Clinical Trial Summary
to detect the incidence of CTEPH patients.
Primary outcome To predict CETHP in symptomatic patients after pulmonary embolism episode.
Secondary outcome:
On Echocardiography revealed RV dysfunction which are peak TR Velocity , the RV/LV basal
diameter ratio, flattening of the IVS, RV acceleration time and/or midsystolic notching, IVC
diameter with decreased inspiratory collapse and RA area.
Description:
Chronic thrombo embolic pulmonary hypertension(CTEPH)is a progressive pulmonary vascular
disease characterized by chronic obstruction of major pulmonary arteries with flow-limiting
organized thrombi. In the clinical classification of the 6thWorld Symposium on Pulmonary
Hypertension, CTEPH/chronic thromboembolic pulmonary disease(CTED)are in group4, labeled as
PH due to pulmonary artery obstruction. CTEPH should be considered in PE patients if:(1)they
report symptoms that could be related to CTEPH or with frank right heart failure,(2)the CTPA
used to diagnose acute PE shows signs indicative of CTEPH,(3)they have risk factors or
predisposing conditions for CTEPH. Recurrent venous thromboembolism(VTE),post-thrombotic
syndrome, bleeding ,and functional limitations as important outcome measures of acute PE
treatment , Dyspnea ,anxiety, chest pain ,post-thrombotic panic syndrome, and depression that
lead to persistent functional limitations and/or decreased quality of life have been labeled
as post-PE syndrome(PPS),includes CTEPH. Early diagnosis of CTEPH is important ,as it is the
only form of PH that is potentially curable , but also challenging because signs of right
heart failure only become evident in advanced disease stages and earlier disease stages are
characterized by non specific or even absence of symptoms. The diagnostic work up of
suspected CTEPH ,starts with trans thoracic Doppler echocardiography, In addition to the peak
tricuspid regurgitation velocity , the right ventricle/left ventricle basal diameter ratio,
flattening of the interventricular septum, right ventricular acceleration time and/or mid
systolic notching, inferior vena cava diameter with decreased inspiratory collapse and right
atrial area are used echocardiographic signs to assess the probability of PH.
