Assmann et al developed a simple risk score for predicting the risk of an acute coronary event based on the Prospective Cardiovascular Munster (PROCAM) study. This can help identify a patient who may benefit from an intervention to reduce cardiovascular risk. The authors are from the University of Munster.
Patient selection: 35 to 65 years of age
Acute coronary event was either an acute myocardial infarction or death following a myocardial infarction.
Parameters:
(1) age in years
(2) serum LDL cholesterol
(3) serum HDL cholesterol
(4) serum triglycerides
(5) cigarette smoking
(6) diabetes mellitus
(7) family history of myocardial infarction
(8) systolic blood pressure in mm Hg

Interpretation:
• minimum score: 0
• maximum score: 87
• The higher the score the greater the risk of an acute coronary event within the next 10 years.
