Therefore, an alternative approach to summarizing wait-list data is to estimate the proportion of patients dying before surgery by a certain time and the proportion of patients dying by a certain time among those who have not received treatment by that time .

A patient who presents with symptoms of coronary artery disease is referred to a cardiologist, who evaluates the results of coronary angiography and recommends treatment.
