A prospective observational study on assessment of left ventricular systolic function by tissue mitral annular displacement and global longitudinal strain in Nstemi patients

Abstract

Background:

The term "ACS" describes collection of ischemic disorders, such as unstable angina, non-ST segment elevation myocardial infarction (NSTEMI), and ST segment elevation myocardial infarction (STEMI), that arise from the rupture of coronary plaque. Many NSTEMI patients have occluded coronary artery. However the occlusion is not easily recognized so they do not get urgent revascularization therapy. Prompt detection and treatment of these individuals may reduce infarct size and improve survival. The assessment of LVSF was evaluated by various echocardiographic parameters. The quantitative assessment of LVSF was more determine with accuracy by GLS and TMAD methods.

Methods:

Prospective observational study was done in 100 patients and all their clinical information was recorded. ECG and Troponin test were taken which diagnosed as NSTEMI. Those patients were prospectively reviewed for Left Ventricular Systolic Function using GLS and TMAD. GLs and TMAD is statistically analysed using Pearson correlation in NSTEMI patients.

Results:

A total of 100 NSTEMI patients were taken up for the study. A statistically significant association was found between GLS and TMAD measurements. i.e.,P value <0.05. Both the parameters were moderately correlated. Hence, TMAD might also be used as LVSF assessing echocardiographic marker and it was less time consuming.

Conclusion:

The study shows that Tissue Mitral Annular Displacement might also be used as Left Ventricular systolic function and it was less time consuming.
