Eight generally accepted heart disease risk factors (age, sex, family history, blood pressure, cholesterol, weight, smoking and exercise) were used in the computation of a cardiac index (RISKO) for 4,066 safety personnel of the County of Los Angeles. Seventy-one individuals subsequently developed coronary disease. The index had significant value in identifying the individuals who were to develop symptomatic coronary disease, and its discriminative power was comparable to the power of the Framingham index.
研究采用了八个普遍认可的心脏病风险因素（年龄、性别、家族病史、血压、胆固醇、体重、吸烟和运动），为洛杉矶县的4066名安全人员计算心脏指数（RISKO）。随后有71人患上冠心病。该指数在识别即将出现症状性冠心病的个体方面具有显著价值，其判别能力与弗雷明汉姆指数相当。
