Comparison of cardiac examination results between patients with increased pulmonary pressure and those with normal pulmonary systolic pressure
| Patients with PH (n = 7) | Patients without PH (n = 33) | p value | |
|---|---|---|---|
| Data are presented as mean (SD). | |||
| DBP, diastolic blood pressure; LVEDD, left ventricular end diastolic dimension; LVEF, left ventricular ejection fraction; MA, mitral peak flow velocity during atrial contraction; ME, mitral peak early diastolic flow velocity; ME/A, the ratio of mitral peak early diastolic flow velocity and peak flow velocity during atrial contraction; MEDT, deceleration time of mitral early diastolic wave; PH, pulmonary systolic pressure >40 mm Hg; RVEDD, right ventricular end diastolic dimension; SBP, systolic blood pressure. | |||
