Preserved EF may refine mortality risk stratification in 3-vessel CAD; leaves open superiority over other indices in modern cohorts.
Does left ventricular ejection fraction predict mortality better than other clinical and hemodynamic indices in patients with medically-treated coronary artery disease?
Left ventricular ejection fraction is a more powerful predictor of short-term mortality than other hemodynamic, angiographic, or electrocardiographic indices in patients with medically managed coronary artery disease.
Nelson et al. (1975) studied this question.
