Long-Term Hospital Readmission after ST-Elevation Myocardial Infarction: A 3-Year Follow-up from the SEMI-CI Study

Area of Science:

• Cardiology
• Clinical Research
• Public Health

Background:

• ST-elevation myocardial infarction (STEMI) poses significant long-term risks, including hospital readmissions.
• Understanding readmission predictors is vital for post-MI patient management and healthcare resource optimization.

Purpose of the Study:

• To investigate the risk factors associated with cardiovascular readmission within three years following STEMI.
• To identify key clinical and demographic variables that predict readmission in STEMI patients.

Main Methods:

• Secondary analysis of the STEMI Cohort Study (SEMI-CI) involving 867 patients.
• Data collection included demographics, medical history, and clinical data at discharge, with 3-year follow-up via phone and in-person visits.
• Cardiovascular readmission defined as MI, unstable angina, stent thrombosis, stroke, or heart failure; analyzed using binary logistic regression.

Main Results:

• 30.27% of 773 patients experienced readmission within 3 years.
• Higher creatinine levels (OR, 1.73) and history of heart failure (OR, 1.78) increased readmission risk.
• Lower shock index (OR, 0.26) and reduced ejection fraction (OR, 0.97) were also significant predictors.

Conclusions:

• Elevated creatinine, heart failure, lower shock index, and reduced ejection fraction are significant predictors of 3-year readmission post-STEMI.
• Identifying high-risk patients allows for targeted interventions to reduce readmission rates.
• Routine clinical visits should focus on these identified risk factors to improve STEMI patient management.
