Table 2 Comparison analysis of subjects based on LVEF
From: Peak pulmonary artery pressure may be determined by a multiple regression equation - a CE-CMR study
Patient Characteristic | LVEF < 50 % (N = 15) | LVEF ≥ 50 % (N = 39) | P value |
|---|---|---|---|
Left Ventricular EF (%) | 27.3 ± 2.8 | 59.6 ± 0.8 | < 0.0001 |
Systolic blood pressure (mm Hg) | 123.2 ± 6.5 | 130.5 ± 3.2 | 0.2698 |
Diastolic blood pressure (mm Hg) | 73.6 ± 3.1 | 75.8 ± 1.6 | 0.5032 |
Pulmonary artery pressures (mmHg) | 42.1 ± 3.3 | 32.1 ± 1.3 | < 0.0013 |
Pulmonary transit time (sec) | 8.2 ± 1.2 | 5.9 ± 0.2 | 0.0071 |
