Step 1: Score;

Step 2: Sum all scores;

Step 3: Determine absolute risk based on the total score and compare it with the reference standards for ICVD risk.

Important Notes:

1. This risk assessment tool is only applicable to individuals who have not yet developed cardiovascular diseases. If cardiovascular disease has already occurred, the probability of subsequent events is significantly higher than predicted by the model.

2. Since the endpoint events in this study do not include angina pectoris, the absolute risk derived for ICVD is lower than the actual risk. Clinical applications should consider this. According to Framingham data, the absolute risk for coronary heart disease events, whether or not angina is included, differs by an average of 3%-5% in individuals over 40, with larger discrepancies as age increases.

3. The study population's age range was 35-59 years; results from the predictive model and assessment methods applied outside this age range should be considered for reference only.

4. The predictive model and assessment method are most suitable for individuals with mild to moderate elevations in various risk factors. There may be significant errors for individuals with multiple high-risk factors, which are not common in the population.

5. This method only assesses the risk of developing the disease within 10 years. For younger individuals, low risk often results from youth and does not imply lifelong low risk. Therefore, calculating relative risk based on average and minimum risk is more appropriate for determining the necessity of intervention.
