What is the prognostic value of angiographic indices of coronary artery disease from the Coronary Artery Surgery Study (CASS)?
The prognostic value of angiographic indices of coronary artery disease from the Coronary Artery Surgery Study (CASS) was demonstrated in a study published in the Journal of Clinical Investigation in 1983. This study followed patients for up to ten years and found that angiographic indices of coronary artery disease were strong predictors of survival and myocardial infarction. Additionally, the study showed that angiographic severity of coronary narrowing was a good surrogate marker for the extent of coronary atherosclerosis. Further studies have since confirmed this finding.
