Decreasing prevalence but increasing importance of left ventricular dysfunction and reoperative surgery in prediction of mortality in coronary artery bypass surgery: Trends over 18 years

Whereas the prevalence of most risk factors increased with time, left ventricular dysfunction and reoperative CABG became significantly less common. However, the odds of mortality associated with these 2 predictors increased, indicating that although they occur less commonly, these 2 risk factors paradoxically play an increasingly important role in determining patient outcomes.
