Men between the ages of 46 and 90 years old were classified according to how many anger symptoms they exhibit and whether they have coronary heart disease or not. Among 588 men with the most anger symptoms, 53 had coronary heart disease. Among 195 men with no anger symptoms, 12 had coronary heart disease.

For those with the most anger symptoms, what is the percent increase in the risk of heart disease? (Round the answer to the nearest whole number.)? SHOW YOUR WORK.

Expert Solution

From the given data, the following Table is calculated:

Coronary heart disease No Coronary heart disease Total Cumulative Incidence
Anger 53 535 588 53/588=0.0901
No anger 12 183 195 12/195=0.0615
Total 65 718 783

Risk Ratio (RR) is given by:

The percent increase in the risk of heart disease = (RR - 1) X 100

                                                                       = (1.4641 - 1) X 100

                                                                        = 46%

So,

Answer is:

46%
