All cause readmissions to any NHS hospital during the first 60 months of follow-up were analysed from the Hospital Episode Statistics dataset. The relation to the time before, during, and after the COVID-19 pandemic was also investigated. Finally, the primary and secondary diagnoses, as well as any procedure(s) undertaken during readmission, were evaluated.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 101,759 patients were identified (84% male, median age 66.9 years [first and third quartile: 59.7, 73.6]). Of these 69,426 patients, required readmission for any cause. The cumulative incidence of readmission at 12 and 60 months was 42.0% and 68.2%, respectively. The overall readmission rate during the first lockdown to the third lockdown relaxation of the COVID-19 pandemic was 42.0% (ranged: 40.7%-45.0%). No significant differences in readmission rates were observed during the COVID-19 pandemic. At 12 months, cardiovascular-related readmissions accounted for 15% (n\u2009=\u200913 529) of all readmissions, with arrhythmia 25%, heart failure 19% and acute coronary syndrome 15.2%. The primary diagnoses between 13 and 60 months 24.7% (n\u2009=\u200917 162) were arrhythmia, 22.2%, angina pectoris, 19.4%, heart failure 17.1%. The overall incidence of urgent repeat revascularization during readmission at 12 and 60 months was 1.71% and 4.20%, respectively. The primary readmission diagnoses related to the surgical procedure (excluding cardiovascular-related) in the first 12 months was 25.5% (n\u2009=\u200923 047), with non-cardiac chest pain 30.1%, surgical wound disruption\/infection 16.8% and anaemia 15.0%. Between 13 and 60 months, procedure-related primary diagnoses accounted for 26.1% (n\u2009=\u200918 143), of which non-cardiac chest pain 35.6%, anaemia 26.2%, and respiratory tract infection 20.8%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Analysis of this unselected UK cohort reveals that cardiovascular-related readmission represented one-quarter of all readmissions at 5 years after the index CABG.
