Key result
A five-point clinical risk scale successfully estimated the likelihood of severe coronary disease, identifying three-vessel or left-main disease in 48% of high-risk and 9% of low-risk patients.

Can simple clinical and resting electrocardiographic variables predict the probability of three-vessel or left-main coronary artery disease in patients with symptomatic CAD?
A simple five-point clinical risk scale using age, typical angina, diabetes, gender, and prior MI can effectively estimate the likelihood of severe (three-vessel or left-main) coronary artery disease.
Bradley Hubbard (1992) conducted an observational in Symptomatic coronary artery disease (n=680). Five-point clinical risk scale (age, typical angina, diabetes, gender, prior MI) was evaluated on Probability of three-vessel or left-main coronary artery disease. A five-point clinical risk scale successfully estimated the likelihood of severe coronary disease, identifying three-vessel or left-main disease in 48% of high-risk and 9% of low-risk patients.
