Coronary heart disease: an expensive Air Force problem
Insights
Coronary heart disease (CHD) poses a significant public health risk, costing the Air Force millions annually. Preventive programs aim to reduce premature death and disability by identifying and treating high-risk individuals.
Area of Science:
- Cardiovascular Health
- Aerospace Medicine
- Public Health
Background:
- Coronary heart disease (CHD) presents a major public health challenge, incurring substantial costs for the Air Force.
- Atherosclerosis affects a significant percentage of Air Force pilots, posing a risk of in-flight incapacitation.
- The underlying mechanisms of CHD development are complex and not fully understood.
Purpose of the Study:
- To discuss the significance of various risk factors for CHD.
- To outline preventive strategies for CHD in high-risk populations.
- To evaluate the utility of diagnostic tests for asymptomatic CHD.
Main Methods:
- Review of existing literature on CHD risk factors and preventive programs.
- Description of HEW's Multiple Risk Factor Intervention Trial (MRFIT) and USAF's HEART program.
- Analysis of the costs, benefits, risks, sensitivity, and predictive value of CHD screening tests.
Main Results:
- CHD is a multifactorial condition with various associated risk factors.
- Preventive programs can potentially reduce CHD incidence and its associated costs.
- Available screening tests for asymptomatic CHD vary in their diagnostic accuracy and clinical utility.
Conclusions:
- Early identification, education, and treatment of high-risk individuals are crucial for mitigating CHD.
- Targeted preventive programs show promise in reducing premature death and disability from CHD.
- Careful consideration of test characteristics is necessary when screening asymptomatic individuals for CHD.
Abstract:
Death or disability from CHD is a major public health problem that costs the Air Force about $50 million annually. Statistically, 20% of 30,000 pilots in the Air Force could have a significant degree of coronary atherosclerosis. In-flight incapacitation due to "heart attack" is a real possibility. Fortunately, aircraft accidents related to coronary events have been very uncommon. The basic mechanisms leading to the development of CHD, a multifactorial condition, are not fully understood. The significance of various risk factors associated with an increased incidence of CHD are discussed. It is hoped that preventive programs designed to identify, educate, and treat those at high risk will reduce the incidence of premature death and disability due to CHD. Two such programs (HEW's MRFIT and USAF's HEART) are briefly described. The costs, benefits, risks, sensitivity, and predictive value of tests available to detect CHD in asymptomatic individuals are outlined.
