Segment 1 Opening credits show commuters on a busy London street, traffic, fumes, cigarette smoking, frying food, callipers measuring skin fat and a blood pressure gauge. Rose introduces the subject and points out how difficult it is to make an epidemiological study of arteriosclerosis. He shows a table listing statistics for 1000 average young British men between the ages of 30 and 65. He explains the statistics showing how many of them will have died from coronary heart disease before they reach retirement age. He then compares this data with equivalent tables from other countries including Japan and Finland. Time start: 00:00:00:00 Time end: 00:05:31:12 Length: 00:05:31:12
Segment 2 Rose compares the statistics of deaths from arteriosclerosis before retirement age in different UK regions. He discusses some environmental factors which may influence this data, such as whether a region has hard or soft water. He refers to some charts showing standardised mortality ratios from heart disease in the UK and US and compares the change in trends in the two over the last ten years.

Segment 3 Rose talks now about non-fatal heart disease in the community. He explains how about 10% of working men might have a degree of ischeamia and not realise it. In addition to this, within a year, those with evidence of heart disease may have either progressed to heart attack or reverted to ther previous disease-free status. He concludes that the main line of treatment should be towards prevention as many heart attacks are untreatable by the time of occurance.

Segment 4 Rose shows a chart depicting risk factors for coronary heart disease. He plots mortality agains age and sex. He discusses the data in this chart in depth, considering hormone differences between men and women as differentiating factors, as well as activity levels and social factors such as smoking, which women tend to do less. Time start: 00:14:18:00 Time end: 00:20:48:00 Length:00:06:30:00
Segment 5 Rose continues to look at risk factors for coronary artery disease and now focuses on cholesterol. He shows a graph which charts out the ratio of cholesterol to likelihood of heart disease. He explains in detail what cholesterol actually is and introduces the subject of tobacco smoking in relation to heart disease. Time start: 00:20:48:00 Time end: 00:25:38:12 Length: 00:05:10:12
Segment 6 Rose discusses the relationship between smoking and heart disease in depth. He explains how recent research has proved the link between smoking and arteriosclerosis, then moves on to talk about combined risk factors leading to a coronary event; for instance a smoker with a high cholesterol level would be much more likely to suffer from heart disease because of the two separate risk factors combined. Time start: 00:25:38:12 Time end: 00:29:20:20 Length: 00:03:42:08
Segment 7 Rose talks about the relationship between the level of physical activity a person typically makes and their risk of arteriosclerosis. He refers to a study based on civil servants who get little or no exercise each week and who were more likely to suffer from arteriosclerosis, then a further study comparing arteriosclerosis in men who do different levels of exercise. Rose then shows tables and charts combining risk factors of lack of exercise, smoking and cholesterol and plots them against heart disease statistics. Time start: 00:29:20:20 Time end: 00:35:00:13 Length: 00:07:39:05
Segment 8 Rose concludes the lecture by looking at risks to a community at large. The results of research he looks into show that risk to the community is far greater when a lot of people are at a slight risk of arteriosclerosis than it is when a small amount of people are at a high risk.
