Abstract

Background:

Non-ST-segment elevation myocardial infarction (NSTEMI) constitutes a diverse subgroup of acute coronary syndromes characterised by inconsistent short-term outcomes. Early prognostic evaluation is crucial for enhancing management techniques. The Tei index, a Doppler-derived myocardial performance indicator, combines systolic and diastolic ventricular function and might provide additional prognostic value.

Objective:

To assess the correlation between the Tei index and in-hospital clinical outcomes in individuals with non-ST-segment elevation myocardial infarction.

Methods:

This prospective cohort research comprised 160 patients diagnosed with non-ST-segment elevation myocardial infarction. Transthoracic echocardiography was conducted within 48 hours of admission to ascertain the Tei index. Patients were monitored during hospitalisation for negative clinical outcomes.

Results:

Greater Tei index values were strongly linked to greater rates of heart failure, arrhythmias, cardiogenic shock, longer hospital stays, and deaths in the hospital. In multivariate analysis, the Tei index was identified as an independent predictor of negative in-hospital outcomes.

Conclusion:

The Tei index is a straightforward, non-invasive echocardiographic metric that autonomously forecasts short-term outcomes in individuals with non-ST-segment elevation myocardial infarction.

Recommendations:

Regular measurement of the Tei index during the initial echocardiographic assessment of patients with non-ST-segment elevation myocardial infarction may enhance risk classification and inform early therapeutic decision-making.
