    • BACKGROUND: Early detection of coronary atherosclerosis using coronary computed tomography angiography (CCTA), in addition to coronary artery calcification (CAC) scoring, may help inform prevention strategies. We used CCTA to determine the prevalence, severity, and characteristics of coronary atherosclerosis and its association with CAC scores in a general population.METHODS: We recruited 30 154 randomly invited individuals age 50 to 64 years to SCAPIS (the Swedish Cardiopulmonary Bioimage Study). The study includes individuals without known coronary heart disease (ie, no previous myocardial infarctions or cardiac procedures) and with high-quality results from CCTA and CAC imaging performed using dedicated dual-source CT scanners. Noncontrast images were scored for CAC. CCTA images were visually read and scored for coronary atherosclerosis per segment (defined as no atherosclerosis, 1% to 49% stenosis, or ≥50% stenosis). External validity of prevalence estimates was evaluated using inverse probability for participation weighting and Swedish register data.RESULTS: In total, 25 182 individuals without known coronary heart disease were included (50.6% women). Any CCTA-detected atherosclerosis was found in 42.1%; any significant stenosis (≥50%) in 5.2%; left main, proximal left anterior descending artery, or 3-vessel disease in 1.9%; and any noncalcified plaques in 8.3% of this population. Onset of atherosclerosis was delayed on average by 10 years in women. Atherosclerosis was more prevalent in older individuals and predominantly found in the proximal left anterior descending artery. Prevalence of CCTA-detected atherosclerosis increased with increasing CAC scores. Among those with a CAC score >400, all had atherosclerosis and 45.7% had significant stenosis. In those with 0 CAC, 5.5% had atherosclerosis and 0.4% had significant stenosis. In participants with 0 CAC and intermediate 10-year risk of atherosclerotic cardiovascular disease according to the pooled cohort equation, 9.2% had CCTA-verified atherosclerosis. Prevalence estimates had excellent external validity and changed marginally when adjusted to the age-matched Swedish background population.CONCLUSIONS: Using CCTA in a large, random sample of the general population without established disease, we showed that silent coronary atherosclerosis is common in this population. High CAC scores convey a significant probability of substantial stenosis, and 0 CAC does not exclude atherosclerosis, particularly in those at higher baseline risk.

  • Erik den heliges skelett
  • 2016

    • No contemporary sources mention Erik Jedvardsson, Sweden's king saint. The only account of his life is the saint's legend, in its preserved form written in the late 13th century, and legends are notoriously untrustworthy. It says that in 1160, in the tenth year of Erik's reign, he was killed by a throne claimant. His remains have rested in a reliquary in Uppsala Cathedral since 1257 at the latest and survived the Reformation. A thorough investigation was made in 1946, and the development of new methods motivated a new investigation in 2014. 23 bones remain that apparently belong to the same individual. (They are accompanied in the reliquary by an unrelated shinbone.) Radiocarbon values are consistent with a death in 1160. The bones belong to a man, 35-40 years old, about 171 cm tall, without any discernible medical conditions. Bone density indicates a life of good nourishment and abundant exercise. The skull has one or two healed wounds that may have been due to weapons. Isotope analysis points to a diet rich in freshwater fish. Stable isotopes also imply that he did not spend his last decade in the expected Uppsala area but rather in Västergötland further south. Insufficient reference materials however make this a very preliminary conclusion. Samples for DNA analysis were collected, but the results are not expected for another year. The saint's legend says that in the king's final battle, the enemy swarmed him, and when he fell to the ground they gave him wound after wound until he lay half dead. They then taunted him and finally cut off his head. The remaining bones have at least nine cuts inflicted in connection with death, seven of them on the legs. No wounds have been found on the ribs or the remaining arm bone, which probably means that the king wore a hauberk but had less protected legs. Both shin bones have cuts inflicted from the direction of the feet, indicating that the victim lay on his front. A neck vertebra has been cut through, which could not have been done without removing the hau berk, i.e. not during battle. This confirms that there was an interlude, as described by the taunting in the legend, between battle and decapitation. At no point do the documented wounds gainsay the account of the fight given by the much later legend.
