using hazard ratios for generating data

A question:

If I have several Hazard ratios (with their 95% confidence intervals) for several risk factors for the development of a disease, and I want to simulate several subjects characterized by these risk factors (has the factor = 1, or does not have the factor = 0) based on the fact that these subjects are classified at a high, medium or low risk of having that disease. Is this possible? and how do I generate these subjects?
