What are the long-term survival rates for medically treated patients in the Coronary Artery Surgery Study (CASS) Registry?
The long-term survival rates for medically treated patients in the Coronary Artery Surgery Study (CASS) Registry were evaluated by Emond et al. (1994). They found that the overall 5-year survival rate for medically treated patients was 82%, with survival rates declining with increasing age, lower ejection fraction, and the presence of left main coronary artery disease.
