Overlap between the classification of coronary heart disease mortality (as a cause of death) and sudden cardiac death (as a mode of death). Among all 2303 participants who died during follow‐up, 780 died due to cardiovascular disease, of which 431 participants were classified as coronary heart disease mortality. Of these 431 participants, 187 were also classified as sudden cardiac death. Seventeen participants were classified as sudden cardiac death and cardiovascular deaths (but not coronary heart disease) and 13 participants were classified as sudden cardiac death but could otherwise not be classified as cardiovascular deaths.
