Self-administration of a questionnaire on chest pain and intermittent claudication
Insights
Self-administered questionnaires effectively identify men at high risk for coronary heart disease. This screening method aids in early detection of conditions like angina and infarction, improving cardiovascular risk assessment.
Area of Science:
- Cardiology
- Public Health
- Epidemiology
Background:
- Coronary heart disease (CHD) poses a significant public health challenge.
- Accurate screening tools are crucial for identifying individuals at high risk.
Purpose of the Study:
- To evaluate the effectiveness of a self-administered questionnaire for screening chest pain and intermittent claudication.
- To compare the yield and predictive value of a self-administered questionnaire versus interviewer-based methods for CHD risk.
Main Methods:
- A screening examination involving 18,403 men aged 40-64 years.
- Utilized a self-administered London School of Hygiene questionnaire for symptoms of angina and possible infarction.
- Correlated questionnaire results with electrocardiographic (ECG) findings and five-year coronary mortality risk.
Main Results:
- The self-administered questionnaire identified "angina" and "history of possible infarction" at approximately twice the rate of interviewer methods.
- Groups identified by both methods showed similar associations with ECG findings and CHD risk prediction.
- Five-year coronary mortality risk varied significantly, from 0.9% (negative on both measures) to 16% (angina and positive ECG).
Conclusions:
- Self-administered questionnaires offer a convenient and effective method for identifying individuals at high risk of major coronary heart disease.
- This approach facilitates early identification and potential intervention for cardiovascular disease.
Abstract:
A total of 18 403 men aged between 40 and 64 years took part in a screening examination which included a self-administered version of the London School of Hygiene questionnaire on chest pain and intermittent claudication. The yield of positives for "angina" and "history of possible infarction" was about twice as high as with interviewers, but the positive groups obtained by the two techniques differed little in their association with electrocardiographic findings or in their ability to predict five-year coronary mortality risk. This risk ranged from 0-9% in men negative to questionnaire and electrocardiograms (ECG), to 4-3% for those with positive ECG but no symptoms, 4-5% for those with angina and negative ECG, up to 16% for those with angina and positive ECG. The self-administered version of this questionnaire provides a simple and convenient means of identifying individuals with a high risk of major coronary heart disease.
