- Composite of All-cause Mortality, Need for Mechanical Ventilation, or Need for Mechanical Circulatory Support (MCS) [ Time Frame: 90 Days ]Number of participants experiencing any of the following: All-cause mortality, need for mechanical ventilation, or need for mechanical circulatory support (MCS)
- Delta (Peak Minus Baseline) Troponin Level [ Time Frame: Baseline (Day 1), Day 30, Days 3 and 7 if hospitalized ]Change from initial troponin level to maximum level of troponin among measures taken during hospitalization and at 30 days
- Delta (Baseline to Peak) Brain Natriuretic Peptide (BNP) Level [ Time Frame: Baseline (Day 1), Day 30, Days 3 and 7 if hospitalized ]Change from baseline BNP level (Day 1) to maximum level of BNP among measures taken during hospitalization and at 30 days
- Change in Left Ventricular Ejection Fraction (LVEF) on Echocardiography [ Time Frame: Baseline, Day 30 ]Number of participants experiencing LVEF of < 50% on echocardiogram with failure to show an improvement of ≥ 5% at 30 days
- Delta (Peak Minus Baseline) C-Reactive Protein (CRP) Inflammatory Biomarker Level [ Time Frame: Baseline (Day 1), Day 30, Days 3 and 7 if hospitalized ]Change from baseline CRP level (Day 1) to maximum level of CRP among measures taken during hospitalization and at 30 days
- Delta (Peak Minus Baseline) D-Dimer Inflammatory Biomarker Level [ Time Frame: Baseline (Day 1), Day 30, Days 3 and 7 if hospitalized ]Change from baseline D-Dimer level (Day 1) to maximum level among measures taken during hospitalization and at 30 days. D-Dimer is a small protein fragment present in the blood after a blood clot is degraded by fibrinolysis, so named because it contains two D fragments of the fibrin protein joined by a cross-link.
- Composite Event-Free Survival Over Time (Days) [ Time Frame: Days 0, 10, 20, 30, 40, 50, 60, 70, 80, and 90 ]Participants reaching primary (composite) endpoint were subtracted from event-free survival reported at 10-day intervals
- Number of Participants Requiring Mechanical Ventilation [ Time Frame: 90 days ]
- Number of Participants Requiring Mechanical Circulatory Support (MCS) [ Time Frame: 90 days ]
- Re-hospitalization at 90 Days [ Time Frame: 90 days ]Number of participants released and re-admitted to the hospital within 90 days of enrollment
- All-cause Mortality [ Time Frame: 90 days ]
