- Secondary Outcome Measures
Name Time Method 1. Equation for the relationship between MAPSE and left ventricular ejection fraction <br/ ><br>2. Mean/Median time taken to measure MAPSE and left ventricular ejection fraction by modified Simpson’s method which will be compared using paired t-test or Wilcoxon <br/ ><br>Matched-Pairs Signed Ranks Test <br/ ><br>3. Comparison of ejection fraction from our equation, equation given my Matos et al <br/ ><br>and modified Simpson’s method using ANOVA test or Friedman test <br/ ><br>4. Validation of derived equation by calculating bias and precision as compared to the other two methods using Bland Altman analysis. <br/ ><br>5. Cutoff value of MAPSE to predict low left ventricular ejection fraction using receiver operating characteristic (ROC) curve analysis.Timepoint: At the end of the study
