Table 3 Relation between the presence of risk stratification of PTE and different investigations
From: Echocardiographic findings in patients with acute pulmonary embolism at Sohag University Hospitals
Variable | High risk, n = 8 | Low risk, n = 32 | P value |
|---|---|---|---|
ECG | |||
Tachycardia | 4 (50.00%) | 13 (40.63%) | 0.89 |
Tachycardia + SQT | 3 (37.50%) | 14 (43.75%) | |
RV strain pattern | 1 (12.50%) | 5 (15.62%) | |
ABG | |||
Normal | 0 (0%) | 4 (12.50%) | 0.55 |
Hypoxia | 5 (62.50%) | 19 (59.38%) | |
Hypoxia and hypocapnia | 3 (37.50%) | 9 (28.12%) | |
d-dimer | |||
Normal (< 500 ng/dl) | 0 (0%) | 0 (0%) | 1.00 |
Positive (> 500 ng/dl in pts < 50 years, and above age-adjusted d-dimer values in pts ≥ 50 years) | 8 (100%) | 32 (100%) | |
