NOTE: A scoring system based on the PROCAM study is discussed above.
Patient selection: male aged 40 to 65 years
Outcome: major coronary event (fatal AMI, nonfatal AMI, sudden cardiac death)
Parameters:
(1) age in years
(2) systolic blood pressure in mm Hg
(3) LDL cholesterol in mg/dL
(4) HDL cholesterol in mg/dL
(5) triglycerides in mg/dL
(6) cigarette smoking
(7) diabetes mellitus
(8) family history of myocardial infarction
(9) angina pectoris
