SECONDARY outcome

Timeframe: 18 months

Population: To explain the differences in number analyzed for each section below, details are provided: Sensitivity, is calculated as True Positive (TP) / (TP + FN), as such the denominator in this case is 17. Specificity is calculated as True Negatives (TN) divided by True Negatives and False Positives (TN + FP), and the denominator is 563. Positive Predictive Value (PPV) = TP / (TP + FP), with a denominator of 122 and Negative Predictive Value (PPV) = TN / (TN + FN) with a denominator of 458.

This is defined as a positive point-of-care AI prediction for LVEF ≤ 35% (maximum prediction across all stethoscope recording locations) confirmed with echocardiography
