Abstract
BACKGROUND: In many Canadian regions, ST-elevation myocardial infarction (STEMI) patients are managed in a "hub and spoke" model with early repatriation to referring hospitals and rapid discharge pathways that may lead to suboptimal secondary prevention during the critical postdischarge period. We implemented a regional virtual STEMI clinic (VSC) to identify and address gaps in postdischarge care. METHODS: We performed standardized virtual follow-ups for STEMI patients who presented at one tertiary hospital (hub) between November 2023 and November 2024. Standardized VSC follow-up data were used to describe baseline characteristics and secondary prevention interventions. Poisson regression was used to identify baseline characteristics associated with the likelihood of requiring secondary prevention interventions to achieve guideline-directed post-STEMI care. RESULTS: A total of 586 patients were seen in the VSC within a median of 3.9 weeks (interquartile range 2.6) post-STEMI, representing 74.6% of all STEMI patients treated at our centre. Notably, 62.2% of diabetic patients had inadequate glucose control, 19.9% of all patients had a suboptimal lipid status, and 6.6% were newly identified as prediabetic. A total of 73.1% of patients received at least one intervention, including guideline-recommended medication adjustment (35.7%), bloodwork recommendation (31.0%), and referral to cardiac rehabilitation (30.6%). Diabetes was associated with an increase in the rate of new interventions, and every 10-year increase in age was associated with a decrease. The discharging hospital was not a significant predictor of new interventions. CONCLUSIONS: A structured VSC enabled timely post-STEMI follow-up, identifying and addressing key gaps in secondary prevention postdischarge, including lifestyle modification, guideline-recommended medication optimization, and appropriate follow-up care.
