We included all deaths (n=6629) and identified 314 autopsied cases of SCD, 40 of whom (13%) died from CAD. To compare symptoms before death, the CAD case group was sex- and age-matched 1:2 with a control group randomly sampled from a population of 1497 individuals who had died in accidents. We used data from the National Patient Registry on previous contacts with the healthcare system for all persons and read all available patient records, including death certificates and autopsy reports.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 31 (79%) persons with CAD-SCD had cardiac symptoms such as angina pectoris (n=24, 62%) and dyspnoea during the 12\u2005months before death, and this was significantly higher than in the control group (p&lt;0.001). In the case group, 18 persons (46%) had contacts with the healthcare system for cardiac symptoms before death, and this was also significantly higher than the control group (p&lt;0.001).<\/jats:p>\n
