International consensus statements recommend routine reporting of incidental CAC with visual grading and management prompts. However, real\u2010world adherence to these recommendations remains variable, and no data currently exist for New Zealand.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We conducted a retrospective observational study of patients presenting with acute myocardial infarction (MI) to Tauranga and Whakat\u0101ne Hospitals between January 2021 and December 2023. Patients with ST\u2010elevation or non\u2010ST\u2010elevation MI were included; type 2 MI was excluded. Radiology reports from prior NGTCT performed within 5\u2009years of admission were reviewed to assess CAC reporting and grading. Demographic data were obtained from local electronic health records, and cardiovascular risk factors were extracted from the Aotearoa New Zealand All Cardiology Services Quality Improvement registry.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>After exclusions, 1602 patients were admitted with acute MI, of whom 269 (16.8%) had a prior non\u2010cardiac NGTCT. CAC was reported in 70 reports (26%), with visual severity grading provided in 14 (20%). Only two reports (3%) mentioned CAC in the conclusion, and none included a management recommendation. Most ungraded reports used descriptive terminology rather than standardised severity categories. Modifiable cardiovascular risk factors among those with unreported CAC were common, including current or former smoking (83%), hypertension (57%), elevated total cholesterol (41%), elevated LDL cholesterol (41%) and raised HbA1c (27%). CAC reporting was lower in patients aged &lt;\u200955\u2009years and did not differ between M\u0101ori and New Zealand European\/P\u0101keh\u0101 patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>CAC is infrequently reported and rarely graded on NGTCT in regional New Zealand patients who later present with MI, despite strong international recommendations. Given the high prevalence of modifiable risk factors and the potential impact on cardiovascular risk stratification and prevention, routine standardised CAC reporting with inclusion of brief management guidance should be implemented.<\/jats:p>\n
