Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Spearman correlation of TDI s’ with MAPSE and ejection fraction by modified Simpson’s method.Timepoint: Measurements shall be made only once in one patient for the first 60 patients during the stay in ICU for the purpose of study. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Equation for the relationship between TDI s’ & left ventricular EF by Modified Simpson’s method. 2. Mean/Median time taken to measure TDI s’, MAPSE & EF by Modified Simpson’s method using 1 way ANOVA/ Friedman’s ANOVA test. 3. Comparison of ejection fraction from our equation, equation given my Matos et al [3] and modified Simpson’s method using 1-way ANOVA test or Friedman’s test. 4. Validation of derived equation by calculating bias & precision as compared to the other two methods using Bland Altman analysis. 5. Determination of agreement of ejection fraction obtained by TDIs’, MAPSE & modified Simpson’s method. 6. Cutoff value of TDIs’ to predict low left ventricular ejection fraction using receiver operating characteristics (ROC) curve analysis.Timepoint: 1. Calculations will be performed for the values obtained after first 60 patients have been recorded. 2-6. Calculations will be performed after the observations in 120 patients at the end of study Values will be recorded at the time of diagnostic scan & only once in each patient | — |
