To confirm the usefulness of the cardiac risk index published by Goldman and associates in 1977, the author did a separate, prospective study of 1140 patients over the age of 40 years who underwent noncardiac surgical procedures. Four risk categories were defined (classes I to IV, low to high risk according to Goldman's point score). Percentages of postoperative cardiac events (life-threatening cardiac complications or cardiac death) were tabulated. The incidence of cardiac events for each risk category, classes I to IV, was 0.7%, 3%, 15% and 30%, respectively. Comparisons with Goldman's original study demonstrate that the cardiac risk index is a reliable, objective and valid method of assessing cardiac risk in patients who undergo elective surgery.
为证实戈德曼及其同事于1977年公布的心脏风险指数的实用性，作者对1140例40岁以上接受非心脏外科手术的患者进行了一项独立的前瞻性研究。定义了四个风险类别（I至IV级，根据戈德曼评分从低到高风险）。将术后心脏事件（危及生命的心脏并发症或心脏死亡）的百分比制成表格。I至IV级每个风险类别的心脏事件发生率分别为0.7%、3%、15%和30%。与戈德曼的原始研究相比表明，心脏风险指数是评估接受择期手术患者心脏风险的一种可靠、客观且有效的方法。
