Correlation between Left Ventricular Function with Functional Capacity in Post Infarct Myocard Patients with Heart Failure

In myocardial infarct patient with heart failure, left ventricular (LV) function evaluation after myocardial infarction provides prognostic information. However, the relationship between exercise capacity and LV function has not been fully explored. This study aims to analyze the correlation of LV function with functional capacity in acute myocardial infarct patient with heart failure. From 33 patients who fulfilled the inclusion and exclusion criteria, treadmill and echocardiography were examined (LVEDd, myocardial performance index (MPI), E/E' diastolic function, LV Stiffness). The results are then statistically analyzed using SPSS. The mean LV ejection fraction is 44.27 ± 9.0% by Teich, and 40.55 ± 8.3% by Biplane. The value of the global MPI function is (0.60-0.90). The average E/A ratio is 1.0 ± 0.5, deceleration time (DT) is > 220m/sec, and E/E ratio is 11.46 ± 5.82ms. The functional capacity value is 3.4 (1.1-8.4) METS. There is a significant positive correlation of LV systolic function and functional capacity and significant negative correlation between MPI and functional capacity in myocardial infarct patients with heart failure. Furthermore, there is a non-significant correlation between diastolic function and functional capacity.
