Burden and Causes for Hospitalizations Following Coronary Artery Bypass Grafting: A Nationwide Cohort Study

Butt and colleagues examined the incidence and reasons for hospitalizations following coronary artery bypass grafting  (CABG). This study was performed using a Danish nationwide registry including more than 30,000 patients. Within 1 year after CABG, 40% of patients were readmitted at least once, most of them due to a cardiovascular cause. Risk factors for readmission included lower socioeconomic status, preoperative comorbidities, postoperative complications during the index admission, and a longer length of stay in the hospital.
