Positive predictive values sensitivity, calculated as measures, varied widely between studies, differing with regard to autopsy rates, amount information on medical records, period investigated. However, which has been frequently assigned certificates Japan, was validated some studies. Half these evaluated be sudden deaths, including deaths. Because autopsy-based deaths indicated that 30-50% accounted failure should taken into consideration order determine actual number Japan. Focusing changes vital after 1995 ICD revision, Oita Cardiac Death Surveys (OCDS) allowed interpretation its effects failure. Much increase reflects more false positive cases, particularly out-of-hospital Considering Japanese features CHD, further epidemiological are needed confirm diagnoses monitor trends
