REVIEW ER 'S CONCLUSIONS Quitting smoking is associated with a substantial reduction in risk of all-cause mortality among patients with CHD .
This 36 % risk reduction appears substantial compared with other secondary preventive therapies such as cholesterol lowering which have received greater attention in recent years .
The risk reduction associated with quitting smoking seems consistent regardless of differences between the studies in terms of index cardiac events , age , sex , country , and time period .
BACKGROUND Although the importance of smoking as a risk factor for coronary heart disease is beyond doubt , the speed and magnitude of risk reduction when a smoker with coronary heart disease quits are still subjects of debate .
OBJECTIVES To estimate the magnitude of risk reduction when a patient with CHD stops smoking .
Quitting and restarting smoking: cohort study of patients with angina in primary care
Smoking is the most important modifiable risk factor for coronary heart disease and its reduction is a target for primary health care.1 The participants in most studies of the smoking habits of patients with coronary heart disease are enrolled after acute cardiac events.2 There are few documented studies of the changes in the smoking habits of patients with angina . This study examined variations in self reported smoking habits over a five year period in a primary care cohort of patients diagnosed as having angina . Patients clinical ly diagnosed as having angina at least six months previously were identified from the disease registers of 18 general practice s in the Greater Belfast area . These general practice s were chosen to
