The aim of this study was to describe the natural history of AVC progression in the general population and to identify potential sex differences in factors associated with this progression rate.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Noncontrast cardiac computed tomography was performed in 1298 randomly selected women and men aged 65 to 74 years who participated in the DANCAVAS trial (Danish Cardiovascular Screening). Participants were invited to attend a reexamination after 4 years. The AVC score was measured at the computed tomography, and AVC progression (\u0394AVC) was defined as the difference between AVC scores at baseline and follow-up. Multivariable regression analyses were performed to identify factors associated with \u0394AVC.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Among the 1298 invited citizens, 823 accepted to participate in the follow-up examination. The mean age at follow-up was 73 years. Men had significantly higher AVC scores at baseline (median AVC score 13 Agatston Units [AU; interquartile range, 0\u201394 AU] versus 1 AU [interquartile range, 0\u201322 AU],\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.001) and a higher \u0394AVC (median 26 AU [interquartile range, 0\u2013101 AU] versus 4 AU [interquartile range, 0\u201337 AU],\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt;0.001) than women. In the fully adjusted model, the most important factor associated with \u0394AVC was the baseline AVC score. However, hypertension was associated with \u0394AVC in women (incidence rate ratios, 1.58 [95% CI, 1.06\u20132.34],\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.024) but not in men, whereas dyslipidemia was associated with \u0394AVC in men (incidence rate ratio: 1.66 [95% CI, 1.18\u20132.34],\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      =0.004) but not in women.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>The magnitude of the AVC score was the most important marker of AVC progression.
