A coronary index assessing the site, severity, and number of lesions significantly predicted survival over 5 years, with an index of 25% or less identifying a high-risk group.

Does a coronary index based on arteriography predict mortality in medically treated patients with coronary artery disease?
A comprehensive coronary angiographic index incorporating the site, severity, and number of lesions strongly predicts 5-year survival in medically treated patients with coronary artery disease.
An index of severity of coronary artery disease is described which takes into account the site, severity and number of all lesions in the coronary arteries. A percentage figure is computed with low percentages indicating severe disease. Ten year follow-up for 1050 medically treated patients are given. During the period of observation the overall mortality rate was 6.3%. 68% of deaths occurring in the first year and 97% in the first five years. Survival curves are drawn for five years and cindicate significant differences in survival between the four quartikes of the coronary index. In particular, a high risk group is described with a coronary index of 25% or less. Left ventricular abnormalities further decrease the survival rates.
R Balcon (Mon,) conducted a cohort in Coronary artery disease (n=1,050). Coronary index (severity of coronary artery disease) vs. Different quartiles of the coronary index was evaluated on Survival / mortality. A coronary index assessing the site, severity, and number of lesions significantly predicted survival over 5 years, with an index of 25% or less identifying a high-risk group.
