The psychosocial data (e.g. anger-expression, stressful life events) and some medical data (e.g. blood pressure, smoking) were collected in 1971/72, while additional information about other medical risk factors was collected in 1968/69. Mortality ascertainment and cause of death was completed by the end of 1989, through TCHS staff, using the National Death Index (NDI). The estimated cumulative 18-year mortality rate as of 1989 for the Tecumseh cohort of the same age as the LCES sample was 26 percent for males and 16 percent for females. Approximately 144 deaths were expected. Out of the total TCHS cohort deaths, 35 percent were estimated to be due to CHD. Research questions tested included: (1) did suppressed anger predict coronary heart disease mortality as well as all-cause mortality; (2) was the relationship between suppressed anger and mortality modified by other risk factors (e.g. blood pressure, marital stress, gender); (3) were there certain anger-coping strategies among married couples which increased mortality risk for one or both members of the marital pair.
