The contemporary health care resource utilization after an acute myocardial infarction (MI) is not well-known. All patients admitted because of MI between January 2015 and December 2021 across 28 hospitals in the Baylor Scott & White Health system were studied. Patient characteristics and outcomes, including all-cause and cardiovascular (CV) rehospitalizations, emergency department (ED) visits, and outpatient visits were evaluated. Of 6,804 patients admitted because of MI, 6,556 were discharged alive. The median age was 69 years, 60% were men, and 77% had non-ST-elevation MI; 17% (1,090) had multivessel disease. The number of patients with first all-cause readmissions within 30 days, 3 months, and 12 months of discharge were 844 (13%), 1,372 (21%), and 2,306 (35%), respectively, with a higher readmission rate in patients with non-ST-elevation MI, previous heart failure (HF), new-onset HF, and left ventricular ejection fraction ≤40%. ED visits at 12 months for any cause were 2,401 (37%), of which 1,321 (55%) were for any CV cause, with a higher incidence in patients with previous HF. Of the 6,556 patients, 4,102 (63%) had at least 1 primary care visit in the past year, 5,009 (76%) had CV specialty visits, and 3,860 (59%) had non-CV visits, with a similar distribution across subgroups. Patients hospitalized with an MI had a high risk of subsequent hospital readmissions and ED and outpatient visits, especially those with a previous HF diagnosis and those discharged with an MI and HF diagnosis.
