Introduction: Readmission after acute myocardial Infarction is a challenge in health care. Guidelines recommend early follow-up as those who do not have established follow-up are 10 times more likely to be re-hospitalized. This allows for close review of cardiac symptoms and medications. While there is substantive data about early follow up in the obstructive ST-Segment Elevation Myocardial Infarction (STE-Obstructive) populations improving readmission rates, there are minimal guidelines regarding follow up for STE-MINOCA patients.

Hypothesis: Does time to post-discharge outpatient care impact rate of readmission between STE-Obstructive and STE-MINOCA patients?

Methods: A single center, retrospective cohort study analyzed demographics and discharge pathways of patients meeting STEMI criteria who underwent coronary angiography. Discharge medications, follow up appointment, and readmissions were examined. Simple and multiple logistic regression analyses were used to explore the association between discharge pathways and clinical factors in two STEMI populations.

Results: 377 of 433 patients survived discharge with a median age of 59. Of those who survived, 63.9% were male, 44.3% Black, 30.2% Hispanic, and 82.7% had government-issued insurance. STE-Obstructive patients had significantly higher rates of follow up (p=0.0006) and earlier than STE-MINOCA patients (p=0.052) (Table 1). Despite differences in follow up, readmissions for cardiovascular issues were not significantly different between the STE-MINOCA and STE-Obstructive patients. Of note 64% of STE-MINOCA patients who were readmitted did not have follow up prior to readmission.

Conclusions: STE-MINOCA patients had longer time to follow up and less follow up than STE-Obstructive patients. Readmission rates between the two groups were similar. Further studies are required to explore the role of earlier follow up in STE-MINOCA clinical trajectory.
