The article studies on the main factors supposed to have relationship with heart disease suffering, such as aging, smoking status, alcohol intake status and family history. By using Chi-square Test/Fisher Test as well as Monte Carlo Simulation and logistic regression, the article receives expected results that smoking, alcohol intake and aging both have positive correlation with heart disease suffering with smoking owning a greater impact on heart disease. The significance of this paper is to verify the positive correlation between each factor and the risk of heart disease, and to compare the biggest influence factors on the risk of heart disease.
