Cardiovascular diseases are leading causes of death worldwide. Many efforts have been paid on understanding the underlying mechanisms and causes. However, identifying their risk factors and individual impacts on the diseases onset and progression might be the most effective ways, since specific solutions and treatments can be applied. Survival analysis is a statistical method and approach to identify potential factors and also their effects. Furthermore, it provides the power to predict when cardiovascular diseases might occur given those potential risk factors. This book introduces theories and methods of survival analysis, and also offers some mathematical deductions for conclusions. Therefore, it can be used as a reference book for senior undergraduates and graduates who are interested in the field. In addition, it also describes detail procedures for analysis.
