What is the prognostic value of angiographic indices of coronary artery disease from the Coronary Artery Surgery Study (CASS)?
Ringqvist et al. (1994) studied the prognostic value of angiographic indices of coronary artery disease from the Coronary Artery Surgery Study (CASS). They found that the angiographic indices provided a strong prognostic value in predicting long-term survival in the CASS Registry. Specifically, they found that patients with an ejection fraction of less than 0.40 had a higher mortality compared to those with an ejection fraction of greater than 0.40. They also found that the presence of multiple lesions and a left ventricular ejection fraction of greater than 0.40 were associated with a higher risk of death.
