Subjects exhibiting a behavior pattern (type A) previously found to be associated with a high prevalence and incidence rate of clinical coronary heart disease (CHD) and patients suffering from clinical coronary heart disease were subjected to a specially designed "voice analysis" test. Approximately 84% of the type A subjects and 76% of the patients with CHD responded to this test in a manner that allowed their differentiation from well subjects exhibiting a behavior pattern (type B) previously found to be associated with a low prevalence and incidence rate of CHD.
