgery: a Dutch national registry analysis.

Background: Previous studies have shown that preoperative anaemia in patients undergoing cardiac surgery is associated with adverse outcomes. However, most of these studies were retrospective, had a relatively small sample size, and were from a single centre. The aim of this study was to analyse the relationship between the severity of preoperative anaemia and short- and long-term mortality and morbidity in a large multicentre national cohort of patients undergoing cardiac surgery.

Impaired right ventricular ejection fraction after cardiac surgery is associated with a complicated ICU stay.

Background: Right ventricular (RV) dysfunction is a known risk factor for increased mortality in cardiac surgery. However, the association between RV performance and ICU morbidity is largely unknown.

Methods: We performed a single-centre, retrospective study including cardiac surgery patients equipped with a pulmonary artery catheter, enabling continuous right ventricular ejection fraction (RVEF) measurements.

Right Ventricular Function After Cardiac Surgery Is a Strong Independent Predictor for Long-Term Mortality.

Objective: To establish the all-cause mortality of right ventricular dysfunction after cardiac surgery in a heterogeneous group of cardiac surgery patients.

Design: Retrospective analysis of a heterogeneous group of 1,109 cardiac surgery patients in a 4-year period.

Setting: Single-center study in a tertiary teaching hospital.
