Depending on age, sudden death s the first symptom in 15-30 of all new coronary events in persons with previously unsuspected coronary disease. The prevalence of unrecognized but severe coronary artery disease in an apparently healthy population age 35-55 is conservatively estimated at 1000 to 2000 per 10,000. The annual incidence of new documented first infarct in this age group ranges from 50-100 per 10,000. The incidence of sudden death without prior suspicion of heart disease ranges from 20-50 per 10,000, and 35-50 of these subjects at autopsy will have prior clinically unrecognized healed myocardial infarction. Based on the fundamental work done in evaluating asymptomatic aircrewmen by a number of workers at USAFSAM, it seems prudent to assume these statistics also apply to the pilot population. It follows from these statistics that sudden death in pilots at the controls of high-performance aircraft can be expected at the rate or at least 1 per year for every 10,000 pilots over age 35 who fly on the average of 300 hours per year. By using published figures for the costs of such high-performance aircraft, the annual cost to be published figures for the cost of such high-performance aircraft, the annual to the Air Force for lost aircraft from this cause alone is considered to be in the millions of dollars.
